A rich and decadent limited-edition single malt from Glenfiddich, Cumulative Time is a 40-year-old whisky made by combining specially-selected butts and hogsheads with the distillery's marrying tun, that contains some of the previous batches of impressively-aged whisky. The preparation and aging process of this whiskey is extremely complex. Initially kept in American oak barrels, then moved to European oak barrels that matured sherry, Glenfiddich 40 years borrowed from the refinement of these essences. The bouquet of this unique malt is not only complex, it is a symphony for all the senses.

The bottle is presented in a handmade jesmonite box, each one unique and unable to be perfectly replicated due to the subtle markings of the jesmonite, and each bottle is sealed with a striking jesmonite stopper.
