Glenfiddich 15yr Single Malt Scotch WhiskyExemplifying the Glenfiddich tradition of innovation, this 15 Year Old expression is created using a technique pioneered by the company's Malt Master. Its warm, spicy flavors are transformed with the alchemy of the Solera Vat. Aged in European oak sherry casks and new oak casks, the whisky is mellowed in the company's unique Solera Vat, a large oak tun inspired by the sherry bodegas of Spain and Portugal. Never emptied, and kept half full of whiskies
