his recipe uses reverse osmosis (RO) water. Adjust all brewing water to a pH of 5.5 using phosphoric acid. Add 1 tsp. of calcium chloride to the mash.
This recipe uses an infusion mash. Use enough water to have a moderately thick mash (1.5 qts./lb. or 3.1 L/kg). Mash in the mild malt and flaked grains at 151 °F (66 °C) and hold for 60 minutes. Begin recirculating, add the dark grains and crystal malt, then raise the mash temperature to 169 °F (76 °C) for mashout. Continue to recirculate for 15 minutes.
Sparge slowly and collect 7 gallons (26.5 L) of wort in the brew kettle. Bring wort to a boil.
Boil the wort for 90 minutes, adding hops at the times indicated.
Chill the wort to 68 °F (20 °C), pitch the yeast, and ferment at this temperature until complete. Allow the beer to settle for at least one week to give the beer time to clear. Consider adding a fining agent or lagering if haze is slow to clear.
Rack the beer, prime and bottle condition, or keg and force carbonate to 2.4 v/v.
