Has anyone ever tried to mash grain in a microwave with a temperature probe to control the temperature? It sounds like an easy way to do small mashes (<6lb grain?). Just dough it in, toss it in the microwave, and program the power,time, and temperatures? What power levels for heating, maintaining temp? One concern might be uneven heating, but if you stirred it periodically, that would be good, because the hot spots could emulate the effects of a decoction mash, and hence break up the starch globbies? One possible advantage is being able to work with a thick mash troughout, because you wouldn't be adding water as in an infusion mash? Can a mash be too thick?or would maintaining minimum water (as doughed in) be good? I plan to try this, and I'll report the results. Brewuis Ergo Sum. Bill Crick Return to table of contents

Yes!!!!! Maybe as a precaution we should put cattle gratings in front of the doors and make the door openings narrower so those longhorns can't get in!! So, my Coloradan compatriots, we must be united in fighting those who would deprive us! Keep the beer stashes "at home", and, on a side note, don't tell them where the real skiing's at either (keep letting 'em go to Breckenridge..) Yours brewly, Dave.

Date: Fri, 20 Apr 90 12:03:55 EDT From: nolan at lheavx.DNET.NASA.GOV (Tom Nolan) Subject: blowoffs and light extracts I have two comments to add to recent discussions: 1. Not having either a 7-gal carboy or a large diameter blowoff tube, I ferment 4 - 4.5 gallons in a 5-gal carboy. I just fill it to the shoulders of the bottle. I use a bubbler from the start. I don't brew from particularly high-gravity wort (1.040 - 1.050) because I don't like particularly high alcohol. Anyway, the fermentation grows 2-4 inches high but never reaches the bubbler. I don't use a secondary, just bottle after 1 or 2 weeks. This method works great for me, but I'm interested in trying a blowoff to see if I can purify the taste some. 2. I agree with the "light extract only" philosophy. I highly recommend the "Alexander's Sun Country" pale malt extract. It comes in 4-lb cans and it's very light and clean. I then proceed to darken it, even to stout depth, through the addition of various specialty grains and partial mashes. Does anyone have any experience with the extracts that have appeared recently in vacuum-sealed plastic bags? It seems like a good idea from the cost-of-packaging standpoint. - -- Tom Return to table of contents
Date: Fri, 20 Apr 90 09:36:13 -0700 From: cckweiss at castor.ucdavis.edu Subject: chill haze and yeast question FlorianB referred to a particular yeast as "throwing a bodacious chill haze." I've had chill haze problems too, but always figured it was caused by inadequate hot break (excess protein in the wort) or a hop with lots of tannin. Can choice of yeast affect chill haze, and if so, which yeasts are best at minimizing haze?? I've been attacking the problem with Irish Moss, with fair to mixed results. Anyone out there tried this Polyclar stuff? I'm sort of hesitant to mix plastic into my brew, even if it does stay behind with the sludge, but I do like a nice clear lager.

Date: Fri, 20 Apr 90 13:39:52 PDT From: tozz at hpindda.hp.com Subject: Fuller's and diactyl Full-Name: Bob Tausworthe I have fallen in love with Fuller's ESB and London Pride. I have decided to try to brew a Fuller's ESB but am having one problem with the recipe: Fuller's is notorious for its buttery flavor which is produced, i think, by lingering diactyls from the fermentation. How does one get diactyls in their brew? In the past I have always taken steps to eliminate as much diactyl as possible, so actually trying to get diactyls during fermentation has me stumped. Does anybody know of a yeast culture (dry or liquid) which produces diactyls in the final, fermented, product? Should I try to stick the fermentation at a certain point to "fix" diactyl production? Does anybody know how Fuller's brew their beers? Any help would be most helpful bob tausworthe tozz at hpda.hp.com 408-447-2873 Return to table of contents
Date: Fri, 20 Apr 90 19:27:37 EDT From: gt4393c at prism.gatech.edu Subject: Metallic Beer Problem Hey There, Just got through tasting my first batch of homebrew this week. While the overall flavor / smell / color wasn't bad, the beer had a distinctly metallic taste. A friend likened this to "cheap beer that has been sitting in the keg for too long". I'm wondering if anyone has a suggestion as to the cause(s) for this. Some details : I used a 3 1/2 lb can of Edme Superbrew Light hopped malt extract, and 1 lb of corn sugar. I use a 5 gallon carboy for fermentation, and everything else, save for the stainless brewpot, is food-grade plastic. All equipment / bottles were sanitized pretty well throughout the process (save for a slightly-less thorough job during bottling - my siphon kept stopping). I also used the local tap water, but this has, if anything, more of a very light calcium taste to it. Any clues? Could the water actually be causing this problem? Is there a chance that I bought an old batch of extract, and that the tin can "flavored" my beer? Could a bacterial infection cause a "tinny" taste? Could traces of chlorine bleach left over from sanitization cause this? Thanks, -Ivan (gt4393c at hydra.gatech.edu) Return to table of contents

The problem is the pot is made from aluminum. Can I still use it has a brew pot? Also could someone reccomend a liquid yeast for a high gravity Bock (around 1.080-1.090).

Date: Sat, 21 Apr 90 22:34:22 MDT From: roberts%studguppy at LANL.GOV (Doug Roberts) Subject: **WARNING** Don't use Muntona (Munton & Fisson) Ale Yeast This is a follow-on to my message of a few days ago in which I described how my last two dry-hopped batches had turned out extremely cloudy. I was able to narrow the cause down to two possible reasons: 1. The act of dry hopping in the secondary (not very likely) 2. Contaminated yeast Yesterday, I called Byron Burch (Author of "Brewing Quality Beers", and proprietor of Great Fermentations, where I had purchased the Muntona yeast) and indicated my suspicions that the yeast had been contaminated. He told me that there had been problems with wild yeast contamination recently in Muntona ale yeast, and that GF was no longer recommending its use. He was interesting to speak with, and apologetic about my two lost batches. We ended up discussing brewing for about half an hour until I had to go. So: if you have any Muntona yeast, pitch it! But not into your wort. - --Doug ================================================================ Douglas Roberts | Los Alamos National Laboratory |I can resist anything Box 1663, MS F-609 | except temptation.

Date: Fri, 20 Apr 90 16:12:16 PST From: Martin A. Lodahl <hplabs!pbmoss!mal> Subject: Large Carboys The recent discussion of blowoff fermentation reminded me of a question I've been meaning to ask those of you who use large carboys: Where did you get it? I'm talking about a 25-liter acid carboy, or a similar container of around 7 gallons, glass or plastic. What kind of a place (other than a homebrewer's shop) would have such a thing, new or used?
