Quick Facts: ABV: 50% (100 Proof)  |  Origin: Kentucky, USA  |  Bottled-in-Bond (minimum 4 years aged)  |  Distillery: Jim Beam, Clermont, KY
Production & Heritage
Old Grand-Dad traces its name to Meredith Basil Hayden Sr., a pioneering Kentucky distiller whose grandson Raymond B. Hayden created the brand in his honor during the 19th century. Today it is produced at the Jim Beam distillery in Clermont, Kentucky, under the Suntory Global Spirits portfolio. The 100 Proof expression carries the Bottled-in-Bond designation, meaning it is the product of a single distillation season, from a single distiller, aged a minimum of four years in a federally bonded warehouse, and bottled at exactly 100 proof — a legal guarantee of authenticity and quality established by the Bottled-in-Bond Act of 1897. The mashbill of 63% corn, 27% rye, and 10% malted barley is notably rye-forward compared to most bourbons, which typically contain 8–15% rye, giving Old Grand-Dad its signature peppery punch.
Tasting Notes
Aroma: Sweet corn and brown sugar rise first, followed by fresh orchard fruit and orange peel. Beneath that, vanilla and warming baking spice develop as the bourbon opens up in the glass.
Taste: The entry is immediately spicy — cinnamon red-hot candy and sharp rye pepper hit the front palate with conviction. At mid-palate, caramel-toffee sweetness balances the spice, layered with roasted peanut, toasted oak, and a subtle cherry-pit bitterness. The high proof carries these flavors with density without becoming harsh.
Finish: Medium-long and distinctly warming, with lingering rye spice, nutmeg, and a dark chocolate-tinged caramel that fades slowly. A dry oak edge appears at the tail end, adding structure and keeping the sweetness honest.
How to Drink Old Grand-Dad 100
At 100 proof, this bourbon holds its own neat but also rewards a few drops of water, which open up the orchard fruit and toffee notes hiding behind the rye spice. It is equally at home on a single large ice cube, where the slow dilution gradually shifts the balance from spice toward caramel. Its bold proof and rye-driven profile also make it an exceptional cocktail bourbon:
Old Fashioned: The high rye spice cuts through sugar and bitters cleanly, producing a structured, less-sweet rendition of the classic.
Boulevardier: The 100 proof stands up to Campari and sweet vermouth without disappearing, adding cinnamon warmth and toasted oak depth.
Whiskey Sour: The peppery backbone balances citrus and simple syrup, preventing the drink from becoming cloying.
