The Balvenie Single Barrel First Fill has been aged in a first fill, ex-bourbon cask for at least 12 years. Almost all Scotch Whisky is matured in casks previously used by Bourbon distillers. When brought to Scotland and used for the very first time they are known as 'First Fill'. Our Malt Master samples the aged whisky, cask by cask and selects only those characterised by sweetness and subtle vanilla oak to be bottled as The Balvenie Single Barrel First Fill. A series of "limited editions" - Each bottle is one of no more than 300 drawn from a single cask and each is hand-numbered and carries the number of the cask in which it matured. Dr Andrew Forrester, UK Brand Ambassador says: "As no two casks will ever produce the same whisky and there are no more than 300 bottles from any single cask, every batch of The Balvenie Single Barrel First Fill will have a unique identity. Due to the experience David Stewart has from over 50 years at The Balvenie however, we can expect a consistent character to this dram and boy, it is a good one".
