All Grain Brewing / Consistent problems with Diacetyl
« on: July 06, 2010, 07:58:10 PM »
I've been all grain brewing for 9 months now and have noticed a consistent problem with my beer having Diacetyl. Actually, I extract brewed for many years before moving to all grain, but I never noticed a problem before with Diacetyl. I must admit though, that at the same time I started all grain, I also started to learn more about off flavors in beer and started paying more attention to things like Diacetyl and Acetaldehyde, so they may very well have been there before, but I wasn't skilled enough to notice them. Anyhow, back to my question. What could be causing my consistent problems with Diacetyl? Another thing I've noticed is that I don't always notice Diacetyl in the beer initially, but often times as a keg ages on me, the flavor comes out. Any ideas or suggestions on what I can do to eliminate this from my beer? Other than this problem, my beers have been pretty good.
