Jefferson's Ocean Aged at Sea Very Small Batch Straight Bourbon Whiskey 750ml

Most bourbon ages quietly in a rickhouse. Jefferson’s Ocean sails. Founded in 1997 by Trey Zoeller, Jefferson’s has built its name on experimentation, and Ocean is its most adventurous experiment: barrels of bourbon loaded onto a ship and aged at sea, rocking with the waves, passing through tropical heat and cool ocean air, crossing the equator, and docking at ports on multiple continents. The constant motion pushes the whiskey in and out of the charred oak, and extreme temperature swings accelerate the aging.

The idea began as an experiment with three bourbon barrels, when Zoeller decided to see what would happen if bourbon were left to age on a ship in extreme conditions. In the distillery’s words, “the result was a thick, dark bourbon that showcases complex flavors reminiscent of other spirits; the almost black color and caramel flavors resemble a dark rum as the sugars within the barrels caramelized; the briny, savory taste from the barrels breathing the sea air is reminiscent of Islay Scotch; and at its core, it’s a true bourbon.”

Each release is a numbered “voyage,” with its own route, its own barrels, and its own character. We are currently shipping Voyage 34, but the voyage number may change depending on availability, and tasting notes can vary slightly from voyage to voyage. The whiskey is a very small batch blend of Kentucky straight bourbons, sourced from undisclosed distilleries (so the mash bills are unknown), bottled at 45% ABV (90 proof).

The producer’s notes for Voyage 34: “Nose: Crème brûlée, sweet tobacco and sea spray. Flavor: Caramel, light brown sugar, cinnamon, sea salt and a hint of espresso. Finish: Long, smooth finish that thoroughly coats the palate with notes of classic Cracker Jacks and sea salt.” Another description adds “a thick, viscous texture” and “a unique savory brine from the salt air,” and the Voyage 34 sailed, per one retailer, across the equator and docked at more than 25 ports. A tasting panel at the John Barleycorn Awards found “a touch of ginger, rancio, and cocoa on the nose with even more cocoa plus fun fruity notes on the palate, capped by a pleasingly soft peanut finish. Really well balanced.”

To be balanced, reviewers of earlier voyages were mixed. The Whiskey Wash found “a soft salt and light smoke note mixed with the caramel that I cannot recall encountering in any other bourbon,” though “those notes are very subdued,” while ThirtyOne Whiskey found an earlier release “a bit disappointing when compared to the flavor of other straight bourbon in this category and price range.” A K&L reviewer, on the other hand, called a later release “by far the best Ocean release I’ve yet tasted,” with “depth on the next level.” That’s a fair guide: the sea-aging adds a subtle brininess and a rounder, sweeter, more caramelized character, and it’s more of a conversation piece than a dramatic flavor departure.

It’s a great gift for bourbon fans, travelers, and anyone who likes a story, and it’s easy to sip neat or on the rocks. A short pour in an Old Fashioned also works well, where the sea salt and caramel come through.
