Jefferson's Tropics Bourbon Whiskey

Jefferson's Tropics Aged in Humidity is a Kentucky straight bourbon taken somewhere no bourbon had gone: after maturing fully in Kentucky, barrels traveled by ocean ship to Singapore, where they spent 18 months in non-climate-controlled warehouses averaging 82°F and ~84% humidity — then returned for blending and bottling at 104 proof (52% ABV) in 750mL. Founder Trey Zoeller's follow-up to the famous Ocean series, it caramelizes wood sugars at equatorial pace. Order it online at Del Mesa Liquor, San Diego, CA.

Slow-Cooked by the Equator

Jefferson's made its name with the Ocean series — bourbon aged aboard ships at sea. Tropics applies the same climate-as-ingredient philosophy on land: 720 barrels in nine containers sailed to Singapore in 2019, sat through two rainy seasons of unrelenting heat and humidity, and came home measurably darker and woodier. In-house master blender science showed the Singapore whiskey at bottling strength was 10% darker than the Kentucky baseline — evaporation concentrating wood and flavor compounds faster than a temperate rickhouse ever could. The official profile runs Bing cherry, toffee, and a hint of sea salt. Browse more Jefferson's experiments or explore bourbon.

Tasting Notes

Aromatic baking spices — cinnamon and clove — on the nose; notes of Bing cherry, toffee, and a hint of sea salt on the palate with molasses, stewed pear, tobacco leaf, and crème brûlée vanilla; long, textured, full-bodied finish.

How to Enjoy

Neat or with a large cube to soften the spice — the contemplative-sipper profile begs for dark chocolate or aged cheese alongside.
