Jefferson's Bourbon, a brand of Pernod Ricard USA, debuted its latest innovation: Jefferson's Tropics Aged in Humidity.

Jefferson’s Tropics Aged in Humidity is a fully matured Kentucky straight bourbon finished in Singapore’s extreme heat and humidity to deliver a rich, textured, and completely unique tasting experience, the company says. The newest release is the ultimate culmination of founder Trey Zoeller’s efforts to continue to explore unique maturation techniques and environments, after the success of the innovative Ocean Aged at Sea Voyage Series, it notes. 

“After taking barrels to many different locations, it was evident that the hot and humid climates had such a positive impact on the bourbon. So when homing in on a location to age our first Jefferson’s Tropics Aged in Humidity release, we knew we needed to be near the equator, where the heat and humidity would be year-round and intense,” Zoeller said in a statement. “Singapore — one of my bucket list travel destinations — was absolutely perfect for this experiment. The result is a remarkable bourbon, one that further reinforces my belief that terroir for whiskey comes from the environment that the bourbon matures in rather than the ground from which the grains are grown. The Jefferson’s Tropics Aged in Humidity series embodies the result of this with its richness and complexity — we can’t wait for you to experience it firsthand.”

The journey to create this special liquid began when nine containers, with a combined capacity of 720 barrels of fully matured Kentucky straight bourbon, set sail for Singapore on an ocean ship in July 2019, the company notes. Following that journey, these barrels were exposed to Singapore’s severe heat and humidity for an astounding 18 months resulting in a bourbon that is intensely caramelized and steeped with flavor, it says. The extreme heat essentially slow cooks and caramelizes the sugars in the wood, it adds.

When the containers finally made their way back to Kentucky in March 2023, Zoeller evaluated and selected the flavor profile and proof point, the company notes. The result is a blended bourbon that boasts aromatic baking spices on the nose, notes of bing cherry, toffee, and sea salt, and a long, textured, full-bodied finish, it says. 

Jefferson’s Tropics Aged in Humidity is fully matured and bottled at 52% ABV. An allocated limited edition special release will be available starting September 2023 in fine spirits retailers, restaurants and bars across the United States with a suggested retail price of $99.99 for a 750-ml bottle.
