Bottled-in-Bond Bourbon

American straight bourbon meeting the Bottled-in-Bond Act of 1897: product of one distillery, one distillation season, aged at least 4 years in a federally bonded warehouse, and bottled at exactly 100 proof (50% ABV). Higher-proof, single-season character — richer caramel, vanilla, toasted oak, and baking spice than standard 80-proof bourbon. Reference examples: Heaven Hill 7 Year Bottled in Bond, Old Grand-Dad Bonded, Evan Williams Bottled in Bond, J.T.S. Brown Bonded.
