A bourbon barrel exists to impart its rich flavor and color to the bourbon aging inside its white oak staves. For the bourbon aging process, the barrel can only be used once. Barrel Proof Smoking Chips are packaged from authentic Kentucky bourbon barrels. When used as grilling chips, they release a sweet smoky flavor creating a unique richness that can only be achieved by using authentic white oak bourbon barrels. The aroma emanating from the bag of Bourbon Bark feels like someone just handed you a neat pour of your favorite bourbon. Barrel Proof has been granted the distinctive designation of "Kentucky Proud".
