IBU = 33  SRM = 4  ABV = 9.4%

This is the fourth recipe members of the MASH homebrew club brewed and filled the second barrel (the clean barrel) with after fermentation for extended aging.

Ingredients
13.5 lbs. (6.1 kg) German Pilsner malt
1.5 lbs. (0.68 kg) table sugar (sucrose)
8.2 AAU Loral Cryo® hops (60 min.) (0.39 oz./11 g at 21.5% alpha acids)
2.3 AAU Hallertau hops (10 min.) (0.5 oz./14 g at 4.5% alpha acids)
2.3 AAU Styrian Goldings hops (10 min.) (0.5 oz./14 g at 4.5% alpha acids)
½ Whirlfloc tablet (10 min.)
½ tsp. yeast nutrients (10 min.)
White Labs WLP570 (Belgian Golden Ale), Wyeast 1388 (Belgian Strong Ale), or Mangrove Jack’s M31 (Belgian Triple) yeast

Step by Step
This is a single infusion mash with the addition of 3 g calcium chloride, 2.4 g gypsum, 1.8 g of Epsom salt, and a pinch of table salt. Phosphoric acid is added to the mash water to achieve a mash pH of 5.2 and sparge water to a pH of 6. Stabilize mash temperature at 148 °F (64 °C) and hold for 75 minutes. Lauter as usual collecting 7 gallons (26.5 L). Boil for 90 minutes adding the first hops 30 minutes after the start of the boil and the second hop addition, sucrose, Whirlfloc, and yeast nutrients with 10 minutes remaining in the boil. 

After the boil is finished, chill the wort down to yeast pitch temperature, aerate well if using liquid yeast, then pitch the yeast. Ferment at 68 °F (20 °C) for 7 days before transferring into the barrel. 

Extract option: Swap out the Pilsner malt for 7.3 lbs. (3.3 kg) Pilsen dried malt extract (DME). Start with 3 gallons of water and bring up to almost a boil. Turn off heat and add half of the DME. Bring to a boil and add the first hop addition. Boil for 60 minutes. Add the second half of DME along with the second hop addition, sucrose, Whirlfloc, and yeast nutrients with 10 minutes left in the boil. 

Chill wort down to fermentation temperature then add water to make 5 gallons (19 L). Follow remaining instruction from the all-grain recipe.
