Matured in three casks: sherry, bourbon & new oak The Glenfiddich Solera system is unique amongst Scotch whisky distillers. Fifteen-year-old Glenfiddich from three types of casks (traditional American bourbon, Portuguese sherry & new oak) is married in a large Solera vat, made from Oregon pine. The vat is always kept at least half full, ensuring a consistent quality of whisky is maintained whenever it is topped up. Then this beautifully balanced single malt is left to settle in a small Solera tun before bottling. The result? A full & fruity nose, with delicate honey & vanilla notes. The taste is elegantly smooth, with a deep flavour that reveals fruit, gentle spice & a touch of oak. The finish is long & satisfying.
