Heaven's Door Double Barrel was developed in collaboration with musician Bob Dylan. The whiskeys are named after his big hit "Knocking on Heaven's Door" from 1973. The bottle design shows the welded iron gate that Bob Dylan made in his Black Buffalo Ironworks studio. Double Barrel is a blend of three different American whiskeys that have also been aged for one year in toasted fresh white oak barrels. The high alcohol content keeps the balance with the intense caramel, oak, citrus and spice notes of the barrels.
