On this page you can view our collection of Macallan Anniversary Malt special releases. These 25 year old malts first emerged in the 1980's, filled from 1950's casks, and new releases continued for around 20 years up to around the start of the new millennium. With a lot of these expressions extremely rare, coupled with the fact they are vintage 25 year old Macallan's, the Anniversary Malt's have become somewhat of a collectable phenomenon.
