Mill grains and dough-in using RO water until a medium thickness mash is achieved. Treat mash with 1 tsp calcium chloride. Hold mash at 152 °F (67 °C) until conversion is complete. Sparge slowly with 170 °F (77 °C) RO water treated with 2 tsp phosphoric acid, collecting 6 gallons (22.7 L). Bring wort to a boil.
-- 5.3-5.4 pH for mash @ room temp
-- Less than 6.0 pH for sparge
--Boil pH of 5.1
After the hot break, add the first charge of bittering hops. Boil for 60 additional minutes, adding the other hops per the hopping schedule. Allow the wort to rest for 5 minutes, then chill rapidly to 65 °F (18 °C). Rack to fermenter, leaving break material behind. Oxygenate, pitch the yeast, and ferment at 68 °F (20 °C). Fermentation should be done in less than a week, but don't rush it.
After the yeast has mostly settled, prepare a secondary fermenter (carboy). Blow in some CO2 to displace any oxygen, add the dry hops and rack the fermented beer on top of the dry hops, minimizing splashing. Leave the beer in contact with the hops for a week.
Rack to a keg and force carbonate, or rack to a bottling bucket, add priming sugar and bottle. Target a carbonation level of 2 to 2.5 volumes.
Variation: Add 0.5 lb (0.45 kg) Orange Blossom honey in the last 15 min of the boil.
