Boysenberry is a barrel-aged sour ale that combines our take on a traditional, Lambic-style base beer, with a fruit not typically found in traditional Lambics. We ferment our base beer, Basis, for six to eight months in oak tanks to produce tart flavors, fruity notes and a funky character. Then, we blend individual batches before aging on boysenberry fruit for an additional month to extract the perfect balance of fruit flavor. We bottle conditioned this beer, resulting in a fine carbonation and spritzy mouthfeel.
