Matured in a complex combination of casks, The Macallan 15 Y – Triple Cask Matured offers a unique character drawn from European and American sherry seasoned oak casks, as well as ex-bourbon American casks. Marrying these three types of casks is a balancing act perfectly executed by the master whisky makers of The Macallan. Aged for 15 years, this whisky represents some of the best The Macallan has to offer.
