The Act certified the quality of any whiskey carrying an official designation on the bottle. To earn this distinction, a whisky had to be distilled at a single distillery during a single distilling season, aged at least four years and be bottled at 100 proof. It was a distinction that Jack's whiskey easily earned. After all, Jack had been doing it years before it was required. 120 years later, the Bottled in Bond Act is proof of America's commitment to ensuring the quality of whiskey. And Jack Daniel's Bottled-in-Bond whiskey is a tribute to the man who believed in quality from the very beginning. Exclusive to travel retail.
