"Procuring this Speyside malt (usually labelled as Highland malt by the distillery) was our toughest job yet" - Artful Dodger Whisky Company 
It may be hard to imagine today, but for much of the 20th century, Macallan was primarily a constituent malt in blends. It was not until the 1980s downturn in the market that the distillery decided to focus on its single malt brand. Fortuitously, this coincided with the crest of a wave of enthusiasm for the high quality releases that the distillery had licensed to Campbell, Hope & King and Gordon & MacPhail in the 1960s and 1970s. These remain some of the most collectible on the market. While global single malt sales volume is still lead by Speyside neighbours, Glenfiddich and Glenlivet, Macallan is easily the most sought after. So much so in fact, that they had to open a brand new distillery in 2018, a subterranean architectural masterpiece within the Easter Elchies estate, boasting 36 copper pot stills.
This whisky was distilled on 10th November 2005 and aged in a ex-Bourbon hogshead for 15 years. It was bottled at cask strength on 21st April 2021 by Artful Dodger. 
Although the bottle or carton does not carry the name Macallan, the company confirmed that this is indeed from the famous Speysider via their Instagram feed.
