Mill the grains, add the mash hops, and mash at 153°F (67°C) for 60 minutes. Raise to 165°F (74°C) for mash out, recirculate until the runnings are clear, then run off into the kettle. Sparge and top up as necessary to get about 6 gallons (23 liters) of wort, depending on your evaporation rate. Boil for 60 minutes, adding hops according to the schedule. After the boil, do a whirlpool step: Stir or recirculate to create a vortex for 10 minutes, then add the whirlpool hops, allowing 30 minutes to steep. Chill to 65°F (18°C), aerate well, and pitch the yeast. Ferment at 68°F (20°C) until complete and gravity has stabilized, then add dry hops for 3–5 days. Crash, remove or rack off sediment, package, and carbonate.

Replace pale ale and pilsner malts with 7 lb (3.2 kg) pale dry malt extract (DME) and replace other grains with 1.1 lb (500 g) dextrin malt, 1.1 lb (500 g) crystal 20, and 8 oz (227 g) crystal 80. Mill the grains and place them in a mesh grain bag. Steep in 1 gallon (3.8 liters) of 153°F (67°C) water for 30 minutes, then raise the temperature to 168°F (76°C). Remove the bag, rinse the grains, add 5 more gallons (19 liters) of water to your kettle, and bring to a boil. Turn off the heat and add the DME in batches, being careful not to scorch. Return the heat and achieve a rolling boil. Boil for 60 minutes, following directions as above.
