Bourbon Barrel Aged Barleywine is a version of our Old Dipsea Barleywine that has been aged in Bourbon Barrels for about a year. This ageing contributes wood and bourbon flavors to the beer. The micro-oxygenation that occurs in the barrels mellows and smoothes out the high alcohol as dried and over-rip fruit characters evolve. Sometimes we add wild yeast for another layer of complexity. 11.0% Alcohol by Volume
