DeTroch are syrupy, sweet, "soda-pop" > beers and do not resemble lambics any more than Bud resembles > Pilsner Urquell. Nope, not DeTroch. I looked at the label again last nite and now I forget but it wasn't DeTroch. The label clearly said "lambic" brewed in Belgium, aged in oak casks, etc. The taste was not sweet, not syrupy at all, very dry and in keeping with the textual descriptions of the style I've read. It was perfect (IMHO) not at all soda pop and consistent with expectations of lambic but no experience of the style. To confirm that it wasn't a fluke I bought another bottle of lambic from a different brewer, this time a peach. It was very different from the strawberry but also very excellent: I'm hooked; Lambics are GREAT!!

The book is on order and I'll try the other variants as much as I can over the winter as I plan/research for brewing a batch of this.

I'll probably be brewing fruit beers anyway as I've had several rasberry wheats and ales that have been really excellent and I've got a recipe for Rasberry Stout that looks real intriguing (Papazian). HOWever, I loved the "acidity and horsey/sweaty Brettanomyces character. " of the limited samples I've tried so far. I've found Jeremy's web page (thanks!) Looks real good, I'm reading it all.

From: layton at sh28.dseg.ti.com (Jim Layton 952-3733) Date: Wed, 2 Oct 1996 08:42:49 -0500 Subject: Am. 2-row, Pils, DMS I use Am. 2-row malt (from Great Western) in most of my ales and I have never experienced flavors that I could attribute to DMS. On the other hand, I've used continental pils malts, from DWC and Durst, in five-or-so batches (a Belg. strong ale, three Munich helles', and 50% in an alt). In each of these cases a pleasant flavor I believe to be due to DMS is present. I can detect this same flavor in many commercial German beers (helles, helles bock, and pils) and therefore I believe it to be appropriate in these styles. My boiling and cooling techniques are consistent (90 min. boil, immersion chill to pitching temp within 45 min). I cannot attribute this flavor to any factor other than the malt. Does this experience match with that of others? Is this flavor, which I can describe as smooth and grain-like but not really "corny", due to DMS? Jim Layton Return to table of contents
From: Michael Caprara <mcaprara at awwarf.com> Date: Wed, 02 Oct 1996 07:45:36 -0600 Subject: Lambics!! I tried to respond to Tom's lambic question via private email, but the message bounced back to me. So... First, I am not an expert on Lambics or how to make them, but I do make them and they are worth the extra cost and hassle. I suggest reading the beer style guideline book called Lambic. Great information and some recipies. I also used a sour mash technique per The Bible to make a Kriek. (BTW, it won 2nd place in the AHA regionals, and the recipe is on my club's homepage.) Go to: http://www.dimensional.com/~godbey/louthan.html My advice is to get a separate racking cane and siphon hose for lambics only. Some of the bacteria cultures that you use can contaminate your plastic. Also, they stink BIG TIME, and you may not want to put a stinky, white mold covered bacteria starter into your lambic, but JUST DO IT! Ferment only in glass and clean thouroughly with bleach before using for a "regular" beer. Finally, let it age, let it age, let it age, and then, let it age some more. Bottle at least 12 or so small bottles and try one a month for a year, take good notes, and you will be amazed at how the lambic changes. Brewfully Deadicated, Michael :{P} MAN! I Love Lambic!

From: Michael Caprara <mcaprara at awwarf.com> Date: Wed, 02 Oct 1996 07:54:45 -0600 Subject: GABF Medal Results There has been some discussion on the judging at the GABF. I personally tried many of the medal winners (except the Coors and Bud!) and I feel that, for the most part, the awards were justified. On Thursday night, I tried all of the Barley Wines and noted that the gold medal would go to either Little Apple Brewing (way to go Jethro!!) or Golden City Brewery (Colorado Rules!) and they took gold and silver respectively. As for the bronze, I felt that Steelhead's Wheat Wine was better than their Old Weasel. In the wheat category, Heavenly Daze's (Colorado Rules!) was by far the best. BUT, I was dissapointed with the medal winners in the Stout category, except for Crusty Butt's Rodeo Stout (Colorado Rules!). Anyway, had to give my $0.02. All of the opinions expressed above are the sole opinion of the author. The author has no affiliation with any of the above mentioned breweries, etc...

From: David Conger <dconger at hal.hscribe.com> Date: Wed, 02 Oct 1996 10:02:16 -0400 Subject: Newbie with whole hops Newbie brewer questions: 1) I'm brewing a beer this weekend that calls for two ounces of Cascades hops and I just happen to have two ounces grown in my own backyard. Obviously I don't know the AA%, but I don't feel that my recipe will be ruined if I'm off by just a few HBU's. Am I safe using these hops for bittering or should I save them for finishing? 2) If I use the aforementioned hops, it will be my first use of whole leaf hops as opposed to hop pellets. I'd be putting them into the standard extract brewer's 1 1/2 gal. boil. What differences in the brewing process can I expect?

GREAT!! Sign me up! Lets see how much, $600?!?!?!? I don't think so. I had to scrape to get my keg system going, there is no way I am going to be able to afford these tanks. Why not modify one of my cornies by adding a cone to the bottom. So, my questions are; What is the ideal angle for the conical part of the uni-tank? Is there a max/min ratio of radius/height for the fermentor? What kind of valve shoud I have on the bottom? What should I do to make sure this thing can handle 40 psi (wide safety margine) when I am done?

From: "Sutton, Bob" <"bob.sutton" at fluordaniel.com> Date: Wed, 02 Oct 1996 08:31:00 -0700 Subject: Airstone Sanitization Jeff Sturman stated: >>>A customer of mine (Mark) recently built an aquarium pump and airstone contraption for aerating his wort, a la Dave Miller's recommendations. He has used it twice and both batches are horribly phenolic. I am quite positive it is an infection problem. Mark makes terrific beer with great consistency so these infected batches have him quite distressed. Dave Miller recommends sanitizing the aquarium airstones but does not recommend a specific technique for doing so. Mark soaked the stones for 24 hours in a dilute bleach solution and then thoroughly rinsed them with boiled water. Is this the preferred method for sanitizing these stones? Is there a better way to sanitize them? Heat sanitation melts the plastic doohickey on the stone. He tried isopropyl alcohol which caused the stone to crumble into dust. Good thing they only cost 50 cents!<<< Jeff, I don't use airstones, however one alternate sanitizing agent would be hydrogen peroxide, available at any drug store. I can't vouch for compatibility with your airstone, but a 30 minute soak should suffice. A less exotic method would involve the use of iodophor. Just make a solution up to the strength required to sanitize bottles, etc. and soak the airstone. See the iodophor label for concentration/exposure time for guidance. Most importantly, the air itself should be free of competing microorganisms. The most positive way to achieve this is to use a 0.2 micron (absolute rating) inline filter (don't forget to sanitize the filter). Some folks bubble the air through hydrogen peroxide or vodka, however this approach is only partially effective, as the sterilant only contacts the wall of the bubble; the air in the bubble is unaffected.

I'd like to get a false bottom for this cooler so that I could use it as a mash/lauter tun when I start doing all-grain brews. Does anybody have a source for such a thing? Or simple directions on how to build one? I'd like to avoid shelling out $60+ for the 10-gallon Gott, just so that I can then go buy the Listermann Phalse Bootom for $16.

From: KennyEddy at aol.com Date: Wed, 2 Oct 1996 11:06:12 -0400 Subject: Low Calcium and Acidic Grains / Steeping Grain Technique & Water Ratios John Wilkinson asks about calcium and dark grians: "That is certainly my understanding of the situation and to expand on it, I hope correctly, isn't it the calcium in the high alkalinity water that reacts with the darker grains to lower the pH? My brewing water is low pH but very low in calcium so I would not expect darker grains to lower the pH too much further. Is this correct? " As was pointed out in HBD2210 by David Burley, roasted grains are acidified due to the production of carboxylic acids during roasting. It's therefore a "direct" addition of acid. The "acidification" of the mash by calcium is due to reactions of the calcium with phosphate compounds in the grain, and is therefore sort of an "indirect" acidification. Two totally separate mechanisms. So the acididy of your dark grains may grant you the happy wort pH that your low-calcium water alone might not. Just like the London brewers, though for the "opposite" reason: their water is high in alkalinity; yours is low in calcium, with the net result being pretty much the same. ***** George De Piro comments on the grain-bag "mashing" technique: " I guess the idea is to convert the starch to sugar, but at the extremely dilute enzyme concentrations that exist in this system, does conversion happen that quickly, if at all? Proteins tend to be less stable in more dilute solutions. I really don't want to go back to the "how fast are enzymes denatured" thread, but I don't want to see a lot of beginners making starchy beer! (I've been there, it sucks) " I've had success with the approach without noticible starchiness. Also, our club's 1995 Brewer of the Year (who's a shoe-in for '96 as well) uses this technique routinely, with apparently excellent results. I would agree that there *is* an effect on conversion due to dilution as George points out, but anecdotal evidence, at least, indicates it's not as much a concern in practice as he suggests. But on the other hand, adding 1/2 lb of grain to four gallons of water probably *will* impede effective conversion, so yes, some clarification needs to be made and a limit really should be placed on the dilution. To be on the safe side, stick with around 1-1/2 quarts water per pound of steeped grains, and let the stuff sit an hour or more or as long as your patience holds out. Also never let the temperature get above 160F and do your best to keep it around 150 - 155. An adequate supply of enzymes is crucial in any case, so add as much pale or wheat malt as you have room in the bag for. The technique used by my friend involves using two pots -- a small "mash" pot and the larger "main" pot. The grain-bag mash takes place in a *small* amount of water (1.3 qt/lb) in the mash pot, and the balance of the (clear) brew water is in the main pot, which is heated to ~170F during the mash period. After conversion, the grain bag is lifted and drained into the mash pot, then he dunks it a couple times in the main pot to rinse and "mash out". Finally, the mash pot is dumped into the main pot and brewing continues. Concern about this technique has been raised before here on the HBD, centering around the release of flour and husks through the grain bag into the brew, which when boiled will cause all kinds of problems like astringency and starch haze. While I certainly can't quantify the results, I'll propose that the small amount of junk released is insufficient to cause noticible damage to the brew. I think my friend's experience and my own testify to that. Perhaps leaving the last couple of ounces of mash water in the mash pot along with the escaped husk and grain particles will eliminate the majority of these "contaminants". ***** Ken Schwartz El Paso, TX KennyEddy at aol.com http://members.aol.com/kennyeddy Return to table of contents

I got this idea from the HBD many moons ago (1994?) and posted on the same topic in HBD 1905 12/7/95 (from which this is excerpted) : > My all grain set up makes use of 2 EasyMashers, one in my mash/lauter > tun the other in my sparge water tank, this setup makes for a very > balanced flow.

Two years with about 15 batches of all-grain, and I am still very happy with the performance of BOTH of my EasyMashers. I have yet to have a hose slip off, and am still free of air leaks (well, my brewing system; not me personally)! And best of all: I DO NOT have to putz around with the EMs while brewing, and I don't need any other parts, fittings, or tools. It just works!

Glenn Colon-Bonet <gcb at hpesgcb.fc.hp.com> writes in #2211: >(prospective members of) the panel ...are asked to submit >a JUDGING resume and 3 letters of recommendation as to their JUDGING >qualifications from people in the industry. This information is reviewed >by the festival staff and the most qualified people are chosen. Maybe you could tell us what is on a judging resume? Are the letters of recommendations written by their employers who would want to claim that they have X number "PPBT judges" at the GABF in their next ad campaign? What makes someone qualified to apply to be a PPBT judge? What percentages of the PPBT people were also part of BJCP at any level? >...numerical score simply states your "favorites" numerically rather >than verbally. It is no more accurate. Personally, I would argue that a numerical score determined at a separate time would be more accurate. Tasting several beers of a specific style simultaneously makes the beer with the greatest sensory impact stand out, regardless of whether or not it is the most true to style. The side by side judging of best of show, you recall, usually involves beers of vastly different styles and I don't think that comparing 1 lager, 1 bock, 1 stout, 1 lambic, and 1 mead, for example, is the same as comparing 5 lagers. >This process *IS* judging. I'll concede that the PPBT method is judging. I'll also point out that the same is often said for the scores given for figure skating or synchronized swimming in the Olympics. >..There is *NO ONE* on the panel that is not qualified to be there. Once again, what are the qualifications that are required? >...The comments I've received indicate that this is one of the >best run competitions in the world. I and my staff take pride.... The vast majority of the HBD understand that running a competition on the scale of the GABF is no small task, and there's a huge amount of work involved to make sure that the event is not a complete fiasco. However, running the judging by finding industry "experts" with nebulous qualifications is bound to make people wonder. People have questioned the qualifications of the PPBT judges and the only responses are assurances that we have a highly qualified panel of specially selected experts. The collective understands technical beer talk - explain to us who the judges are. Not by names, but maybe a breakdown of their occupations as to why these "professionals" are so wonderfully qualified. So, define the word "qualified" for us. We're listening.

I made a 40+% rye beer last year. I cereal mashed the rye and got a perfectly normal lautering rate. If you were going to go up to 60% I guess it would be hard to do a cereal mash however. FYI: in a cereal mash, hard to mash adjuncts are mixed with a small amount of pale malt. This is brought through a mini mashing regimen. I did the Fix 40-60-70 (the 40 rest should help break down the gummy beta glucans). After the 70 rest it is brought to a gentle boil. This is then remashed with the remaining pale malt. - -- Jeremy Bergsman mailto:jeremybb at leland.stanford.edu http://www-leland.stanford.edu/~jeremybb Return to table of contents
From: cwynn at sawyer.ndak.net (Craig Wynn) Date: Wed, 02 Oct 1996 16:20:47 GMT Subject: Racking off yeast scheme I have a mouth wash that comes in a plastic bottle. To dispense a dose you squeeze the bottle and it fills a cup in the mouth of the bottle. I note that some brewers are using plastic carboys for fermentation. If they are like the ones I've seen you should be able to squeeze them like the mouth wash bottle. Suppose you had a plastic tube (like a blowoff tube) except inserted to the bottom of the carboy. I think you then could pump off the sediments! The carboy will draw in air on each pump ( which could be filter through cotton soaked in alcohol). This air would not be mixing with the contents to any significant degree. You could rig up something and flush the air out with CO2. What you'd get is a method for taking the yeast off the beer vs what we do now which getting the beer off the yeast when we move it to a secondary fermenter. craig Return to table of contents

I use citric acid and salt to clean copper mixing bowls. Gets them nice and shiny. You can get citric acid crystals from a winemaking supplies shop. For clean air with an aquarium pump you can get .22 micron syringe filters from Yeast Culture Kit Company. http://oeonline.com/~pbabcock/yckcotbl.html They go in line and seem to provide very little back pressure. They're a couple of bucks, and I'm told you can use them many times if you are careful. I got some white plastic airstones from petco - they seem to work OK. To sanitize put the stone on the tubing, drop it in the iodophor, apply suction to get iodophor into the airstone, and let it sit for a while. Also try the following location for a make your own using aquarium floss; not sterile but will likely do the trick. http://alpha.rollanet.org/~mckay/brew/tips/aeration.html Bob - -------------------------------------------------------------------------- Bob McCowan voice: (508)-922-6000 x208 ATG/Receiver-Protector fax: (508)-922-8914 CPI BMD Formerly Varian CF&RPP e-mail: bob.mccowan at bmd.cpii.com or Beverly, MA 01915 bob.mccowan at cfrp.varian.com - --------------------------------------------------------------------------- Return to table of contents
From: MaltyDog at aol.com Date: Wed, 2 Oct 1996 12:43:20 -0400 Subject: High Gravity Yeasts and Counterpressure Bottling for Imperial Stouts I am preparing to make an Imperial Stout within a couple of weeks, and I have a couple of questions: 1. Has anyone had any experience with making a high gravity beer (should start about 1.104!) with the WYeast Irish Stout Yeast (don't have the number on me)? Can it handle the gravity? Any other ale or stout yeast that anyone has had a particularly good experience with in brewing an Imperial Stout? 2. Recently, I began kegging beer, and carbonating in the keg. Seeing as how an Imperial Stout, and its close cousin, the Barley Wine, both need extreme aging, to smooth out some of the flavors, and add complexity with others, I would assume off the top of my head that it would not be wise to keg an Imperial Stout, let it sit for a while, and then force carbonate it, and counterpressure bottle. I'm thinking that for the beer to reach its full complexity, it would have to be bottle conditioned, with a fresh dose of yeast in the bottle. But am I correct in this assumption? Has anyone out there made either an Imperial Stout or a Barley Wine that was force carbonated, and counterpressure bottled? What was your experience? How long did it take for it to smooth out? I would be very interested in anyone's experiences on these two points. Thanks a lot. Bill Coleman MaltyDog at aol.com Return to table of contents

It must be more difficult than most of us can manage to run such a panel and to try to ensure reasonable results. I'm sure also that the GABF organizers work hard to secure as many qualified judges as they can. The festival is certainly a class act and Glenn and his volunteers deserve a great deal of credit. But, that being the case, it's even more disturbing when serious problems do appear. Two problems that seem obvious this year are: * High number of medals not awarded * Fruit beer category I can understand wanting to withhold awards for beers that are poor examples of a style, or for beers that are flawed, but I have always assumed that the role of a judge should be to find winners, not insult entrants by saying, "None of you are good enough." With the high number of unawarded medals, I think it's fairly clear that too many of the judges have more respect for themselves than for the many hard-working brewers standing behind each beer. The fruit beer category is, I think, a VERY serious problem. There were 83 entries in the category, making it the 2nd largest at the festival. Yet from all those commercially- brewed beers, the judges could not find three medal contenders?? I find it hard to believe. No, I find it impossible to believe. I hate to be overly critical of judges, most of whom work very hard to do a good job. Unfortunately, in a loosely- defined style like fruit beer, judges cannot easily fall back on "oh, they're poor examples of the style" without sounding like fools. Especially when these are *ALL* professionally brewed beers. Especially when there are 83 to choose from. Wow! 83. What *COULD* the judges be thinking??? I've heard that it's the squeeky wheel that gets the grease, but that fruit beer medal being withheld strikes me not as a squeeky wheel but as friggin' fingernails on a chalkboard!

From: Tim Martin <TimM at southwest.cc.nc.us> Date: Wed, 02 Oct 1996 14:22:19 -0300 Subject: air pump question Hey Neighbors, Now that the topic of using air pumps to oxygenate wort has come up again I thought I would jump in with a question. I now have a pump (2.5 amps) from a printing press that I am considering using to oxygenate the wort. I've always had good luck with the ole shake rattle and roll the carboy method. What I don't understand is why do I need to use a filter on the pump? Will the pump not introduce ambient air and germs into the wort just like shaking the carboy will do. I mean I don't filter the air when shaking the carboy so why filter when pumping? And why use an airstone? Well, I do think I understand this a little better, to make the bubbles smaller so they saturate the wort with oxygen quicker. But if the stone are such a pain in the arteries to sanitize and clean from reading other posters, so why not just insert a sanitized hose in the wort and pump away. You can probably tell I've never used this pump yet but I don't intend to ruin a single batch with it because I don't get to brew that often and when I do brew I like to keep it as simple and cheap as a monk would. So what do you think? Thanks, Tim Martin Buzzard's Roost Homebrewery "with that strong predatory taste" Cullowhee, NC. Return to table of contents

This is a good comment. I helped a local brewpub get their entries together. The bottled entries had to arrive about five weeks before the judging. (The kegs for serving had to be ready a couple weeks before that, at least here in Nashville). I brought my counter-pressure bottle filler to the pub and we filled and capped the entries which were Fed. Ex'd the next day. Shipping and bottling is probably a big variable that can't be equalized between breweries. - Bryan grosbl at ctrvax.vanderbilt.edu Nashville, TN Return to table of contents

Proteins tend to be less > stable in more dilute solutions. I've never tried a partial mash - so can't claim any expertice here and am not even sure of the methodology of partial mash brewing. If the p-mash is dilute, then my expectation is also that the enzymes will be less stable, and the catalysis rate slower - and so there is a good possibility of starchy beer. If the partial mash takes place in wort made from extract, then the enzymes will be more stable, but the sugars from the extract will inhibit the enzyme activity (product inhibition). Read - even slower conversion. > I really don't want to go back to the "how fast are enzymes denatured" > thread, but I don't want to see a lot of beginners making starchy > beer!

My long but intermittant interest in extract brewing ended abruptly when I was introduced to all-grain (thanks Mark B.). If an extract brewer was limited to similar extracts that I had access to - then a starchy but flavorful beer would be a step up. I believe starch hazes eventually clear - don't they ?
