It's a bottle of Aberfeldy 15 Year Old single malt Scotch whisky, which was bottled as part of the immensely popular Flora and Fauna series. This one even comes with its original presentation box. The label (and aforementioned accompanying box) has some sort of squirrel on it, which is wonderful. Squirrels are pretty great, as far as members of the Sciuridae family which you might choose to put on a whisky bottle go.

This bottle was part of a private collection - if you'd like more detailed photos just get in touch!
