Our reputation for the extraordinary is characterised by the exceptional oak casks for which The Macallan is renowned. Sourced, crafted, toasted and seasoned under the watchful eye of The Macallan Master of Wood, the hand-picked casks are delivered to the demanding specifications of The Macallan Whisky Mastery Team. For every expression of The Macallan, the quality of the whisky is largely dependent on the quality of the oak casks it is matured in, as well as the quality of our 'new make' spirit distilled from water, yeast and barley. With up to 80% of The Macallan’s final character and flavour determined by cask quality, the oak cask is the most prominent factor in ensuring and delivering the quality and style of our single malt.

All of our whiskies take 100% of their colour from the wood in which they are matured. As wood is a natural product, each tree is different and in turn, imparts different flavours and colours to the whisky during maturation. The skill of the whisky makers ensures colour is as consistent as possible from bottling to bottling, through the management and selection of the casks which provide the spectrum of natural colour essential to The Macallan single malt.

The Macallan works closely with fully integrated ‘tree to finished seasoned cask’ companies in Spain; to identify the oak trees in the forests of northern Spain, fell the trees, saw and air dry the oak staves before shipping them to the south for further air-drying to reduce the moisture even more. The casks are then seasoned for 18 months before making the journey to Scotland where they are filled with The Macallan ‘new make’ spirit.
