we brewed a Russian Imperial Stout on Friday.
Fermentation started on Saturday, it stopped last night.
The yeast we used was a Sarfale S-04 with a temperature range from 64-75 degrees.
The ambient temperature of the basement is 60, along with the fementer temp.
Is it possible that the yeast has gone to sleep?
Can we bring the temp back up to restart fermentation or is it over?
