Following distillation, The Macallan distillers remove the heads and tails of the whisky and collect approximately 16% of the spirit to fill into casks for maturation. This "cut,"which is among the highest of any Scottish distillery, results in a more full-bodied and and rich whisky.

Macallan Rare Cask Single Malt Scotch Whisky showcases two of Macallan's most fundamental pillars: natural color and sherry oak casks, according to Macallan Whisky Maker Robert Dalgarno. Dalgarno hand selected fewer than one percent of the casks maturing on the Macallan estate in order to craft this rare whisky.
