Barrell Foundation Double Barrel Bourbon exhibits all the complexity that you find in a Barrell Craft Spirits bourbon at a lower proof. Secondary maturation in new American oak casks enhances the notes of dark chocolate, leather, dried fruit, and toasted marshmallows, while the twenty-three percent rye in the mash bill gives a richness to the blend. This is a versatile, full-flavored bourbon perfect for enjoying neat, over ice or in a cocktail.
