A rich single malt matured in specially reserved sherry casks that are brought together in our unique Cask Collection Solera vat, producing this exceptionally deep and mellow whisky. To create Reserve Cask, hand-selected Glenfiddich whiskies are matured in specially reserved sherry casks. These are then married together in limited batches in our unique Reserve Cask vat to create our rich, deep and mellow single malt. The sherry casks impart layers of warm vanilla to the palate, alongside deep rich fruits and subtle oaky tannins.
