Step by Step

Crush or grind the grains and place in a muslin or paint strainer bag. Dough-in with 3 qts. (2.8 L) water to target a temperature of 150 °F (66 °C). Hold the mash at 150 °F (66 °C) until enzymatic conversion is complete. Raise the temperature to mash out at 168 °F (76 °C) and hold for 5 minutes. Raise the grain bag out of wort and wash the grains with 168 °F (76 °C) water. Top off your boil kettle to 6 gallons (23 L) and add rice syrup off heat. Stir until syrup is dissolved, then return the kettle to heat and bring to a boil.

Boil the wort 60 minutes, adding hops at times indicated. Chill the wort to 68 °F (20 °C), aerate thoroughly and pitch yeast. Ferment at 68 °F (20 °C) until the yeast drops clear. Rack to a keg and force carbonate or rack to a bottling bucket, add priming sugar, and bottle. Target a carbonation level of 2.4 volumes.
