Glenfiddich is a Speyside single malt Scotch whisky owned and produced by William Grant & Sons in Dufftown, Scotland. Glenfiddich means ‘Valley of the Deer' in Scottish Gaelic, hence the presence of a stag symbol on Glenfiddich bottles. Glenfiddich is the world's best-selling single-malt whisky and also the most awarded at the International Spirits Challenge.
