Method
On brew day, prepare your ingredients; mill the grains, measure your hops, and prepare your water. Mash in all the grains at 152 °F (67 °C) in 5 gallons (19 L) of water, and hold this temperature for 60 minutes. Raise the temperature by infusion or direct heating to 168 °F (76 °C) to mashout. Recirculate for 15 minutes. Fly sparge with 168 °F (76 °C) water until 6.5 gallons (25 L) of wort is collected.
Boil the wort for 75 minutes, adding the hops at times indicated in the recipe. The first wort hops are added to the kettle just before lautering begins. The 0 minute hops get added right after the heat is turned off. Stir the wort gently and allow to cool to 180 °F (82 °C) then add the hop stand hops. Allow to stand for 20 minutes then chill to 64 °F (18 °C) and rack to the fermenter.
Oxygenate, then pitch the yeast. Start fermentation at 64 °F (18 °C), allowing temperature to rise naturally as fermentation progresses. Mix the dry hops and divide into three equal portions. The first portion gets added after two days of active fermentation. The second portion gets added at the end of fermentation.
The third portion gets added three days after fermentation ends. Allow each dry hop addition to be in contact with the beer for two to three days, then remove.
Rack the beer, prime and bottle condition, or keg and force carbonate to 2.5 volumes. Do not filter or fine the beer.
water profile targets are around 175–200 ppm chloride, 75–100 ppm sulphate, and less than 150 ppm calcium. Depending on your base ion profile, strictly using calcium chloride and calcium sulphate to achieve those targets can result in too high a concentration of calcium, which may affect yeast behaviour, specifically flocculation, so consider magnesium sulphate as an alternative for your sulphate additions.
