step by Step
This 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 a step mash. Use enough water to have a moderately thick mash (1.5 qts./lb. or 3.1 L/kg). Mash in the Pilsner, Vienna, and dark Munich malts at 131 °F (55 °C) and hold for 10 minutes. Raise the temperature to 146 °F (63 °C) and hold for 40 minutes. Raise the temperature to 158 °F (70 °C) and hold for 20 minutes.
Begin recirculating, add the Caravienne and Carafa® Special malts, raise the mash temperature to 169 °F (76 °C), and recirculate for 15 minutes.
Boil the wort for 90 minutes, adding hops at the times indicated in the recipe.
Chill the wort to 50 °F (10 °C), pitch the yeast, and ferment until complete. Rack to secondary and lager for 2 months at 32 °F (0 °C).
