To create the much-anticipated The Balvenie Tun 1509 Batch No. 3 Malt Master David C. Stewart MBE drew on his extensive knowledge and expertly hand-selected 31 of the finest casks from the distillery's precious aged whisky stocks. He used 12 sherry butts distilled between 1989 and 1992, 11 American oak hogsheads distilled in 1989 and eight refill American Oak butts distilled in 1992 and 1993.

All were transferred to the single marrying vessel, which for several months sat in Warehouse 24 before bottling. This is a rare interpretation of the marrying process, allowing all 31 casks to come together in a unique expression of The Balvenie that's greater than the sum of its constituent parts.
