It's a sickness!
I have an Imperial IPA that was on a wlp007 cake and racked that off to a secondary, then I put a red ale ontop of the cake. That was 12 hours ago and still no fermenting action . I thought the cake would start right away as their is more yeast than if I pitched a vial? Should I be worried? Should I pitch a vial in if no action?
