So...about a week ago I was planning to brew a pumpkin ale, and I picked up one of those smack packs from Wyeast. I smacked it, intending to brew that day or the next...but as it turned out, I didn't find time until about 4 days later.
So the pack sat in the fridge, completely inflated for a few days...then I pitched it into the oxygenated wart and now, 2 days later, there seems to be absolutely no activity at all.
I've got about 6 batches under my belt and i've used the same dry safale us05 dry yeast for all of them so I have no experience with this kinda. Is it time to panic yet? Can I save this by pitching in a dry packet?
