I would hesitate to apply the adjective "good", myself -- I thought it was perhaps the most misleading and contradictory portion of a sloppy, confused book. Rajotte's sugar information is *not* especially reliable. In respect to dark candi sugar, I would second Phil Seitz's note that -- once again, in despite of the AHA and Rajotte -- you should not expect a color contribution of any significance. I believe that the dark sugar *does* provide a specific flavor contribution, although it may be slight, but haven't had the opportunity to do a control. I think that sensitive, judicious use of Belgian caramel malts (and especially Special B) is far more critical. I say "Hooray" for sugar in beer, when properly used, but some of the homebrew "information" is suspect. - --Jeff ------------------------------ Date: Tue, 1 Mar 1994 08:07:41 -0700 From: berg%eccx.dnet at esu36.ateng.az.Honeywell.COM (DAVID BERG) Subject: yeast culturing Hey all- Last night I cracked open a bottle of Liefman's Goudenband. After polishing that off (it was a magnum) I decided to attempt to culture the yeast. I used some wort I had canned in this attempt. My question is: is the yeast contained in the bottle viable (assuming it's not dead) and will it be usable, or is it just yeast they pitch for bottling? Next question: where is everyone getting their cultures of pedio and brett? I have a friend who lives in Ann Arbor who informed me that GW Kent has closed their door to walk in customers and is strictly a distributor now. I doubt they would be willing to send me 1 or 2 cultures ;^) It seems every reference I read alludes to getting the yeast from Mike!

As many of you know, I'm always willing to give away opinions!!! ;-) How did that guy who grows his own ingredients innoculate? My guess is that it is only really reasonable to do in the cooler months of a temperate zone. say oct...march or april. Since the real lambic brewers do not brew in summer, my guess would be that a spontaneous innoculation in a warm region like so cal would be asking for some nasty brew. (I am not worrying about toxins for this discussion) I have a half gallon of brown ale wort which spontaneously fermemnted. I haven't tasted it, but i will. It was most likely innoculated by bugs in my basement and/or fridge. The story is that I had saved some wort for starters in the fridge. I used some, and forgot to put the unused portion back. It fermented. aaron ------------------------------ Date: Tue, 01 Mar 1994 12:18:41 -0400 From: Ed Hitchcock Subject: Art, science, and Lambic brewing In the continuing battle of wits (nitwits?) Jim Liddil parried my thrust as follows: >I guess I was not being direct enough about not the humor here :-) But again >lambic is not the normal ale or lager. And many belgian lambic brewers don't >care about the processes and how thye apply. They just cool the owrt overnight >in open coll ships and pump it into wood casks Tell that to Frank Boon. Brewing a Lambic (as opposed to a pLambic) requires lots of special knowledge, because there are so many variables. >My point was not to suggest adding enterics directly but to let them come from >the air by cooling the wort overnight. What beginner has not stuck his arm >into the wort or used old bacteria laden yeast. Granted these bacteria survive >in normal beer but not for long in lambic. If cooling overnight is so >dangerous how come more belgians aren't dead or sick. After having had a >number of Cantillons lately I don't believe Van Roy practices any >sanitation >:-) My point was that the "order" of fermentation of lambics is not necessarily obeyed by the critters in your kitchen. According to Guinard, the enterics (and, btw, E. coli is not one of the enterics listed by Guinard) take over first, and are subdued by the yeasts. In a batch I brewed last spring the enterics took over, but were not only not inhibited by the yeast, they actually kept growing to the extent that there was a SECOND KRAEUSEN from bacterial activity weeks after the yeast had gone dormant. >In your brewery. Have you done ap-lambic and check it for enteric bacteria >after it has been in femrnetaiton and the bottle for two years? No. But enterics should disappear entirely long before it goes into the bottle. >% You don't need pathogenic bacteria to be alive to a) ruin your >% beer, b) poison you. Think botulism... > >We are not talking about regular beer. This is p-lambic it is naturally >infected and some people would already say it is ruined :-). I am not an >expert but has boutlism ever been found in beer. I was making an example. To elaborate, botulism is a toxin produced by bacteria. The bacteria need not be present for the food to kill you. That's why you can get botulism from cooked food. The moral being that faith in the "Nothing pathogenic can live in beer" does not guarrantee that something yucky can easily spoil your p-Lambic. A good Hafnia infestation, if allowed to survive too long will take your DMS levels through the roof. > ...Again how had lambic been >brewed for so long and it is not killing people? But I bet there have been hundreds of bad batches! > ...I still fail to see how >cooling the wort naturally can cause a problem or is the air inherently >different in Payottenland vs Tucson, AZ. Well, it is but from an infection >pathogenic standpoint I would venture to guess it is not. Then again maybe >some valley fever cocci might get in my beer. But it would not survive >since I already asked. Aha. The microflora in your kitchen/backyard are immensely different from those in the attic of a lambic brewery. Your kitchen is full of not only enteric and other vbacteria, but Penicilium spores and scores of other moulds and weird things. The attics of Lambic breweries have been selectively breeding certain bacteria (and bats) for generations. >But the belgain lambic brewers seem to have the attitude that one cools the >wort and puts it into casks and let htings happen. Works for them. So I still >feel that natural inncoluation is worth trying and something not to worry >about. :-) It is worth trying. It has been tried before, and will be again. I feel though that it IS something to worry about, and if one is truly serious about making a decent p-Lambic, they should read up and understand what they are doing. You have obviously done your homework, except I still stick to my original comment which was that E. coli in your wort should not be taken with a cavalier attitude. This is not because it may show up in the finnished product after two years in the bottle. It may not only produce off-flavours, but may survive long enough in the fermenting wort to cause serious illness if a sample is taken at say, 2-3 months. There are a gazillion strains of E. coli, and some are very unpleasant indeed. ____________ Ed Hitchcock ech at ac.dal.ca | Oxymoron: Draft beer in bottles. | Anatomy & Neurobiology | Pleonasm: Draft beer on tap. | Dalhousie University, Halifax |___________________________________| ------------------------------ End of Lambic Digest ************************ -------
