But as time passed, and the difficulties associated with a long term project (reality) set in, the release of version 2.0 of the program seemed even farther away than it had at the beginning of the project, and my enthusiasm began to wane. At such times, friends and family always seemed to be there to offer me some heartfelt encouragement, love, and constructive criticism that rekindled my drive and got me over the "slumps" I occasionally found myself in during the software development process. As a result, I honestly feel that EZBREW reflects the nature of these folks as much as it does mine, and, therefore, I also feel that this EZBREW document would not be complete without some formal recognition of these wonderful people who expressed an interest in what I was doing, and offered help and understanding at critical moments. I would first like to thank my friends, Robert and Shari Fertitta, who were always there to apply their oganoleptic talents to the task of evaluating the results of using EZBREW (Robert, that means the [many] times you came to my house because you sensed that a batch was ready and you did not want me giving "inferior" beer to any of my other friends). The many mugs you two tipped in the name of research and program development as well as the time that we spent together talking about beer and brewing and life in general will always be lovingly remembered (by the way - I have another batch in the refrigerator that should be ready soon, and I was wondering...) To my two youngest sons, Aaron and Derek, who never failed to distract me while I was in the midst of programming the code for some of the most intricate sections of EZBREW, thank you. The video games, baseball and basketball cards, board games (I still say that you guys would loose if you played me one-on-one), TV shows, bowling matches (why didn't you tell me that HIGH score wins?), school work, science projects, and soccer games all were a tonic for my soul, and refreshed me beyond belief! It is amazing how the enthusiasm for life that you both have is so infectious! To my oldest son, James, thank you for being interested in girls and cars more than you were in my programming (if I weren't married and I were your age [any age actually], I would probably be in a similar situation) - I don't think I would have made it if all three of you boys had ganged up on me at the same time! Thank you for taking pity on this old fellow. And to my wife, B.J. - words set down on the printed page can not begin to describe the love I feel for you, for your steadfast encouragement, total faith in me, and the unswerving support you have given to me out of the depths of your heart. To say I love you only begins to touch the very surface of the ever strengthening bond we have, a bond based on compassion, trust, and a recognition that we were brought together to be a blessing to each other. (What are you doing tonight, honey? Wanna be blessed?) To all of my friends not mentioned here specifically by name,including all of you ß-testers, I offer a thank you from the bottom of my heart. Each one of you has made a contribution in your own fashion, and EZBREW is the better for all of them. Thanks again to you all for your individual parts in what now follows - EZBREW! Without your day-to-day help I would probably still be working. ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Main Menu ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ╔═══════════════════════════════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ EZBREW ║█ ║ │ GLOSSARY ▄ │ ║ ║ ▀▀▀▀▀▀ ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Home Brewing Applications Software System. ║█ ║ │ MATH ▄ │ ║ ╠═══════════════════════════════════════════════╣█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Written by: ║█ ║ │ TABLES ▄ │ ║ ║ ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Jim Anderson ║█ ║ │ UTILITIES ▄ │ ║ ║ 217 Rooks Drive ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Slidell, LA 70458-1035 ║█ ║ │ HELP! ▄ │ ║ ╠═══════════════════════════════════════════════╣█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Evaluation Version - Release 2.0 ║█ ║ │ EXIT ▄ │ ║ ║ PCC: 089370458100001 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Production Compiled: 08/31/93 ║█ ║ └───────────────┘ ║ ╚═══════════════════════════════════════════════╝█ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ║ ║ ║ ║ ╚════════════ Copyright (C) 1993 Jim Anderson ════════════╝ Please Note the Following: ────────────────────────── ╔════════════════════════════════════════════════════════════════════════╗ ║ ║█ ║ EZBREW is NOT free software!

There is nothing wrong - these functions are reserved for those home brewers who choose to register as EZBREW users. However, the disabled functions in the evaluation release of EZBREW should not prevent you from getting a good feel for what the production release of the program will be able to do for you - enough of a feel in fact that you should be able to decide whether or not you want to register as an EZBREW user and thus be able to perform all of the things contained in this user's guide. ________________________________________________________________________________ Page i INTRODUCTION Background ────────── I tasted my first home brew in the fall of 1973, while attending graduate school at the Pennsylvania State University. A friend of mine gave me one of his many creations when we ran out of "store bought", and to make a long story short, I was not impressed. The beer lacked body, the head fell to quickly, there were "off flavors" galore, and after my breath returned, I figured out that my friend was either a "hop head" or had no taste buds remaining after his stint in the military. His description of how he and his wife had to clean up the closet after the eruption of several bottles successfully squelched any desire I might have had at the time to make some myself! After moving to the southern United States, I was sorry to find that my favorite beer was unavailable in any of the local emporiums, and I resorted to drinking a regional swill, of course all the while looking forward to the trips I made back home so that I could partake of "My Beer." But as my job became more and more restrictive of such travel, I began to consider the possibility of duplicating my favorite libation through home brewing at the house. However, every time I thought about it, the memory of that first home brew returned, and I quickly dismissed the notion and indulged my desire by purchasing an expensive import. One fall day in 1980, while watching the Pittsburgh Steelers destroy yet another hapless NFL team, I took on a bet by a fellow Pennsylvanian and Steelers fan that I could not make a brew as "good" as Iron City Beer, the drink of all real Steelers fans worldwide. After a lot of trial and (mostly) error, I eventually came up with a brew I refer to as "Zwergfalke" (named for the Pigmy Falcon [American Merlin]) - a full bodied, moderately carbonated, sweet, dark beer with a mellow flavor, and just the right amount of hops (they let you know that they are there, but not to the degree that tears come to your eyes and you have difficulty breathing.) And although I lost the bet with my friend, I did win it in a manner of speaking, because Zwergfalke was far and away better than Iron City, and I still make batches of it occasionally - it's that good! Since that time, I have seen a marked increase in the number and quality of ingredients available to the home brewer, and it is easy to see that home brewing is catching on in a big way. I won't belabor the issue, but some of the things I see in home brewing that make it fun for me are: 1. Indulging my desire to make something, to be creative with my hands. If you like to cook, so much the better, because you will find that home brewing does not have to be any more difficult than making a good pot roast! 2. A similar fulfillment of my desire to experiment, to go "where no brewer has gone before." In fact, it is one of the strong points of home brewing that you don't need to do it like everyone else - if it tastes good to you, GREAT. 3. The satisfaction I get in making a beer that is so much better than those I used to drink (some of my friends agree that "The King" has been dethroned). 4. Making a beer at home that tastes great according to my way of thinking, not some regional marketing specialist who sets the standard for the industry based on profit margins. 5. Saving money over those "imports" that, while they taste great, also soak my wallet near to death. My loving wife recently purchased a 6-pack of Pilsner Urquell for me at a cost of $5.99, or $1.00 per 12 oz. bottle. Doing the math, this works out to about $53.00 for a typical home brew 5 gallon batch - ouch! Why not make a batch that tastes great at about one half the price? Sounds good to you? Then read on, fellow brewer! ________________________________________________________________________________ Page 1 6. Sharing my creation with my friends, and the pride I feel while watching it evaporate before my eyes. I may have to watch the New Orleans Saints on TV since most of my friends are Saints fans, but I no longer have to drink the beer of the Saints. And while my friends don't share my feelings towards the Steelers, they do share my pleasure at drinking a truly good beer - a home brew on top of it all! And you will have it a lot easier than I did when I first started making "Real Beer", due to an explosion in the availability of products, equipment, and information you can use to assist you in your development of a great brew. Whether you choose to use a "syrup", spray (powdered) malt, or go all out and delve into all grain mashing, the products and services are there to help you. I love to brew and share beer (and mead too!), but I am just now learning the finer points of home brewing. Quite often while in the midst of a batch, I find myself in need of a system to assist me in my record keeping, experimentation, calculations, information retrieval, etc. And while I have accumulated several great books on home brewing over the years, I just can't seem to find that single bit of information I want when I need it the most. Thus, out of my own frustration mostly, I put my programming skills (such as they are) to work on developing software that would give me what I wanted. I took stock of what I was doing during typical brewing sessions, and tried to put the process into computer code, distilling all of the information I had into the bare essentials. The result, after several rewrites, is EZBREW, which represents an attempt on my part to produce a program that somewhat simplifies the task of developing and using recipes for brewing quality home brew. After using EZBREW for some time, I began to think that some of you home brewers out there might like to use it too, to help you with developing and duplicating recipes. And so, I cleaned up the code, adding the "pretty" graphics, fine tuned the menu system, provided mouse support and the like, and prepared the documentation. After a lot of work, the program was tested, retested, refined, and finally sent to several computer bulletin boards across the country for "downloading" by people like yourself. That brings the story up to date. If you are using a copy of the evaluation version of the EZBREW system, I hope that you acquired it because, like myself, you are a home brewer looking for a system to help you with your brewing. Or maybe you're just looking for a new hobby. If you are new to the home brewing fraternity - welcome! I hope EZBREW will assist you in getting started in this rewarding hobby. For all of you "old timers", I hope it will fill a need you might have in developing that "perfect" brew! So use Release 1.x of EZBREW - try it for 30 days, experiment with an old recipe or make up a new one. And I hope that after you have a chance to use EZBREW, you too will decide to register as a user and get the production release in the near future. Remember, developing that "ULTIMATE" brew will take a lot of experimentation on your part, but where else could sampling the results of your labors be so much fun? ENJOY! Jim Anderson Slidell, Louisiana August 31, 1993 (Happy Anniversary Honey!) ________________________________________________________________________________ Page 2 "A book by any other name..." ───────────────────────────── The EZBREW program, along with it's support files (the EZBREW system), could be considered as being like a crossword puzzle book you are thinking about purchasing. But in this case, you get to read it cover-to-cover and do a lot of the puzzles before you buy. Unlike a crossword puzzle book however, the value of EZBREW lies in the fact that it can be used over and over again without loosing any utility - in fact in some ways it becomes more valuable to you the more you use it. EZBREW comes in two versions - the shareware evaluation version, Release 1.x, and the production distribution (registered) version, Release 2.x and higher. The lower case "x" represents a number to be assigned to specific releases as they evolve and are distributed, and when used in this document, the "x" represents all releases of EZBREW. If you like the shareware evaluation version, I hope you feel free to distribute unmodified copies of it in it's original "compressed" form to friends, computer bulletin boards, or the like, so long as you don't charge a fee for the copy (you can ask for a reasonable fee for the disk, however). After all, you got it for free (at least I hope you did)! If you are a SYSOP, feel free to add a "READ.ME" type file to the compressed EZBREW 1.x file, containing an add for your Bulletin Board if you choose. I ask only that you refrain from offering anything for sale in the ad, and limit it to name, phone, tech. info., etc. If you do register EZBREW, the registered version you receive from me should be treated in some ways as you would handle a book. It is not to be copied, except that you may install the program on a single PC, and you may also make only one (1) backup copy of the compressed form of the EZBREW program/support files for safety "just in case". You can have a single copy of EZBREW on a single PC, just like you can have a single copy of a book only in one library! If friends should ask for a copy, tell them that while you can't give them a copy of the registered version, you can give them the evaluation version in it's compressed form and let them learn the program, it's good points, bad points (shudder to think), and decide for themselves whether or not they feel it's worth registering. Then, they too can get their own registered version, support, etc. just like you did, and I will have one more reason to continue to develop EZBREW in the future. The bottom line is that just like a book, you can't copy the registered version of the EZBREW system to give to your friends - in whole or in part. It's a violation of the copyright on the program and support files, my trust in you, and your honor. But whatever you choose to do - erase the program or register it - thanks for looking over the EZBREW system. I sincerely hope that you will find it useful in your home brewing activities, and that you choose to support the shareware principle. So what is "Shareware" and why distribute programs using this approach? ─────────────────────────────────────────────────────────────────────── Shareware as a concept represents the best of both worlds for you, the prospective program user (home brewer), and me, the program author (another home brewer). You get to try the program for up to 30 days in your own home on your own machine (no high pressure salesmen telling you what you need), putting it through it's paces, learning what it will do, what it won't, and ultimately deciding if you would like to continue to use it. For this hands-on evaluation, you pay nothing. ________________________________________________________________________________ Page 3 If, after examining the program for 30 days, you feel it is not what you thought it was, or are disappointed in any way, you simply destroy (erase) all copies of the program and associated files you have and forget about it. You are free to decide privately, and since the evaluation version of the program comes to you free of charge, you're not out anything except some of your time. But if you do like it, and want to make EZBREW a part of your home brewing activity, you simply send me a registration form and fee, and I will send you a registered version of the program, along with some "Lagniappe" as they say here in southern Louisiana ("freebies") as a thank you for your support. Thus for you, shareware represents a "try it before you buy it" approach to program marketing. You don't have to lay out cash in order to take the program home and give it a test spin. And if you do decide to keep it, your individual registration fee means, among other things, that you can get in touch with me directly, something that commercial software vendors can't always provide. All of this adds up to a winning situation for you. But what about me, you ask? I have put a considerable amount of time into developing the program, coding it, debugging the routines, getting help from friends in terms of suggestions, program critique, and verifying that it works properly on several types/makes of PC's. I have developed, edited, and proofed the documentation, etc. I did this because I thought that there may be others out there who could use the program. And so this shareware evaluation version was released into the computer bulletin board arena, and now I must rely completely on your honesty and sense of fairness. I have worked hard in an attempt to bring you the best that my programming skills can provide, and I ask that you send in your registration form and fee if you honestly believe that EZBREW can help you in your ongoing quest to brew consistently better beer. If not, I ask only that you erase the program and all associated files, and stop using it. Fair enough? Register as an EZBREW user? What for? ────────────────────────────────────── So you may ask, "What do I get for registering EZBREW with you?" Good question. In addition to getting a registered copy of the latest production version of EZBREW, you also get the following: 1. User support. If you have questions on how to operate the program, or just want to make a suggestion on how to improve EZBREW, you can contact me. But the only way to get assistance from me directly is to be a registered user. 2. Some Lagniappe from me I think you will enjoy, in the form of a recipe book on computer disk containing a lot of recipes for all types of ales, meads, lagers, stouts, porters, pilsners, special holiday brews, and the like. And you can use EZBREW while you are trying them out! Such a deal. 3. Expanded capability. The registered version of EZBREW contains several capabilities not available in the evaluation release. The program is written in this fashion so that, using the evaluation version, you can get a feel for what you will be able to do with the full blown production release. However, some of the more useful capabilities are "reserved" for those folks who decide that they really want to use EZBREW (and thus need those functions) and are willing to register it with me in order to get them. If you don't want to use EZBREW, you're out nothing since the evaluation release will give you more than ample capability to decide if EZBREW is for you. If, on the other hand, you would like to be able to do more than what you find in the evaluation version, register today! ________________________________________________________________________________ Page 4 4. Immediate notification of updates, enhancements, and new releases of EZBREW. In fact, only release 1.x (the evaluation version) will be "marketed" as a shareware program, and so only registered users will be notified that newer versions with enhanced capabilities are available. 5. Discounted registration fee on any new release you choose to register. Since you will know what has been done to update the program, you will be able to decide if you want to obtain an upgrade. Thus, you will not have to pay for any capability that you don't want or need right now. This saves you money. 6. A chance at getting a FREE program upgrade. If you register the latest production release of EZBREW, and then are the first one to make a suggestion for improving EZBREW in some substantial manner, and I include your idea in a future release of EZBREW, you will get a copy of that release FREE (one free release per registered user please)! But that can happen only after you register. 7. Continued program development. I like to develop computer software, it's true. And like you, I also enjoy brewing "REAL BEER" at home, for my friends to enjoy with me. And so I put the two together and viola - EZBREW. But in order for me to commit to continued EZBREW program expansion and/or improvement for others, I need to receive a fair compensation for my time. Book authors get a commission on each book sold, musicians get a "cut" of each album, tape, or CD purchased, and the situation is no different for computer software - I am an author, just as if I had written a book. So your registration fee is a "vote" to keep me at work on improvements, etc. that you can take advantage of later! 8. My deepest thanks for your support and honesty. I believe that as a group, home brewers are a good, trustworthy lot, and by registering a copy of EZBREW, you reinforce my beliefs, and demonstrate to me that my trust is not misplaced. This may not seem like much to you, but it will play a great role in determining whether or not I continue to add to and improve EZBREW. Once you decide to take the step and register, you will automatically receive the latest production release of EZBREW upon my receipt of your registration form and fee. Thus, if the newest version of EZBREW is release 3.0, when you resister, you will get 3.0 automatically - the latest and the greatest! One more thing. If you're new to home brewing, you should note that EZBREW is not a replacement for any of the fine instructional materials out there, be it books, videos, newsletters, etc.! Rather, you should consider EZBREW as a calculator designed specifically for home brewing. So visit your local library, read the literature, find out if anyone in your vicinity is brewing, and get some hands on help! Then you will really appreciate EZBREW and what it does. Well, so much for the "generic" program information and background. With that out of the way, let's get on to the really fun stuff - learning the EZBREW System! ________________________________________________________________________________ Page 5 GETTING READY - WHAT YOU SHOULD HAVE What you need to use EZBREW on your computer. ───────────────────────────────────────────── Personal computers (PC's) are being used by more and more people every day for an ever increasing number of functions, and folks in all walks of life are slowly learning that they can be used effectively by nearly anyone. Housewives, truckers, beekeepers, and others have discovered that "friendly" programs are available that can handle things from assistance with tax preparation to providing family entertainment. EZBREW represents an attempt on my part to add to the utility of the PC through a program that somewhat simplifies the task of developing and using recipes for brewing quality home brew. I have tried to make it simple to operate, so that novice and experienced brewers alike would have little or no trouble using it. Throughout this document, and in fact in all documents in the EZBREW system, I will assume that you have a basic understanding of PC's, and how to copy files, make directories, etc. In fact, such a familiarity may be the first thing you need to have in order to use EZBREW. If you don't, I suggest that you get someone who is familiar with PC's to help you install and operate EZBREW for the first time. After that, you should have no trouble running it yourself. You will also need a 100% IBM compatible PC running DOS version 3.x or higher, 640 Kilobytes of available RAM, and a display monitor with a video card of some sort. EZBREW will recognize and adapt itself to CGA, Hercules, EGA, and VGA screens, and can be operated in monochrome, black & white, LCD, and full color mode through command line switches (described later). EZBREW will not run on Apple, McIntosh, etc. computers, so if you have one, you're out of luck - sorry. In addition to the "vanilla" PC described above, you would greatly benefit from having a two button Microsoft or 100% compatible (e.g. Logitech) mouse, and a color display of some sort at EGA or better resolution. The mouse is critical in some areas of the program, but a vast majority of the capability in EZBREW does not require one. Of course, you will need to load the mouse "driver" prior to loading EZBREW (usually with a command such as "MOUSE" of all things). The higher resolution color display will make things "prettier" for you and thus somewhat easier to use. In addition, you can configure EZBREW to use 43 or 50 line display if that is supported on your machine, and this has advantages if you want to display long lists of items without having to "scroll" through them (more on this later). But for me, I prefer the standard 25 line display for clarity since "these old eyes just do not work so good no more!" Finally, any kind of printer would be a nice addition, since it would permit you to capture information as you generate it. For example, if you have not reset your PC to any great degree, you can, at any time during an EZBREW session, press either [Shift] key, and while holding it down, press the [Print Screen] key to get a printout of all of the information on the screen at that time. One more thing -- although I have not mentioned a hard disk, if you do have one, you should copy the EZBREW system onto it and run EZBREW from there. Otherwise, things may be VERY SLOW! Installing EZBREW on your computer. ─────────────────────────────────── Copy the single file that you receive/download to a directory on you hard disk (like a directory called "BREW" or something like it maybe?), "change" to that directory, and type in the name of the file that you copied, without the ".EXE" on the end (e.g. "EZB10"). This is, in reality, a self extracting compressed file, and once the run is finished, you will have all of the files you should need in the directory you created and "changed" to. ________________________________________________________________________________ Page 9 Files that you should have. ─────────────────────────── After running the self extracting file, "EZBxx.EXE", you should find the following EZBREW files on your disk. In all cases, the lower case "x's" in the file names will be replaced by a number, depending on the specific release that you have obtained. Make a note of that number for later use. SELF EXTRACTING, COMPRESSED FILE: 1. EZBxx.EXE Compressed file containing the EZBREW system. BATCH RUN FILE: 2. EZBREW.BAT Batch file for running EZBREW. MAIN EXECUTABLE: 3. EZBREWxx.EXE EZBREW main program for the release that you have. SUPPORT & DATA FILES: 4. EZBREW.GLS Glossary of home brewing terms. 5. EZBREW.HLP EZBREW help file. 6. EZBREW.INF Information about this version of EZBREW. 7. EZBREW.REF Bibliography of books, newsletters, etc. 8. DEGEXT.DAT Degrees of extract table. 9. EFFIENCY.DAT Mashing and sparging efficiencies. 10. HOPSAAU.DAT Alpha acid values for various hops varieties you might use. 11. HOPSUTIL.DAT Boil time versus alpha acid utilization efficiencies. 12. IBUTYPE.DAT Suggested International Bittering Unit levels. 13. SG_BRIX.TAB Specific gravity / Brix (Balling) conversion table. 14. TEMPCORR.DAT Corrections for specific gravity readings. 15.

EZBREW.DOC Users manual for the release that you have. REGISTRATION FORM: 18. REGISTER.DOC Registration form for you to use. COMMENTS FORM: 19. COMMENTS.DOC Form for sending in your comments. PRINTER TEST: 20. PRINTER.TST ASCII file that you can print (1 page) to test your printer before printing out the entire user's guide! LAGNIAPPE FILE: 21. CAT2.TXT A file full of great recipes! (With registered version only.) ________________________________________________________________________________ Page 10 EZBREW BASICS Starting the EZBREW Program. ──────────────────────────── I have tried to make it easy for you to run EZBREW from DOS. A special file called a "Batch" file ("EZBREW.BAT") has been put together and should be used the first couple of times that you start the EZBREW program, since it will check to be sure that all files needed by the program exist. If so, it will launch you into the program - if not, it will give you an error message and you should review the "Files that you should have" section of this manual to find out what file(s) you don't have! To execute the "batch" file, "change" to the EZBREW directory and simply type: EZBREW /.. /.. /.. [┘ Enter] where the "/.." are replaced any "command line switches" you might choose to use (you don't actually type "/.."; the ".." are replaced with commands sent to EZBREW when you start it - see the following section for a description of "command line switches"). This will place you into EZBREW at the "Main Menu" or "Opening Screen" level if no errors are detected. After you have used the "batch" file once or twice, and no errors have been reported, you can type the following to get direct access to EZBREW: EZBREWxx /.. /.. /.. [┘ Enter] where the lower case "xx" is replaced by the appropriate number you noted when looking at the files in the "Files that you should have" section of this manual. Command Line Switches. ────────────────────── As mentioned earlier, several "command line switches" are available for your use. These switches allow you to adjust the operating mode of EZBREW to better match your PC setup, especially where the type of display and use of a mouse are concerned. To review the switches that are available, you simply type (at the DOS prompt): EZBREW /? [┘ Enter] The screen will clear, and you will see: To run EZBREW, type the following: EZBREW {/bw /lcd /-m /43 /50 /?} where: /bw - monochrome display mode. /lcd - for use with lcd displays. /-m - ignore mouse if present. /43 - 43 line mode (if supported). /50 - 50 line mode (if supported). /? - for this help screen. Commands in the brackets are optional and may be input in any order. ________________________________________________________________________________ Page 13 So if you wanted to put EZBREW in monochrome (black and white) mode, you would type the following (case of the letters is not important): EZBREW /bw [┘ Enter] Several of the switches can be combined by typing each one you want, with a blank space in between (they can be typed in any order), like: EZBREW /lcd /43 /-m [┘ Enter] which would direct EZBREW to set up for an LCD screen with 43 lines, and to ignore the mouse if it is active. Program default settings (used if you don't specify anything else) are: DISPLAY: 16 Colors RESOLUTION: 25 Lines by 80 Columns. MOUSE: If one is detected (active), use it. The Opening Screen. ─────────────────── Each time you enter EZBREW from DOS, the first screen you see will look a lot like this: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ <┐ Main Menu ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ This is the ▀▀▀▀▀▀▀▀▀▀▀ This is the ║ │ α- ACIDS ▄ │ ║ "Mouse Cursor" "Action Window" ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ╔═══════════════════════════════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ EZBREW ║█ ║ │ GLOSSARY ▄ │ ║ ║ ▀▀▀▀▀▀ ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Home Brewing Applications Software System. ║█ ║ │ MATH ▄ │ ║ ╠═══════════════════════════════════════════════╣█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Written by: ║█ ║ │ TABLES ▄ │ ║ ║ ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Jim Anderson ║█ ║ │ UTILITIES ▄ │ ║ ║ 217 Rooks Drive ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Slidell, LA 70458-1035 ║█ ║ │ HELP! ▄ │ ║ ╠═══════════════════════════════════════════════╣█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Evaluation Version - Release 2.0 ║█ ║ │ EXIT ▄ │ ║ ║ PCC: 089370458100001 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Production Compiled: 08/31/92 ║█ ║ └───────────────┘ ║ ╚═══════════════════════════════════════════════╝█ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ The area above ║ ║ this note is the ║ ║ "Side Menu". ╚════════════ Copyright (C) 1993 Jim Anderson ════════════╝ This is called the opening screen or Main Menu, and is the area of the program from which all of the other functions in EZBREW are accessed. You can tell that you are at this "level" in EZBREW because there is a little "floating banner" saying "Main Menu" near the top of the screen (just under the heading that states "EZBREW Release 2.0"). In fact, this "banner" will generally appear at the top of the screen, so you will always know just what you're doing! ________________________________________________________________________________ Page 14 Along the left side of the display is the "Side Menu", which lists all of the options available to you from the Main Menu. It is from this menu that all major EZBREW functions are activated. The Side Menu is active only when you are at the "Main Menu" level of the program (more on this later). If each of the options in the Side Menu has a letter in it's name that stands out from the rest on the display you are using (called it's "hot" letter), you are using EZBREW in a mode that supports "hilighting"; if not, simply ignore any reference to hilighting you find in this document. The right side of the display is taken up by the "Action Window", an area in which you will be doing all of your work. The "floating banner" mentioned above, as well as additional menus, requests for information, notes, the results of your inputs, etc. will all be put here, so you can think of it as your computerized "scratch pad". You can also see the mouse "cursor" that appears as a "smiley face" (). This is what you will use as a pointer if the mouse is active when EZBREW is loaded into your PC and you choose to use it. When you first "fire up" EZBREW, the Action Window will contain the "Title Screen", which will appear only when you start the program. It contains my Name and Address, your Production Compile Code (PCC) and Date, and the Release Number. These bits of information will be quite important to you if you want to get in touch with me about EZBREW. You can also recall this data during a "session" with EZBREW (more on that later). The bottom left corner of the screen is reserved for displaying information that you might like to know at certain times in the EZBREW program, such as the efficiency of your mashing and sparging, etc. (Don't worry about the terms - you will learn them, and EZBREW can help!) Selecting and Activating an Option. ─────────────────────────────────── In order for you to do something in EZBREW, you need to activate an option. You do this by first selecting the option you wish to perform, and then activating it as described below! Simple enough. You activate an option in one of three ways. First, you can use the "cursor" keys on your computer keyboard to select an option that you want, and then press the [┘ Enter] key to activate it. The cursor keys are those keys on the keyboard normally used to move the screen "text" cursor around the screen when doing word processing, and their names describe their function. Not very surprisingly then, the cursor keys have an up arrow (move up), down arrow (move down), left arrow (move left), right arrow (move right), the words "Page Up" or "Pg Up" (skip up a page), "Page Down or "Pg Dn" (skip down a page), "Home" (go to the beginning), and "End" (go to the end). In EZBREW documents, the cursor keys are represented by [UP], [DOWN], [LEFT], [RIGHT], [PAGE UP], [PAGE DOWN], [HOME], and [END] respectively. Back to the opening screen. Notice that when you first enter EZBREW, the "EXIT" option is "selected." You know this since the selected option has a set of left/right arrowheads on it (" EXIT "). Also, on color displays, the letters "E", "I",, and "T" are white, not black like the unselected options. Now try pressing [UP] (the one with the arrow pointing towards the top of the keyboard)... (The examples used in this document may not exactly agree with the screens that you actually see on your computer.) ________________________________________________________________________________ Page 15 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Main Menu ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ╔═══════════════════════════════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ EZBREW ║█ ║ │ GLOSSARY ▄ │ ║ ║ ▀▀▀▀▀▀ ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Home Brewing Applications Software System. ║█ ║ │ MATH ▄ │ ║ ╠═══════════════════════════════════════════════╣█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Written by: ║█ ║ │ TABLES ▄ │ ║ ║ ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Jim Anderson ║█ ║ │ UTILITIES ▄ │ ║ ║ 217 Rooks Drive ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Slidell, LA 70458-1035 ║█ ║ │ HELP! ▄ │ ║ ╠═══════════════════════════════════════════════╣█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Evaluation Version - Release 2.0 ║█ ║ │ EXIT ▄ │ ║ ║ PCC: 089370458100001 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Production Compiled: 08/31/93 ║█ ║ └───────────────┘ ║ ╚═══════════════════════════════════════════════╝█ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ║ ║ ║ ║ ╚════════════ Copyright (C) 1993 Jim Anderson ════════════╝ The arrowheads moved up to the next option, namely "HELP!", indicating that the HELP! option has been selected. You can select an option from the Side Menu only with [UP] and [DOWN]. Try pressing [UP] again now... If you continue to press [UP], you will eventually reach the "°EXTRACT" option, and if you press [UP] once more, the arrowheads jump around to the bottom of the list, and "EXIT" is now selected. Pressing [DOWN] will cause the reverse to take place. This is called "wrap around", and makes it easy for you to go from the bottom of the list to the top. Once you have selected the option you wish to activate, press [┘ Enter], and you're off! (Don't do that just yet.) So, in review, you can use the [UP] or [DOWN] cursor keys to select an option from the Side Menu, and then press [┘ Enter] to activate it. The second way to activate an option from the Side Menu is to type the "hot" letter of the option you wish to activate. (The "hot" letter for each option is yellow on color displays, and appears different than the remaining letters on non-color units if hilighting is supported.) This method is "faster" than the first, since pressing a single letter selects the option and immediately activates it all in one keystroke. Since you don't have to press [┘ Enter], it is like a short cut. The result is exactly the same as if you would have moved the arrowheads with the cursor keys, and then pressed [┘ Enter]. Try this - make sure you are at the "Main Menu" (remember the "floating banner" at the top of the action window?), and press the [H] key on your keyboard now (you can type [H] or [h], the case of the letter does not matter - both capital and small letters work)... ________________________________________________________________________________ Page 16 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Help Menu ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌──────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Help with ... │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │▓▓▓▓▓°EXTRACT▓▓▓▓▓│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ α- ACIDS │██ └>"Smiley" is ║ │ MATH ▄ │ ║ │ REFERENCES │██ visible only ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ GLOSSARY │██ if the mouse ║ │ TABLES ▄ │ ║ │ MATH │██ is active & ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ TABLES │██ you have it ║ │ UTILITIES ▄ │ ║ │ UTILITIES │██ "turned on". ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ HELP! │██ ║ │ HELP! ▄ │ ║ │ EZBREW │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ EXIT │██ ║ │ EXIT ▄ │ ║ └──────────────────┘██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ████████████████████ ║ └───────────────┘ ║ ║ ║ For information about a particular option, select one. ▄ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ║ ║ ╚════════════ Copyright (C) 1993 Jim Anderson ════════════╝ Several things happened all at once. Notice that all of the "hot" letters for all options on the Side Menu have disappeared (if you are using a display mode that supports hilighting), an indication that the Side Menu portion of the screen is no longer active. In fact, you are actually in the HELP! option (the word "HELP" is all white now). Another indication of this is that the floating banner now says "Help Menu", so you know that you are no longer at the Main Menu level of EZBREW. Probably the biggest difference is that the Title Screen is now gone, and you are confronted with a floating box that contains several options to choose from. This is another form of a "Menu", or list of things you can choose to do. Since we don't want to do any of these yet, press the "Escape" key ([ESC]) once to get out of the HELP! option. You now find yourself back at the Main Menu, with the HELP! option still selected. So the second way to activate an option is to type the "hot" letter corresponding to the option you want, remembering it is not case sensitive. The third way to activate an option is to use the mouse, and is, for me anyway, the easiest of the three to use. Using your mouse, if activated, move the "smiley face" (called the mouse cursor from now on) to the HELP! option (anywhere on the bar), and press and release the LEFT mouse button. BINGO! You're right back to the HELP! menu, just like before. To get out, press and release the RIGHT mouse button, or press [ESC]... Back to the Main Menu! So the third and final way to activate an option is to "click on it" using the LEFT mouse button. By "click on it" I mean that you place the mouse cursor over the item, and then press and release the appropriate mouse button. ________________________________________________________________________________ Page 17 Selecting Items from "Sub-Menus". ───────────────────────────────── Activate the HELP! option using any of the three methods you just learned, and you will see the following: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Help Menu ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌──────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Help with ... │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │ °EXTRACT │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ α- ACIDS │██ ║ │ MATH ▄ │ ║ │ REFERENCES │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ GLOSSARY │██ ║ │ TABLES ▄ │ ║ This is the ──> │▓▓▓▓▓▓▓MATH▓▓▓▓▓▓▓│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ "Selection Bar" │ TABLES │██ ║ │ UTILITIES ▄ │ ║ │ UTILITIES │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ HELP! │██ ║ │ HELP! ▄ │ ║ │ EZBREW │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ EXIT │██ ║ │ EXIT ▄ │ ║ └──────────────────┘██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ████████████████████ ║ └───────────────┘ ║ ║ ║ For information about a particular option, select one. ▄ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ The list of items that appears in the box ("Help with ...") in the Action Window is called a "Sub-Menu". This type of menu appears throughout EZBREW, and provides you with a list of all of the things that you can do that are somewhat related in function as defined by the menu option that you selected prior to the appearance of the Sub-Menu. For example, the menu above contains all of the subjects that you can get help with at this point in the program. Notice that this particular list looks suspiciously like the Side Menu - it was designed to! The item currently "selected" will be located on a "Selection Bar", as can be seen in the above example or on your screen. Since they don't contain a "hot" letter, individual items in a Sub-Menu can only be activated in one of two ways: (1) using the [UP] or [Down] Cursor Keys and pressing [┘ Enter], or (2) "click and release the LEFT mouse button" technique. Note that if you use the cursor keys, you can press [Up] while at the top of the list, and the selection bar will jump to the bottom of the list, meaning that "wrap around" is in effect. It works both ways, so pressing [Down] while at the bottom of the list will jump you to the top! Try it. Using one of the two techniques just mentioned, activate the "Math" Item from the HELP!

The floating banner now announces the fact that you are receiving "EZBREW Help Information", and the "title" of the help box in the Action Window reads "MATH", so it's just got to be help for the "MATH" option! While you are here, notice that the help box has a small solid square in the upper left corner. Place the mouse cursor on this square, and click the LEFT mouse button... the help box vanishes, and you're back to the HELP! menu. (Pressing [ESC] will do the same thing.) This is the way that you "close" or erase a help window. The All Important "Escape" Key. ─────────────────────────────── What happens if you get into something that you don't want to be in?

You can simply keep an eye on the banner and you should be able to determine where you are at anytime. If you press [ESC] at the Main Menu level, you will begin the exit procedure that will "shut down" the EZBREW program and return you to DOS. See the sections in this manual on "Getting out of EZBREW" or the "EXIT" program option for more information. The "Scroll Menu" ───────────────── Another type of Sub-Menu is called the "Scroll Menu". In this type of menu, you are given the chance to select one (and only one) item from all of those shown. The menu itself looks similar to those you have seen up to now, with the exception that there may be some arrows and a shaded "Position Bar" along the right side of the box, indicating that there are additional items available to you that you just can't see on the list as displayed. In order to see them, use the [UP], [DOWN], [PAGE UP], [PAGE DOWN], [HOME], or [END] cursor keys, or click with the LEFT mouse button on either of the arrows to move the Selection Bar from item to item. You can also "drag" the Indicator (see the following Figure) on the Position Bar by clicking the LEFT mouse button while the mouse cursor is anywhere on the Position Bar. You will see the Indicator moving up and down the Position Bar, showing you where in the total list you are - near the top of the Position Bar indicates that you are near the beginning of the list of items, the bottom of the Position Bar means you are near the end of the list. To select/activate an item, move the Selection Bar to it and press [┘ Enter], or click on it using the LEFT mouse button. To abort without making a selection, click the RIGHT mouse button or press [ESC]. ________________________________________________________________________________ Page 20 For example, if you go to the Main Menu level of EZBREW, and activate the GLOSSARY option, the following list will appear (or something similar to it): ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Glossary ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ╒══════════════════════════╕ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Define │ ║ │ REFERENCES ▄ │ ║ ╞══════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ A.A.U. ──── Go "Up" ║ │ GLOSSARY ▄ │ ║ Terms to ──│ ACETIC ACID ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Define │ ADJUNCTS ▓──── Indicator ║ │ MATH ▄ │ ║ │ AEROBIC ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ ALCOHOL ░██ ║ │ TABLES ▄ │ ║ Selection ──│▓ALE▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓░──── Position ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Bar │ ALPHA ACID ░██ Bar ║ │ UTILITIES ▄ │ ║ │ ALPHA-AMYLASE ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ ANAEROBIC ░██ ║ │ HELP! ▄ │ ║ │ ATTENUATION ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ BALLING ░██ ║ │ EXIT ▄ │ ║ │ BARREL ──── Go "Down" ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╘══════════════════════════╛██ ║ └───────────────┘ ║ ████████████████████████████ ║ ║ ║ ║ Select a term for EZBREW to define. ▄ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ╚════════════ Copyright (C) 1993 Jim Anderson ════════════╝ Notice the Position Bar along the right side of the box, with the arrows at the top (pointing "up") and bottom (pointing "down"). Notice also that one of the items appears to be on a different background than the rest. This is the selection bar, and it is used to hilight the item that is currently selected. Use [DOWN] to move the selection bar down, and as you do so, watch how the indicator moves down the Position Bar, indicating that you are moving away from the beginning of the file towards the end of the list. If you use [UP], the indicator will move up also. It may take several "real moves" to make the indicator move, so you are looking at a "close enough" indication of where you are in the file. You can also move the selection bar with the mouse as stated. Try this, place the mouse cursor on the "down" arrow at the bottom of the Position Bar, and click and release the LEFT mouse button once. You should notice that the selection bar moves down one line to the next item in the list. Repeatedly clicking on the arrow will repeat the process as fast as you can click - try it. Now if you press and HOLD the LEFT mouse button down while on either arrow, watch out! The selection bar will first move one item in the direction of the arrow, pause momentarily, and then ZOOM off very quickly. You would have to have good eye/finger coordination to stop it just where you wanted it! Notice also that if you "drag" the Indicator on the Position Bar, the Selection Bar moves up or down, but it does so very quickly! I like to use [PAGE UP], [PAGE DOWN], [HOME], and [END] to move in "big jumps", and then use the mouse to select the item I want.

When you are finished, return to the Main Menu. The "Tag Menu" ────────────── One additional type of menu will be found in EZBREW - the "Tag Menu" is used to select one or more items from a list, depending on the option that you are in at the time. To a large degree it operates like the Scroll Menu. You first move the selection bar to the item using the cursor keys, and "tag" it by pressing the [SPACE BAR]. You will see a "" appear to the left of the item, indicating that it has been "tagged" for selection. To "untag" it, move the selection bar to it and press the [SPACE BAR] again, and the "" will disappear. You can also use the mouse to "tag" items, by placing the mouse cursor on the item you want, and clicking the LEFT mouse button. To "untag" an item, click on it using the LEFT button again, and the "" will disappear. Once you have tagged all of the items you want, press [┘ Enter] or click on the "< OK >" area at the bottom of the menu, and your selections will be recorded. To get out without continuing (called ABORTING), press [ESC] or click the RIGHT mouse button, and you will return to the previous menu. ________________________________________________________________________________ Page 22 For example, at the Main Menu level, activate the "α- ACIDS" option, then select and activate "IBU" from the menu that appears. Select and activate "IBU" from the box that reads "Calculate What?", and finally choose "2" when asked for the number of varieties you want to use.

Entering Information Requested by EZBREW. ───────────────────────────────────────── At times during your work, EZBREW will ask you to provide information so that the request that you made can be completed. This section describes the ways that you can furnish the information sought. Here is an example. Suppose that your recipe calls for you to add some 76.7° Centigrade water to the boiling kettle. If you don't have a thermometer that indicates temperature in Centigrade units, what do you do? One option is to let EZBREW do the conversion for you. Here's how you would do it... The problem: You want to convert readings given in degrees Centigrade to units you can use, like degrees Fahrenheit, but you don't have your calculator handy, nor do you remember the conversion formula. The solution: EZBREW has this function built in under the "MATH" program option. So, from the Main Menu level, select the "MATH" option... ________________________________________________________________________________ Page 23 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Calculations & Conversions ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌───────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Option? │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞═══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │ %Wt <-> %Vol │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │▓▓▓▓▓°C <-> °F▓▓▓▓▓│██ ║ │ MATH ▄ │ ║ │ Potential Alcohol │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ S.G.

Simply type in a value (use the [-] key for values below zero). The "greyed out" field is replaced by your value as you type along, and if you make a mistake, use the [Backspace] key to "back over" your error and erase it. Then type in the correct value. Did you notice that EZBREW told you that the values you provide had to be between -999.9 and 999.9 degrees. Input data limits appear throughout the program, and if you attempt to use values outside of the range given, results may not be what you expect! For our example, type in the value of 76.7 (the "." is the "period" key), and when you're ready, press [┘ Enter] (you don't have to type the "°" symbol). When asked for information in this fashion, you can ABORT and exit from the program function by pressing [ESC] at any time, pressing [┘ Enter] without providing a value (called a "blank return"), or by clicking the LEFT mouse button when no numbers are in the greyed out area. Thus, in the above example, when asked to "Enter the value to be converted:", simply press [┘ Enter], [ESC], or click the LEFT mouse button before you type any values, or [BACKSPACE] over the values until they are all gone and then press [┘ Enter] or click the LEFT mouse button, and you return to the MATH Menu. The "Choice Box". Another way in which you enter "data" is through the use of a "Choice Box." This form of floating bow provides you with two possible choices that you may select. In our example, EZBREW will next ask you if this a Fahrenheit or Centigrade temperature. You provide "data" to EZBREW by clicking on your selection (or using the "hot" letter), but in this case, EZBREW limits your choices to a large degree. These "choice boxes" will not permit you to use the cursor keys, so the mouse and "hot" letters are all that remain. So click on your choice (or type the "hot" letter) and EZBREW will give you the answer (in our example, click on the "Centigrade" or press "C"). ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Conversions between Centigrade & Fahrenheit Units. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ GLOSSARY ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ MATH ▄ │ ║ ╔═════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ 76.7° C = 170.06° F ║██ ║ │ TABLES ▄ │ ║ ║ ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╟─────────────────────╢██ ║ │ UTILITIES ▄ │ ║ ║ < OK > ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╚═════════════════════╝██ ║ │ HELP! ▄ │ ║ ███████████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ EXIT ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ └───────────────┘ ║ This is an example of an "OKAY" box.

Dave thought through a process that resulted in the determination of the increase in gravity that one "unit" (cup, pound, can, package, etc.) of a substance would provide if added to enough water to make a gallon. So, if one pound of "typical" Light Spray Malt (powder) were used to make a gallon of solution, the gravity would rise from 1.000 (water alone) to about 1.038 (water + Spray Malt). Thus, one pound of Light Spray Malt (powder) has 38 Degrees of Extract. As Dave says to describe his idea, "Simple." Through many trials, Dave tabulated the results of several commonly used brewing materials, such as malts, sugars, grains and the like, and described the process by which Degrees of Extract can be used prior to actual brewing to estimate the Initial Gravity of worts. Using Degrees of Extract, you can calculate the amount of each ingredient to use, get an idea of how the resulting wort will "look", and adjust the amounts as needed "before it's to late." His experiments also showed that there is some natural variability among similar materials that leads to a variation in the increase in gravity noted. Two Crystal Malts, for example, might not produce the same end gravity, all other things being equal. But how do I use Degrees of Extract in my brewing plan you ask? Every time you brew, I answer. The power in Dave's system is that it is simple to understand and use, and now that it is in EZBREW, you don't even have to "sweat the math"! To demonstrate just how you would use Degrees of Extract (°Extract) in planning a brew, let's suppose that you are developing the ULTIMATE brew, "MIDNIGHT ALE", and you want to make sure that the Initial Gravity is around 1.048. You already know what ingredients you want to use, but now the question is just how to go about determining the proper amount of each ingredient to add to your wort. The solution is simple. Start EZBREW and activate the °EXTRACT Side-Menu option.

Of course, as you become more accustomed to EZBREW, you will note that the UTILITIES Side-Menu option contains the capability to edit this table (add, delete, modify, move entries, etc.), so if you have a favorite that's not on this list, you will be able to include it! The right hand column contains a "typical" figure for °Extract that you might expect to obtain from each item in the list. For example, in the above screen, "Jim's Special Beer Honey" is listed as having a °Extract of 48.0, but in reality, this value varies quite a bit, depending on the type of honey you have access to, and the "efficiency" of the honey bees at processing the nectar (yes, I am a beekeeper - why else would honey be on the top of the list!). A comment is appropriate at this point. I'm a firm believer that examples can be used to great benefit in teaching something new. So I have decided to ask you to help me develop a truly GREAT brew we will call "MIDNIGHT ALE" as you learn how to use EZBREW. It will serve to demonstrate the basic operation of the major program options as we reach each one, and since we are developing an ALE recipe, you might want to exit now to the Main Menu and activate the GLOSSARY Side-Menu option and look for the description of an ALE! EZBREW has been developed so that the novice as well as experienced brewer can use it, so if you already know what an ALE is, just go on from here. In order to construct your brew, you "tag" the following items from the list: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Using Degrees of Extract to Develop a Brew ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ┌──────────────────────────────────┐ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ See the │ Use... °Ext │ ║ │ REFERENCES ▄ │ ║ Tag Menu ╞══════════════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Section │Jim's Special Beer Honey 48.0 ██ ║ │ GLOSSARY ▄ │ ║ of this │Pale Malt 34.0 ░██ This is ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ User's │Crystal Malt 25.0 ▓██ a "Tag ║ │ MATH ▄ │ ║ Manual │Black Patent Malt▓▓▓▓▓▓▓▓▓▓▓5.0▓░██ Menu" ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ for a │ Malt Ext.

Normally, spray (powder) malts, sugars, grains, etc. are measured in pounds, so entering a 1.0 for these types of ingredients means that you want to use 1.0 pound. Malt Extract Syrups (like the Alexander's in the original Tag Menu list) may be given in pounds or CANS of a particular size, as reflected in the °Extract figure. The Alexander's Syrup has a °Extract figure of 165.0, so obviously this is for a CAN. This is also indicated in the item name, "Alexander's P.M.E. [Pale Malt Extract] 4# Can". Entering a 1.0 in this case means to use an entire 4 pound can, NOT 1.0 pound! BE CAREFUL! Activate the "< OK >" and provide the amount of each item you want to use as directed by EZBREW (see the next page for our example). You will see a greyed out "input field" by each item in the "Grain" column - simply type in the amount of each item you wish to use and press [┘ Enter] - the value will be recorded and the "input field" will drop to the next GRAIN/EXTRACT item in the list. As you type and press [┘ Enter], you will see that EZBREW is adding all of the values you provide and placing the sum at the bottom of the table, next to the words "Total Extract =". The Total Extract represents the contribution of all of the "fermentables" you are using, and is easy to calculate. (WARNING: The following contains "math" which some readers may find distasteful!) Take the number of "units" of each item and simply multiply by the °Extract per unit. Add up all of these values and you get the Total Extract for the items you are using. After you have provided EZBREW with the amount of the last GRAIN/EXTRACT in the list you wish to use, you will be asked if all is OK: ________________________________________________________________________________ Page 31 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Using Degrees of Extract to Develop a Brew ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ You have chosen these ingredients for your brew: ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ Ingredient °Extract Grain ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ═════════════════════════════════════════════════════════ ║ │ GLOSSARY ▄ │ ║ Jim's Special Beer Honey 48.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Pale Malt 34.00 6.00 ║ │ MATH ▄ │ ║ Crystal Malt 25.00 2.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Black Patent Malt 5.00 0.25 ║ │ TABLES ▄ │ ║ ═════════════════════════════════════════════════════════ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Total Extract = 242.49 ║ │ UTILITIES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ HELP! ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╔══════════════════════════╗ ║ │ EXIT ▄ │ ║ ║ Are the entries OK? ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ ║██ ║ └───────────────┘ ║ ╟──────────────────────────╢██ ║ ║ ║ < Yes > < No > ║██ ║ Mashing = 100% ║ ╚══════════════════════════╝██ ║ Sparging = 95% ║ ████████████████████████████ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ Answering "No" will return you to the "Enter the amount..." screen, where you can alter any value you wish to. "Hold on, Jim! Not so fast!", you say. "I have been doing this on my hand held calculator as you were explaining it, and I think I found a bug in the software!" "Where?", I ask. You reply, "So far in the example you are using, if I take the °Extract for each malt and multiply by the number of "units" of that malt being used, and then add it all up like you said to, I get:" (Pale) + (Crystal) + (Blk. Patent) ────────────── ────────────── ───────────── (34.00 * 6.00) + (25.00 * 2.00) + (5.00 * 0.25) = (204.00) + ( 50.00) + ( 1.25) = 255.25 "Where on earth did EZBREW come up with a Total Extract of 242.49?" Noting the look of confusion in your eyes, I reply, "Good question!" (For those of you who don't like math, you can skip the next several paragraphs without loosing anything. EZBREW is NOT flawed!) My Explanation: It all lies in the two numbers displayed in the bottom left corner of the EZBREW screen, directly under the Side-Menu. These values indicate the efficiency of two processes in your overall brewing operation, referred to as "Mashing" and "Sparging". Now where do you suppose you might find out what these two words mean? When dealing only with Malt Extracts (be they powders or syrups) and sugars, these values mean nothing, and your calculations would be appropriate (and correct). But since our example contains actual GRAINS (like the Pale, Crystal, and Black Patent Malts), additional steps are required in order to get the °Extract that we actually see in the wort from these items. Grains must be "mashed", a process in which starches are converted to fermentable sugars that ________________________________________________________________________________ Page 32 actually provide the °Extract that we are interested in (see the books by Dave Line, Charlie Papazian, or Byron Burch for a description of the mashing process). Of course we are interested in getting all of the starch converted to sugar that we can, since our yeasts feed on the sugars, not the starches! In order to determine whether or not mashing is complete (all of the starches have been converted to sugars), iodine is used. Since iodine will turn "black" in the presence of a starch (remember high school science class with the potato?), it can be used as an "indicator" agent. Normally, mashing is continued until a drop of iodine placed on a few drops of the wort (on a white dinner plate) does not turn "black", indicating that all of the starch has been converted to sugar (called the "Starch End Point" by those familiar with mashing). At this point, we have a "sweet wort". If Starch End Point is reached, the efficiency of the mashing is said to be 100% - you can't do any better than this! In other words all of the available starch in the wort has been converted to sugar. If you terminate your mash prior to this time, your efficiency drops below 100%, and you do not convert all of the starches in the wort to sugars. There may be a real reason for doing this, but normally mashing continues until Starch End Point is achieved. EZBREW comes to you set up for "normal" mashing, that is, the program is set up for mashing operations that reach Starch End Point. Thus, the "Mashing =" value at the bottom left corner of the EZBREW screen indicates 100%. If you have not reached starch end point, the value for Total Extract calculated by EZBREW will be somewhat HIGH. You can adjust the mashing efficiency value in the UTILITIES Side-Menu option if you know it or measure it from a test batch. Once mashing is finished, the "goods" as they are now called must be "sparged" with hot water. The goods are "filtered" through a device that acts like a strainer, allowing the sweet wort to pass, but holding all of the grains back. Since the grains act like little sponges, some of the wort is trapped in the wet mass of grains left behind, and thus hot water is slowly passed through them in an attempt to extract every speck of sweet wort possible! If you could get it all, your sparging efficiency would be 100%, and you would be toasted by brewers around the country! But alas! It seems almost impossible to achieve such perfection! And thus, some of the sweet wort is left behind in the grains, and you might get only 95% of the total wort available. In this case, your efficiency would be 95% (surprise!). Since most brewers can achieve this efficiency with some care, this is the value used by EZBREW (reported as "Sparging =" in the lower left corner of the screen). The two efficiencies act together to set the upper limit of extract available to you for your brewing. You use them to compute the Total Extract as follows. For each GRAIN in your recipe, multiply the number of units used by the °Extract for the GRAIN, and then multiply the result by the DECIMAL mashing efficiency. Multiply the resulting value in turn by the DECIMAL sparging efficiency to calculate the °Extract that we actually get from the GRAIN. (Using the DECIMAL value means converting the % value by throwing away the "%" sign, and dividing by 100. Thus, 100% becomes 1.00, 95% becomes .95, 5% becomes .05, etc.) The calculation for the example we are using looks like this: For each GRAIN being used, calculate the following (the "*" means multiply): Number of "units" * Item's °Extract * Mash Efficiency * Sparge Efficiency ________________________________________________________________________________ Page 33 For the GRAINS in our example, we would get: Pale Malt: ────────── (6.00 * 34.00) * 1.00 * 0.95 = (204.00) * 1.00 * 0.95 = 193.80 Crystal Malt: ───────────── (2.00 * 25.00) * 1.00 * 0.95 = ( 50.00) * 1.00 * 0.95 = 47.50 Black Patent Malt: ────────────────── ( 0.25 * 5.00) * 1.00 * 0.95 = ( 1.25) * 1.00 * 0.95 = 1.19 Adding up all of the values: ────── ──────────────────────────── Total Extract = 242.49 And there is the answer to your question! Since the sparging is less than perfect, we loose 5% of the total °Extract available to us in the spent grains remaining in the "lauter tun" (look that one up!). This represents: 255.25 (possible) * 0.05 (loss) = 12.76 °Extract remaining in the grains! Of course, for those of you who like math, you could multiply the number of "units" by the °Extract for each GRAIN, add them all up, and then multiply by the Mashing and Sparging efficiencies to arrive at the same answer: [(6.00 * 34.00) + (2.00 * 25.00) + (0.25 * 5.00)] * 1.00 * .95 = [ 204.00 + 50.00 + 1.25 ] * 1.00 * .95 = [255.25] * 1.00 * .95 = 242.49 The nice thing about EZBREW is that you don't have to understand any of the math in order to use the °Extract principle to assist you in brewing quality beers! Let all of the mathematical "mumbo-jumbo" for me to worry about, and just enjoy using the program (and tasting the results)! Back to where we left off before the "Jim takes a trip to Mathematics Land" side track! Answering "Yes" to the "OKAY" box will result in EZBREW asking you for the length (in gallons) of the wort. Enter the number of gallons you actually have in the boiling kettle, NOT the final length you will be making. This is critical for a whole lot of reasons, but particularly when it comes time to figure out the amount of Hops you will use! For example, if your boiling kettle will only hold 2.5 gallons, use 2.5 as your value. In my case, my kettle will hold all 5.0 gallons we're making, so I entered 5. But make sure that you use the number of gallons actually in the kettle. Otherwise when you calculate the amount of Hops to use to get a desired level of bitterness, you will be in error and your brew won't taste like you thought it would. ________________________________________________________________________________ Page 34 After entering the length of your batch, you will see a screen similar to the following: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Using Degrees of Extract to Develop a Brew ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ You have chosen these ingredients for your brew: ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ Ingredient °Extract Grain ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ═════════════════════════════════════════════════════════ ║ │ GLOSSARY ▄ │ ║ Jim's Special Beer Honey 48.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Pale Malt 34.00 6.00 ║ │ MATH ▄ │ ║ Crystal Malt 25.00 2.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Black Patent Malt 5.00 0.25 ║ │ TABLES ▄ │ ║ ═════════════════════════════════════════════════════════ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Total Extract = 242.49 ║ │ UTILITIES ▄ │ ║ Length (Gallons) = 5.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Est.

A lot of reasoning beyond the scope of this user's guide has gone into determining this value, but suffice it to say that it is a good "rule of tongue" to use if "REAL BEER" taste and "mouth feel" is important to you (if not, why are you brewing at home?). After activating the "< OK >", you will be given the chance to enter the percentage of the brews Total °Extract that you wish to be derived from GRAINS (including grain extracts, etc.). Pressing [┘ Enter] at this point will use the 80% figure, so if you want to stick to the "rule of tongue" of 80%, just press [┘ Enter] without supplying a value (Note: The EZBREW supplied value is called a "default" value - if you don't choose to enter anything, you will use the value that is "set" into the program by default.) If you wish to use a value other than the 80% default, enter it at this time. You all grain brewers out there would enter 100, since you would never think of using sugars of any kind in your "He-man Brews"! Now that EZBREW knows the specific GRAINS/EXTRACTS you are going to use, and the Total °Extract you will be deriving from them, it's time to repeat the process for any and all SUGARS that you might be using (see the next page for our example). Note here that the "units" you will be using are specified by EZBREW (in the "OKAY" Box) to be "pounds", so provide input in these terms. This step is NOT used if you are being "macho" and brewing an ALL GRAIN BEER (my hat's off to all of you out there who brew ALL GRAIN BEERS!), where no SUGARS are ever used! EZBREW will recognize this SPECIAL case and skip over this SUGAR stuff for you, so you won't even see it appear! Once you have the GRAINS/EXTRACTS set up the way you want them, it's time to get on to the SUGARS... ________________________________________________________________________________ Page 35 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Using Degrees of Extract to Develop a Brew ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ You have chosen these ingredients for your brew: ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ Ingredient °Extract Grain ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ═════════════════════════════════════════════════════════ ║ │ GLOSSARY ▄ │ ║ Jim's Special Beer Honey 48.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Pale Malt 34.00 6.00 ║ │ MATH ▄ │ ║ Crystal Malt 25.00 2.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Black Patent Malt 5.00 0.25 ║ │ TABLES ▄ │ ║ ═════════════════════════════════════════════════════════ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Total Extract = 242.49 ║ │ UTILITIES ▄ │ ║ Length (Gallons) = 5.00 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Est.

In our example it shows up as 60.62 °Extract (see next page). "How can this be?", you ask. "I haven't even entered anything yet!" Simply put, EZBREW is telling you at this point that if you want to get a certain percentage of your brew's Total °Extract from the GRAINS/EXTRACTS you have chosen, this is the °Extract you should shoot for from SUGARS only. In our case, since we want 80% of the brew's Total °Extract to come from GRAINS/EXTRACTS, 20% must come from the SUGARS. The 60.62 value shown by EZBREW represents 20% of the brew's total, based on the °Extract from all of the GRAINS/EXTRACTS that you are using. Thus, in order to get 20% from the SUGARS, you should use enough SUGARS to get 60.62 °Extract. Remember, you don't have to understand the math involved, just how to use EZBREW and what all of the numbers on the screen mean. So if you are not inclined towards math, just learn to interpret the values that EZBREW calculates. If you have but one source of SUGAR, figuring out how much to use is easy. Simply divide the value reported in EZBREW by the °Extract of the SUGAR to get the number of pounds of the SUGAR to use. For our example, this means: Total °Ext.

After deciding to keep things as they are (for example purposes), EZBREW will next ask you for the number of gallons after boiling. This permits you some loss in the boiling process, but if you don't have any (you added water as you went along to keep things at the same level), enter the original length and press [┘ Enter].

This is the place to make that adjustment. If you choose to adjust (answer "< Yes >"), two options are available. You can either change the length of the batch, and as a result watch the gravity change, or you can tell EZBREW that you want a certain gravity, and EZBREW will tell you the length you need to get it! In our example, you were shooting for an Initial Gravity of 1.048, and EZBREW has calculated that the Initial Gravity of the brew will be near 1.063, so adjustment is necessary. This is done by selecting "< Yes >" to the "Adjustment Question", and choosing "<S.G.>" from the Choice Box that appears.

First, the bottom left hand corner of the Action Window contains a "live" estimate of the alcohol content of your brew if it were to have a Final Gravity at the "quarter gravity" level. This is the level that a lot of GRAIN brews will "settle down" to when fermentation is complete. Notable exceptions are the dark beers, like stouts, porters, etc., who's Final Gravity will be somewhat higher than the quarter gravity level. If you are using ALL GRAINS, or very little SUGARS, the "quarter gravity" value will be pretty close to what you should end up with. This value may be somewhat misleading as you are developing the list of ingredients, but as you near the completion of the list, it will serve as an initial "best guess" indicator of the potential strength of your finished brew. Still, until you actually measure the Final Gravity, I would use it as an "educated guess" only! The second thing is the moving "" that goes back and forth along the bottom right hand portion of the Action Window. The "Ziggle" as I call it is an indication that EZBREW is finished doing whatever you told it to do, and that you need only press a key (or RIGHT click) to return to the °EXTRACT Side-Menu. It is also a WARNING that you are about to erase the screen and loose all of your work, so if you want a copy of what you have done, press and hold either [SHIFT] key, and at the same time press [PRINT SCREEN] ([PRNT SCRN]). Of course, before you do this you should make sure that your printer is connected to the printer port on your PC, it's turned on, and the paper is in it and at the top of the page. You should also set the printer to print in "Graphics" mode, so that all of the lines, boxes, etc. come out correct. Well, that about wraps up the °EXTRACT Program option. Try it a few times to get the hang of it. Experiment with some published recipes, or try your own. I hope that you too find it a little better than pencil and paper! ________________________________________________________________________________ Page 40 α- ACIDS ──────── Beer tastes the way that it does in part due to the balance achieved between the sweetness derived from the malts and the bitterness that we all know comes from the Hops used in the brewing process. The "alpha acids" (α-Acids) in the Hops, brought out through boiling the Hops in the wort for up to 90 minutes, are the primary agent for the bitterness that we taste. We also know that for a given variety of Hops (such as Saaz, Willamette, etc.), the amount of these α-Acids not only varies from year to year, but also from one "Hop farm" to another, even within the same geographic region. Because of the variability that we find in the "bittering potential" of Hops, we need to develop a systematic method for determining the amount of Hops to use in a brew in order to arrive at some predictable and repeatable level of bitterness in the finished product. Without such a system, the bitterness of our brews would vary considerably, making it difficult, if not impossible, to plan a batch, much less recreate a batch that was especially good with any hope at all. α-Acid levels for Hops are commonly measured by the producers/sellers and reported in "Alpha Acid Units" (AAU's). In particular, AAU's simply represent the percent of the total weight of a sample of Hops that is composed of α-Acids. For example, for a given amount of Hops with an AAU of 5.0, 5% of the total amount (weight) is actually the α-Acid portion. Similarly, an AAU of 13.2 means that 13.2% of the weight of the Hops is the α-Acid fraction, and so on. This not only makes it easy to understand what AAU is, but makes comparisons between Hops varieties simple (in terms of bitterness - not all Hops smell the same). Most producers/sellers will indicate the AAU level somewhere on the package that the Hops come in, but it does not hurt to ask for the information when you place your order for your supply of Hops. You have to have this data in order to brew consistently good batches, and that's what you are trying to do, right? The first step in planning your brew is your choice of ingredients (the fermentables particularly). Once accomplished, you will have some indication of the initial specific gravity of the boiling wort, a bit of information you need to have in order to effectively plan the addition of your Hops. Armed with the AAU levels of the varieties of Hops you plan to use, you can then activate the "α- Acids" Side-Menu option, and begin to calculate the amount of Hops you will be using to achieve a desired level of bitterness and aroma that YOU want. EZBREW actually permits you to use one of two methods to calculate the amount of Hops you should use to bitter the beer to your desired level. The first is referred to as "International Bittering Units" (IBU's), while the second is called "Homebrew Bittering Units" (HBU's). Without going into detail, IBU's are calculated the same way that HBU's are, except that they take into account not only the AAU level of the Hops used, but also the length of time that the Hops are boiled, and the initial specific gravity of the boiling wort. The longer the Hops are boiled, and/or the "thinner" the wort is at the boil (lower specific gravities), the higher the utilization rate for extracting the α-Acids will be (all other things being equal). IBU's thus provide a much more refined estimate of the final bitterness of the brew, and since you don't have to worry about the math, IBU is the recommended method to use. If you are interested in learning more about Hops and bitterness, the article by Jackie Rager (IBU) (in fact the whole "Hops" special issue of zymurgy magazine that Jackie's article is in) and the book by Dave Line (HBU) should give you "all of the answers". Simply activate the "Help!" item on the "α- Acids" Sub-Menu for more complete information. Upon entering the α-Acids option, you will be asked which of the methods you wish to use to deal with the bitterness question: ________________________________________________________________________________ Page 41 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ α-Acid Calculation ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌──────────────┐ ║ │ REFERENCES ▄ │ ║ │ Method? │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════╡██ ║ │ GLOSSARY ▄ │ ║ │░░░░░IBU░░░░░░│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ HBU │██ ║ │ MATH ▄ │ ║ │ Help! │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ ════════════ │██ ║ │ TABLES ▄ │ ║ │ Exit to Main │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ └──────────────┘██ ║ │ UTILITIES ▄ │ ║ ████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ HELP! ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Activate "Help! to find out more about IBU and HBU! ║ │ EXIT ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ └───────────────┘ ║ ║ ║ ║ ║ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ α-Acid Calculation, IBU Approach ──────────────────────────────── Selecting "IBU" requires you to know (in addition to the specific gravity of the boiling wort) the amount of each variety of Hops you plan to use, as well as the length of time you will be boiling each, and will result in a calculation of the ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ α-Acid Calculation, IBU Approach ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ╔══════════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Calculate what? ║ ║ │ GLOSSARY ▄ │ ║ ║ ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╟──────────────────────────╢██ ║ │ MATH ▄ │ ║ ║ < IBU > < Hops > ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╚══════════════════════════╝██ ║ │ TABLES ▄ │ ║ ████████████████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ UTILITIES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ HELP! ▄ │ ║ If you know the amount of each variety of Hops you are ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ using and want to find out the final level of bitterness ║ │ EXIT ▄ │ ║ your brew will have, select "IBU".

You decide that you want it to turn out as a "Pale Ale", and, skipping ahead in your tour of EZBREW, you go to the TABLES Side-Menu option and activate "IBU by Type": ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ IBU Range by Beer Type ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ╒═══════════════════════════════════╕ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Type IBU Range │ ║ │ REFERENCES ▄ │ ║ ╞═══════════════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Ale, Brown 31.0 - 38.0 ██ ║ │ GLOSSARY ▄ │ ║ │ Cream 20.0 - 70.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Mild 31.0 - 38.0 ▓██ ║ │ MATH ▄ │ ║ │▓▓▓▓▓▓Pale▓▓▓▓▓▓▓▓▓▓▓▓19.0 - 54.0▓░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ India Pale 11.2 - 24.0 ░██ ║ │ TABLES ▄ │ ║ │ Alt 21.0 - 31.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Barley Wine 32.0 - 100.0 ░██ ║ │ UTILITIES ▄ │ ║ │ Bitter 23.0 - 44.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Bock 26.0 - 35.0 ░██ ║ │ HELP! ▄ │ ║ │ Dopplebock 28.0 - 40.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Dortmunder 18.0 - 26.0 ░██ ║ │ EXIT ▄ │ ║ │ Kölsch 21.0 - 31.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Lager, American Lite 7.0 - 19.5 ░██ ║ └───────────────┘ ║ │ Am.

Great! You decide that you will boil the wort for a total of 1 hour. Let's also say that you want to use Willamette Hops (AAU 5.0) for the boiling variety, and decide to use 1 ounce at the beginning of the boil, while you will add 1/2 ounce 30 minutes into the boil. You also choose to reserve your best Saaz Hops (AAU 4.9) for the aroma component, and you will be adding it during the last 2 minutes of the boil. After using the °EXTRACT Side-Menu option to determine your ingredients and finding out that the estimated specific gravity of the 5 gallons of boiling wort will be near 1.063 (our example), you have the information you need to go on. Activate the α-ACIDS Side-Menu option and select "IBU". You are then asked to enter the number of additions of hops you will be using in your brew (see the next page). Note here that we are NOT talking about the actual varieties, how much we are using, or when they will be added. EZBREW simply wants to know how many times you will be adding Hops to the wort. In the "MIDNIGHT ALE" example we are working with, recall that you will be adding Willamette Hops at the beginning of the boil and again 30 minutes into the boil (2 ADDITIONS of a single variety), and then all of the Saaz (the second variety of Hops you are using) will be added so that it boils for only 2 minutes. This results in a total of 3 ADDITIONS to your brew, so select "3" from the list, and you are given a list of Hops varieties to choose from: ________________________________________________________________________________ Page 43 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ α-Acid Calculation, IBU Approach ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ┌────────────────────┐ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Additions of Hops? │ ║ │ GLOSSARY ▄ │ ║ ╞════════════════════╡ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 1 │██ ║ │ MATH ▄ │ ║ │ 2 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │▓▓▓▓▓▓▓▓▓3▓▓▓▓▓▓▓▓▓▓│██ ║ │ TABLES ▄ │ ║ │ 4 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 5 │██ ║ │ UTILITIES ▄ │ ║ │ 6 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 7 │██ ║ │ HELP! ▄ │ ║ │ 8 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 9 │██ ║ │ EXIT ▄ │ ║ │ 10 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ └────────────────────┘██ ║ └───────────────┘ ║ ██████████████████████ ║ ║ ║ ║ In our example, select "3" additions of Hops! ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ α-Acid Calculation, IBU Approach ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ┌────────────────────────┐ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Varieties │ ║ │ REFERENCES ▄ │ ║ ╞════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Pride of Ringwood 8.5 ██ ║ │ GLOSSARY ▄ │ ║ │ Progress 5.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Saaz 4.9 ░██ ║ │ MATH ▄ │ ║ │ Saaz 4.9 ░██ Select 3 varieties ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │Saaz 4.9 ░██ of hops to use. ║ │ TABLES ▄ │ ║ │ Saaz 4.5 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Spalt 4.5 ░██ ║ │ UTILITIES ▄ │ ║ │ Styrian Gold 6.5 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Tallisman 7.0 ░██ If you want to use a ║ │ HELP! ▄ │ ║ │ Tettnanger 6.0 ░██ specific variety more ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │Willamette 5.0 ▓██ than once, it has to ║ │ EXIT ▄ │ ║ │Willamette▓▓▓▓▓▓▓▓▓5.0▓██ appear in the Tag Menu ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ├────────────────────────┤██ list once for each time ║ └───────────────┘ ║ │ < OK > │██ you want to use it! ║ ║ └────────────────────────┘██ ║ ║ ██████████████████████████ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ Now you must select the specific varieties/AAU's that you will add.

The Saaz addition will be boiled for the final 2 minutes of the total 60 minute wort boiling, so enter 2.0 as your value. For the Willamette Hops, the 0.5 ounce addition is made 30 minutes into the overall boil, so: 60 (total wort boil) - 30 (until addition) = 30 minutes of boiling The 1 ounce addition is made at the beginning of the 60 minute wort boil, so it boils for the full 60 minutes. Make sure varieties/AAU's and boil times match! As you make your entries, you will probably notice the "Util" column appear, and decimal values suddenly pop up after you press [┘ Enter]. This column contains "utilization efficiency" values for the extraction of the α-Acids in the Hops, and is based on the length of time that you boil each addition. The maximum that home brewers can expect to achieve is somewhere around 30% (0.30)! This is one example of how the IBU approach is more complete than the HBU method, as the "extraction efficiencies" do play a role in determining the level of bitterness that you will achieve in your brew. You may have noticed the term "Dry Hopped" in the note. Keep in mind that the purpose of this section of EZBREW is to calculate bitterness, and not aroma. Dry Hopping (the addition of dry Hops to the primary fermenter after sparging) contributes virtually nothing to bitterness, and is a technique used to enhance the aroma component of brews. Thus, if you choose "Dry Hop" (essentially the same as a "0" minute boil), the utilization efficiency column will show "0", indicating that this addition does not contribute to the bitterness of your brew. ________________________________________________________________________________ Page 46 After all the values are entered, your screen should look something like this: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ α-Acid Calculation, IBU Approach ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ Variety AAU oz.

For our example, the MIDNIGHT ALE we are making would turn out to have 28.10 IBU's, which is nicely within the "Pale Ale" IBU range seen earlier. Notice the last column in the table ("IBU")? It's a breakdown of just where the 28.10 IBU's came from by ADDITION! This information can be quite useful to you as the following will illustrate. Suppose that you don't want 28+ IBU's in your brew, and would rather be closer to the lower recommended limit (19 IBU's) for Pale Ales. What could you do to get closer to that value? At least two possibilities exist - cut back on the amount of Hops you are using, and/or reduce the boiling times for an addition somewhat. The entries in the following table are left for you to verify as a practice session of the α- ACIDS Side-Menu option, and clearly indicate just what you can easily do using EZBREW!

Satisfied? α-Acid Calculation, HBU Approach ──────────────────────────────── If you made it through the IBU section, you will have no difficulty using HBU. This approach is included in EZBREW because at the time this is being written, there are still a lot of recipes that contain HBU's, and a lot of brewers are familiar with it's use. Rather than explain this approach in detail, only items needing definition will be discussed. Perhaps first on the list is the basic concept of what an HBU is. If you take the AAU level for a Hops, multiply it by the number of ounces of that Hop you are going to use, and divide by the length (gallons) of the batch, you get HBU's. For example, suppose you are going to use 2 ounces of the Willamette(5.0) Hop in a 6 gallon batch. Using the formula: 5.0 AAU's * 2.0 ounces / 6 gallons = 1.67 HBU's So in reality, an HBU is simply the amount of α-Acids/gallon of wort, multiplied by 100 to scale the values into a meaningful range (the 1.67 HBU above is the same as 0.0167 ounces of α-Acid/gallon of wort). In the "MIDNIGHT ALE" example you went through for the IBU method, you would follow this procedure for each Hop, and then add the results: ________________________________________________________________________________ Page 51 Calculating the HBU's for our "MIDNIGHT ALE": ───────────────────────────────────────────── ( 2 min) 4.9 AAU's * 0.5 ounces / 5 gallons = 0.49 HBU's (Saaz) (30 min) 5.0 AAU's * 0.5 ounces / 5 gallons = 0.50 HBU's (Willamette) (60 min) 5.0 AAU's * 1.0 ounce / 5 gallons = 1.00 HBU (Willamette) ───── Total for the batch: 1.99 HBU's (0.0199 oz/gal) The values on the left side of the page are to remind you about the boil times for each Hop used. Notice that boiling times don't have any influence on the projected bitterness derived from a Hop, which is quite a bit different than in the IBU approach. According to the HBU method, this means that an ounce added at the beginning of the boil contributes the same bitterness as an ounce of the same Hop variety added with only 2 minutes to go! I don't know about you, but I find this hard to take. Second, the gravity of the wort does not figure in anywhere, and finally, the bitterness scale is drastically reduced (28.10 IBU's is now represented by 1.99 HBU's!), which adds a lot of confusion to things. Operationally, HBU is similar to IBU, except for the opening HBU screen: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ α-Acid Calculation, HBU Approach ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Size (Gallons): 5 ──┬────── Batch HBU's: 3░░░ ║ │ REFERENCES ▄ │ ║ │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ ╔════════════════════════╗ ║ │ GLOSSARY ▄ │ ║ Use the [TAB] key or │ ║ Suggested HBU Levels: ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ [┘ Enter] to jump │ ╠════════════════════════╣█ ║ │ MATH ▄ │ ║ between fields. ─┘ ║ Lagers 1.5 - 2.0 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Ales Mild 2.0 - 2.5 ║█ ║ │ TABLES ▄ │ ║ Press [ESC] or click ║ Light 2.0 - 3.0 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ the LEFT mouse button ║ Brown 2.0 - 3.0 ║█ ║ │ UTILITIES ▄ │ ║ to record your inputs ║ Pale 3.0 - 5.0 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ and continue. ║ Bitters 2.5 - 3.5 ║█ ║ │ HELP! ▄ │ ║ ║ Stouts Sweet 2.5 - 3.5 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Dry 3.5 - 5.0 ║█ ║ │ EXIT ▄ │ ║ ╚════════════════════════╝█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ └───────────────┘ ║ ║ ║ ║ ║ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ In this case, you enter either the length (in gallons), the desired level of bitterness (HBU), or both.

It should! Functionally it's designed to operate in a fashion similar to the IBU method that was just described, so you should have no trouble with it. In fact, a lot of what you see throughout EZBREW will appear familiar - so much the better for you to learn how to use the program. But you do need to be careful. In the IBU approach, when entering Hops, you were concerned with "additions" since the time that a particular amount of Hops was boiled determined the "utilization efficiency" of the α-Acids present in the Hops. The only difference here is that you will be picking varieties to add, NOT additions to be made, since the boiling times are not included anywhere in the HBU calculation. But if you read the notes that appear in the Action Window as you travel through the program (what I call situational help) and pay attention to menu titles, you should be OKAY. After choosing the varieties of Hops you want to use, EZBREW will request additional information from you, depending on the entries you made on the first screen. It may ask you for the amount of each variety of Hops you want to use, or to enter the percent of total HBU that should come from each variety, etc. Simply provide the data as it's requested, and you will end up with a summary like you see on the following page.

Of course, before you do this you should make sure that your printer is connected to the printer port on your PC, it's turned on, and the paper is in it and at the top of the page. You should also set the printer to print in "Graphics" mode, so that all of the lines, boxes, etc. come out correct. I would recommend that you examine the relative merits of each of the methods presented in EZBREW, and choose the one that you think meets your individual brewing needs. Both methods have advantages, and in certain circumstances, both are applicable to recipes you may be working on. In addition, if you are given a recipe expressed in terms of HBU, you can convert it to IBU, or visa versa. Another example of the broad base from which EZBREW can operate. Well, that about wraps it up for α-Acid and bitterness calculations. Remember though, that even the best program can't take the place of care in selecting, storing, and using Hops. But if you deal with reputable dealers, keep your hops frozen and out of the light, and insist on "oxygen barrier" bags, you have already gone a long way at preserving the fresh hop bite and wonderful aroma that you seek. ________________________________________________________________________________ Page 54 REFERENCES ────────── This Side Menu option is used to look up sources of information that you might like to obtain or borrow from a friend or your local library if you have a brewing related question, and can be thought of as being a list of "experts" that might be able to give you an answer.

There may be some arrows and a shaded "Position Bar" along the right side of the box, indicating that there are additional items available that you can't see. In order to see them, use the [UP], [DOWN], [PAGE UP], [PAGE DOWN], [HOME], or [END] cursor keys, or click with the LEFT mouse button on either of the arrows to move the selection bar from item to item. You can also "drag" the indicator on the Position Bar by clicking the LEFT mouse button while the mouse cursor is anywhere in the Position Bar (except on the indicator of course). You will see the indicator moving up and down the bar, showing you are in the list - near the top of the bar indicates that you are near the beginning of the list of items, while the bottom of the bar means you are close to the end of the list.

Press [ESC] or click on the small square in the upper left corner of the definition window with the LEFT mouse button to get out, and you will return to the GLOSSARY menu you just left. As with the REFERENCES Side-Menu option, there is no way to modify this list unless you have an ASCII text editor, and want to mess around in the file "EZBREW.GLS" a bit. Once you see how the file is structured (you can print it if you want, but it is quite big), you can modify the contents as you see fit. This is perhaps one addition to a future release of the registered version of EZBREW that I will make if the demand for such a capability is high enough. ________________________________________________________________________________ Page 57 MATH ──── MATH? Don't get too worked up just yet, because EZBREW will take most of the pain out of the math you will need to do in order to make that awesome batch of your favorite brew. All you need to worry about is deciding what you need to do, provide some input, and let EZBREW muddle through all of the "ciphering" for you. The MATH option of EZBREW is where all of the calculations and conversions are performed that are independent of other functions in EZBREW. In fact, as you become more and more familiar with the program, you will notice that some of the MATH options you find here will show up at other places as part of things you will be doing in other program options. But for now, we will restrict the discussion to the items found in the MATH Side-Menu option. Activating the MATH Side-Menu option from the Main Menu level of EZBREW will produce the following screen: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Calculations & Conversions ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌───────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Option? │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞═══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │▓▓▓▓%Wt <-> %Vol▓▓│██── Selection ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ °C <-> °F │██ Bar ║ │ MATH ▄ │ ║ │ Potential Alcohol │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ S.G.

So, for example, if you want to find out what math is involved in "Keg Carbonation", activate the "Help!" item (NOT the "Keg Carbonation" item), and scroll down through the help information until you come across the stuff on keg carbonation. There you will find a description of what's going on, and you can decide whether or not you want to continue on with things. Couldn't be any easier. ________________________________________________________________________________ Page 58 Converting Alcohol Content Between % by Volume and % by Weight. ─────────────────────────────────────────────────────────────── The first item on the MATH Sub-Menu, "%Wt <-> %Vol" is used if you are given the alcohol content in one measurement system, and wish to know what it is in another system. For example, suppose your friend says that his brew contains 5.6% alcohol by Volume, and you want to find out how it compares to your brews that normally end up around 3% Alcohol by weight. Activating the "%Wt <-> %Vol" item, you will be asked to provide a value to be converted. But before you go to far, notice the "NOTE" at the bottom of the Action Window. It tells you that your value is assumed to have been taken for a brew at 25° Centigrade (how would you convert that to Fahrenheit, I wonder?), and for a mixture of alcohol and water only. What it's saying is that if this is not the case, your conversions are going to be a little off of reality, so try to match the conditions of the note as closely as possible. A little "error" is to be expected, however, because your brew is not just alcohol and water. But the results of the conversion will be close enough. Let's convert your friend's % by Volume to % by Weight. Type in the "5.6" (without the quote marks of course) and press [┘ Enter]... ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ % Alcohol by Weight to/from % Alcohol by Volume. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ Values Must be Greater than 0. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ REFERENCES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Enter the value to be converted: 5.60% ║ │ GLOSSARY ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ MATH ▄ │ ║ ╔══════════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Yet another ║ Is the above value % by: ║ ║ │ TABLES ▄ │ ║ "Choice Box" ║ ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ for you to ╟──────────────────────────╢██ ║ │ UTILITIES ▄ │ ║ use. ║ < Volume> < Weight > ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╚══════════════════════════╝██ ║ │ HELP! ▄ │ ║ ████████████████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ EXIT ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╔════════════════════════════════════════════════╗ ║ └───────────────┘ ║ ║ Values are assumed to be at 25° C (77° F), and ║█ ║ ║ ║ are based on a mix of ethanol and water only. ║█ ║ ║ ╚════════════════════════════════════════════════╝█ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ EZBREW now needs to know whether the value entered was in % by Volume or % by Weight.

And all you had to do was type in a few numbers! Click on the "< OK >" to exit this function and return to the HELP! Sub-Menu (could you press [ESC] or use the RIGHT mouse button, or [O] or [o]?). Converting Temperature Readings. ──────────────────────────────── Temperatures are normally given in Centigrade or Fahrenheit units. The problem is that some recipes call for one, some the other, and some give both. What do you do if the recipe you're using lists all temperatures in units that you are unfamiliar with, or worse yet, mixes units? Suppose for example that your recipe instructs you to add some 76.7° Centigrade water to your brew. The problem is that you don't have a thermometer that reads in Centigrade, and you can't remember that pesky conversion formula - so what do you do? Use EZBREW of course! Activate the "°C <-> °F" from the MATH Sub-Menu, and enter the value of "76.7" (not the quote marks of course). Before you go on, did you notice that EZBREW told you that the values you provide had to be between -999.9 and 999.9 degrees? Input data limits appear throughout the program, and if you attempt to use values outside of the range given, results may not be what you expect! When asked for information in this fashion, you can ABORT and exit from the program function by pressing [ESC] or [┘ Enter] without providing a value (called a "blank return"). Thus, in the above example, when asked to "Enter the value to be converted:", simply press [┘ Enter] before you type any values, or [BACKSPACE] over the values until they are all gone and then press [┘ Enter], and you return to the MATH Menu. ________________________________________________________________________________ Page 60 After you have entered the "76.7" value, EZBREW will next ask you if this a Fahrenheit or Centigrade temperature. Click on your choice (or type the "hot" letter) and EZBREW will give you the answer (in our example, click on the "Centigrade" or type [C] or [c]). These "choice boxes" will not permit you to use the cursor keys, so the mouse and "hot" letters are all that remain. ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Conversions between Centigrade & Fahrenheit Units. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ GLOSSARY ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ MATH ▄ │ ║ ╔═════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ 76.7° C = 170.06° F ║ ║ │ TABLES ▄ │ ║ ║ ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╟─────────────────────╢██ ║ │ UTILITIES ▄ │ ║ ║ < OK > ║██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╚═════════════════════╝██ ║ │ HELP! ▄ │ ║ ███████████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ EXIT ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ Yes, it's your old friend the "OKAY" Box! ║ └───────────────┘ ║ ║ ║ ║ ║ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ This puts you at the old "OKAY Box".

Pressing [ESC], [O] or [o] (the letter, not the number), [┘ Enter], or clicking on the "< OK >" with the LEFT mouse button will return you to the MATH Sub-Menu (as will [ESC] of course). Calculating Potential Alcohol. ────────────────────────────── At some point or another, you will want to estimate the potential alcohol content of the brew you are working on. This requires two things - the specific gravity of the wort at the beginning of primary fermentation (just prior to adding the yeast), and the "gravity" at the end of the secondary fermentation, or just before you bottle/keg the stuff. For example. Suppose that you are brewing that ultimate "MIDNIGHT ALE" you are developing, and you are just about to keg it. But first, you realize that it might be a good idea to figure out the potential alcohol content so that you might be able to adjust it if necessary (you don't want to wipe out your friends with a batch of "Barley Wine", do you?). So you go back to your beer log, and note the following: Initial S.G.: 1.052 @ 105° F Final S.G.: 1.029 @ 60° F ________________________________________________________________________________ Page 61 With this information in hand, select the "Potential Alcohol" item from the MATH Sub-Menu. You will be asked to enter the Initial and Final Gravities, and then to identify whether they are in Specific Gravity or "Brix" units. Don't be concerned at this point if you don't know what "Brix" is - you can find out later using the GLOSSARY option from the Side Menu!

That means that you could share it with just about anybody and not worry about "single bottle headaches" taking place. It also means that you now know how use EZBREW to determine the potential alcohol content, and it was easy to learn, right? Notice that you have calculated POTENTIAL alcohol content of your brew, and even though this value is probably very close to the ACTUAL content, it would take more sophisticated methods to arrive at the true figure. But the value reported by EZBREW is very close. Also notice that EZBREW tells you to "Enter values corrected to calibration temperature." This means that you need to make sure that the gravity readings you enter were made at a wort temperature that is the same as the hydrometer calibration temperature. This leads into the next section (clever how I bridged the gap, yes?)... Correcting the Hydrometer Reading. ────────────────────────────────── In the previous example, you recorded two "gravity" readings for your "MIDNIGHT ALE", and you learned how to use that information to calculate the potential alcohol content of your brew. But you measured the Initial Gravity when the wort was at 105° F (40° C), and made the Final Gravity reading at 60° F (about 15.5° C). Does this make a difference in the potential alcohol calculation? Think about it. We know that as water and alcohol change temperature, they shrink and swell, taking up different volumes at different temperatures. The problem is that the rate at which alcohol does this is different than the rate for water, which messes things up for us when we have both in one solution. In order to get around this problem, most hydrometers have been "calibrated" to give an accurate gravity reading only at a well defined wort temperature, usually 60° F (15.5° C). This means that if your specific gravity measurements are made at some other temperature, the readings you get will be slightly in error. So what can be done? EZBREW to the rescue, naturally! The "S.G. Corrections" item in the MATH Sub-Menu gives you the capability of making corrections to specific gravity readings for worts at temperatures between 50 and 105° F (10 and 40° C), when using a hydrometer calibrated at 60° F (15.5° C). If you don't know the calibration temperature for your hydrometer, check the paperwork that came with it. If the calibration temperature is not 60° F, you will have to use the UTILITIES Option from the Side Menu to enter the specifics for your own hydrometer (see the UTILITIES Program Option section of this manual). Let's look at the "MIDNIGHT ALE" example that you just went through. You calculated a potential alcohol content of about 3% by Volume. But this did not take into account the fact that the Initial Gravity reading was taken at a high wort temperature (105° F), well above the calibration temperature of the hydrometer. In order to compensate for this, activate the "S.G. Corrections" item, and enter the value you measured for the Initial Gravity, and the temperature at which it was made (see how important good notes are).

This all goes to show how the various components of EZBREW can be linked together to attack a lot of the fundamental problems facing home brewers. The more you use EZBREW, the more you will see that can be combined. When will the brew be ready? ──────────────────────────── After you have boiled the wort, the fermentation is finished, and you have put up your brew in bottles or a keg, you might ask "So when will this stuff be ready to sample?" Although I know of no really accurate way to tell short of "popping one" every week or so, EZBREW does have the capability to help you decide. You will find it in the "Flavor Peak" item on the MATH Sub-Menu. The technique employed by EZBREW to determine the flavor peak is based on the work of B. C. A. Turner and D. J. Moon, who authored the book "Simple Guide to Home Made Beer" in 1968. You will find that information displayed in the Action Window while you're performing the "Flavor Peak" calculation. The Turner/Moon method is based on the initial specific gravity reading of the batch. Again, turning to your "MIDNIGHT ALE" concoction, the CORRECTED initial gravity was 1.059. Enter this value into EZBREW (note the input limits): ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Flavor Peak Estimation ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ REFERENCES ▄ │ ║ Enter the Initial Hydrometer Reading: 1.059 ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ GLOSSARY ▄ │ ║ (Must be between 1.020 & 1.100, [5° & 25° Brix]) ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ MATH ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ TABLES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ UTILITIES ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ HELP! ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╔════════════════════════════════════════════════════╗ ║ │ EXIT ▄ │ ║ ║ Based on the work of: ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ B.

(Fat chance, you say?) Most recipes I have read recommend a minimum of 2 weeks in the bottle/keg to permit all of the flavors to "settle down" and mix well. They say that "drinkability" is greatly improved if the 2 week "aging" period takes place. And so, from a practical point of view, this might be considered a "minimum waiting period", but of course you are free to sample your work before then, and find out for yourself if it's true! This brings up another point. Good notes in a log of some sort are a must for serious home brewers. In this case, aging times and temperatures that produced the "best" flavors should be noted, so that when you repeat the recipe (in original or slightly modified form), you will have a better handle on what to expect, and can plan your "shin-dig" for the ultimate flavor. You could also use the notes to plan the brewing of several batches so that they were all at "peak flavor" at the same time, and really impress your friends with a selection of premium home brews at one party! ________________________________________________________________________________ Page 66 Keg Carbonation. ──────────────── So you are tired of cleaning all of those bottles, and have "graduated" to using a keg? Great! But if you also choose to artificially carbonate your keg with bottled CO2, you will need the "Keg Carbonation" item in the MATH Sub-Menu to help you figure out how much CO2 to use to get the carbonation levels you want. As with several other functions in EZBREW, this capability is based on the work of an "expert, in this case an article by Byron Burch I found in the Fall 1990 issue of "The Beverage People Newsletter" (Look under "Beverage People" in the REFERENCE main program option of EZBREW). I highly recommend that you read the article to learn a lot about using kegs that I won't go into here. Okay, so you have your keg hooked up like Byron Burch tells you to, and you know that it is at 60° F. Since your "MIDNIGHT ALE" is being brewed like a British style beer, you decide to carbonate it to a level similar to contemporary British Ales. Select the "Keg Carbonation" item, and you will see a screen like: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Carbonating Keg Beer with Bottled CO2 ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╔════════════════════════════════════╗ ║ │ REFERENCES ▄ │ ║ ║ Suggested CO2 Volumes: ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╠════════════════════════════════════╣█ ║ │ GLOSSARY ▄ │ ║ ║ British Style Beers - 1.00 to 2.40 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Most Other Beers - 2.40 to 2.85 ║█ ║ │ MATH ▄ │ ║ ║ Highly Carbonated - 2.85 to 2.95 ║█ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╚════════════════════════════════════╝█ ║ │ TABLES ▄ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ UTILITIES ▄ │ ║ Input the volume of CO2 desired: 2.3░ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ (Values between 1.00 and 4.00) ║ │ HELP! ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ EXIT ▄ │ ║ ╔══════════════════════════════════════════════════════╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ Based on: The Beverage People News, Fall 1990 Issue ║█ ║ └───────────────┘ ║ ║ Published by: The Beverage People, 840 Piner Rd. #14 ║█ ║ ║ ║ Santa Rosa, CA 95403 (707) 544-2520 ║█ ║ ║ ╚══════════════════════════════════════════════════════╝█ ║ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ In this case, you enter 2.3 for the volume of CO2 to use, since the suggestions indicate that British Style Beers should have a CO2 volume somewhere between 2.0 and 2.4, and since you have no other reason for doing so, you pick 2.3 as "it". Don't worry to much about "what is a volume of CO2?", as I really don't understand it myself, and thus I can't explain it, except to note that the more "volumes" you put into your brew, the "fizzier" it will be. In fact, Rande Reed in his article "English Ales: The tradition of Brewing, Handling, and Serving." in the 1985 Special Issue of zymurgy magazine, says that for a draft, 5-gallon batch, he uses only two (2) ounces of priming sugar (which adds 0.8 volumes of CO2, according to Terry Foster in: PALE ALES, Classic Beer Style Series #1) After providing the volume of CO2, you will be asked for the temperature of the batch in the keg. In our example, it's 60° F.

The carbonation procedure can be found in the article by Byron Burch, so I won't go into it here. Of course, as you gain experience, you will become better able to gauge these values. For example, real British ales are served at "cellar temperature", and are very lightly carbonated (maximum of about 1.0 volume of CO2). American "malt beverage" (I refuse to call what is sold in the United States "beer" for fear of defaming the good name associated with the great beers of the world) on the other hand, is carbonated at markedly higher levels (as seen in the initial generic table). Perhaps the addition of a carbonation table much like the IBU by Beer Type table (see next page) would be a useful addition to EZBREW - what do you think? ________________________________________________________________________________ Page 68 TABLES ────── Some people like to be able to examine the data being used in calculations, or feel more comfortable using tabular data. No problem! This EZBREW Side-Menu option gives you access to three tabular data files useful to the home brewer - (1) International Bittering Units by Beer Type, (2) Keg Carbonation Levels by Volumes of CO2 Desired and Batch Temperature, and (3) a Conversion Table for Specific Gravity to/from Brix units. All three tables are accessed by activating the TABLES Side-Menu option, which generates the following screen: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Table Display ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌──────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Table to View │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │▓▓▓IBU by Type▓▓▓▓│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Keg Carbonation │██ ║ │ MATH ▄ │ ║ │ S.G. <-> Brix │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ ════════════════ │██ ║ │ TABLES ▄ │ ║ │ Exit to Main │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ └──────────────────┘██ ║ │ UTILITIES ▄ │ ║ ████████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ HELP! ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ EXIT ▄ │ ║ You have direct access to several tables containing ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ data you might be interested in by using the TABLES ║ └───────────────┘ ║ Side-Menu at the Main level of EZBREW! ║ ║ ║ ║ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ Since these tables are quite large, you will have to scroll through them to find the information that you are looking for. The first table, IBU Range by Beer Type, gives you some recommendations for bitterness levels for numerous beer types, as I have been able to get them from a survey of the literature. There may be some beer types that are not represented, but I think that a vast majority are in the list. If you do find one that's not here, drop me a line (with data) and I will put it into the list for the next release of the program. One thing to remember is that throughout EZBREW you will be presented with numerous recommendations for values to use. These are only recommendations, based on years of experience by hundreds of home brewers, and represent "best guess" limits that will produce brews that closely match a well defined style or type of beer that you may be familiar with from commercial sources. But by no means should you consider these recommendations to be "final", and I hope that if you are a true "hop head", you will experiment with ales that are hopped to your taste, even if the bitterness levels exceed those "recommended" for a particular type of brew (or below the lower recommended level if you don't like so much bitterness). Remember, you had some reason for developing a home brew capability, and making great tasting brews was probably one of them. So use the recommendations as a "guide", but experiment as you see fit! ________________________________________________________________________________ Page 69 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ IBU Range by Beer Type ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ╒═══════════════════════════════════╕ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Type IBU Range │ ║ │ REFERENCES ▄ │ ║ ╞═══════════════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Ale, Brown 31.0 - 38.0 ██ ║ │ GLOSSARY ▄ │ ║ │ Cream 20.0 - 70.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Mild 31.0 - 38.0 ▓██ ║ │ MATH ▄ │ ║ │ Pale 19.0 - 54.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ India Pale 11.2 - 24.0 ░██ ║ │ TABLES ▄ │ ║ │▓Alt▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓▓21.0 - 31.0▓░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Barley Wine 32.0 - 100.0 ░██ ║ │ UTILITIES ▄ │ ║ │ Bitter 23.0 - 44.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Bock 26.0 - 35.0 ░██ ║ │ HELP! ▄ │ ║ │ Dopplebock 28.0 - 40.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Dortmunder 18.0 - 26.0 ░██ ║ │ EXIT ▄ │ ║ │ Kölsch 21.0 - 31.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Lager, American Lite 7.0 - 19.5 ░██ ║ └───────────────┘ ║ │ Am.

Go down the left most column (Temperature) until you come to the row labeled 38. You are now at 38° F, the temperature of your batch.

Go up the column containing the 2.38 value until you enter the double lined box, where you will find the number 10. This represents 10 P.S.I., and is the pressure that is required inside of the keg in order to produce the carbonation that you seek at the 38° F temperature of the batch. Thus, you would set the pressure reduction valve on the CO2 cylinder to 10 P.S.I. to carbonate your brew to the level you want. The final table available is a tabular conversion between Specific Gravity and Brix units, and is straightforward in use. Be aware, however, that the note at the top of the table mentions that the conversion are valid only at 60° F, so if you use this table, be sure that all values have been collected at or are corrected to that temperature. ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Conversions between Specific Gravity and Brix ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║■▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒ Conversions at 60° F ▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒▒╗ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║║ ║ ║ │ REFERENCES ▄ │ ║║ Brix S.G.

EZBREW uses this table for various functions, but in particular the α-Acids calculations as you might well expect. The Hops table contains a list of the varieties of Hops that you might be interested in using in your brew, together with their corresponding AAU levels. So I'm sure that you can see that if you have a variety of Hops that has two or more AAU levels (obtained from different suppliers perhaps), you would have at least one entry in the table for each one. Notice the "at least one entry". When using the IBU approach to calculating bitterness, each time you added some Hops to the wort, you had to provide EZBREW with the variety and the amount of time you intended to boil it. In order to do this you tagged the appropriate Hops from the list of those available. Now suppose that you were going to add Spalt Hops at the beginning of the boil, and again at 30 minutes into the boil. Since you are making two additions of the same Hops, you have to tag Spalt Hops twice in the Hops Table. The only way you can do this at this time is to include Spalt Hops in the list twice, and tag each listing. Sorry about that, but you have to do what you have to do! But what if there is only one listing of Spalt Hops, or what if you need Jim's Special Hops and it is not even in the list? All you have to do is add it! And this is accomplished through the Hops Table Sub-Menu item. ________________________________________________________________________________ Page 72 Activating this Sub-Menu item produces the following screen: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Hops Table Maintenance Utility ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌──────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Action? │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │▓Look at the Data▓│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Add A Variety │██ ║ │ MATH ▄ │ ║ │ Remove A Variety │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Modify A Variety │██ ║ │ TABLES ▄ │ ║ │ Update Data File │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ │██ ║ │ UTILITIES▄ │ ║ │ ════════════════ │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ To Utilities │██ ║ │ HELP! ▄ │ ║ └──────────────────┘██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ████████████████████ ║ │ EXIT ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ └───────────────┘ ║ ║ ║ ║ ║ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ Selecting the "Look at the Data" Sub-Menu item will generate a list of the varieties of Hops currently available for your use in Scroll Menu format.

Move the selection bar to "Chinook" and press [┘ Enter] or click on "Chinook" with the LEFT mouse button. The NEW hops has been added to the table, and you are returned to the UTILITIES Sub-Menu screen again, this time with the "Add a Variety" item selected, indicating that you just came from there. To see the results of your addition, activate the "Look at the Data" item, and you will see a screen similar to that on the next page. JIMS SPECIAL HOPS has been placed BELOW "Cascade" and is located on the selection bar at the top of the display, while "Chinook" and all entries in the table following it have moved "DOWN" in the table one line. So inserting an entry causes all entries at the insertion point and below to move down in the table. Another way of looking at it is to choose the table location immediately following the entry after which you want the NEW entry to appear. In our example, I wanted JIMS SPECIAL HOPS to appear after "Cascade", so I chose "Chinook" as the place to put it! And by the way, EZBREW does not alphabetize or sort entries in any fashion. Throughout editing of the Hops table, EZBREW is actually working with a copy of the real table, which means two things. First, if you make a mistake, it can be corrected easily. And second, since the actual table is not modified until you physically instruct EZBREW to do so, you can always recall the original data at any time by ABORTING the editing (using the [ESC] technique or clicking the ________________________________________________________________________________ Page 74 LEFT mouse button when there is no data entered). Such safeguards may seen unnecessary to you at this point, but you may find them really useful later on. ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Currently available varieties and their α-Acid levels. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ╒════════════════════════════════╕ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Variety AAU │ ║ │ REFERENCES ▄ │ ║ ╞════════════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │▓JIMS SPECIAL HOPS▓▓▓▓▓▓▓▓▓▓6.0▓██ ║ │ GLOSSARY ▄ │ ║ │ Chinook 6.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Cluster 6.8 ▓██ ║ │ MATH ▄ │ ║ │ Comet 9.5 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Eroica 11.0 ░██ ║ │ TABLES ▄ │ ║ │ Fuggle 4.2 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Galena 13.0 ░██ ║ │ UTILITIES▄ │ ║ │ Golding 5.2 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Hallertauer 4.4 ░██ ║ │ HELP! ▄ │ ║ │ Hallertauer 4.4 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Hersbrucker 2.5 ░██ ║ │ EXIT ▄ │ ║ │ Mt.

Each and every entry in the °Extract table is actually made up of three components: (1). The name of the fermentable, (2). The estimated °Extract from the ingredient, and (3). A designation as to whether the item is a Grain, Extract, or Sugar. Notice that non-fermentable adjuncts such as dextrin, spruce essence, heading solution, etc. are not found in the table, as only those items that are actually fermentable (yeast food) are included, since it's these ingredients that will affect the alcohol content of your brew. This is not to play down the real importance of adjuncts in your brew, but rather is designed to help you to plan your brews strength (in terms of alcohol) with a minimum of fuss. I encourage you to experiment with adjuncts as you see fit. Modifications to the °Extract table are carried out in a fashion similar to those of the Hops table, taking into account the three items in each table entry mentioned above for each fermentable. Thus, when editing °Extract table entries, you will not only have to provide a name and °Extract, but you will also have to include a designation of Grain, Extract, or Sugar for each item you retain in the table. The significance of the "type" designation comes into play when mashing and sparging are taken into account. Theoretically, mashing and sparging do not influence an Extract or Extract & Sugar brew, except perhaps when straining out the hops. All of the °Extract derived from each item will likely end up in the primary fermenter therefore. But grains, on the other hand, are subject to the full influence of both mashing and sparging, and so are considered as a "special case" in EZBREW. ________________________________________________________________________________ Page 77 Another area in which the "GRAIN/SUGAR" distinction is important is when it comes time to determine the percentage of your brews total °Extract to be derived from Grains (which includes both Grains and Extracts [that are derived from Grains]). EZBREW needs to know which of the items you are using is considered as a Sugar, so that it can avoid using them in calculating the initial °Extract of the brew from Grain sources only. A brief review of the °Extract Side-Menu option will graphically demonstrate this feature. Activating the °Extract item in the UTILITIES Sub-Menu, the following screen will appear: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Degrees of Extract Table Maintenance Utility ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ┌──────────────────┐ ║ │ REFERENCES ▄ │ ║ │ Action? │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │▓Look at the Data▓│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Add An Item │██ ║ │ MATH ▄ │ ║ │ Remove An Item │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Modify An Item │██ ║ │ TABLES ▄ │ ║ │ Move An Item │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Switch Two Items │██ ║ │ UTILITIES▄ │ ║ │ Update Data File │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ │██ ║ │ HELP! ▄ │ ║ │ ════════════════ │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ To Utilities │██ ║ │ EXIT ▄ │ ║ └──────────────────┘██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ████████████████████ ║ └───────────────┘ ║ ║ ║ ║ ║ ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ Selecting the "Look at the Data" item will generate a screen similar to the one found on the next page. You can see that each item in the table has a °EXTRACT figure associated with it. Not shown, however, is the "type" designation, (Grain, Extract, or Sugar) although the name should give that away if it has been chosen wisely! Of course, as with any Scroll Menu, you can use the cursor keys or the mouse to move up and down in the list, since this is the only thing that you can do at this point. The list serves to acquaint you with what is in the table as well as where things are located. To get out of the list, [ESC] or a click on the RIGHT mouse button does nicely! Adding an item to the table is identical to the procedure used in the Hops table, except that you have to provide the "Type" designation at the prompt (see the next page). When entering the "Type" designation, the case of the letter you enter does not matter, so "G" or "g" work equally well for a grain and so on. Of course, you will be asked to verify that the entries you have made are "OK", but you should be used to that sort of thing by now. ________________________________________________________________________________ Page 78 ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Currently available ingredients and their °Extract. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ╒══════════════════════════════════╕ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Item °Ext │ ║ │ REFERENCES ▄ │ ║ ╞══════════════════════════════════╡██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │▓Jim's Special Beer Honey▓▓▓▓48.0▓██ ║ │ GLOSSARY ▄ │ ║ │ Pale Malt 34.0 ▓██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Crystal Malt 25.0 ░██ ║ │ MATH ▄ │ ║ │ Black Patent Malt 5.0 ░██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ Wheat Malt 36.0 ░██ ║ │ TABLES ▄ │ ║ │ Malt Ext.

These are "Move an Item" and "Switch Two Items", whose functions should be obvious. These two functions were included because I wanted the capability to easily move entries around in the table without the need to enter the same item as a new item at a different location in the table and then deleting the original! Thus, I could rearrange the table as my changing needs dictated. Using these two functions is as easy as drawing a draught! Just follow the instructions found on the screen as you go along and you will do okay. Altering the Specific Gravity Correction Table. ─────────────────────────────────────────────── The next item on the UTILITIES Sub-Menu is "S.G. Corrections". This item is used if you need to modify the ADDITIVE corrections that specifically apply to the hydrometer you are using to measure the "gravity" of your brew. Please note that the corrections made by EZBREW are only ADDITIVE in nature, i.e. you add a value to the reading you make in order to correct it to the calibration temperature of your hydrometer. If the corrections that you need to make are not ADDITIVE, you will not get the proper values by using this portion of EZBREW! Modification of the Corrections is identical to those made to the Hops table, so the mechanics of making changes should not be difficult to understand or master. However, the values in the table appear different, and thus bear some special explanation. Activating this item, you will see a screen that contains choices identical in nature to those found on the Hops table editing menu. Their functions are identical also. Activating "Look at the Data" will pop up: ┌───┤Options├───┐ ╔══════════════════ EZBREW Release 2.0 ═══════════════════╗ │ │ ║ ║ │ °EXTRACT ▄ │ ║ Hydrometer Correction Factors. ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀▀ ║ │ α- ACIDS ▄ │ ║ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╒══════════════════╕ ║ │ REFERENCES ▄ │ ║ │ (°F) Factor │ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╞══════════════════╡██ ║ │ GLOSSARY ▄ │ ║ │▓▓50.0▓▓▓▓▓▓▓-.5▓▓│██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 60.0 .0 │██ ║ │ MATH ▄ │ ║ │ 70.0 1.0 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 77.0 2.0 │██ ║ │ TABLES ▄ │ ║ │ 84.0 3.0 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ 95.0 5.0 │██ ║ │ UTILITIES▄ │ ║ │ 105.0 7.0 │██ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ╘══════════════════╛██ ║ │ HELP! ▄ │ ║ ████████████████████ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ ║ │ EXIT ▄ │ ║ ┌────────── Active ▄ ║ │ ▀▀▀▀▀▀▀▀▀▀▀▀ │ ║ │ ▀▀▀▀▀▀▀▀ ║ └───────────────┘ ║ ║ ║ This note tells you that the values displayed are ║ ║ the ones that are currently being used by EZBREW. ║ ║ ║ ╚═════════════════ (C) 1993 Jim Anderson ═════════════════╝ ________________________________________________________________________________ Page 80 Notice the "Active" memo at the bottom of the list.

Resetting the Mashing and Sparging Efficiencies. ──────────────────────────────────────────────── Altering the Mashing and Sparging efficiencies is simplicity itself - just activate the "Mash/Sparge Eff." item on the UTILITIES Sub-Menu and follow the instructions on the screen! The best way to learn how to use the options in the UTILITIES Sub-Menu is to get in there and give them a try. EZBREW was programmed to (hopefully) prevent you from making alterations that you don't want to, so go ahead, experiment and have some fun while you learn! In the worst case, you could always reload EZBREW over the one you messed up, and reset everything as it was initially. ________________________________________________________________________________ Page 81 HELP! ───── Often when learning a new software package, you find yourself in need of a little help. It does not matter whether or not you're an experienced computer user, you find that you are somewhat lost, and need assistance with the program you're using at the time. The HELP! EZBREW Side-Menu option is provided primarily for the new EZBREW user, and is intended to supply some "generic" help for each of the major program options available from the Side Menu.

While you are here, notice that the help box has a small solid square in the upper left corner. Place the mouse cursor on this square, and click the LEFT mouse button... the help box vanishes. This is the way that you "close" or erase a help window and return to the HELP! menu. The only way to get out of the HELP! Sub-Menu is to press [ESC] or click the RIGHT mouse button.

All other responses are ignored. And that about covers all of the major program options of this version of EZBREW. I encourage you to try some "dry" experiments just for the fun of it while you get used to the manner in which you interface with EZBREW, even if you don't actually brew them. That way, you'll become experienced with the program, and will be able to use it more completely as you strive for perfection! Remember, if you have any ideas about EZBREW, whether they are suggestions for improvement or comments of other sorts, I'll be glad to hear from you, especially if you send in your registration along with your comments, or you are already a registered user. But in any event, ENJOY! ________________________________________________________________________________ Page 84 EXAMPLE PLANNING SESSION WITH EZBREW Developing a Generic Brew Recipe Using EZBREW. ────────────────────────────────────────────── This section of the documentation is intended primarily for the novice home brewer who needs a little help in the overall plan for developing a home brew using the EZBREW system. If you are an experienced brewer, the utility of EZBREW will hopefully be obvious to you by this point (if you have waded through this manual and tried the program). You can skip over this section without loosing anything in the way of information. To those of you who choose to read this section, let me say that I do not intend for EZBREW to serve as a substitute for any of the many fine materials on the market specifically designed to instruct you in the methods of home brewing. Rather, I developed the program to help you to use your brewing skills in an environment where you could concentrate on what you were doing, and let all of the incidental stuff to the program. Thus some of the drudgery is replaced with a "cleaner", more interactive method for developing and/or checking home brew recipes. There can be no substitute for a thorough understanding of the basic brewing concepts - something that you can obtain through printed materials, but better yet through hands on training under the watchful eye of an experienced home brewer. Novice brewers might, therefore, wish to try making some "standard" recipes as found in the literature prior to using EZBREW, in order to gain the knowledge necessary to use EZBREW most effectively, as well as see how a typical recipe is constructed. Alternately, EZBREW could be used to "develop" a recipe by simply duplicating a recipe that has already been published, to see how things fit together, both in terms of ingredients, as well as program input/results. Assuming that you have a minimum amount of brewing experience (1 or 2 brews), this is how I would go about developing a recipe. First of all, decide on the type of brew you want to make (the implications are that you would also have to know something about the water at your disposal, but since such considerations are dealt with in the literature at some length and depth, they will not be presented here). You might decide that you wanted to produce a delicate Pilsener, or a more robust Stout. But whatever the case, deciding the general type of brew is your first goal. Having decided on the type of brew that you are going to make, the next step is to review the literature in order to gain all relevant information about the beer type that you can. Initial gravity, restrictions on ingredients (or the need for special ingredients), water treatments if needed, desired color levels, bitterness levels, etc. all need to be sought out and noted. This is perhaps the most "boring" phase of home brewing, but it is also the time when you begin to learn about beer in some detail - not all "beer" is created equal! Okay - so now you have the information in your hands, and you are ready to begin. First, go to the °EXTRACT Side-Menu option and begin to "fiddle" with the fermentables, varying the amounts of each that you use until you arrive at a mix that seems good to you (whatever that is), most probably based on the GRAINS/SUGARS ratio and the estimated Initial Specific Gravity. This will set the stage for the next step, determining how much hops to use. Record this information (print the screen) for later use and reference. Enter the α- ACIDS Side-Menu option, and determine the amount of hops that you will use in your brew. Since you already have an estimate of the Initial Specific Gravity, you should have no trouble. Again, when you have something that looks good, print it out or write it down. You'll be glad that you did if the brew turns out to be especially good (or bad)! ________________________________________________________________________________ Page 87 If you are unsure about Mashing and Sparging efficiencies, accept EZBREW's default values at first. As you gain experience with your brewing, you will learn how to modify the values to better match your level of capability. Armed with the list of fermentables, requirements for hops, and a desire to do good things, you now can begin your brewing. I will not go into the process any deeper than this, except to say that if you are a novice, you really should get some brewing literature in your hands before you attempt your first brew. You will learn about sanitation, yeast, malt, sugars, adjuncts, hops, "mouth feel", bitterness, carbonation (natural versus artificial), and techniques, techniques, techniques! Perhaps the single most significant ingredient in a fine brew is your time! Hopefully as you gain experience, you will be able to use EZBREW to a greater extent, and you might even come up with some ideas on how to make EZBREW a better program based on your brewing technique. By all means let me hear from you! This is exactly what I had in mind when I developed the program. But above all, whether or not you choose to use EZBREW, enjoy your hobby - and let me know if you create a "Prize Winner" (I'm always in the market for a good recipe!) ________________________________________________________________________________ Page 88 REGISTRATION Registration Information. ───────────────────────── A lot has been said about the benefits of registering as an EZBREW user, so I won't go over it all again. To register as an EZBREW user is simplicity itself. Simply fill out the registration form on the following page, and mail it to me with your registration fee (in U.S. funds only). Money orders are preferred, since they will have no problem clearing the bank (and will do so quicker), and I will be able to get your registered copy to you faster! You can send cash if you want to (again U.S. funds only), but you do so at your own risk. You can also print the registration form at the DOS prompt. Make sure your printer is set up to print out in ASCII format (ASCII codes above 127 [IBM line graphics stuff] are used), and type the following: TYPE REGISTER.DOC > PRN [┘ Enter] When I receive your form and fee, I will put together a disk containing the program, some Lagniappe as I mentioned before, and a brief, printed instruction page to get you going as quickly and with as little pain as possible. Once you receive your disk, you will be able to begin using the fully functional production release of EZBREW, you will be able to contact me and take advantage of all of the "extras" that registration brings. To those of you who do decide to register, let me say "Thanks!" Your support of the EZBREW system will help me to keep developing it in the future, and we will all benefit from your input into that process! ________________________________________________________________________________ Page 91 ┌────────────────────────────────────────────────────────────────────────────┐ │*Please PRINT Clearly!* REGISTRATION FORM FOR EZBREW *Please PRINT Clearly!*│ ├──────────────────────────┬─────────────────────────────────────────────────┤ │ Complete and return to: │ Please provide your complete mailing address: │ │ │ │ │ Jim Anderson │ _______________________________________________ │ │ 217 Rooks Drive │ │ │ Slidell, LA 70458 USA │ _______________________________________________ │ ├──────────────────────────┤ │ │ │ _______________________________________________ │ │ Jim's use only, please! │ │ │ │ _______________________________________________ │ │ Recd: │ │ │ │ State: ______ ZIP: _________ Country: _________ │ │ Auth: │ │ │ │ Phone (optional): │ │ Sent: │ │ │ │ Day: (_____) _____ - __________ ext ________ │ │ PCC: │ │ │ │ Night: (_____) _____ - __________ ext ________ │ │ │ │ ├──────────────────────────┴─────────────────────────────────────────────────┤ │ │ │ Qty Product (please specify disk size below) Price Total │ │ │ │ ___ EZBREW Home Brewing System. $30.00 $________ │ │ │ │ ┌─┐ ┌─┐ │ │ │ │ 5.25" disk │ │ 3.5" disk (Add $1.00 for a 3.5" disk) $________ │ │ └─┘ └─┘ │ │ │ │ Total enclosed (U.S. funds only please!) $________ │ │ (Make payable to "Jim Anderson") │ ├────────────────────────────────────────────────────────────────────────────┤ │ Please include a money order for the correct amount with your completed │ │ registration.

Just use the form on the following page (or print out the "COMMENTS.DOC" file to your printer) and let me know what's on your mind! If you're a registered user, I might even give you a call or write. I guess what I'm hoping for is user response. Although the program does suit most of my own needs, you might have a slant on things that I don't, and your contribution to the overall utility of EZBREW would be greatly appreciated and is heartily invited. ________________________________________________________________________________ Page 95 ┌─────────────────────────────────────────────────────────────────────────────┐ │ *Please PRINT Clearly!* COMMENTS/SUGGESTIONS *Please PRINT Clearly!* │ ├──────────────────────────┬──────────────────────────────────────────────────┤ │ Complete and return to: │ Please provide your complete mailing address: │ │ │ │ │ Jim Anderson │ ______________________________________________ │ │ 217 Rooks Drive │ │ │ Slidell, LA 70458 USA │ ______________________________________________ │ ├──────────────────────────┤ │ │ │ ______________________________________________ │ │ These comments are for │ │ │ which version of EZBREW? │ ______________________________________________ │ │ │ │ │ Version __.______ │ State: ______ ZIP: _________ Country: ________ │ │ │ │ │ Please provide your │ Phone (optional): │ │ PCC as found on the │ │ │ Opening Screen: │ Day: (_____) _____ - __________ ext _______ │ │ │ │ │ ______________________ │ Night: (_____) _____ - __________ ext _______ │ │ │ │ ├──────────────────────────┴──────────────────────────────────────────────────┤ │ │ │ Comments about EZBREW (use additional sheets if needed).
