This bottling of Croftengea was distilled in June 2007 at the Loch Lomond distillery, and then spent a decade maturing in a second-fill bourbon hogshead. In 2017, it was bottled at a cask strength of 57.6% ABV by the Jewish Whisky Company for the Single Cask Nation series. 297 bottles were produced. 

Single Cask Nation is a heavily peated, characterized by a complex mix of coastal smoke, tropical fruit, and savory, "funky" notes. Matured in second-fill bourbon, it delivers a unique profile of honey, charred pineapple, and citrus, often balanced with earthy, rustic undertones and a long, peppery smoke finish.
