Subject: Big Brewer Blowoff??
Date: 1989-01-20 14:53:00 GMT
I agree with the thinking of many with regard to the blowoff method of
fermentation. The foam and resins which cover the top of the primary
ferment are FOUL! Separating it from beer has to be good. Blowoff
seems to be the only way of getting the crud off the beer without
contaiminating the fermenting beer.
What do the big brewers do? I don't recall A-B using hoses and scaled-up
gallon jugs to collect their blowoff. Presumably, they use a closed
fermentation system, with the resins falling back into the wort. In spite
of this, the big national brands have none of the fusel alcohols or other
tastes often associated with the krausen foam. The national brands are so
bland that any problems associated with unseparated resins would be
immediately obvious in the taste.
I must conclude that either a) the unseparated krausen foam does NOT detract
from the taste or the beer, or b) there are other ways of separating the
wort from the bitter resins. Any comments?
