I received an order recently in which a Wyeast smack pack of 1056 was already fully inflated. I figured it had gotten “smacked” when someone dropped the box. Anyway, I threw it in the fridge intending to try creating a starter with it. I wasn’t too hopeful, the icepacks and the yeast packs were warm on arrival.
But last night I made a starter wort w/ 130g DME and 1300ml water. Took the yeast out of the fridge for a few hours and pitched at 60F wort temp. The little nutrient pouch was tight as a drum and clearly had not been “smacked”! 4 hours later it began to fiz like crazy when shook a bit.
So far it doesn’t smell off or anything. Should I use this for a batch of beer?
