I am going to ferment or 3 weeks rack to secondary and let the bugs do their work.

First time using liquid yeast, was not sure what to expect. Got worried after ferm did not start in a few hours.
However this morning I am bubbling away

Hi Elmer, I think the lag time for liquid yeast is far longer than for dried yeast - at least that has always been my experience. But that said, is that a thermometer near the top of your carboy? I wonder if it would not be more advisable to have that thermometer closer to the body of the liquid. Won't the air above the fermentation be several degrees cooler than the fermenting beer itself?

Ran 3.75# of blackberries (and a few random blueberries) through food processor.
Kept at 160F for 15 min in an attempt to pasteurize.
Added to carboy after racking.
Will age for a few months
