Noonan and Miller say commercial pitching rates are .6 to 1.25 fl. oz. per gallon. Five percent sounds more like krausen, which is fermenting wort. Three to six fluid ounces is more yeast than most homebrewers provide, but is a far cry from a quart. Noonan describes various problems associated with overpitching-- though most homebrewers don't overpitch it can be done. > I have one of those BrewCo caps which together with an upside-down > carboy allows collecting the yeast from a primary fermentation.

Hmm. I have one of those. It worked nicely the first two times, but the third time I used it the yeast/trub drain valve leaked and bubbled air into the beer. The beer didn't spoil, but when I noticed this I had real trouble not worrying. I never did repitch drained yeast from this thing because the timing was never right. I like the BrewCap for the following reasons: 1) you can get the last bit of the nasty trub out without racking. 2) you can control how long the beer sits on the yeast, and how much yeast there is in the carboy. This should help in diacytyl reduction. 3) bottling is far easier using gravity directly than through a siphon. I'll probably try to modify the drain mechanism to ensure that it doesn't leak air--obviously I can't tolerate unsterile air getting into my fermenting wort. David Miller's yeast methods (written up in zymurgy last year) work nicely for me. I have had good success reculturing yeast from bottled beer. I also use his method for canning wort to use as a starter. If I can get 2-4 batches from a $4.25 pack of yeast, I'm happy. I don't want to set up a microbiology lab at home. > But the thing I'm still curious about is whether you fellow Homebrew > Digesters ferment your starters out fully before pitching them? Me too. Sometimes I do, sometimes I don't. And what about temperature? I've seen recommendations to use 75 degF in the lager starter, but I'm concerned about shocking the yeast and mutations when adding them to the 50 deg. wort. It seems more reasonable to ferment the starter at the same temperature it will be pitched, or no more that 5 deg higher. --- Happy birthday to me! My wife gave me an old refrigerator. She got it for $2.20 at a sealed bid auction run by the county schools. It works fine, and holds up to 52 degF with no modifications. I asked her why she bid $2.20 instead of two dollars, and she said she wanted to outbid any cheapskate who'd only go $2.00. It's no thing of beauty, but I hope it can help in the creation of some beautiful things. Len Reed ..!gatech!holos0!lbr holos0!lbr at gatech.edu Return to table of contents

I have been too busy to keep up with it on a regular basis, so it is just adding up storage time. Thank you, Chris von Rabenau Return to table of contents
