Krausen is no longer being pushed through the air lock. New air lock this morning and clean the beer from the top of the carboy to prevent mold growth.
Thermometer I was using went wonky. Touching it made it go wild. Thermoworks Dot shows a temperature of 64°. Wanted to avoid elevated levels of esters since this is a stout but I seem to get a little banana through the air lock. Hope my nose is wrong. May bring it up to 65° tomorrow.
