Jack Daniel's Bonded is a Bottled-in-Bond Tennessee whiskey, bottled at 100 proof under the strict US bonded rules: the product of a single distilling season at one distillery and aged at least four years in a bonded warehouse. Charcoal mellowed and matured in new charred American oak, it is richer than Old No. 7, with caramel, toasted oak, dark fruit and baking spice. Ideal neat, on ice or in a robust Old Fashioned.
