Jack Daniel's Black Label Old No.7 is a renowned Tennessee whiskey produced by the Jack Daniel's Distillery, located in Lynchburg, Tennessee. This whiskey is crafted using a sour mash process, which involves using a portion of the mash from a previous distillation to start the fermentation of the new batch. The whiskey is then charcoal mellowed through the Lincoln County Process, which gives it a smooth character. It is aged in handcrafted barrels made by the distillery's own coopers, contributing to its rich amber color and distinctive flavor profile. The whiskey features notes of vanilla, toasted oak, and caramel, with a slightly smoky finish. It has an ABV of 40% and is a staple in the world of American whiskeys.
