1. Limestone Spring Water: The base of Jack Daniel's Whiskey is spring water from the limestone cave in Lynchburg, TN. This water is mixed with and cooked with a grain mixture of 80% corn, 8% rye, and 12% barley to create their signature mash. 

2. Charcoal: They make their own charcoal by burning slats of sugar maple until they are embers. Those embers are then raked over and ready to mellow the whiskey mixture. 

3. Distillation: The mash mixture is then distilled over the charcoal for 3-5 days; the mash then ferments for 6 days.

4. Charcoal Mellowing: The whiskey mixture then drips through 10 feet of sugar maple charcoal; this is what gives Jack Daniel's its signature smoothness. 

5. Barrel: They hand craft white oak barrels where the distilled mixture will mature. 

6. Maturation: The distilled liquid goes into the barrels clear and comes out its signature amber color. The timeline of maturation changes depending on season and temperature. 

THE BARREL

The image above is one of the white oak barrels mentioned in step 5. These barrels are not assembled by nails or glue, they stay together by precise craftmanship. Each barrel is compiled of 33 woods slats. These barrels are critical to the integrity of the brand as they hone in on the classic flavors that make Jack Daniel's what it is. Aging whiskey is a long process and Jack Daniel's technique has not changed in 150 years; further representing the ideals of the south, tradition, hard work, and good liquor. The Jack Daniel's distillery in Lynchburg, TN also happens to be the oldest registered distillery in the United States (Mint Julep Nashville).
