Jefferson Ocean Aged at Sea Voyage 20 was inspired by the original Jefferson's Ocean, which was new-filled bourbon barrels. The Jefferson's Ocean: Aged at Sea takes older bourbon barrels and brings it around the world. Stopping in 5 different continents and crossing the equator 4 times, this bourbon truly is a world beater. The aroma of this bourbon whiskey is filled with notes of chewy caramel and vanilla over a light sea-salt and matchstick background. The palate is rich and smooth with notes of chewy toffee and a smoking oak in brine. The finish is long and sweet with a blooming citrus zest.
