These stills with spherical compartments (boil ball) play a decisive role in the crafting of the light and subtle Glenmorangie character. Only the lightest alcoholic vapours are collected. The spring waters used by the distillery are naturally filtered through limestone and impart Glenmorangie with its spicy character. The aged versions are increasingly powerful and develop delicate vanilla notes.
Glenmorangie is today an extraordinary pioneer in the art & science of oak cask maturation, and offers a spectacular choice of special finishes. Glenmorangie has a very strict policy and uses only first and second fill barrels, a process that magnifies the layers of flavours. The Glenmorangie distillate ages in ex-Bourbon, American white oak casks for at least 10 years. Glenmorangie collects a share from the ex-Bourbon casks and transfers it into casks that previously contained other alcohols or wines, thus extending the maturation: this is the “wood finish”. The use of casks that previously contained Sherry, Port, Madeira wines or Bourgogne wines maintains the essential balance of Glenmorangie whisky, while imparting intriguing characteristics to the spirit.
The art of cask maturation at Glenmorangie has been influenced by more than 25 years of research, enabling the Master Distiller to find the perfect casks for the Single Malts, and acquire the reputation of an expert amongst the circles of whisky maturation experts.
