At LHBS today getting grains for a simple APA. Just going to do an extract brew, throw in some hops, pitch, and plan to bottle in 7 days. (I am out of beer) We were talking yeast and the guy talked about pitching onto a yeast cake of a previous batch, saying it will light up in a couple of hours. Cool I happen to have an Oatmeal Stout fermenting. Was gonna give it another week, but now I am considering bottling in morning, and racking my APA wort on top of the old WYEAST 1335 yeast. I realize the colors dont match, but I am not concerned about that. I wonder what the 1335 will do to my APA? Is this this a bad idea? shoudl I stick to SAFALE 05? But it sounds like fun!
