Undisclosed Speyside Distillery 29 Year Old 1992 (cask 4825) - Infrequent Flyers (Alistair Walker) 70cl Whisky

Forget UFOs, Alistair Walker's Infrequent Flyers series has whisky from a USD – Undisclosed Speyside Distillery. This expression was distilled in 1992 (in Speyside, no less!) and matured for 29 years, including a finishing period in a rye barrel. After that, it was bottled up at 46.9% ABV, with an outturn of just 274 bottles. Delicious, and mysterious.
