Most people picture one thing when they think of Jack Daniel’s, and that is the squat square bottle of Old No. Each of the five below tells us something about how a heritage distillery actually operates, and about how accident and intention combine to create the rarest Jack Daniel’s bottles now in circulation. Jack Daniel’s first sought an unaged rye whiskey designation, and the Alcohol and Tobacco Tax and Trade Bureau firmly refused it. A label inspection at the gate revealed what she had, and the tale has since become part of the folklore around these rare Jack Daniel’s bottles. For collectors these remain the bottles worth chasing, long after the standard square bottle has been poured and forgotten.
