Hard to find any info on this one. All I can find is that it was the last cask from that distillery before it closed, but no information on how many casks of it there were, or how many bottles were produced. Saw a couple reviews of other vintages from this distiller, which were being scored around the mid to upper 80's. Kept sealed, and stored in a cool dark location, it should keep as long as you want to hold onto it. I saw another bottle of this vintage being offered for something like 650 Pounds. Wish I could have found something more.
Drink it if you want, hold onto it for a special occasion, or sell it for some spare cash.
