It's 15 hours since infusion. I'm just going to set freezer stc1000 to 6 degrees C March 26 2016. Decanted beer off starter that was made on March 10th. 3.35 litres spit between carboys. One carboy was at 10.75" fill and the other at 14" fill. put 358grams into one and 404grams into the larger. 47% and 53% wanted to do 43% to 57%. put on fermwrap in freezer ("S" wrap between both carboys) and plugged into heat output of STC 1000. Changed SP to 7C. cleaned 20ga HLT on Mar 26. should not leave wort in there. there was galvanatic corrosion of aluminum pot. ended up with 8.5 Litres trub. That's over 2 gallons. Looks like at least 3 litres of good beer in there so far. I am decanting off the beer for yeast starters. 1.010 FG when putting in to keg
