Always check the clock before you begin brewing. Last night I started a new batch of Black Hills Porter and didn’t realize that the time was about 9:45 when I popped the yeast pack. I didn’t get to bed until 2am and I pitched the yeast when it was to hot without realizing it.
The top of the carboy felt really good and so I pitched the yeast. Afterwards I felt the bottom of the carboy and it was quite hot. Just over 100 degrees I’d guess. This afternoon things are going well on the fermentation, but it’s not nearly as quick as it should be going.
Update: On 12/31 the beer was racked to a secondary carboy as most visual action inside the carboy has ceased.
