The last couple of times I have brewed my unfiltered Oatmeal Stout I have detected diacetyl after it has been on tap for a few weeks. Thankfully the customers dont seem to notice and in fact are asking me to brew it again, but I dont want to brew it again until Im sure diacetyl won't show up. THe fermentations go fine, and the beer is diacetyl free at the time of tapping...I even noticed trace amounts at the tail end of a fruit beer batch. I do not have this problem with any other beer and I don't want to start filtering my stout and lose the body of the beer.
Has anyone had a similar problem? Any info will be greatly appreciated....
Cheers!
Pete
