The Balvenie 25 Year Old Single Barrel Traditional Oak, was introduced to the Balvenie single malt Scotch whisky range in 2014. Released in batches, each bottle is one of no more than 300, drawn from a single cask, all of which are refill American oak casks. There will be slight variations between batches, but the casks selected by Malt Master David Stewart for this release are chosen for having the richly spiced, sweetly honeyed character you'd expect from 25 year old Balvenie single malt aged in American oak. This means there is an overarching consistency between batches.
