Part of the 2019 'Rare by Nature' Special Release series from Diageo. This heavily sherried Mortlach was matured in first fill Oloroso and Pedro Ximenez Sherry casks for 26 long years. An astonishingly rich and decadent whisky that is reminiscent of an ancient Cognac. Only 3,883 bottles individually numbered bottled were produced. Bottled at a natural cask strength of 53.3% ABV.
