September 26, 2021 - Brew Session
Start, grind grain, heat water to 100° F. (Actual water temp was about 115-120°F). Acid rest at 103°F for 35 minutes (NB- water was too hot to have rest occur at the 96°F I was shooting for, but acceptable range is 86-126°F so not an issue and didn't want to dilute mash).
Add boiling water to reach 133°F Protein Rest for 10 min. Due to mashtun sizing, pulled 66-75% of thickest from protein rest and slowly brought up to 151-155°F for 15 minutes. Raised to boil, boiled for 10 min. At same time as pulled decoction from PR, added boiling water to main mash to reach 142°F Beta Rest.
Added decoction back to main mash to bring main mash to 152°F, rested for 20 minutes. Pulled 75% of thickest mash and brought to boil for 10 minutes. Added back to main mash for mash out of 165°F, let settle for 15 min before sparging
Collected 11 gal @ 14 Brix (1.057). Added 2 gallons water to bring initial volume to 13 gal @ 1.048. Placed on 90 min boil. First hop charge at 60 min, hops according to schedule.
Landed at 1.058. Ferment at 55°F.
