Jameson 18 Year Old Triple Distilled Irish Whiskey is a special blend of three whiskies that have each aged at least 18 years in hand-selected American bourbon and European oak casks in Jameson's Midleton warehouse. As a result of its 18 year beauty rest, the whiskey's nose opens with spicy oak and toffee, which is followed by more toffee and fudge notes on the palate, as well as subtle hints of sherry. Just before being bottled, the whiskey is finished in first-fill bourbon casks, which leads to a smooth, vanilla finish, brightened by previous notes of toffee and caramel.
