Built in 1967 as a small compact distillery, GlenAllachie was the fourth distillery designed by William Delme-Evans. The complete whisky making process was gravity fed and combined with unusual horizontal condensers it was a triumph of engineering and design. Fast forward 50 years and we're reaping the benefit when we bring you the GlenAllachie 25 year old. A combination of Pedro Ximinez and Oloroso casks specially selected by our Master Distiller Billy Walker and bottled at a slightly higher ABV of 48%.

Crafted to showcase complexity and depth, Rare Cask is drawn from the broadest spectrum of casks used in maturation on The Macallan Estate. Hand-picked by our whisky making team, the combination of sherry seasoned American and European oak casks - a high proportion of them first fill - deliver an exquisite and unmistakably woody whisky with a rich hue. Incomparable access to the most extensive range of cooperages in Spain gives us some of the finest and scarcest casks to choose from to create Rare Cask, which results in a diversity in the finished whisky unlike other Macallan expression. It is the role of the whisky making team to get to know each and every cask in detail, from how it interacts with the spirit to the spectrum of colours it imparts. This relationship between cask and craftsman, spirit and skill, ultimately give us Rare Cask.
