Old Grand Dad Bourbon

Old Grand-Dad is a Kentucky straight bourbon built on a high-rye mash bill, a recipe attributed to distiller Basil Hayden Sr. and carried forward by the Wathen family distilling operation before eventually passing to Jim Beam. That elevated rye content drives the brand's characteristic spice-forward profile, setting it apart from wheated or corn-dominant bourbons. The standard 80 proof and Bottled in Bond expressions offer straightforward rye-driven character, while the 114 proof amplifies heat and intensity. Vintage bottlings - including a 1954 Bottled in Bond decanter, a 1969 100 proof, and a rare 1917 Prohibition-era pint from Wathen Distillers - document decades of the brand's evolution and serve as primary source material for collectors tracing American bourbon history.
