I'm a bit worried. It's been 24 hrs with no action at all using 1272 American Ale 2. Being Sunday tommorrow I have no way of buying more yeast. Pitched it into an AIPA at around 22c. It's sitting now at 19c dir to being in the fridge overnight. This is the longest lag time I've had do I leave it for Sunday to see if there is any action over the weekend? What's the max lag time before I should start being worried?
