The 2014 Double DBA imperial special bitter is Firestone Walker’s flagship DBA brewed at double strength, using twice the amount of malts and hops. As with the regular DBA, the 2014 Double DBA was partially fermented in a union of new American oak barrels. After fermentation, the beer was racked and returned to the union barrels as well as bourbon barrels, where it aged for one year. The barrel mix for the 2014 Double DBA included vessels from Woodford Reserve, Elijah Craig and Four Roses.
