Jack Daniel's is a brand of Tennessee whiskey and the best-selling whiskey in the world. It is produced in Lynchburg, Tennessee, by the Jack Daniel's Distillery, which has been owned by the Brown-Forman Corporation since 1956.
The product meets the regulatory criteria for classification as straight bourbon, although the company chooses not to use this classification. It markets the beverage as "Tennessee whiskey" rather than "Tennessee bourbon." The mash for Jack Daniel's is made from corn, rye, and malted barley and is distilled in copper stills. It is then filtered through 3.0-meter-high stacks of sugar maple charcoal.
The company refers to this filtering step as "mellowing." This additional step, known as the Lincoln County Process, removes impurities and the taste of corn. The product label mentions that it is a "sour mash" whiskey, meaning that a portion of the wet solids from a previously used batch is mixed into the mash to ensure a more consistent fermentation process.
After being used to mature Jack Daniel's whiskey, many barrels go to Scotland, where they are used to make Scotch whisky. Some barrels are leased by the Glenmorangie Distillery.
