All aboard for the fourth expression from the Bushmills Steamship Collection, Rum Cask Reserve! The series was released originally for the Travel Retail market, inspired by the 125th anniversary of the SS Bushmills maiden voyage. The Irish single malt has been matured in first-fill Caribbean rum casks, with the expression inspired by SS Bushmills’ homeward bound journey that included a stop in St. Vincent in the Caribbean, where the ship was stocked with rum to bring back to The Old Bushmills Distillery.
