Date: Tue Jul 3 23:37:18 1990 From: doc at crash.cts.com (Mitch Evans) Subject: Infection or Paranoia? Howdy! I've been getting the digest for about the last month, and thought I would voice a question or two to the folks out there "in the know". I get an ugly brown residue along the wort/air boundary during my initial fermentation. I have been assuming that this is yeast, or some other related (read non-nasty) product of the fermentation process. BUT, with all of the sanitation articles floating around, I have begun to worry. I take very intricate precautions with sanitation, and would hate to think I have been allowing mold or other critters into my beer for the past two years ;) My second question has to do with spreading the Homebrew Digest around. I have given it away to friends, and the folks at the local homebrew supply shop (Beer and Wine Crafts in El Cajon, CA). Does anyone mind? I would like to take some copies to the next QUAFF (QUality Ale and Fermentation Fraternity) meeting. I just joined, and found that I had something to contribute (if allowed) to a crowd a bit more experienced than I.

The reason that you wouldn't want to ferment in your kettle is that if you get good hot and cold breaks, you will have a fair amount of trub. You would want to get the brew off the trub before fermenting. >I was also thinking that you could use some stainless >piping for a wort cooler. You'd add the piping during the boil, have both ends >of the piping come through the large stopper, and then circulate water through >the piping to cool the wort. I initially thought this wouldn't work because you couldn't fit the spiral tubing through the hole, but if you did a downward spiral and then doubled the piping back up the same spiral, maybe you could "screw" the chiller into the hole. Also, the cost of stainless would probably be prohibitive -- I suggest copper tubing. In any case, getting the wort off the trub would make this setup unpractical. Mike Charlton writes: >we have had alot of trouble with fusel alcohol Charlie Papazian says "fusel oils." I don't know which is correct. >He suggests in his book to let the wort sit overnight and then >rack off the trub before you pitch the yeast. He maintains that since the >wort is below 80 degrees F, contamination is not a real problem. I've seen several references to Miller's book and was shocked. I don't know if he's been misquoted or Miller himself is misguided. I don't have his book (maybe I should get it and see for myself. Here's a perfect example. I can tell you without a doubt that when the wort is below 180 degrees F, contamination should be your primary problem. Don't worry, just be careful to not allow airborne nasties or nasties living in your wooden spoon, on your hands, in your mouth, etc. touch your beer. I believe that Miller may have said that since the wort is below 80 degrees F, that OXIDATION is not a problem. Big difference. Relax, don't worry, be sanitary. Al. Return to table of contents

It seems like a minor point, but I have never seen it mentioned: If one wishes to aerate the wort when pitching yeast, and have it mixed well too, wouldn't the ideal method be to pour the starter into the fermenter first, then rack the wort in on top of it in a splashy manner? Thanks...Gary P.S. I wish I'd heard (or thought) about kegs before I went out and bought my SS brewpot 8'(. Return to table of contents

He maintains that since the >wort is below 80 degrees F, contamination is not a real problem. Assuming you thought (and I thought) that you were paraphrasing Miller's book "The Complete Handbook of Homebrewing": Wow; This sets some kind of record for distortion. Hopefuly Miller wouldn't mind the following quote from page 149 to clear this up and head off misfortune: "At this point you have two choices, depending on how cold your wort is. If it is down to fermentation temperature (48 to 55F for lagers, 60 to 65F for ales) you should pitch your yeast immediately. If you have got the wort down to near the freezing point, you can pitch the following morning, after the wort has come up to fermentation temperature. Either way, close the fermenter and move it to your fermentation area. The wort should be racked off into a second fermenter about 8 to 12 hours later, to separate it from most of the hot and cold break material which will settle at the bottom of the vessel. Also remember that, before pitching, the wort must be thoroughly aerated." > We decided >to pitch the yeast immediately (more for time reasons than for worrying) so >we were not able to rack off the trub. I have two questions (finally). Why not? While the break is settling the yeast have gone into suspension in the wort. It is not hiding out in the break, so racking the wort after letting the break settle is not going to somehow leave the yeast behind. >Despite the fact that we were unable to rack off the trub, will using a >wort chiller result in lower production of fusel alcohol? Secondly, we used I doubt it but it sure won't hurt the beer if properly used. >WYeast American Ale yeast for the first time (as opposed to the Doric and >Red Star that we were forced to use before). Will the use of this better >yeast culture reduce the amount of fusel alcohol. Note that I'm NOT worrying; The combination of a good yeast and (especially) lower fermentation temperatures should help. - -------------- Pete Soper (soper at encore.com) +1 919 481 3730 Encore Computer Corp, 901 Kildaire Farm Rd, bldg D, Cary, NC 27511 USA Return to table of contents
