Notes

Brewed on 9/27/20222 via BIAB Method with Connor Cox

Mash water = 6.5 gallons at ~153 F for 60 minutes
SG = 17.5 Brix = 1.072 g/L
OG = 4 gallons of 25.2 Brix = 1.106 g/L

Put wort onto S-33 yeast cake from previous english porter.

On 9/29/22 the gravity was 1.034 g/L.

Final gravity should be close to 10.5% ABV

On October 9th I added a few ounces of medium/dark oak chips that had been soaking in 375 mL of Makers Mark. All oak chips and booze were poured into the stout to age until 11/12/22 when I kegged all 3 gallons to carbonate and age until Christmas.

A few 0.75L bottles will be conditioned as well. Yeast is CBC-1.
