The Macallan is a renowned distillery located in Craigellachie, Scotland. It was founded in 1824 and is known for producing single malt whisky using only the finest sherry oak casks from Spain. The Macallan offers a range of expressions, with age statements ranging from 12 to over 50 years, as well as a variety of limited edition and special releases. The distillery's flagship expression is the Macallan 18 Year Old, which is matured in a combination of first-fill and refill sherry casks. The Macallan's whisky-making process is carefully controlled and includes the use of small stills, long fermentation times, and the selection of only the best casks. In 2018, a rare bottle of 60-year-old Macallan sold for a record-breaking £1.2 million ($1.5 million USD) at auction, making it the most expensive whisky ever sold.
