Jefferson’s Reserve Old Rum Cask Finish Bourbon was first aged in new American oak barrels for approximately eight years before being extra-matured in ex-rum barrels from Gosling’s Family Reserve for an additional fifteen months. Gosling’s is a high-caliber rum producer out of Bermuda that is particularly well-known for using ex-bourbon barrels to age their rum! These special barrels give Jefferson’s Reserve Old Rum Cask Finish Bourbon its unique and robust characteristics. As a result of this unique aging process, the bourbon has an aroma of bananas, vanilla, and almond, leading to a palate of salt, spiced rum, maple, and dried fruits. The long finish leaves the taste of cereal grains lingering on the tongue.
