Just finished brewing an imperial stout and used alot of grain (20+lbs = 5g) that the plan was reuse the grain post mash to make a small stout with a different yeast. This was a week ago, The imperial is doing fine and dandy, slowly chugging along. The small beer (1.04 OG) flocculation seems to have stopped quick like two days in. Understood the majority of the sugars have been used for the imperial. Would it be wise to pitch more yeast or just wait? Has anybody made a second beer from an imperial stout, and how did it turn out?
