BUSTER'S BARREL The whiskey that started it all. Capturing an unforgettable era was our mission; to create a rugged and rebellious whiskey, yet refined with the utmost craftsmanship. Bottled intentionally at a high proof so customers can choose to either drink it full- strength, or enjoy the experience of the whiskey opening up with the addition of a little water or ice. Not a whiskey for the light-hearted. Our flagship, 291 Colorado Whiskey Barrel Proof- Unique, yet traditional, single barrel rye whiskey distilled in a copper pot still, aged in American white oak deep char barrels and finished with toasted Aspen staves to give a unique flavor.
