I brewed a Scotch Ale 11 days ago. This was going to be my first brew with properly regulated temperature -- my apartment is very cool in the winter, and I bought a Johnson temp controller and a fermwrap. The setup was working fine, and I was fermenting happily at 66 degrees F. However, when I took a gravity reading yesterday I must have knocked the probe loose (I had it taped to the bucket and insulated with bubble wrap). So the probe was on the floor and picking up the (lower) temperature of the room, which I noticed when I went to rack to secondary today. The fermwrap must have been on for some time. When I racked, the wort was 88 degrees.
My question: how much damage was done? On the one hand, the wort was too hot for a maximum of 24 hours at the end of an 11 day primary. Also, there was no difference in gravity yesterday, before the accident, and today. On the other hand, it was a good 20 degrees over what it should be. What can I expect from here on out?
