The Macallan Triple Cask Matured 12 years old is created from a trinity of spirits, matured individually in European sherry seasoned oak casks, American sherry seasoned oak casks and American ex-bourbon oak casks. Once filled, the maturing spirit remains undisturbed in the same casks for 12 years, after which this complex combination of casks is exquisitely and expertly married together to create this vibrant single malt.
