I brew 15 gallon batches.
Last week I made a starter using harvested yeast. I then let that starter sit for two full days in the refrigerator after fermenting out.
I brewed my batch and felt it was too warm to pitch the yeast at 6PM. So I let the conical sit in a 45F garage until the next day. I pitched the yeast.
Then, the next morning I opened up the conical and found no activity to be seen. I closed it up and went shopping for the day. Came back and found it chugging along.
My point? Sometimes we home brewers get to excited about stuff. It turns into beer. I will be drinking mine in a month or two. So will you. Enjoy.
