Jack Daniel's Whiskey barrel charcoal briquets. Made by combining authentic Jack Daniel's oak aging whiskey barrel wood with premium all natural hardwood charcoal. During the aging process， the whiskey is drawn in and out of the wood， giving it its distinctive color and flavor. A portion remains in the wood after the barrels are empties and some of them are made into Jack Daniel's whiskey barrel smoking chips. These chips add the distinct whiskey flavor to foods cooked on your grill or electric smoker. Creates a smoky and subtly sweet whiskey flavor.
