Whisky Glenfiddich Reserve Cask. Matured in distinctive Spanish sherry casks to create a rich and mellow flavour, each individual cask is hand-selected for its flavour profile by our Malt Master, Brian Kinsman. Once selected, casks are married in our unique Solera vat, allowing their complementary flavours to get to know each other and meld together to create a single malt of extraordinary consistency and quality. Deliciously smooth and silky, this expression has a sweet, spicy taste and a complex flavour that develops with each sip. A truly intriguing single malt.
