Rare Cask. The Macallan — crafted exclusively from first-fill sherry seasoned oak casks that represent less than 1% of the casks maturing at The Macallan distillery at any given time — the most selective tier of The Macallan’s ongoing standard range.The ‘less than 1%’ threshold reflects the actual scarcity of first-fill sherry seasoned casks meeting The Macallan’s quality standard within their warehouse inventory. The vast majority of The Macallan’s production uses refill casks that have previously held spirit; first-fill sherry casks, used only once before whisky enters them, impart the deepest, most concentrated sherry character available from any cask in the warehouse.The Rare Cask is non-age-statement by necessity: selecting only from the most exceptional first-fill sherry casks available at each bottling means the age profile varies batch to batch depending on what meets the threshold at that time.Specs Distillery: The Macallan, Easter Elchies, Speyside, Scotland Style: Speyside Single Malt Scotch Whisky, NAS Casks: First fill sherry seasoned oak — less than 1% of maturing stock ABV: 43% Size: 750ml Explore the full Scotch whisky collection at Wooden Cork.Frequently Asked QuestionsWhat is a first-fill sherry cask?A cask that has held sherry wine and is being used for the first time to mature whisky.
