Fifteen-year-old Glenfiddich from three types of casks (traditional American bourbon, Portuguese sherry and new oak) is married in a large Solera vat, made of 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 and fruity nose, with delicate honey and vanilla notes. The taste is elegantly smooth, with a deep flavor that reveals fruit, gentle spice and a touch of oak. The finish is long and satisfying.
