- Notes:
- The primary mineral composition of the water used in this beer is Ca - 100 ppm, Mg - 2 ppm, Na - 28 ppm, Cl - 107 ppm, and SO4 - 57 ppm. To approximate Stewart's water profile using RO water, add 0.01 oz./gal gypsum, 0.01 oz./gal NaCl, and 0.02 oz./gal CaCl2. With a 1.2 qts/lb water-to-grist ratio, target a mash temperature of 151 F. Perform a single infusion mash for 60 minutes or until proper enzymatic conversion has occurred. Batch or fly sparge with 164 F water to collect 7 gallons of wort in the kettle. Boil for 60 minutes, adding hops and fining agent as indicated. At flameout, rapidly chill the wort to 64 F and transfer to primary fermenter. Aerate thoroughly and pitch plenty of healthy yeast. Ferment at 66 F until terminal gravity of 1.009 is reached, usually within 5-7 days. Rack beer off yeast into a cask/keg for serving targeting 2.3 volumes of CO2 or prime and bottle leaving the bottles at 70-75 F for two weeks to properly condition.
