Founded in Speyside in 1895, the Dufftown distillery (also known as Singleton of Dufftown for more recent bottlings, and Dufftown of Glenlivet for older bottlings) is owned by the Diageo group. It is mainly used in blends from the Bell's brand.

A Dufftown 21 year old distilled in 1975 and bottled at cask strength in 1997 for the Rare Malts series. Created in the mid-1990s by United Distillers (Diageo), the Rare Malts series features bottlings from many of the group’’s distilleries, including some of the lesser known whose production was generally used for blends, as well as closed distilleries such as Port Ellen and Brora. Bottled at cask strength, the whiskies in the range are also known for their sometimes astounding alcohol content, often exceeding 60% ABV. The Rare Malts range was discontinued in 2005.
