DIRECTIONS

Prepare a 4-liter (4-quart) starter or, better yet, pitch this beastly wort directly onto the yeast cake from a Helles or standard Bock.

Mash Schedule

• A 10-minute protein rest at 122°F (50°C)
• A 30-minute beta amylase rest at 149°F (65°C)
• A 30-minute alpha amylase rest at 160°F (71°C)
• Mash out: A 10-minute rest at 170°F (77°C)

Boil for 120 minutes. Ferment for 10 days at 50°F (10°C) or until the specific gravity reaches 1.035. Perform a diacetyl rest at 60°F (16°C) until the final gravity is reached (2–4 days). Rack to a lagering vessel (carboy or keg) and gradually lower the temperature to 38°F (3°C) and lager at 38°F (3°C) for at least 4 months. If bottling, additional fresh yeast in the bottling bucket is essential to support carbonation.
