Hello everyone. I was discussing possible effects of smack pack yeast when you break the inner pack but only let it sit a short while before pitching with a brewer friend of mine. I havent actually done this but wonder if there are any real negative effects. I have noticed that the packs say you should let it sit for a few hours but also say that it isnt necessary. Does anyone here have experience with this? Anyone tested it both ways to see if/any difference?
