I.W. Harper

I.W. Harper is a Kentucky straight bourbon whiskey originally developed by the Bernheim Distillery and now produced by Diageo in Kentucky, United States. Established in the late 19th century, the brand has historically been positioned as a refined and export-oriented bourbon. As a bourbon, it follows standard American whiskey production methods, including a corn-based mash bill and ageing in new charred oak barrels.

The range includes both entry-level and aged expressions, offering variations in maturity and structure. Compared to other Kentucky bourbons, I.W. Harper is often positioned as lighter and more approachable. Its long-standing brand identity and international presence define its role within the bourbon category.
