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 Distillery which was founded in 1875. They let their whiskey slowly drip through 10ft of hard sugar maple charcoal so it comes out with its distinctive smoothness. It’s a costly, time-consuming process and if it sounds extravagant, well, it is.
