During its 150 year history, Jack Daniel's has won numerous gold medals around the world. Its success can be put down to the unique way in which the famous 'Old No.7' brand is made, the same way it always has - using the finest corn, rye and barley malt; pure, iron-free water from the Cave Spring in the Distillery hollow; being mellowed through 10 feet of sugar maple charcoal; and aged in hand-crafted charred oak barrels.
