Single Step Infusion Mash. Makes 5 gallons. Elapsed Time: 4 hours.

  • 11 lbs. Munich Malt
  • 1 lb. Melanoidin Malt
  • 0.25 lb. Chocolate Malt
  • 1 lb. Belgian Aromatic Malt
  • 2 oz. Magnum hops (bittering)
  • 1 oz. Hallertau hops (aroma)
  • 1 package liquid Bavarian Lager yeast - Wyeast #2206 Bavarian Lager

1) Dough In

Set a strike temperature of 122 F. Stir mash thoroughly to ensure even temperature. After dough in, rest at 122 F for 30 minutes.

2) Main Mash Saccharification

Raise to saccharification temperature of 154 F. Hold for 60 minutes.

3) Mash Out

Raise the whole mash to 170 F until saccharification is complete, approximately 20 minutes.

4) Sparging

Slowly sparge the mash, using approximately 7-8 gallons, transfering wort to boil pot.

5) Boil

After sparging, bring the wort to a vigorous boil, stirring occasionally. Inhale.

Boil the wort for 60 minutes, adding ingredients at the following intervals:

Start of boil: Bittering hops- 2.0 oz. Magnum hops

55 minutes: Aroma hops- 1.0 oz. Hallertau hops

60 minutes: Stop boil.

6) Chill

Cool the wort to 80 F or lower before adding yeast. Cool the wort as quickly as possible to prevent infection, preferrably using a one- or two-stage wort chiller. Transfer to primary fermenter and pitch yeast.

7) Fermentation

Transfer wort to primary fermenter. Leave primary fermenter at approximately 70F for 12 hours, then lower temperature to primary fermentation temperature of 54 F. After fermentation subsides, approximately 7 to 10 days later, raise temperature to diacetyl rest temp. of 60 F for one day.

8) Bottling and Lagering

After diacetyl rest, transfer J.S. Bock to secondary for lagering at 40F for 2 months. Then prime and bottle. Age to taste. (Weasel Breweries recommends a minimum of two months. More is often better.)
