The Irishman Caribbean Cask Finish is an Irish whiskey known for its unique rum cask finish, which adds a tropical twist to the traditional Irish whiskey profile. It is a blend of Single Malt and Single Pot Still whiskeys, initially matured in American oak bourbon barrels, then finished in rum casks from St. Lucia. This process imparts notes of tropical fruits, caramel, and oak, with a smooth, sweet finish.
