Activity Log

Yeast Starter:

About 24 hours before the brew, boiled 4 ounces of DME in 4 cups of water in a 2 liter flask and let cool. Shook to aerate, pitched yeast, fitted stopper and airlock and placed at 75 f.

Mash/Lauter/Sparge:

Heated 5 gallons of water to 170 f in 10 gallon Polarware kettle with false bottom and stirred in grain. Mashed for 60 minutes. Added boiling water to mash out at 168 f. Sparged with 170 f water capturing 7 gallons of run-off in bucket with easy mash screen. Cleaned Polarware kettle and transferred run-off back into it.

Boil:

Boiled for 90 minutes adding sugar at 60 minutes and hops at 60 and 15 minutes. Cooled with counterflow chiller into 6.5 gallon carboy. Rocked on folded towel for 1 minute to aerate. Pitched yeast, fitted stopper and airlock and placed at 72 f.

Fermentation (target final gravity = 1.018):

Observations of primary stage (20 days at 72 f)

16 hours: 1/2 inch of foam, 33 bubbles per minute
2 days: 1 inch of foam, 72 bubbles per minute

Siphoned to 5 gallon carboy. Filled 2 liter bottle 1/2 full. Pressurized to 30 lbs/sq in and placed in fridge. Took specific gravity reading of 1.020.

Bottling:

Boiled 4.6 ounces of corn sugar in 2 cups of water and let cool. Siphoned from carboy into 2 liter bottle until 4/5 full, squeezed out the air, pressurized to 30 lbs/sq in and placed in fridge. Took specific gravity reading of 1.020 so ABV is approximately 7.7%. Placed sugar water in bottling bucket and siphoned 4.5 gallons from carboy into bucket.
