Notes

Brewed on 7/31/2021 via BIAB Method

8.5 gallons Strike Temp = 157 degrees F
Mash Temp = 152 degrees F for 60 minutes

Both Pilsner and Minute Rice were milled before mash.

SG = Brix = 9.3 = 1.037 g/L
OG = Brix = 11.9 = 1.048 g/L
hydrometer = 1.049 g/L after correction

Temp = 88 degrees F. Put in fridge and cooled down to 65 before pitching yeast (S-23). Fermented at 54 degrees F.

On day 9 (Aug 9), both refractometer and hydrometer read 1.013 g/L. I kept it fermenting at 60-62 degrees F.

On day 14, gravity was still 1.013 g/L so I kegged it on 8/14/21. Very weird why the yeast did not attenuate more especially since mash temp was 152 F. Might try 148 F next time.

3 gallons were kegged with ~0.5 tsp gelatin. 2 gallons were bottled with 1.7 ounces of corn sugar (dextrose).
