I have used it in 4 batches and found that my comments mirror those of Alex Santic below: "I've made 3 fine batches with 1275 and experienced no imbalance of esters or phenolic off-flavors. In fact, it seems like a relatively neutral strain. The reported results can be easily explained on the basis of common procedural problems. In particular, many people ferment ales at relatively warm room temperatures. Alex Santic NYC" Return to table of contents

I really like this beer and I think its the best thing I ever out of a container with the AB initials on it. I can recommend this beer to anyone that likes wheat beer. I just wish they woulda used a german wheat beer yeast. One thing though, I think they might have used a tad bit too much bittering hops. I would like to have seen about 20-25% less.

If folks were truly dissatisfied, then they should do something. I said (sorta) that the time had come to fish or cut bait, put up or shut up, **** or get off the the pot. In response to my offer of meager assistance, I got exactly two (2) answers. Both guys said that they egreed with me, and had as little time as I. Since I have no ax to grind, and no burning ambition to start something...well, that's that. I'd also like to thank the HBD software for NOT cancelling me when I requested it. It seems to be back to its old self, again. Joseph M. Labeck, Jr. joe-sysop at cyberbury.net Writer, House-husband, Dad "If you tell the truth, you don't have to remember what you said!"

Date: Fri, 28 Mar 1997 05:31:20 EST From: petersonj1 at juno.com (John C Peterson) Subject: Kent Dog Hops/Thanks to all/Spam-o-rama I first want to THANK the few that helped me pass on the "don'ts" of homebrewing to the newbies. I have made a web page for this. It's a little rough right now, but please visit it and critique me (private email). www.geocities.com/Yosemite/6841. Then follow the link to Don't! I also have some good recipes there. Now on to the Dog Hop. I just got done with making a Bitter and thought I'd try out this killing theory on my bird dog. First, the only time he not right at my feet in the kitchen is when I'm brewing beer. Second, he loves beer. So, while cleaning up, I had dropped some of the, now cold, hop leaves on the floor (after soaking in wort for 60 minutes). If this was food, he wouldn't have allowed it to touch the floor. He sniffed it and snorted (his way of saying he's pissed off). I did this with Kent Goldings and Cascades. My prognosis, until I hear from someone who's dog died eating hops fresh or just out of the wort, the subject is dead. As for the Ad-spams everyone seems to be getting. I have one email account that I use for this sight and another that I use for the web and newsgroups including rec.beer (Aol :-( ) I haven't been spammed on this account, but I have started getting unsolicited mailings on the aol account. Could it be the newsgroups? Experience alone tells me Unix has an easier time extracting mail headings from newsgroup than from email digests. John C.

Kanous II" <nkanous at tir.com> Subject: Fermenting in Sankey kegs Greetings to the collective: I was thinking of removing the dip tube, etc. from a Sankey keg so I could use it as a fermenter. I thought it would be much more practical to have a stainless steel fermenter with two large handles for moving beer in and out of my chest freezer (a.k.a. fermentation/lagering "room"). For those of you out there that use these, there must be some, how do you clean them and how do you know that they're clean? TIA Nathan in Frankenmuth, MI Return to table of contents
Date: Fri, 28 Mar 97 07:52:14 UT From: "C&S Peterson" <CNS_PETERSON at msn.com> Subject: Decotion Kick-ins HBDers: Several posts to follow...... Chris Cooper asks about tannin extraction in the decoction process. He is quite right in that many texts warn of boiling grains, and then turn around and speak of the virtues of decoction mashing without stessing two points: 1. keeping you pH low in the decoction is of paramount importantance. I would not recommend decoction mashing unless you had a very reliable way to measure your mash pH (eg: don't trust the el-cheapo test strips, get the expensive ones!). I pH of 5.8 or higher (measure a cooled sample) will extract tannins and phonols, turning you beer into slug bait. 2. Some tannins are extracted in the decoction but most precipitate out (I think other HBDers suggest this happens as well). Brian Pickerill goes out on a limb and suggests the following categories for making beer malty: 1) Using lesser modified lager malts and decoction. 2) Using No-Sparge brewing. 3) Using munich malt. Now I'd like to jump out of the tree........ My $.02 is that the malty flavor decoction comes from maillard reactions/carmelization of the mash (BTW, are these two flavor sources one in the same, or should they be considered different?). An intereresting point here is that you can simply carmelize the first runnings of your mash to get some (and maybe all) of the benefits of a decoction. So maybe #1 here should be maillard/carmelization. The no sparge brewing is simply a low (ideally zero) ratio of sparge to grain. So what you're really doing is using extra malt and stopping the mash run-off at a high gravity. Isn't the "no sparge" process the same as I use for a doppelbock (e.g.: for a high gravity wort, I lose a little efficiency and stop the sparge early). Brian is definately on the right track here; I think that the "no sparge" is simply the logical extreme of the sparge to grain ratio. Maybe a beer made from second runnings would be the other end of this logical range. Using colored malts clearly adds malty character. But I think there's something missing here. Malt complexity. Every been to a single-infusion brewpub and had one of their "maltier" selections? Kind of one-dimensional. I think the thing decoction brings to some beers (and not all beers -- a "simple" malt profile is great in a bitter, IMHO) a complexity in the malt profile that is desireable. Step infusion does this too, but IMO to a lesser degree. Louis Bonham posts the results of his experiment, which I find very relevant to this discussion. It seems to support the hypothesis above, e.g.: that although the RIMS beer was "maltier" in flavor, the decoction was more pleasing to some. Louis suggests that maybe the formation of phenols in the decoctoin is responsible for this. [Big Note: Louis, this sounds like a great experiment. Not to mention a Munich Helles is one of my favorite beers -- Yum. It may be though that significant carmelization occured during your RIMS process? Especially if the RIMS beer was darker than the decoction, which given a tripple decoction was used is surprizing. You may not want to hear this, given all the work already put in to your experiment, but it might have been interesting to compare the decoction with a traditional step infustion via boiling water. While there are more and more homebrewers building RIMS, my guess is that most considering a decoction are moving from an infusion or step-infusion process. In short, decoction is a quick and dirty way to create carmel and perhaps other interesting flavors in beer.] So maybe there are 4 ways to describe malt flavor volume and complexity: 1. boiling of grain (malliard + phenol production) 2. boiling of wort (malliard/carmelization) 3. sparge to grain ratio 4. malt selection (e.g.: munich, crystal, etc) Note that in a dopplebock (deoction mashed), all four are used. In a kolsch (infusion mashed) maybe only #2 is used if you want to add a little maltiness via carmelization of the first runnings. And I agree with Louis -- great beers can be made from single, step, or decoction mashing. Not to mention extracts. Finally Jim Wallace asks about a Weizen mash strategy. My suggestion is to go with a rest mash of 135 to 138, as suggested by many here in the HBD. In an all-wheat beer I made in December, I used the 122 rest and regretted it -- the body was OK but the heading properties were so-so. Clearly, I denatured the proteins too far in my protien rest. My mash strategy for next time? I'll rest at the 135-138 range, and try to keep the mash as thick as I can at this point (like 1Q/# of grain). And remember this was for a 100% wheat beer (I used Durst) -- you should have less of a protein problem with a 60% wheat grist; I would think you would want to stay away from the 122 even more.

In one of the few posts on this subject someone suggested that the Wyeast AbbeyII was the Rochefort yeast.

Date: Fri, 28 Mar 1997 08:58:07 -0500 (EST) From: Bruce Johnson <brucej at arches.uga.edu> Subject: lager or not?/oxidation effect? I just started brewing in Jan. I have a few newbie questions. First, is a beer a lager if you use lager yeast and the normal ingredients for a lager, but you brew at ale temp. and don't age it? If not, what is it? Second, what affect does aerating your beer while racking to a secondary have on the beer. I didn't do this on purpose obviously. How will it affect the taste? It is still in the fermenter. Third, I haven't been filtering out the hops(pelletized) from the wort before putting it in the fermenter. Should I? What difference will it make? Fourth, my friend just made a pale ale that has a lactic taste to it. What could be responsible for that? He said the temp. fluctuated during the fermentation. Could that be the cause? I know these are pretty simple questions for this group, but any info. would be greatly appreciated. Thanks in advance.

Date: Fri, 28 Mar 1997 06:38:38 -0800 From: popeman at webtv.net (Tom Pope) Subject: AHA Competition Bill Giffin has again criticized the the AHA and their competition. It's evident Bill doesn't like the AHA, and he is entitled to his opinion and he certainly doesn't have to enter the competition or buy the magazine. I do believe, however, that his remarks concerning the judging are unfair and untrue, at least in my experience. I can only speak with respect to the AHA regionals held in California each year. I have judged or helped organize the California event for the past three years, and I can state with certainty that highly qualified and experienced BJCP judges work very hard to give each entrant the benefit of their expertise. Each entry is judged fairly and competently. If this has not been Bill's experience with the AHA competition held on his side of the continent, so be it. It is not the case here. For Bill to maintain otherwise is an insult to the integrity and the hard work of all the judges who participate in the California AHA regionals each year. Frankly, Im a little surprised that judges who participate in some of the other AHA regional sites haven't voiced their disagreement with Bill on this issue. I am not defending the AHA per se, but I do feel slighted by Bill's remarks about the judging. The Pope of Corte Verona Return to table of contents

Date: Fri, 28 Mar 1997 10:41:51 -0500 From: "Reed,Randy" <rreed at foxboro.com> Subject: RIMS Step Mashing/Trip to Wales/Homebrewer's Diet (Randy Reed) I have always wondered if there is an effect on the wort composition due to the timing of increasing temperature steps. I mash in a propane fired ? barrel (ten gallon brew length) RIMS system. I recently did a step mash as recommended by Dr. Fix's literature. In order to not scorch the wort, I raised the temperature of my mash each time very slowly. I always try to mash in a few degrees low and bring the temperature up slowly so as not to overshoot the rest. 1. The main question is, how important is it to raise the temperature to the next step relatively quickly, or are gradual increases in temperature not a problem? What says the collective? 2. In about two weeks, I will be in Cardiff, Wales area (reading HBD from the laptop). Can anyone recommend to me (via private e-mail) the best way to spend my beer hunting time? I am looking for brewery tours (Brains does not offer one this time of year) and the best pubs. 3. Can any nutritionists out there recommend the best diet for an over-weight home brewer? I drink about 2-3 pints of home-brew or craft brew a day. Since beginning my brewing 4 years ago, my weight has steadily risen. Light beer will never be brewed in my basement, and I do not wish to drink less beer. After all, a beer judge must do his research... What portion of my diet that I can reduce in order to better balance the wonderful empty calories of beer? (Less bread, carbohydrates?...)

The (loose) concensus seems to be that they may be okay for countertop surfaces, but that's about it. For those with apparent concerns about "stealing" from my employer, this is not the case. Through a typical corporate snafu, a case of these were sent to my office. Upon being informed, they do *not* want them returned (go figure). In short, they will sit in my office for about three years, get a nice coating of dust and then someone will throw them out during a housecleaning binge.

Date: Fri, 28 Mar 1997 12:00:43 -0500 From: "David R. Burley" <Dave_Burley at compuserve.com> Subject: Decoction Brewsters: Charlie Rich partially quotes me and gives me the opportunity to once again say - if one is giving advice on temperature and holds it is necessary to indicate the type of malt and grist composition being used. In my discussion I was addressing predominantly the case for people who wanted to decoct pale ALE malt. Malts that do fine in single malt infusions - AKA pale Ale malts already have plenty of protein and parking at the protein rests at 135F will produce perhaps more Mid-Mw protein than desired. This could lead to excessive chill haze. I suggested for pale ALE malts to avoid this problem, move to 145F and allow it to drop to 140F or so over the time it takes for the decoction. The reasoning being that If this malt is fine for a single temperature infusion it already has the correct protein balance, etc. Moving to 145F is in the middle of the beta amylase region, but so what? Limited alpha activity at this temperature does not give the beta anything to operate on, so very limited simple sugars get produced. The reason for moving to 145F was to denature all the proteinaceous enzymes so as to not upset the protein balance in this malt intended for a single infusion. BTW it is not the purpose of the decoction to "cook" the malt, but rather to carry out a reaction that proceeds rapidly at the boil and ultimately produces melandoins, gelatinization of the starch is a side benefit If sufficient enzyme capacity is available in the main mash. The whole point of taking less than all of the grist from the mash and decocting it was to make sure that enzymes still were there after even a triple decoction as your calculations confirm. This is exactly the point. It was never intended that all the malt would be decocted, even in a triple decoction in which one-third of the grist was taken each time. Taking a decoction on 8 -10 lbs of wet grist has to be extremely difficult, not to mention the heating problems, preventing scorching, etc. I estimated in a previous HBD submission that at the very minimum one-third of the enzymes are in the malt. I suspect as much as 50% enzyme content in the grist, in the absence of real data. If you start with a pale ALE malt which has an inherently lower enzyme content, then starch conversion could be slowed considerably. High temperature saccharification ( at 158F which I favor) in the main mash may suffer in this case because of a diminished beta concentration at the outset of the saccharification step. - ---------------------------------------------------- Like Bill Giffin I think the AHA's attempt to grab publishing rights ( and who knows what else) to your recipe by copyrighting it is sneaky, sinful and no one should do it. I'm not sure how they propose to do it since you created the recipe. If the AHA really only wants to be able to publish it, the brewer should be asked to sign a release to the AHA to use it in Zymurgy only upon entering the contest. If they want to use it in a book, video tape or other publication method, they should share royalties with the authors. If it makes it to the top do they get a share of something which they signed with Boston Beer and we know nothing about? Also, if they do copyright it as they plan, what share does the author get of the royalties?? Lots of poorly thought out things here. Sign a contract which has all of this stuff worked out OR even better copyright it yourself BEFORE you submit your beer, make a date record by having a notary public certify the date and send them a release, including a statement similar to that used on software packages. If they accept your beer in the contest, they agree to your terms. To maintain what little credibility they have in this matter, the AHA needs to think this through clearly, make sure everybody gets what they deserve - and nothing more - and carry on with the contest. - --------------------------------------------------- Keep on brewin' Dave Burley Kinnelon, NJ 07405 103164.3202 at compuserve.com Dave_Burley at compuserve.com Voice e-mail OK Return to table of contents

Date: Fri, 28 Mar 97 13:49:00 PST From: Martin Wilde <Martin_Wilde at ccm.jf.intel.com> Subject: Re: Decoction mashing Text item: Text Item Greetings! I enjoyed reading the threads on decoction mashing recently. I have tasted many locally brewed Helles Bock style beers and Pilseners and brewed many of them myself. I can definitely taste a difference in decocted ones and non-decocted ones. There is a definite "breadiness" which results from the decoction. A local brewery - Saxer produces a dopplebock which uses a single step decoction and once again the breadiness shows up from the decoction. This flavor which I call "breadiness" is what separates some of the great German/Czech style lager beers from the rest. I've been to Munich and tasted Munich Dunkel's brewed with both decoction and non-decoction - there is a difference in flavor. The non-decocted ones are bland and the decocted ones are terrific. If you have ever tasted Ayinger AltBarisch Dunkel you will know what I mean. I don't believe all the Munich malt in Munich can give you that flavor. I don't know how you can brew a Czech pilsener using Munich malt and get that decoction flavor since the Munich malt is ~6 to 10L in color and most pilseners are 2 to 4L in color. Budweiser Budvar is an example of this. For the last several years the Oregon Brew Crew has had a pilsener competition and you can definitely taste the difference in pilseners which are decoction mashed and those which are not. I am not talking about "malty-sweetness" but about more mouthfeel and overall more complex flavors from the Maillard effects of decoction. Martin Wilde 264-4328 Return to table of contents
Date: Fri, 28 Mar 1997 13:55:59 -0800 From: Randy Erickson <RANDYE at mid.org> Subject: What are these chemicals? Jim Anderson, who works for a "major airline", perhaps the one centered in SLC from the looks of his domain, informs us that the radio microphones and other cockpit controls are sanitized with these nifty little towellettes that contain, among other things, a spermicide!

One comment in general paticularly bothered me. > Why would anyone want to enter either of these competitions? Both are only > for the gradification of the competition not the brewer who enters.. Bill, just because you dont enjoy competition dosn't mean others dont as well. I truley enjoy hombrew competitions and have recently started judging and I find your comments insulting. Asuming others feel the same way as you do could turn off alot of homebrewers from entering and participating in competitions and enjoying the process immensely. To make this short I will not continue to argue but instead urge brewers to decide for themselves (interesting concept Bill). Dont just enter a competition, take part in it. Talk to the organizer about stewarding or just stop by and observe. Its a great way to socialize and learn about HB, and its always fun to win, or just to get some interesting feedback from the judges and other brewers. If you dont have fun, dont do it again, if you do you might find yet another rewarding aspect of brewing. And just remember, judges are simply fellow brewers and there opinions are simply that, educated opinions. Nathan Moore Denver, CO Return to table of contents

Collins Mash Tongues Mashfest. Got a silver for an ESB. (http://www.fortnet.org/~smills/mf-win97.html) We first entered this competition last year and got nowhere but the judges comments were invaluable. We started controlling fermentation temperature and added more aroma hops to our recipes and our beers improved dramatically. So, might I recommend to one and all the advantages of entering competitions? It's nice to win but the main benefit was to hear impartial constructive criticism of one's beers. It's possible to learn a lot of brewing theory and practice from books and the HBD but before entering the competition last year all I'd heard about my beer was that it was unequivically great, usually from friends and family. And they're never going to be rude! Or insightful. Here's a brief version of the recipe. Rebate Ale Recipe Makes : 11.0 gallons Total Grain : 20.50 lbs.

Date: Fri, 28 Mar 1997 23:56:45 -0500 From: ajdel at nospmindspring.com (A. J. deLange) Subject: Hemacytometer Wolfgang Wedel asked about use of a hemacytometer. See The Microbrewery Laboratory Manual - Part I by Fal Allen in the July/August 1994 issue of Brewing Techniques. A fair part of this article is dedicated to the use of the hemocytometer (as it is spelled in the article and that is probably the preferred spelling). In a nutshell, the hemocytometer contains a well 0.1mm deep and the floor of this is ruled forming a counting area 1 mm x 1 mm. The counting area times the depth (0.1 cm x 0.1 cm x 0.01 cm) is .0001 cc (mL). The counting area is subdivided into 25 squares (let's call them "little squares") by multiply ruled lines and each of these is in turn subdivided by single lines into 16 squares ("tiny squares"). To use the device place a cover slip over the well and intoduce a drop of pitched wort under the coverslip. Capillary action will draw this into the wells (there are 2) and float the coverslip at the correct depth. Look at the slide under low power and start counting the cells in one of the 25 little squares. Use the rulings for the tiny squares to help you keep track of where you are in the little square. A hand counter is very, very helpful here. Count cells which touch the upper and left walls of the little square but not the lower and right walls. These will be counted when you do adjacent little squares. Count daughter cells only if they are at least 2/3 the size of the mother cell. Count all 25 boxes in this way and multiply by 10,000. That is the number of cells per mL. For better statistical stability, count the other well also and average. If the cells are dense you can count only 5 little boxes (the four corners and the middle) and then multiply by 50000. * * * * * * * * * * * * * * * * * * * * * Chris Cooper asked whether boiling the grains in a decoction causes the leaching of tannins. Indeed it does but the boiling allows some of these to complex with proteins to form a precipitate which is trapped during subsequent lautering and sparging. The remainder complex and fall out during lagering. Note also that the pH in the decoction boil is usually close to 5 so that helps some. A.

Date: Fri, 28 Mar 1997 17:08:46 -0800 From: Mark Riley <mriley at netcom.com> Subject: Starch in crystal? Hiya HBD, Lately, I've had a few questions regarding the steeping of grains. One of the things I have been interested in determining is what "efficiency" you get when steeping crystal for an extract recipe (I need this information so I can fine tune the calculations for extract recipes in the Beer Recipator - see the URL below). So, I did a little experiment where I basicly steeped one pound of 40L crystal in one gallon of room temperature water and then brought this just to a boil (about 20 minutes), at which point I removed the grains. I used this steeping procedure for this first experiment since it is used a lot in TNCJoHB and I assume since there are lots of copies of this book in print, a good number of extract brewers probably use this method. I ended up with an SG of 1.014 for this "wort". The Zymurgy Grain Special Issue tells me the threoretical SG is 1.034 for 40L crystal so I have a 41% efficiency. That's good to know and I plan on doing more experiments to get better numbers. That 1.014 SG represents the dextrins, sugar, starch, etc... that were released while steeping the grain. Yep, you heard me right, STARCH! I did an iodine test, and somewhat to my surprise, got a distinct positive result. Now, I've read here and elsewhere that starch in your beer is not a good thing. Starchy beer supposedly doesn't taste good (haven't had any myself - that I know of), but as George De Piro noted earlier, starch may encourage a low-grade infection since some bugs (bacteria) can process it and not have any competition from the yeast. While steeping crystal certainly adds flavor to an extract recipe, perhaps using this method of steeping, which seems to be releasing some starch, may cause the beer to deteriorate quicker if any starch munching bugs are present. In any case, I'm going to try this experiment again by steeping the crystal at 150F for 30 minutes and see if I don't see different results regarding the starch. BTW, the crystal I used had a good crush, the same I've been using to get 85% efficiency in a regular mash. Prior to this, I did another experiment where I steeped some crushed chocolate and roasted barley for 15 minutes at 170F to 180F and got a negative result on the iodine test, as far as I could tell, since the "wort" was pretty dark.

While I don't have a source, I can describe it as I've used one. The Hemacytometer has a grid pattern on it. There are 5 large vertical and 5 large horizontal lines across the face of the device, which is about 2.5 inches tall by 3.5 inches wide. This makes large squares on its face. Within each of these squares are smaller lines, which create 25 squares within EACH of the larger squares. You put a sample of your beer in the hemacytometer, and then place it under the microscope. You can count the number of single cells within the squares to guesstimate your yeast concentration. The suggested accurate way to estimate your cell content is to count every yeast cell within all the smaller squares within a checkerboard pattern of the larger squares. Hope that's easy to follow. In addition you can stain your yeast with methalyne blue. The dead yeast absorb this blue dye, while the live ones don't. This way you can not only figure out your actual cell concentration, but also the viability of them.

This is basically the same setup that I use except that I don't use the drilled rubber stopper and I didn't drill a new hole in the wall of the cooler. I use the existing hole from the removed drain. I had problems with leakage with the drilled stopper no matter how tight I crammed the thing in there. What I now use is a bung from a 5 liter minikeg. It's a tight fit but once it is in there it forms a perfect seal. 3/8" tubing fits tightly inside the bung and forms a good seal.
