    Directions

    This recipe makes 5 gallons and is brewed using a concentrated boil of 3 gallons (11.36 L). If you boil the full volume, you may wish to decrease the 60-minute Target hop addition by 25-33 percent to account for the improved hop utilization of a larger, thinner boil.

    Steep 2-row, crystal malt, chocolate malt and roasted barley at 150°F (66°C) for 30 minutes. Remove specialty grains and add liquid malt extract. Boil for 60 minutes, adding hops at the indicated times and adding the corn sugar and Irish moss 15 minutes before knockout. Chill to 68°F (20°C), pitch yeast and ferment to completion. Bottle with 2/3 cup priming sugar or keg.

    All-Grain Version

    Increase pale 2-row malt to 6 lbs (2.72 kg), decrease corn sugar to 8 oz (227 g) and omit malt extract. Mash grains at 150°F (66°C) for one hour, sparge sufficient volume of wort to result in 5 gallons (18.93 L) after a 1-hour boil, and proceed as above.
