XO Caribbean Rum Cask

Tullamore Dew XO is a triple blend of pot still, malt, and grain whisky finished in first-fill XO Caribbean rum casks. The expression honours the historical role of Irish immigrants in Caribbean rum production—a connection that first appeared on bottle in 2017.

Maturation in Demerara rum barrels imparts tropical character: banana, dates, raisin, and caramel form the foundation, layered with vanilla and oak. The rum influence remains restrained, allowing the Irish whiskey base to remain the protagonist.

On the palate, apple and floral notes emerge first, then toffee, honey, cinnamon, and coconut. The finish is lengthy and refined—toasted sugar, cashew, and a whisper of bitter cocoa linger. This is a measured expression, not a rum-dominated one, but a genuine fusion of Irish craft and Caribbean influence.
