Our Master Distiller, Billy Walker, is passionate about wood management, closely monitoring the development of the whisky until he finds the perfect balance of distillery and cask influence. From amongst the 50,000 casks maturing across our 16 warehouses, Billy hand-selected five Pedro Ximenez and Oloroso Sherry Puncheons for this bottling. With a very limited release of only 1,600 bottles available worldwide, The GlenAllachie 21 years old is offered at cask strength, natural colour and non-chill filtered, meaning this annual small batch release showcases GlenAllachie in its purest form.

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.
