Continuing the legacy of the pinnacle series in Irish single malt, Bushmills is proud to introduce the 4th release of its Rare Casks, the highest aged expression within the collection to date, a beautifully crafted marriage of bourbon casks, sherry casks and virgin American oak. Triple cask-matured, this 31YO whiskey is first aged for 14 years in Bourbon and Sherry casks before settling into pristine new American Oak casks that were constructed and toasted to the Bushmills proprietary specification. An unparalleled whiskey, Rare Cask Limited Release #4 is limited to only 780 bottles and is exclusive to the United States.
