The Blair Athol Distillery is located near Pitlochry in the Highlands of Scotland. Blair Athol was originally the estate village of the picturesque Blair Castle, at whose gates the distillery now stands. The distillery was licensed in 1825, on the site of an older distillery, and was purchased by Arthur Bell and Sons in 1933. Since then the distillery was purchased by the Guinness Group in 1985. Running 4 stills, the distillery produces approximately 2,300,000 litres annually.

This single malt whisky was distilled in 2008 at the Blair Atholt Distillery before being placed in refill Hogsheads. It was then finished in a Fresh Sherry Butt for 25 months and bottled in 2021 at 54.3% ABV as part of the Signatory Vintage Cask Strength Collection.
