In the late 1800s, the government passed the Bottled in Bond Act. The Act certified the quality of any whiskey carrying an official designation on the bottle. To earn this distinction, a whiskey had to be distilled at a single distillery during a single distilling season, aged at least four years and be bottled at 100 proof. With rich and bold flavors, Jack Daniel’s Bottled-in-Bond whiskey is a tribute to the man who believed in quality from the very beginning.
