 General Instructions Mass Temp and Sparging<br />

Mill the grains and dough-in targeting a mash of around 1.5 quarts of water to 1 pound of grain (a liquor-to-grist ratio of about 3:1 by weight) and a temperature of 152 °F (67 °C). Hold the mash at 152 °F (67 °C) until enzymatic conversion is complete. Infuse the mash with near boiling water while stirring or with a recirculating mash system raise the temperature to mash out at 168 °F (76 °C). Sparge slowly with 170 °F (77 °C) water, collecting wort until the pre-boil kettle volume is around 5.9 gallons (22.3 L) and the gravity is 1.044 (10.9 °P).

Once the wort is boiling, add the bittering hops. The total wort boil time is 60 minutes after adding the bittering hops. With 15 minutes left add the Irish moss or other kettle finings and at five minutes left add the last hop addition. Chill the wort to 68 °F (20 °C) and aerate thoroughly. The proper pitch rate is 9 grams of properly rehydrated dry yeast or two packages of liquid yeast.

Ferment around 68 °F (20 °C) until the yeast drops clear. With healthy yeast, fermentation should be complete in a week or less. Allow the lees to settle and the brew to mature without pressure for another two days after fermentation appears finished.

Rack to a keg and force carbonate or rack to a bottling bucket, add priming sugar, and bottle. Target a carbonation level of 1 to 2 volumes depending on your packaging. Serve the finished beer at 50 to 55 °F (10 to 13 °C).
