DIRECTIONS
Mill the grains and mash at 150°F (66°C) for 60 minutes, then run off into the kettle. Sparge and top up as necessary to get about 6.5 gallons (25 liters)—or more, depending on your evaporation rate. Add dextrose and boil 60 minutes, adding hops according to the schedule. After the boil, conduct a whirlpool step: Stir to create a vortex, cool to 180°F (82°C), add the whirlpool hops, and allow 30 minutes to settle. Chill to 70°F (21°C), aerate well, and pitch plenty of healthy yeast. Ferment at 72°F (22°C). When fermentation is complete, crash to 35°F (2°C), rack off the trub and onto the dry hops in a purged vessel. After 1 day, rack into a keg or bottling bucket, adding hop terpenes pre-blended with 5 ml of Everclear once about a quarter of the beer has been transferred. Package immediately and carbonate to about 2.2 volumes.
