I chimed in as a newb (post #60 - 9 packs of notty on-hand, no backup, no local HBS, and was heading into brew day.)
Just reporting back: I proofed per forum advice (thanks RavenChief!) 30 minutes later the 4oz slurry had foamed to almost 8oz in the graduated pyrex (& had that nice bread/yeasty smell.) Pitched last night about 9:45 and 14 hrs later the krausen is starting to rise in the bucket.
This is only my 5th batch using notty (moved from smack packs) but I like the taste in my IPAs. Don't think I'm ready to give up on notty. Will use the remaining 8 packs - proofing as I go and order a few SA-5 both for backup and to compare. Thanks for the guidance all!
