I pulled a sample last night. Beer is clear, so flocculation is pretty close to complete. My pallet is not accustomed to the taste of diacetyl, so I wouldn't know exactly what it would taste like. The beer tastes pretty good; super malty , so detecting the taste of butter seems difficult. If its tasting good, I guess I can't complain. Cant wait to see how it turns out. I've also heard about doing a second diacetyl rest after bottling.
Carbonate the beer, drop the temp, then bring it back up for a few days for the diacetyl rest before lowering the temp again for aging. Does anyone else recommend this?
