Okay, I moved my fermenter to my boiler room, which gets pretty warm when the boiler's running, but can go down to 62 degrees, maybe less. After a few hours, SG = 1.022, which may or may not show activity. I stirred up my yeast cake and smeared some on the (inside) side of the fermenter. Hopefully I didn't oxidize the beer too much. If the beer hadn't tasted so bland the other day, I would have bottled as-is. But then again, the sample I tasted was clear - maybe it'll flavor up with some yeast suspension.
How is this Lallemand wheat yeast that came with the kit? Maybe that's the weak link?
