---------------------------------------------------------------------- Date: 7 Feb 90 01:53:39 MST (Wed) From: hplabs!gatech!raven!rcd (Dick Dunn) Subject: off-color beer About St Paddy's Day...I once brewed up a batch for a party. I started off intending to produce just some green beer, but then I thought "what the hell; I'll make various colors just to twist people's heads." The idea was that I brewed a basic light-amber ale, then added normal food coloring at bottling. Two cautions: First, remember you're adding color to something that's at least yellow to start. If you want beer that's really green, not bile- colored, use a combination of blue and green coloring. Second, you'll find that it takes a lot of color because some of the color seems to precipitate out. (It appears to attach to the yeast...you'll want to have more than the usual care not to dump out the sediment, which is *really* disgusting!) I was able to mark the labels with my usual batch numbering modified so I could tell (even in a not-entirely-sober state) what color was intended: I used the batch number and the expected transmission wavelength in 10's of nm...instead of batch number 39, I had number 3963, 3958, 3947... Folks got some entertainment out of trying to guess what it meant, and it was fun to open and decant the initial group of bottles. ("Well, what do you suppose this one will look like?!?" It all tasted the same, of course.) - --- Dick Dunn {ncar;ico;stcvax}!raven!rcd (303)494-0965 or rcd at raven.uucp Return to table of contents

My Hydrometer is calibrated at 65% F, but I often take readings at 75-90% (I hate waiting). I know there must be a simple formula to interpolate what the sg at 65 would be given a sg at, say, 75?

Pete is correct to warn everyone about tannins. The whole point of straining the grains out just *before* the boil is to avoid leaching tannins into the wort. Much of the variability available to the extract brewer comes from adjunct grains; not only toasted malt, but chocolate, black patent, roasted barley, etc. All of these introduce husk material into the wort in the same way. Success is just a matter of sufficiently straining the wort just before the boil starts. Putting the grains in hop bags works ok. Since I have several brewing pots, I pour the whole wort into another pot through a coarse mesh strainer, then back again through a very fine mesh. You could obviously carry this to whatever extreme you need in order to not worry. It would be a real pity for brewers to be scared away from the creative use of these adjuncts, since they present such a great opportunity for experimentation and great taste. If any of you have worries about this, please (re-)read Papazian's book and relax. wa ps. grains actually do make very nice teas, try it sometime... Return to table of contents

Date: Tue, 6 Feb 90 21:07:14 -0800 From: hplabs!garth!apd!phipps (Clay Phipps) Subject: Deep Red Color My ideas for my "line" of homebrew include a top-of-the-line brew (a "festbier", perhaps ?) that has a deep red color like that of wet brick (I suppose that I can accept its unfortunate resemblance to FSU garnet :-). The commercial "red" brews that I have found at microbreweries (e.g.: Winchester Brewing's "red ale") or my local liquor emporia are really just a deep amber, not "red" in any sense (except perhaps by comparison with "golden" brews). I know that the color is possible, because "Celebrator" bock (the one that comes with the white plastic rampant ram trinket; by Ayinger, I think) has a color very close to what I want. I've consulted _How To Brew Beers Like Those You Buy_, but it's not one of those covered. Just duplicating "Celebrator"'s color would allow me to "stop worrying". Starting with 7 pounds of Lodi Light malt extract for a 5-gallon batch, I've tried adding up to 2 *pounds* of light (?--no Lovibond information) crystal malt (removed before boiling), but that gives me an amber color. Nice, but not what I'm after. The brew I now have in my 5-gal. primary has 1 pound of "dark" crystal (I forgot to ask about degrees Lovibond where I bought it). I'm not convinced that this will do the job. I've heard that Munich malt is the answer, but even light crystal malt seems physically much darker than Munich malt. I thought Papazian wrote that Munich malt had to be partially mashed before it could be used. I'm trying for something like a red Liberty Ale, rather than a porter, so I really don't want any of the "roasted" character of the really dark grains. That criterion probably precludes starting with a dark malt extract, too. Small amounts (1/8 pound ?) of the dark malts (I'll have to consult my records to identify what I used) just seem to get me shades of brown. Is at-home "toasting" of crystal malt in my kitchen oven the solution ? Return to table of contents
