Glendullan produces a green, grassy spirit through long fermentation and slow distillation, which gives it a lightly fruity character. The distillery is situated on the banks of the river Fiddich and uses a combination of stainless steel and wood for fermentation. Glendullan’s whisky is primarily bottled as a single malt under the Singleton brand.
The distillery was originally built in 1897 by William Williams, an Aberdeen blender and broker, who had an exclusivity agreement with Glenfiddich. After merging with Greenlees Brothers, Glendullan was absorbed by DCL (Distillers Company Limited) in 1925. A second distillery was constructed next door in 1972, and for a time, both sites operated together. However, the original distillery was closed in 1985, and “Glendullan 2” became the active site, providing whisky for blends and the Singleton of Glendullan brand, which was launched in 2007 for the North American market.
In 2014, a bioplant was introduced on-site to process the spent lees, contributing to sustainability efforts.
