The Balvenie Distillery matures its whisky in casks from various parts of the world, but this limited edition SherryOak has been matured solely in European oak butts - brought from the bodegas of Spain and previously used to mature rich Oloroso sherries. This limited edition is a rare treat for the Balvenie enthusiast. There exist only a couple of examples of The Balvenie matured solely in sherry casks - most famously Cask 191 - a 50 year old which yielded just 83 bottles in 2002 and - at £6,000 a bottle - has been enjoyed by a privileged few. The Oloroso sherry casks were filled and laid down in Warehouse 21 over 17 years ago. The result pays homage to the casks' southern Spanish origins - a rich and intense single malt, characterised by mixed spice and sweet sherry fruitiness.
