So I've got a few beers under my belt and I think I'm ready to try something with a higher gravity. I ordered the SN Bigfoot clone from Austin Homebrew and I'd like some tips and hints for my first big beer. I'd like to pitch on top of a yeast cake for this beer, however I've never done that before. Any tips on that or do I literally just pitch on top of the yeast cake from a previously racked carboy? Can the yeast cake come from any size beer with the yeast I want or should I keep it a smaller beer like an APA, brown ale, or something along those lines? Is there anything in specific in the regular brewing process that should be done differently, or emphasized, with a beer this big?
