That's not quite it. Back some 170 years plus when the brewery was founded, this part of Germany belonged to the Kingdom of Bavaria. They tried to change the name to something more regional in the early 1980's, but the locals were aghast that their beer heritage was being tampered with (that and sales dropped dramatically :-). and then: Jay Hersh <hersh at expo.lcs.mit.edu> writes: >This isn't however a ferment it is an aging (aka lagering), by the time it hits >these cold cellars it should have done most if not all of it's fermenting. Yeah, you're right Jay. They do the ferment in big inverted conical steel thingies, then lager in (I think) wooden casks. Not all the beer goes thru this process. Got typing faster than I was thinking.... Also, they said they made Clausthaler, the Non-alcohol beer there. This would mandate additional equipment that wasn't shown to us on the tour, so I'm sure I missed out on a lot. I think the language barrier played a big part.

Date: Tue, 04 Feb 92 08:53:31 CST From: Fritz Keinert <keinert at iastate.edu> Subject: Kvass, anyone? A friend of mine of Lithuanian descent told me about a drink they make there for special occasions, based on fermented rye bread. Some time later, I checked out a Russian cookbook from the library, and they also mentioned a drink called "kvass" based on fermented bread. I assume they were talking about the same thing. The cookbook did not give any details. Does anybody know more about this? - ------------------------------------------------------------------------- Fritz Keinert phone: (515) 294-5223 Department of Mathematics fax: (515) 294-5454 Iowa State University e-mail: keinert at iastate.edu Ames, IA 50011 Return to table of contents
Date: Tue, 4 Feb 92 9:52:15 EST From: gkushmer at Jade.Tufts.EDU Subject: Priming sugar The other day I was going to bottle some Pale Ale I had brewed and went looking for my priming sugar. These days, I have been using pure cane sugar - Confectioners - for the priming (I haven't had any problems with this). Thing is that someone else in the house had used the sugar recently for baking (imagine that) and after rolling the dough in the sugar had put the excess back in the box. Of course, I learned this only once I saw the flaky gingerbread dough rolling in the boil. Needing sugar FAST I went over to the sugar box and pulled out some granulated cane sugar and used that instead. Now I know that both are cane sugar, but does it matter whether I'm using the extra-fine confectioners powder or the granulated stuff?

Date: Tuesday, 4 February 1992 10:16am ET From: joshua.grosse at amail.amdahl.com Subject: To Rinse or Not Volker Stewart (radavfs at ube.ub.umd.edu) asked in #816 about why one should or should not rinse with city water. Fair question, since most of us drink and cook and even brew with it. I don't rinse, because my city water has a small amount of bacteria in it. If I rinse, I run the risk of infecting my beer witn E. Coli or a nitrifying bacteria that might harm the taste of the beer over time. Call your water company, and ask for a water analysis. Along with the mineral balance of the water, which you may find useful, look for bacterial counts. - ----------------------------------------------------------------- Josh Grosse jdg00 at amail.amdahl.com Amdahl Corp. 313-358-4440 Southfield, Michigan Return to table of contents

I have never used it, but I am considering that option for an upcoming party of ours. My questions are: 1. Should I use the standard amount of corn sugar to prime, and then seal the top with a C02 cartridge? 2. How long should I condition the beer in the Roto Keg? 3. How long should I expect the C02 cartridge to last? Thanks a million, Scott Return to table of contents
Date: Tue, 4 Feb 92 09:44 CST From: jws3 at engr.uark.edu (JW Smith) Subject: Oils in "Three Passions Stout" If the recipe works, don't fool with it, right? But I'm curious. Would using straight cocoa powder eliminate the oil problem from the chocolate? I don't know much about chocolate or how it's produced, but it seems that the cocoa powder would cause less trouble than a block of unsweetened chocolate. I'm looking forward to trying this recipe, whichever way I decide to go on this...opinions, anyone? | James W.

It's supposed to be accurate at 60F, and then there is a correction one makes for temperatures that deviate from this. I once saw a chart with this correction as a function of temperature, but I haven't been able to find it since then. Does anyone know how properly to calibrate this instrument? --Jimmy Dee Return to table of contents

Pierce writes: > Guy McConnell mentions a "Monte Sano" blend of coffee that he used to brew a > "mocha-java stout". He sez he chose it cuz its a light blend. Well, actually I said that I used it because it was a mild blend. It also happened to be what I had in the house at the time. While it certainly isn't Peet's "roasted to within an inch of its life", it isn't a light roast either. I would characterize it as a medium roast. I did find out the blend; it is 1/3 Peru, 1/3 Uganda, and 1/3 Santo Domingo (according to the lady I called). > Why not use the real thing. Mocha-Java as in Mocha Mattari (from Yemen) > and Java Estate (from, uh, Java). This is one of the finest and smoothest > coffee blends ever. It can be brewed VERY strong and stay smooth, yet is > very tasty and delicate when brewed medium light. Absolutely. Why not indeed? My recipe was intended to be a starting point for anyone wanting to try this. I named it Mocha-Java Stout because the word "mocha" is often (and quite correctly) used to describe flavoring with chocolate and "java" is a rather widespread (if not universal) reference to coffee in general. It was a chocolate-coffee stout. If there is one thing I would change, it would be to add more Monte Sano or a more assertive coffee to bring out that flavor a bit more. I can barely detect the coffee aroma and taste myself but a friend who doesn't drink coffee said that he could detect it quite plainly. I would probably use Mocha-Java or Sumatra Mandheling if I brewed this again. High quality Java Estate coffee has been rather scarce of late though, making it hard to get a good Mocha-Java blend. > Another side note, dark roasts seem to have a higher oil > content in the brewed coffee than light roasts. As I understand, you > absolutely do NOT want to introduce any kinda oils in brewing as they > oxidise easily (read "rancid!" |~< ) This was one thing that I wanted to test in brewing this beer. I was a little concerned that the oils in the coffee and the chocolate would kill the head but it has a beautiful, creamy head that lasts. As for oxidation, it hasn't a trace of it. I am quite careful in handling my wort to minimize the risk of this anyway. Again, I recommend a brew like this to anyone who enjoys the three flavors as much as I do. - -- Guy McConnell "Drinking homebrew from a wooden cup" Return to table of contents
Date: 04 Feb 92 12:36:22 EST From: Bill Crisafulli <73750.2427 at compuserve.com> Subject: Beer Across America In HBD 814 Bill Dyer described Beer Across America. I posted a message back in December announcing the creation of this little club, so I thought I'd also put in my two cents. BAA is currently trying to work out a national distribution scheme. UPS will deliver within the state of Illinois but refuses to ship out of state. They are using an air service currently to get deliveries to most of the midwest states, but want to cover the whole of "America" ASAP. I'll post when things get settled and let all know. BAA is run by some friends of mine. It is legit, they are handling the beer well and using quality shipping materials. The beer is ordered and delivered directly to their location in IL. They ship it out within a week of their receipt. The last shipment Bill described was their first, and out of 500 shipments only one had any breakage. I agree that it would be great if they could handle additional orders when someone finds a beer they like, but the old freshness problem rears its head. Because the beers they are shipping are not generally available in normal channels, they get a limited supply and thus they do not want to hold any extra. Further on down the road I expect them to offer some limited offerings in this vein, but not right now. I have no direct interest in this operation, other than writing an article in the newsletter about beer. Of course, I am getting compensated for that in liquid form, but other than that this is all their baby! Bill Crisafulli Return to table of contents
Date: Tue, 4 Feb 92 10:35:57 PST From: "John Cotterill" <johnc at hprpcd.rose.hp.com> Subject: Hot & Cold Break Galore Full-Name: "John Cotterill" If anyone doubts the formation of large quantities of break material in their brew, believe it, the stuff is really there! Generally, I brew and ferment in stainless containers so there is no way of seeing whats at the bottom, unless I rack my brew. And with pellet hops and busy yeast, its hard to say what else is at the bottom of any particular vessel. I have just started culturing yeast. As part of this experiment, I needed to make up several batches of sterile starter wort. I did this by first adding some malt extract to some boiling water, adding some hops, and boiling the mixture for about 10 minutes. I then filled some Mason jars with the wort and pressure cooked it for 15 minutes. When I pulled the jars out, there was a good 1/4 to 1/2 inch of break (hot and cold) at the bottom of the jar. I was really surprised at how much stuff there really was! JC Return to table of contents
Date: Tue, 4 Feb 92 09:54:38 PST From: dannet!bruce at uunet.UU.NET (Bruce T. Hill) Subject: Re: EXPLODING KEG This reminds me of an incident that occurred in 1981 (or thereabouts) at a fraternity party. A fraternity at Cal State Univ. Long Beach was having a party and someone unknowingly over-pressurized a beer keg with CO2. The keg exploded and killed one of the partygoers. I believe that this incident forced the keg makers to redesign the kegs so that a pressure relief valve was added. Is this true? Are newer kegs safer than the older ones?

Date: Tue, 4 Feb 1992 11:44 PST From: Fred Condo <CONDOF at CGSVAX.CLAREMONT.EDU> Subject: NA Beer by Boiling; CO2 & EtOH I have tasted beer made non-alcoholic by boiling. The maker of the stuff is highly sensitive to alcohol, and couldn't drink the stuff if her method didn't work. Steve Stroud's comments on the 95:5 alcohol:water distillation product exactly gibes with my faint recollections from college chemistry. It is also why you can't buy liquor higher than 190 proof. Pure ethanol has to be made by means other than distillation. pierce at pyramid.pyramid.com (John R. Pierce) asks about Co2 and ethanol. You seem to be a little unclear here... There isn't a CO2-producing versus an alcohol-producing version of fermentation. Under anaerobic conditions, yeast split each glucose molecule into equal proportions of carbon dioxide and ethanol. Thus, you blow off the CO2 in fermentation, but TRAP the CO2 from your priming sugar by sealing the bottle or keg. For each molecule of CO2 produced in carbonation, you get one of alcohol, so priming does marginally increase the alcohol content of the beer. MARGINALLY.

Date: Tue, 4 Feb 92 15:06:48 GMT From: Conn Copas <C.V.Copas%lut.ac.uk at hplb.hpl.hp.com> Subject: Encouraging diacetyl Al advised that fining and racking towards the end of the primary is one means of encouraging diacetyl, but then asks whether fining earlier in the primary would do any harm. I don't have the answer myself, but have seen wine recipes which advocate adding bentonite whilst pitching the yeast. It always seemed to me that this might inhibit the ferment by preventing yeast circulation, but possibly not. Presumably, botton fermenters would get 'buried' easier than top fermenters ?

Date: Tue, 4 Feb 92 17:27 EST From: CONNOLLY%RISVAX at CCNMR.MIT.EDU Subject: NA brew HBDers: I've run a bit behind the journal but I'd like to comment on the NA thread and thank Steve S. (HBD #816) for hopefully ending this ridiculous discussion. For those of you who claim to be experts on the subject and don't believe that Jack S.'s technique works I'd suggest you check your P. Chem. texts. Mine (Atkins, 1978) gives H2O and ethanol as an example of a binary azeotrope, complete with a phase diagram, saving lots of calculations that can't really be done anyway. The key is to realize that the deviation from Raults Law is due to hydrogen binding between H2O and EtOH. (Atkins, 1978, p. 230) Also, if you check the CRC Handbook of Chemistry and Physics you will look under binary azeotropes and see that the vapor will contain ca. 95% EtOH and ca. 5% H2O. It only makes sense that at this rate you will eventually reach the point where the amount of EtOH in the pot is less then 0.5% and you've got real NA homebrew on your hands! I wouldn't worry about the scientific method and cold fusion in this case Jack...these are experimentally verified facts that have been known for well over a hundred years. Sorry to flame...I've got some useful info out of the Digest but sometimes the misinformation given out by those flaunting their education (I'll refrain) is really irritating. happy brewing pc Return to table of contents
Date: Tue, 4 Feb 1992 15:28 PDT From: Bob Jones <BJONES at NOVA.llnl.gov> Subject: B.A.B.O. & NA Beer from Micah Millsapw I would like to metion that the Bay area brewoff on January 25th went nicely. There were over 150 entries. there also were some great prizes,ribbons ,cash,hops etc. The judges ( myself included) were provided with some great food and beer after the event. In all it was a lot of fun. N\A beer? Can you really do it at home? Early in '91 I wrote an article for the California Celebrator Brewspaper about making N\A at home. When I find the disk that its on I'll post it. It is not to difficult a process, alcohol removal. The efficientcy of stove top evaporation is less than 100 percent but it is something that you can probably live with. It is possible to determine if you have in fact removed some of the alcohol from the beer by checking the specific gravity before and then after heating the beer. The gravity should increase. The process is, after all removing the lightest component of the beer. It is also possible to allow the vapor from the heated beer to condense on a cool surface so the it may be collected. Sensory analysis should verify the presence of ethyl alcohol. A bit of caution, higher temperatures than 180F can boil off the higher alcohols which when concentrated can be toxic. Collecting the distilate is also illegal in the USA. Some commercial N\A is produced by drawing off the alcohol in a vacuum, this works the best but is next to inpos- sible to do at home. Another methode is to use specialy designed yeast strains and mashing techniques to retard or reduce attenuation levels. If there is some interest in the homemaking of non alcohol beers, then I would be willing to post the information and techniques that I've gathered. This may save Jack S. from having to reinvent the wheel. Also my N\As do taste good and tend to be hoppy. Note: low alcohol beers are easier to homebrew than N\As.

Date: Tue, 4 Feb 92 19:42:10 -0600 (CST) From: Brian Capouch <brianc at zeta.saintjoe.EDU> Subject: Re: Millet Beer (sic) In the past few weeks, I've been lucky enough to pick up a couple of books that have changed my life as a brewer. Last Friday, I found a copy of "100 Years of Brewing" in a used bookstore in Chicago. That same day, I believe, there was a wonderful excerpt from that book here on the digest, followed by another post this week. . . . There's a very interesting piece in there about the 1902 technique for brewing "Steam" beer, and if anyone's interested I'll be glad to copy it. The other book is Keith Steinkraus' "Handbook of Indigenous Fermented Foods." It contains chapters on fermentations of many sorts, and the portion of the book that deals with yeast-fermented alcoholic beverages is the longest in the book. Do you know the name of the drink in question? The book contains very explicit directions for the preparation of the various beverages, and I'll look it up and post it if you'd like. I've lined up sources of millet, sorghum, and maize, and will be trying to learn to malt them sometime in the next few weeks. One of my goals is to make some authentic Peruvian-style chicha, about which I've been reading more and more lately. I'm almost certain that's where Charlie P. has gone in search of the "oldest brewers in America." The Winter issue of American Brewer outlines a trip that was taken in search of chicha by a freelance person who was hired by the Schoenling-Hudepohl folks to go down there and see what was shaking. The article contains a lot of interesting things about the beverage, but is so permeated with cultural arrogance and snide remarks about the "filthy" Indians it was depressing to read. The same fellow had an interview last weekend in the Cincinatti paper that I haven't read, but from what I've heard is equally filled with pinhead humor attempted at the native's expense.
