Step by Step

This is a single infusion mash. Mix the crushed grains with 5 gallons (19 L) of 165 °F (74 °C) strike water to stabilize the mash at 153 °F (67 °C). Hold at this temperature for 45 minutes. Vorlauf for 15 minutes then begin sparge. Run off into kettle to achieve volume and pre-boil gravity around 1.049 SG.

Boil for 60 minutes, adding hops and yeast nutrients according the ingredients list. Turn off the heat, give the wort a stir for about a minute to create a whirlpool and let it spin and settle out for 15 minutes before beginning to chill the wort. Cool the wort down to slightly below fermentation temperature, about 65 °F (18 °C).

Aerate the wort with filtered air or pure oxygen and pitch yeast. Ferment at 68 °F (20 °C) for one week or until signs of fermentation have died down. Rack to a secondary vessel and cool beer to 60 °F (16 °C). Condition for an additional two weeks, adding dry hops for the final 10 days of conditioning. Bottle or keg, carbonating to 2.4 volumes of CO2.

0.3 oz. (9 g) Mosaic™ pellet hops (dry hop)
White Labs WLP001 (California Ale), Wyeast 1056 (American Ale), Fermentis Safale US-05 or Lallemand BRY-97 yeast
3/4 cup corn sugar (if priming)

Step by Step

Place crushed grains in a muslin bag and steep in 6 qts. (5.7 L) water at 153 °F (67 °C) for 45 minutes. Remove the grain bag and slowly wash the grains with 1 gallon (3.8 L) hot water. Transfer wort to brew kettle and top off to make 6 gallons (23 L) in your brew kettle. Just before the water reaches boil, remove from heat and stir in the malt extract until all extract is dissolved. Your pre-boil gravity should be around 1.049 SG.

Boil for 60 minutes, adding hops and yeast nutrients according to the schedule above. Once you turn off the heat, give the wort a stir for about a minute to create a whirlpool and let that spin and settle out for about 15 minutes before beginning to chill the wort. Cool the wort down to slightly below fermentation temperature, about 65 °F (18 °C). Aerate the wort with filtered air or pure oxygen and pitch yeast. Follow the remainder of the all-grain recipe (at left).
