The recipe for the various types of products produced by Jack Daniel's Tennessee whiskey varies, but the standard black label whiskey is made of mash consisting of corn, rye and malted barley. The mash is distilled in copper stills before being filtered through 10 foot stacks of sugar maple charcoal.
After the product is put through the filters, which is called mellowing, the whiskey is stored in newly crafted oak barrels. These barrels give the finish product its color and much of its flavor. An interesting fact about the uses of the barrels after the whiskey is aged is that many of them go to Scotland to produce Scotch whiskey. Another portion of them go to Louisiana to be used in the production of Tabasco sauce.
