Step by Step
Mash grains at 160 °F (71 °C). Mash out, vorlauf, and then sparge at 170 °F (77 °C) to collect enough wort to result in 5 gallons (19 L) after a 90-minute boil. Boil for 90 minutes, adding ingredients as indicated in the ingredient list. After the boil, let the wort sit for 15 minutes before cooling. Ferment at 70 °F (21 °C). When fermentation slows, add dry hops for five to seven days. Bottle or keg as usual.

Partial mash option: Reduce the 2-row pale malt in the all-grain recipe to 1 lb. (0.45 kg) and add 4.5 lbs. (2 kg) light dried malt extract. Steep crushed grains in 1 gallon (3.8 L) of water at 160 °F (71 °C) for 45 minutes. Remove grain bag and rinse with at least 2 gallons (8 L) hot water over your brew pot. Boil for 60 minutes. Follow the remaining portion of the all-grain recipe.
