YEAST
White Labs WLP001 California Ale, Wyeast 1056 American Ale, Fermentis SafAle US-05, or other clean-fermenting ale strain

DIRECTIONS
Mill the grains, add the rice hulls (if using them to help avoid a stuck mash), and mash at 155°F (68°C) for 60 minutes, targeting a liquor-to-grist ratio of 1 qt/lb (2.1 l/kg). Adjust the mash pH to 5.4 if necessary. Vorlauf until the runnings are clear of particles, then start the burner and run off into the kettle. Sparge and top up as necessary to get about 8 gallons (30 liters) of wort if possible, targeting a pre-boil gravity of about 1.092. Boil for about 4 hours or until the gravity approaches the target starting gravity (1.120), adding hops when about 1 hour is left in the boil. Chill to 64°F (18°C), add the yeast nutrient, aerate well, and pitch plenty of healthy yeast. Ferment at 68–70°F (20–21°C).

When fermentation is complete and gravity has stabilized, wait a few more days, then drop the temperature to 50°F (10°C). Drop the yeast if possible, or rack into secondary purged with CO2. Allow the temperature to free rise back to ambient temperature. Rack into a 5-gallon (19-liter) bourbon barrel purged with CO2, leaving as little head space as possible—or, if lacking the barrel, add about 3 oz (85 g) of bourbon-soaked oak cubes to secondary. Age patiently but sample often—using a small barrel reduces the aging time—minimizing oxygen pickup as much as possible.

BREWER’S NOTES
Feel free to sub in your favorite base malt or blend of base malts for the two-row. Likewise, any good bittering hop at 20 IBUs can go in for Columbus.
