Return decoction and rest at 152 F for 15', then raise to 170 F for mash out. Sparge with water, 3 g CaCl2, 1 ml lactic acid, pH 5.5. Cool to 65 F and pitch, 2.5 L slurry restarted with 0.5 L on brew day. Ferment at 50 F.
1/10/22. Note that temp has dropped to mid-40's due to cold snap. Remove from keg fridge and allow temp to rise to 65 F for 24 hours, then place back in garage at 52 F.
