David Stewart MBE, Balvenie's Malt Master, is one of the industry's most experienced experts and began working with William Grant & Sons in 1962. He is perhaps most famous for being the first to create the process that would later be known as wood finishing, a process whereby whiskies are matured in one type of cask, such as ex-Bourbon barrels, then transferred into a second cask type (such as ex Sherry, Port or Rum) resulting in a greater depth and complexity of the final flavour of the whisky. He received his MBE from Queen Elizabeth II on the 5th of July, 2016 for his services to the Scotch Whisky Industry.
