Our exceptional oak casks are the single greatest contributor to the outstanding quality, natural colours and distinctive aromas and flavours of The Macallan. These oak casks are crafted to their own specifications and account for up to 80% of the final aromas and flavours of The Macallan. In 2009, world renowned photographer was asked to create a series of six customer covers for the Macallan Whisky Maker's edition. This is known as the "X-Ray" series since he used an x-ray machine en lieu of a traditional camera. Macallan Whisky Maker’s Edition has been personally crafted by the distillery’s manager, Bob Dalgarno, from a mix of sherry and bourbon casks and bottled at his preferred drinking strength of 42.8%.
