Jefferson's Reserve Old Rum Cask finish has spent many years maturing in American white oak casks before being transferred into a specially selected old rum casks that previously held Goslings Family Reserve, awarded the best aged rum in Bermuda and the World. Extra aging for 15 months in these casks created a rich and rounded bourbon whiskey; marrying the unmistakable flavor of an award winning bourbon with the mouth feel, complexity and finish of a reserve rum. The results of this marriage will be award winning in its own right.
