The Glenfiddich Cask Collection whiskies - Glenfiddich Select Cask, Glenfiddich Reserve Cask and Glenfiddich Vintage Cask – have been matured in a variety of oak casks and finished in solera tuns.
According to William Grant & Sons, the solera process marries the whisky together for at least two months, until deemed ready by malt master Brian Kinsman.
The solera technique “guarantees the continuity of the whisky's flavour and taste by ensuring that the tun is never less than half full and is constantly replenished”, said the spirits company.
Kinsman said: "These latest additions to our no-age range allow us to offer single malt aficionados the best of both worlds – whiskies crafted for their flavour, alongside whiskies bottled by their age."
Glenfiddich Select Cask is described as “an elegant whisky with layers of sweetness, spice and hints of citrus, matured in hand-selected aged bourbon, European oak and red wine casks to impart a beautifully soft taste”.
Glenfiddich Reserve Cask is matured in “Spanish sherry casks used for their mellow and rich flavour characteristics” while Glenfiddich Vintage Cask is matured in European oak and American bourbon casks.
Glenfiddich Select Cask and Glenfiddich Reserve Cask will be available as global travel retail exclusives from this month; Glenfiddich Vintage Cask will be available from early 2014.
The full range will be available across all global travel retail outlets from April 2014.
