Jack Daniel’s Single Barrel Heritage Barrel is a rare release honoring the craft of barrel-making. Each barrel was hand selected by Master Distiller Jeff Arnett and slowly heated to create a deeper, richer toasted layer before charring. This careful process enhances the whiskey’s depth, complexity, and signature Tennessee character. Bottled at 100 proof and released in Fall 2018, this 750ml Single Barrel expression comes from only 200 heritage barrels. The result is a bold, full-bodied whiskey that reflects tradition, patience, and pride—crafted to honor Jack Daniel’s earliest coopers and the legacy of Mr. Jack himself.
