sengoku turtle single cask malt whisky cask 1050In 2022, two new whiskies from the Sengoku Turtle were introduced. This one matured for just over five years in an American white oak cask before being bottled at 49. 5% ABV. The malt whisky was purchased from Scotland, as the distillery does not yet own any casks of whisky of that age. A total of no more than 500 bottles were released worldwide.
