Mill the grains and dough in at 99°F (37°C). Via infusion or direct heat, raise the temperature to 126°F (52°C) and rest 5 minutes. Pull about one-third of the mash for a decoction: Raise this portion to 145°F (63°C), rest 5 minutes; raise the temperature to 162°F (72°C), rest 15 minutes; then bring to a boil, and boil for 15 minutes. Reunite the decoction with the main mash and mix, to bring the full mash temperature to about 144°F (62°C). Again, take about one-third of the mash for a second decoction: Raise this portion to 162°F (72°C), rest 15 minutes; then bring to a boil, and boil for 15 minutes. Reunite the decoction with the main mash and mix, to bring the full mash temperature to about 165°F (74°C); rest 10 minutes.

Do a vorlauf step until your runnings are clear, then run off into the kettle and add the first-wort hops. Sparge and top up as necessary to get about 6.5 gallons (25 liters) of wort, depending on your evaporation rate. Boil for 90 minutes, adding hops according to the schedule. After the boil, chill to about 46°F (8°C), aerate well, and pitch plenty of healthy yeast. Ferment at about 50°F (10°C) for 10 days, then drop to 37°F (3°C) and lager for at least 4 weeks.
