This is a delightful independently bottled single malt that should make a fine collectable for whisky fans. It was distilled all the way back in February 1977 by Allt-á-Bhainne in Speyside before it was matured in a single cask (#21704) for 25 years until it was bottled for the First Cask range at 46% ABV.
This bottle was part of a private collection - if you'd like more detailed photos just get in touch!
