The M Decanter 2020 Release is a blend of several casks of whisky that were selected by Macallan`s Master Whisky Maker, Sarah Burgess. The singe malt was aged in sherry-seasoned oak casks, which are a signature of The Macallan`s maturation process. The decanter itself is a work of art, designed by the renowned French crystal maker Lalique. It is made from crystal and features a geometric pattern that is meant to reflect the complexity and richness of the whisky inside.
