After the success of the Balvenie Tun 1509 Batch 1, Balvenie's Malt Master David C. Stewart MBE had selected 32 of Balvenie finest casks – 23 American oak casks and 9 European oak Sherry casks and transferred them all together in a large tun for the marrying process, allowing them to blend beautifully for few months, before bottling.
