The Balvenie 30 Year Old is a rare and especially fine single malt for which Malt Master David C. Stewart MBE selects only exceptional casks that were laid down over 30 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 aged whisky with unusual depth and complexity. 'Thirty' is bottled at 47.3% ABV to capture all the signature characteristics of The Balvenie.
