This single malt has been matures exclusively in a refill American oak cask for at least twenty one years. Out Malt Master carefully samples the aged whisky, cask by cask. He will select only single malt characterized by subtle spices and a rich honeyed sweetness to be bottled as The Balvenie Single Barrel Traditional Oak. The craft of whisky-making and the alchemy of cask, spirit and time are embodied perfectly by The Balvenie Single Barrel. Each cask tells its own story and its yield is, by nature, one of a kind.
