Single Cask Nation Undisclosed Speyside 28 Year Old Single Malt Scotch Whisky

A 28 year old cask bottling from an undisclosed Diageo-owned distillery, though we do know that it’s located southwest of Aberlour. It was distilled in September 1989, and spent just over a quarter of a century maturing in a single refill Oloroso sherry butt. It was bottled by Single Cask Nation in December 2017 at cask strength, 54.3% ABV, and was a limited release of 488 bottles. A very intriguing single malt.
