I started 4.5 gallons of pasteurized Empire cider on monday. I pithched the Wyeast product for that purpose. It looked fine yesterday and started to bubble last night.
It was really bubbling away this morning, and when I got back from some errands, it was foaming through the airlock. Also, some doofus had turned the room thermostat to eighty!
I put it in the much cooler laundry room for now and plan to put a freshly sanitized airlock when it settles down.
This is my first batch of cider, BTW. What else should I do?
