Courtesy of Ozark Beer cofounders Andy Coates and Lacie Bray, here is a homebrew-scale recipe for their BDCS—a bourbon barrel–aged double cream stout meant for months of wood-aging to balance and soften its profile.
Mill grains and mash at 154°F (68°C) for 60 minutes.
Vorlauf until the runnings are clear of particles, then switch on the burner and run off into the kettle. Sparge at 170°F (77°C), topping up as necessary to get about 7 gallons (26.5 liters) of wort—or more, depending on your evaporation rate.
(If dividing the grist to conduct two mashes, begin boiling the first batch while mashing the second.) Boil for about 2 hours—or longer if necessary to get near the target starting gravity—adding hops and lactose according to the schedule.
After the boil, chill to 66°F (19°C), aerate well, and add plenty of healthy yeast. Ferment at 68°F (20°C) until fermentation is complete and gravity has stabilized.
Rack the beer into a bourbon barrel—or a sanitized fermentor with about 3 oz (85 g) of bourbon-soaked oak cubes—and age patiently.
