Preparation

Step 1

Mill the grains and dough-in targeting a mash thickness that will allow your system to achieve the necessary pre-boil volume and gravity. Hold the mash at 154 °F (68 °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 with 170 °F (77 °C) water, collecting wort until the pre-boil kettle volume is around 6.5 gallons (25 L) and the gravity is 1.056 (13.7 °P).

The total boil time is 90 minutes. Add the bittering hops with 60 minutes remaining in the boil. Add the remaining hop addition at 5 minutes. Chill the wort to 67 °F (19 °C) and aerate thoroughly. The proper pitch rate is 2.5 packages of liquid yeast or 1 package of liquid yeast in a 3.1-liter starter. Ferment at 67 °F (19 °C) until the yeast drops clear. 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 2.5 volumes.
