Ordered in a couple of smack packs from OBK, one of them I think was already smacked, as the bag had already expanded in the shipping box (can't think it was put in that way, but who knows).
Question is, how long is the yeast viable once the nutrient packs are broken inside? Next brew day was this Sunday, but wasn't planning on doing the batch that the yeast pack that swelled was going to be used for. Would it hurt if it was in the fridge for a couple of weeks?
Has very good dates on it, mfg. in August '14, so practically brand new.
