I wanted to brew 5 gallons of a 1.085 doppelbock in late winter and was trying to figure out the best way to build an adequate starter. I may have accidentally stumbled on a good method, but I want verification that this will work.
I was already going to brew a mild in a few weeks, but have decided to brew a small parti-gyle with 4 gallons of mild and 2 gallons of baltic porter. The porter would be ~ 1.070 which would give me plenty of yeast for the doppelbock, but I want to know if there is any danger in pitching a from a fairly high gravity yeast cake. I intentionally kept this on the low end for a Baltic Porter with the hope of not stressing out the yeast, but can go lower if need be.
FYI, I would use WY-2206.
