Jack Daniel's Old No. 7 Tennessee Whiskey is the world's best-selling American whiskey, crafted at America's oldest registered distillery in Lynchburg, Tennessee, established in 1866 . Made from a blend of corn, rye, and barley malt mixed with iron-free Cave Spring water, this iconic spirit is charcoal mellowed drop by drop through 10 feet of sugar maple charcoal—a process known as the Lincoln County Process—before being matured in handcrafted white oak barrels . The result is a smooth, balanced whiskey with notes of vanilla, caramel, and oak, perfect for enjoying neat, on the rocks, or in classic cocktails like the Old Fashioned or Whiskey Sour .
