This is a multi-step mash. Mill the grains, then mix with 2 gallons (7.6 L) of 154 °F (72 °C) strike water to reach a mash temperature of 144 °F (66 °C). Hold this temperature for 30 minutes. Raise the mash temperature through infusion of boiling water or recirculating system up to 158 °F (70°C). Hold this temperature for 30 minutes.
Due to the very low enzymatic power of this mash, it is recommended to perform an iodine test to confirm starch conversion before beginning to lauter. If iodine test confirms conversion, then you can raise the mash up to mash out at 172 °F (78 °C). If iodine test is negative, continue to hold at 158 °F (70 °C) until iodine test is clear. Vorlauf until your runnings are clear, then begin sparge. Sparge about 2 gallons (7.6 L) of water then top off your kettle to 6.5 gallons (24.6 L).
Boil for 90 minutes, adding hops according to the ingredient list. After the boil, whirlpool for 5 minutes, then let settle for 5 minutes. Chill the wort to about 65 °F (18 °C) and then pitch yeast and aerate wort.
Once fermentation commences, allow beer to free rise up to 70 °F (21 °C). You can hold this temperature for ten days or until the completion of primary fermentation, whichever is later. Bottle or keg the beer and carbonate to approximately 2.3 volumes.
