Old Grand-Dad Bottled-in-Bond is a classic Kentucky Straight Bourbon Whiskey bottled at 100 proof (50% ABV), produced by James B. Beam Distilling Co. and rooted in a tradition dating back to 1882. The "BIB" designation refers to the Bottled-in-Bond Act of 1897, one of the earliest consumer protection laws in the United States, which guarantees that the whiskey is the product of a single distillation season and a single distiller, aged a minimum of four years in a federally bonded warehouse, and bottled at exactly 100 proof.

Old Grand-Dad is known for its high-rye mash bill, which gives the bourbon a distinctively spicy, bold character. Tasting notes include caramel, oak, and warm baking spice, complemented by hints of vanilla and citrus, with a rich, warming finish. During Prohibition, the Bonded expression was one of the most popular spirits in the country, available by prescription for medicinal use, a testament to its longstanding reputation for quality.

At 100 proof, Old Grand-Dad Bonded is equally suited for sipping neat, on the rocks, or as the backbone of classic cocktails such as the Old Fashioned or Manhattan. It is a perennial favorite among bourbon enthusiasts who value heritage, authenticity, and bold high-rye flavor.
