The Glenrothes Single Vintage 1976 is an ultra premium whiskey made with 13 barrels of the same year. A treasure without equal. On February 26, 1976, several liters of spirits were distilled at the Glenrothes distillery. Those liters went to the barrels, where they have been sleeping for several years. Those dormant barrels have been tested and tested for years, until November 18, 2015, something changed.
