The Balvenie Thirty is a rare & especially fine single malt for which David Stewart selects only exceptional casks that were laid down over thirty years ago. By marrying The Balvenie slowly aged in traditional oak whisky casks with that aged in European oak sherry casks, David creates a rich, mellow Scotch whisky with unusual depth & complexity. ' Thirty' is bottled at 47.3% abv to capture all the signature characteristics of The Balvenie.
