Jefferson’s Old Rum Cask Finish Bourbon Whiskey
Straight Bourbon Whiskey | 45.1% ABV (90.2 Proof) | 750 mL
Process & Profile
Jefferson’s Old Rum Cask Finish begins as a Kentucky straight bourbon aged for 8 years in traditional new American oak barrels. After its initial aging, the whiskey is shipped to Bermuda where it undergoes a 15-month finishing process in casks previously used for Goslings Family Reserve Rum. This secondary maturation lends layers of molasses, tropical fruit, and spiced sweetness, setting it apart from typical bourbon expressions. Bottled non-chill filtered at 90.2 proof, this release represents Jefferson’s experimental spirit.
