Notes

Brewed on July 4th, 2022 via BIAB Method

Added 3 grams of CaCl2 (anhydrous), 3 grams of gypsum, and 2 tsp (10 mL) of lactic acid for mash pH and salt adjustments.

Started with 8.5 gallons of water and raised strike temp to 156 degrees F. Mash temp was 152 degrees F and held for 60 minutes.

SG = 8 gallons @ 8.6 Brix (1.034 g/L)
OG = 6.25 gallons @ 11.4 Brix (1.045 g/L)
FG = 5.4 Brix = 1.007 g/L after correction for alcohol.

Fermentation temp ~ 80 degrees F hence high attenuation

Kegged and bottled on 7/17/2022

bottled beer CO2 volumes = 2.7
