Barrelworks, a division of Firestone Walker Brewery Co., has released its next beer, a 6.6 percent ABV American wild red ale named Agrestic. The official debut was at a Barrelworks events inside the Paso Robles, Calif.-based brewery on Sept. 20.

Agrestic began its life as Double Barrel Ale, but became something altogether different after a proprietary collection of microflora was added and it was aged in oak barrels. According to a press release, the recipe consists of a selection of different agrestic lots matured from eight to 24 months in French (87 percent) and American oak (13 percent) barrels.
