Ardbeg, established in 1815 on the Isle of Islay, is renowned for its bold, complex, and heavily peated whiskies. *An Oa* is aged in a combination of ex-PX Sherry and Bourbon casks, imparting rich notes of dried fruit and vanilla. It then undergoes a final maturation in French oak, resulting in a smoother, more rounded whisky with flavors of toffee, spice, caramel, and ripe banana.
