Jack Daniels Blackberry is based on the brand's classic Jack Daniel's whiskey, which is complemented by a blueberry liqueur also made at the Jack Daniels distillery. The result is a distinctive and deliciously fruity liqueur characterized by a smooth taste with notes of blueberries, vanilla, toasted oak, and honey, among others. Jack Daniels Blackberry can easily be mixed with soft drinks such as Coca-Cola or Sprite.
