The "Bottled and Bonded" designation represents a high standard of quality in the American whiskey industry, established by the 1897 Bottled-in-Bond Act to combat deceptive production practices. Whiskeys bearing this label must be produced in one distillation season by a single distiller, aged for at least four years in a government-supervised bonded warehouse, bottled at 100 proof, and clearly labeled with their distillery of origin. This ensures the whiskey's authenticity, quality, and consistency, making the designation a mark of excellence and historical significance for enthusiasts and connoisseurs.
