Tamdhu is a Speyside distillery in Aberlour that was established in 1897. Although it has the big, bold shadow of Macallan neighbouring it, both of these malts contribute to the Famous Grouse blends, though Macallan has always had the better fortune when it comes to single malts. Tamdhu shares its name with a station, which ran up and down the valley. Characteristics: Mild and sweet.
