This is a single step infusion mash using 10.5 lbs. (4.8 kg) of 2-row pale malt. Mix the crushed grains with 4.0 gallons (16 L) of 161 °F (72 °C) water to stabilize at 150 °F (66 °C) for 60 minutes. Sparge slowly with 170 °F (77 °C) water. Collect approximately 6.5 gallons (25 L) of wort runoff to boil for 75 minutes. The 75-minute Warrior hop addition is 0.8 oz. (23 g) (12.8 AAU) to allow for the higher utilization factor of a full-wort boil.
While boiling, add the hops, Irish moss and yeast nutrient as per the schedule. During the boil, use this time to thoroughly sanitize a fermenter. Now add the wort to 2.0 gallons (7.6 L) of cold water in the sanitized fermenter and top off with cold water up to 5.0 gallons (19 L).
Cool the wort to 75 °F (24 °C). Pitch your yeast and aerate the wort heavily. Allow the beer to cool to 68 °F (20 °C). Hold at that temperature until fermentation is complete. Transfer to a carboy, avoiding any splashing to prevent aerating the beer and add the dry hops. Allow the beer condition for 1 week and then bottle or keg. Allow the beer to carbonate and age for 2 weeks and enjoy your W-10 Pitch Black Ale.
