The GlenDronach Cask Strength offers connoisseurs a deeper insight into the distillery's signature profile, by bottling the whisky at its natural cask strength of 61%. The eighth release of this expression has been matured for ten years in both Pedro Ximénez and Oloroso sherry casks, resulting in an exquisitely rich and full-bodied Single Malt, with the full depth of the long maturation in Spanish oak.
