---------------------------------------------------------------------- From: Rob Gardner (Digest Editor) Subject: Happy Holidays Just a quick note to let you all know that it is likely that there will be no digests during the next week or so. No great reason except some bean counters wanting to save a few cents by shutting down our computers for a while... I thought I'd be sure and announce this to avoid another inquisition like the one that occured last time the digest broke for a few days ;-) It is also possible that mail sent to the digest will be rejected, but if that happens, just try again in a few days, and try to relax!

Most people I speak to (including suppliers who deal directly with the company), call it "why-yeast". Wyeast Labs are located in the small town of Mt. Hood, Oregon, on the east side of Mount Hood. At 11+ thousand feet, Mt. Hood is glaciated and snow covered all year. The ancient Northwest indians had great respect for the god who lived in in mountain, and called him/her "Wyeast". I'm not sure what "Wyeast" means in the local Indian dialect, but I think I may have a reference to it at home. I'll check. There is a climbing route on Mt. Hood called the W'yeast route. > Anybody out there with authority on this? I'm not an authority, but I hope this helps. I'm sure some Portland brewers can speak more authoritatively.

Date: Thu, 20 Dec 90 09:25:55 mst From: hplabs!hp-lsd.cos.hp.com!ihlpl!korz (Algis R Korzonas +1 708 979 8583) Subject: Wyeast Attenuations A few days ago, someone (sorry) posted a list of attenuations and characteristics for Wyeast. The list was from an Alternative Beverage catalog. The poster speculated that the list was complied by Alternative Beverage. I double checked (I do that often now) at the brewery (read home) and found a four page "document" from WYEAST LABORATORIES which has the exact same data. Additionally, it has some other information which I will now proceed to type-in. Please note that I believe these sheets are at least 6 months old so some of the data may be dated. New Strains Added - Some Identification Changes Some new strains have been added to our product line. We have attempted to offer a wide variety of yeast types. Some of the strains have been more specifically identified to their geographic origin. For example, #1084 which had been considered British, we now know is more specifically Irish. We knew it was from the British Isles, now we know which one. As information about different strains becomes known, we will continue to make it available to you. Please note that all Ale strains are four digit and begin with 1, and the Lager strains are four digit beginning with 2. #308 is now #2308. The package label has the most popular strains listed right on it. In addition, other strains we have been selling remain available on request. Yeast Characteristics Some yeast strains are more active and vigorous than others. Lager strains in particular do not show as much activity on the surface as many of the Ale strains. We provide an adequate quantity of yeast to complete fermentation with varying amounts of lag time depending on strain, freshness, handling, and temperature. If you find it too slow, make a starter as recommended on the package. In any event, a closed fermenter with an airlock is recommended. Temperature The slow onset of visible signs of fermentation can be improved by starting fermentation at 75 F until activity is evident, then moving to your desired fermentation temperature. A few degrees does make a significant difference without adversely affecting flavor. The normal temperature for Ale yeast ranges from 60 - 75 F. A few strains ferment well down to 55. 68 is a good average. Lager strains normally ferment from 32 - 75 F. 50 - 55 is customary for primary fermentation. A slow steady reduction to 32 F during secondary fermentation typically works well. The fermentation rate is directly related to temperature. The lower the temperature, the slower the fermentation commences. Fluctuations in temperature such as cooling and warming from night to day can adversely affect yeast performance. Attenuation Apparent attenuation of yeast normally ranges from 67 - 77%. The attenuation is determined by the composition of the wort or juice and the yeast strain used. Each yeast strain ferments different sugars to varying degrees, resulting in higher or lower final gravities. This will affect the residual sweetness and body. Flocculation All brewing yeast flocculate. The degree and type of flocculation varies for different yeast. Some strains clump in to very large flocculate. Some floc very little into a more granular consistency. Most yeast strains clump and flocculate to a moderate degree. pH Ranges Typical pH range for yeast fermentation begins at about 5.1 and optimally 4.8. During the course of fermentation the pH reduces to typically 3.9 - 4.1 and a low as 3.1 in some wines. Alcohol Tolerances The alcohol tolerance for most brewing yeast is at least to 8%. Barley wines to 12% can be produced by most Ale strains. Pitching rates need to be increased proportionally to higher gravities. Alternately, Champagne and Wine yeast can be used for high gravities sometimes reaching alcohols to 18%. [Typing errors are probably mine] Al. Return to table of contents
Date: Thu, 20 Dec 90 10:31:04 CST From: Mike Charlton <umcharl3 at ccu.UManitoba.CA> Subject: Extract Efficiency The values quoted for extract efficiency seemed quite low to what I was experiencing, so I thought I'd look up my values to make sure. I discovered that I do indeed get better efficiency than other people have been claiming. For recipe formulation I use the table from Randy Mosher's article in Beer and Brewing Volume 8 (1988). He gives a table of MAXIMUM extraction rates for typical grains. While he says that efficiency should be about 85% to 95%, I find that I get about 80% efficiency. I'll just jot down the relevant information here: Ingredient Gravity for 1 pound in 1 US gallon Dry Malt Extract 47 Malt Extract Syrup 40 Corn, Rice 39.5 Wheat Malt 39 English 2 row lager, pale 37.5 English mild ale malt 36 German 2 row pilsner malt 35 German 2 row munich malt 34.5 Light crystal, Dextrine malt 32.5 Brown, amber malt 32 US, Canadian 6 row lager malt 31 Chocolate malt, Dark crystal 30.5 Black malt, Roast barley 30 Note that these are theoretical MAXIMUMS. You won't get these in your brewpot. In the origional question (6 lbs 2 row, 3 lbs wheat, 1 lb dextrine) I get a theoretical maximum of 74.9. Since the gravity was actually 53, this gives a mash efficiency of around 71% (a bit low in my opinion). I can see a few possible problems. The first is that your hydrometer may be measuring the specific gravity a bit low. Our hydrometer regularly gives a reading that is too low by about 4 points at 60 degrees F. The other possibility is that you are measuring your gravity when the wort is too hot. You have to make adjustments for wort that is above 60 degrees (although, this probably isn't the problem). Perhaps you aren't driving the starch conversion to completion. This is likely to happen if you use a straight infusion mash with North American or German malt. The problem is that the initial high temperatures of an infusion mash deactivate some of the enzymes in the malt. If this is the case, you will probably find that an upward step infusion or temperature controlled mash will help alot. Decoction will probably be even better. Step mashing is not alot harder than infusion mashing, so that's the way I would (and do) go. Finally, your sparge may not be very efficient. Taste the grains after sparging, if you notice any sweetness at all, then your sparge was inefficient. I use a double bucket system and have no trouble at all. I think that a starting gravity of 60 or higher is quite reasonable for the given recipe. If you are getting less than 30 points of extract for a pound of pale ale malt in a US gallon, I would take a look at your technique. You are probably making excellent beer, but it's a bit more expensive than it needs to be. Anyway, good luck! Mike Charlton Return to table of contents

I obviously can't cover every little detail of homebrewing here, but I have tried to give an easily followed outline of the process, along with most of the common pitfalls faced by beginners. I would welcome any comments or criticism on this section, as it will probably appear again, in hopefully better form. [1] The first thing I recommend to the new brewer is to find a source of brewing supplies. It may be a local brew shop or a mail order store. Check out books on homebrew either at a library or bookstore. The book I recommend getting is Charlie Papazian's "Complete Joy of Homebrewing." This is easily one of the best homebrewing books around, and it is very useful for both beginners and experienced brewers. There are lots of other good books around, so don't worry if you can't find this one. One caveat: stay away from books published in the UK, as these can be confusing and/or misleading for the beginner. They specify ingredients that aren't found in the US, and generally give poor advice, like adding lots of sugar. [2] The next thing to do is buy a kit. Most brew stores sell kits that contain everything you need to make your first batch, except for bottles. They'll cost anywhere from $35-$60 depending on how fancy they are. I'd recommend getting a kit that includes a 5 gallon glass carboy as well as a plastic pail. Other useful items that the kit might not include are thermometer and hydrometer. The kit should include: 10 gallon plastic pail, siphon equipment, bottle filler, bottle brush, bottle caps, bottle capper, fermentation lock, chlorine cleaner, and perhaps ingredients. If the kit includes a carboy, it should also include a short length of plastic hose for the "blow-by," and a funnel. There might be some other odd items, such as a stirring spoon. The major difference between one kit and another will be the presence of a glass carboy, so in this article I will indicate when a difference in technique is called for. If the kit does not include ingredients, there are usually several kinds of malt extract to choose from. Try to pick something not too heavy for the first time; a light or amber ale is a very good choice. Also try to get a hopped malt extract the first time to keep it simple. If none is available, then get 2 ounces of fresh hops if available. Failing that, get 2 ounces of hop pellets. [3] Relax, don't worry, and have a homebrew. Now you are about ready to start brewing. If possible, it is extraordinarily helpful at this point to find somebody who's done it before, and have them help you. Doing this will greatly improve your chances of success the first time, but don't worry if you can't swing it, your chances are still pretty good. Remember to tell yourself, "Relax, don't worry, and have a homebrew." The first time, ordinary beer will have to do, but do try to drink homebrew whenever you brew - it will help you to not worry. (Worrying can ruin the taste of your homebrew.) [4] To begin, you'll need a large pot to boil the malt extract in. The pot should be large enough to hold at least 2 gallons of water - the bigger the better. Fill the pot up about half way (whatever that happens to be) with water and boil it. The idea is to boil as much water as possible, but to have room in the pot for foam that will be produced by boiling. While the water is heating up, remove the label from the can(s) of malt extract, and put the can(s) in some hot water to soften the extract. When the water boils, put in the extract and let it boil again, stirring frequently so the extract doesn't burn. When it comes to a second boil, watch out - it has a strong tendency to foam up and make a legendary mess on your stove. When the foam rises, remove the pot from the fire and let it settle down a minute. When you put it back, it will have (slightly) less tendency to boil over, but it needs watching. [5] If you have hops or hop pellets, add them now, and boil the wort (wort == unfermented beer) for at least a half hour (an hour is better.) If you're not using hops, but instead, hopped malt extract, then it is not necessary to boil very long - 15 minutes is sufficient. [6] While the wort is boiling, you should sanitize everything that will come in contact with the beer. This includes the fermentation container, fermentation lock if any, utensils, everything. Sanitizing is done by soaking in a solution of water and the sanitizing chemical that came with your kit. A few teaspoons of household bleach in a gallon of water is quite effective also. I generally fill a large bowl with bleach solution and throw in everything to be sanitized. After sanitizing, rinse well with clean water at least 3 times. Notice I keep saying "sanitize" and not "sterilize." Well, it would be nice if you could sterilize, but you can't. Sterilization is very difficult, i.e., boiling under pressure for an hour, so sanitizing is the best we can do. Needless to say, be careful not to breath the fumes or get any sanitizing solution in your eyes. Sanitizing might sound like a pain, but that's only because it is. However, it's absolutely the most important thing you can do to make your beer a success. You can screw up a dozen other things, but if you keep everything clean, you'll still liable to brew a good beer. But if you're not sanitary, the finest ingredients and techniques won't help - you'll brew quite undrinkable beer. [7] Now put about 2 gallons of cold water into your fermenter, and add the boiled wort. A funnel is handy at this point if you are using a carboy. If your boiling pot is very large, use less than 2 gallons-remember, we're eventually making 5 gallons. (Do not pour the hot wort directly into a carboy with no water in it - you are likely to crack the glass!) If you added hops, you'll want to use a strainer to remove them, but don't worry if you don't get them all. Now fill your fermenter up to 5 gallons with cold water. If you're using the plastic pail, it helps if you've previously marked where 5 gallons occurs - a magic marker works well. If you're using a carboy, fill it up to several inches from the top. Depending on how much water you boiled, the temperature of the wort might be too high to add the yeast. If so, let it cool until it is below 90 degrees F. [8] Now the packet of yeast may be added to the wort. If you like, you can "start" the yeast. I usually do this to give it a "running start" and also simply to be sure that the yeast is good. To start the yeast, sanitize a bottle, and mix 2 teaspoons of corn sugar with a half cup of 80 degree water, and add the yeast. Stick a fermentation lock on top and let it sit while the wort cools. By the time the wort is cooled, the yeast starter should be busy fermenting, and you should see bubbles percolating through the fermentation lock. Now just dump the yeast mixture into the wort. If you're using a carboy, be careful when filling it with water to leave room in it for the yeast mixture. [9] After the yeast is added, put the lid on the plastic fermenter and attach the fermentation lock. Don't forget to put some water in the lock. If you're using a carboy, force the short piece of plastic tubing through the stopper a little bit, and put it on the carboy. Place the other end of the tube in a bucket of water. This type of fermentation lock is known as a "blow-by," and is necessary because the fermentation will produce lots of foam and sludge, and it has no place to go except out. If you used an ordinary lock, it would quickly fill up with garbage. In a plastic pail, there is plenty of space for the foam to grow. [10] Now put the whole thing into a cool, dark, place to let it ferment. Dark is important because sunlight can damage the beer. Cool is important because beer-fouling organisms don't thrive as well at lower temperatures. Room temperature is usually fine - about 70 degrees F. If you can get it to 65 or 60, that would be better. Don't make it colder than 60, however, because then the yeast won't work very well. (Most beginners will be using top fermenting yeast, which works best at 60 degrees and above. Bottom fermenting yeast works fine all the way down to freezing.) If you can't get the temperature below 80, then you should look for a better place to keep your beer. If you are using the carboy method, check the bucket daily for overflow. Signs of fermentation should appear within a couple of hours, and by the next morning, it should be fermenting madly. [11] After a few days, it will start to slow down, and will finish sometime between 4 and 10 days after you began. If you are using the carboy and blow-by, replace the blow-by with a fermentation lock when it stops blowing out garbage and starts blowing only bubbles. How will you know when it's done fermenting? If you like, you can take hydrometer readings, and wait until it stabilizes (same reading on 3 consecutive days.) However, I've found it works just as well to observe the frequency of the bubbles in the airlock. When you watch it, but don't see any bubbles for a few minutes, it's quite ready to be bottled. When it finishes fermenting, you don't have to bottle it immediately, but it's best to bottle it within 3-4 weeks of beginning. [12] The first step in bottling is to acquire bottles. Go to a liquor store or bar and pay $2.50 for 2 cases of empty deposit bottles. Do not use the throwaway kind with the screw-off tops, as these are not strong enough. Chances are the bottles will be pretty scummy, so pour an inch or two of strong bleach solution into each, and let them sit for an hour. Then rinse them well, using your bottle brush if necessary, and your bottle washer if you have one (see issue #1.) [13] If you fermented your beer in a carboy, siphon(*) the beer into the sanitized plastic pail, and add a boiled solution of 3/4 cup corn sugar and water. If you used the pail to ferment, then you must "prime" the bottles with 1/2 to 1 teaspoon of sugar each. This added sugar is what produces the carbonation in the bottles. Do not use more than 1 cup per 5 gallons or 1 teaspoon per bottle, or you risk the danger (and social embarrassment) of exploding bottles. [14] Now fill the bottles with the siphon and bottle filler, and cap them. Store at room temperature for at least a week, then try to move the beer someplace a little cooler. (I keep mine underneath a window.) The beer should be drinkable 3 weeks after bottling, depending on ingredients. You might want to try a bottle every week after bottling just to taste the changes that occur. * siphoning: don't suck on the tube to start it, that will introduce lots of bacteria into the beer. A good trick is to fill the siphon with water to start it. Remember that the level of liquid in the source container must be higher off the ground than the top of the destination container in order for the siphon to work. Now don't rush to brew the second batch quite yet. Why not wait a few weeks and see how the first turned out? That way, if you really did something wrong, you have a chance to find out what, and avoid the problem in the second batch.

A couple of the things we >discussed, I think, are worthy of bringing before this group, partly for >their informational value, and partly because they might prove to start >some discussion.

If *he* can >be limited this way and sell tons of beer that most consider really tasty, >what do we amateurs gain from our complicated mash schedules, decoctions, >etc.? It's really got me wondering. Is single-step mashing *really* limiting? I guess that depends on what you are trying to produce. Single-step infusion mashes are fine with pale ale malt, which is very highly modified, i.e. the malting process takes care of a lot of the large proteins present in a less modified lager malt. Most homebrewers don't use (and probably don't need) an acid rest. The protein rest serves to break down the larger proteins present in lager malt. One could skip this, dropping the large haze producing proteins out with our friend, Irish Moss. Of course, too much Irish moss drops out too many proteins, and poor head formation/retention results. Actually, the only time you really *need* to do a protein rest is if you are using flaked barley as an adjunct. Flaked barley contains a lot of beta glucans, and the enzyme that breaks these down (beta glucanase) is active in the temperature range used for protein rests. Too many beta glucans give you problems with wort viscosity, like hard sparging, and low extraction. >The other thing he said that stuck with me was that, relatively >speaking, there's something *wrong* with fermentations that don't come >to their conclusions within what I'd consider pretty short periods of >time. Depending on temp, 3-4 days for ales and 6-7 days for cold-fermented >lagers. For what it's worth, my ales usually are pretty well done fermenting (i.e. < 1 glub/minute through the airlock) in about 3 days at 75F. Of course, I rack to a secondary and let it settle out for say 5-10 days. This also gives me a chance to dry hop if I want/need to. Yes, I aerate the daylights out of my cooled wort. Firstly, I syphon out of the boiling kettle and let it drop 3-4 feet into the primary (plastic primary). I then give it a good go with a wire wisk, pitch the yeast, and give another go with the wisk. Yes, the wort is at or below fermentation temps when I do this. I can't say about lager fermentation, but cold wort should hold more O2 than 75F wort. I would suppose that with optimal aeration of cold lager worts, that 7 days shouldn't be unreasonable, given a high enough pitching rate. Of course it all depends on temperature. In the final analysis, what works for you is all that really matters. Different equipment calls for different techniques. If you are using a picnic cooler as a combination mash/lauter tun, you don't have many choices as far as mashing. You either do single-step infusion, or decoction. Different styles call for differing methods. For example, Pilsner Urquel does a double decoction mash that takes 6 hours. They could produce a similar wort by single-step infusion, but it wouldn't be quite the same. The lighter styles, like pale lager, leave little to hide behind. At that point, everything you do is going to have a subtle impact on the flavor of the finished product (and not everyone is going to be able to taste whether you boiled for 60 minutes or 120, or used Irish moss or not, etc.). The brewmaster of a brewpub is only one data point, and whatever works for him may or may not work for the rest of us. The fact that he produces relatively large quantities of beer that folks find tasty is a rather moot point (look at how many people like Bud/Coors/Miller/Olympia/etc. If they didn't, these companies wouldn't be in business). >Brian Capouch =============================================================================== Todd Enders - WD0BCI ARPA: enders at plains.nodak.edu Computer Center UUCP: ...!uunet!plains!enders Minot State University or: ...!hplabs!hp-lsd!plains!enders Minot, ND 58701 Bitnet: enders at plains "The present would be full of all possible futures, if the past had not already projected a pattern upon it" - Andre' Gide =============================================================================== Return to table of contents

Question: Is the date encoded in the label notches the bottling date, or is it a sell-by date? I always assumed it was the bottling date, but tonight I drank a bottle of Young's 1990-91 Winter Warmer and the notches yielded a date of January 27, 1991. So either it's a sell-by date, or my decoder doesn't work on Young's.

I'll buy that. I haven't been to a large number of brewpubs, but every one I've been to uses either extract or a single-temperature infusion mash, for exactly the reasons stated. > ...

Me too, up to a point. I make ales, but not with British ale malt, and find myself increasingly using a single-temperature mash, unless I have fairly high adjunct levels. My "house stout", for example, with its flaked barley and roast barley, still gets the full step-mash treatment, but my last batch of bitter, mostly pale malt with some crystal and a little wheat malt, was mashed at a single temperature, without apparent damage. I remember reading an article by Greg Noonan, that indefatigable champion of the decoction, where he seemed to be saying that the type of mash used was largely a function of the malt. If the malt was well-modified and in good condition, an infusion or step mash would suffice, but if it was anything less, only a decoction would do. And that may be the secret: perhaps the quality of presently available malt allows a simpler approach. Perhaps I'm getting away with infusion-mashing a lager malt because I so rarely refrigerate, except in mid-summer, so chill haze is never a factor. And maybe the brewpubs get away with the same by cold-filtering, to remove the chill haze precipitate. = Martin A.
