Steeping went well, temp control with electric bucket is good. Easy to boil over, thought! Must try to insert diode in one of the elements for next time.
|
rehydrated dry yeast while boiling, pitched 1 pkg yeast in 8oz warm water, airlock slowly started to move immediately at start.
|
Malt, hops schedule a bit out of style, using ingredients at hand.
