Behold, Balvenie's fifth batch of its Tun 1509, a fantastic single malt from the distillery in Speyside, which sees a host of casks selected to be married together in the eponymous Tun 1509. For this one, the lucky casks selected to be married together were ten bourbon barrels, eight sherry hogsheads, three refill American oak casks and eight sherry butts.
