Jack Daniel's Old No. 7 is a Tennessee whiskey known for its smooth flavor and distinctive character. It is produced by the Jack Daniel Distillery, which was founded in 1866 by Jack Daniel himself. The whiskey is made from a mash bill of corn, rye, and malted barley, and it undergoes a charcoal mellowing process known as the Lincoln County Process, which contributes to its unique taste. The name "Old No. 7" refers to the distillery's original recipe, which has remained a closely guarded secret. This whiskey is often enjoyed neat, on the rocks, or in cocktails, making it a popular choice among whiskey enthusiasts worldwide.
