Old Grand-Dad

Old Grand-Dad is a Kentucky straight bourbon whiskey produced by Beam Suntory in Kentucky, United States. The brand traces its origins to the 19th century and is named after Basil Hayden Sr., a figure associated with high-rye bourbon mash bills. As a bourbon, it follows standard production methods, including ageing in new charred oak barrels.

The range includes expressions at varying proof levels, often emphasising a higher rye content compared to many other bourbons. Compared to softer, corn-forward bourbons, Old Grand-Dad is typically positioned as more spice-driven. Its mash bill composition and historical branding define its role within the Kentucky bourbon category.
