Notes

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 with a mashout. Use enough water to have a moderately thick mash (1.5 qts./lb.). Mash in all the grains at 131 °F (55 °C) for 10 minutes, then raise to 143 °F (62 °C) for 45 minutes, then to 158 °F (70 °C) for 15 minutes. Finally raise to 168 °F (76 °C) for 10 minutes to mashout, recirculating. Add the FWH hops to the kettle. Sparge with 168 °F (76 °C) water until 6.5 gallons (25 L) of wort is collected.

Boil the wort for 60 minutes, adding the hops at times indicated in the recipe. Chill to 58 °F (14 °C). Oxygenate, then pitch the yeast. After four days, allow fermentation temperature to rise to no more than 68 °F (20 °C) until fermentation is complete. Rack and lager for at least two months at or below 40 °F (4 °C).
