The Balvenie DoubleWood is a 12 year old single malt which gains its distinctive character from being matured in two woods. Over its period of maturation it is transferred from a traditional oak Whiskey cask to a first fill European oak sherry cask. Each stage lends different qualities to the resulting single malt ~ the traditional casks soften and add character, whilst the sherry wood brings depth and fullness of flavour. - The Balvenie Distillery
