HEAVEN HILL BOURBON BOTTLE IN BONDThis Kentucky Bourbon is a nod to our distillery's roots, honoring our first release of Bottled in Bond in 1939. It quickly became the best selling brand in Kentucky, retaining its high quality through the years as it continues to be crafted by the founding family according to the strict standards of the Bottled in Bond Act of 1897. With a proof of 100 and an age of 7 years old, this Bourbon embodies our commitment to quality and tradition.
