For 20 years William Grant nurtured a dream to make the 'best dram in the valley'. With the help of his family, he finally achieved that vision, building a distillery by hand, stone by stone. He named it Glenfiddich, Gaelic for Valley of the Deer. Today, Glenfiddich is just as pioneering, as this whisky shows. Aged in sherry oak casks and new barrels, this 15 year old is mellowed in a unique Solera Vat, a large oak tun inspired by the sherry bodegas of Spain. Never emptied and kept half full of whisky since 1998, the Solera Vat is the culmination of curious minds and Glenfiddich's innovative spirit. It's also the secret behind this whisky becoming the first 15 year old expression to enter the top ten bestselling single malts. Sip slowly.
