From the maker:

Basil Hayden’s® 10 Year Old Bourbon features the same high-rye bourbon recipe that Basil Hayden’s fans know and love, but the whiskey is aged in barrels longer to create another layer of complexity and deeper flavor.

The result of the extra aging is a distinct whiskey with big oak aromas along with hints of char and vanilla. Basil Hayden’s® trademark spice shines through as the perfect complement to the caramel sweetness and wood flavors, making the whiskey a memorable one for fans and newcomers alike.
