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.HistoryThe Glenfiddich Distillery was founded in 1886 by William Grant in Dufftown, Scotland, in the glen of the River Fiddich. The Glenfiddich single malt whisky first ran from the stills on Christmas Day, 1887.In the 1920s, with prohibition in force in the USA, Glenfiddich was one of a very small number of distilleries to increase production. This put them in a strong position to meet the sudden rise in demand for fine aged whiskies that came with the repeal of prohibition.In the 1950s, the Grant family built up an onsite infrastructure that included coppersmiths to maintain the copper stills, and a dedicated cooperage that is now one of the very few remaining in distilleries. In 1956 the Grant's brand launched the now-iconic triangular bottle, designed by Hans Schleger.Following difficult times in the 1960s and '70s, many small, independent distillers were bought up or went out of business. In order to survive, W. Grant & Sons expanded their production of the drink, and introduced advertising campaigns and a visitors' centre. In this period they also took the decision to begin marketing single malt as a premium brand in its own right, effectively creating the modern single malt whisky category.
