Glenfiddich is a Speyside single malt Scotch whisky produced by William Grant & Sons in the Scottish burgh of Dufftown in Moray. Glenfiddich means "valley of the deer" in Scottish Gaelic, which is why the Glenfiddich logo is a stag.

The 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.
