Here you have the oldest of all Beam family whiskeys. Established in 1810 by the upright, forward-thinking Abraham Overholt, his namesake whiskey is recognized today as the oldest enduring American Rye in the United States. Made and sold without interruption, this whiskey has seen a thing or two over the centuries. Bottled with a commitment to quality exemplified by an assertive Rye taste, Overholt is a powerful ally to bartenders who prefer it for their cocktails. At one time, it was the most popular spirit in the country. One the Beam family took note of and vowed to continue distilling the way Abraham wanted: proudly true to its industrious spirit.
