Notes
Add 500mg potassium metabisulphite to 20 gallons water to remove chlorine/chloramine (as required).
Water treated with brewing salts to: Ca=51, Mg=10, Na=16, Cl=71, S04=71
(Keeping the Cl:S04 ratio even for a balance between malt and bitterness, hitting the minimums on Ca and Mg).
1.5 qt/lb mash thickness. Single infusion mash at 148F for 90 mins. Mashout to 168F.
60-90 min fly sparge with ~6 pH water. Collect 13.9 gallons in boil kettle.
Boil for 60 minutes. Lid on at flameout, start chilling immediately.
Cool wort to 66F and aerate well. Ferment at 66-68F until complete.
Rack to brite tank (secondary), crash chill to near freezing (if possible), add 1 tsp of unflavoured gelatine dissolved in a cup of hot distilled water per 5 gallons of beer, and let clear for 2-3 days.
