Founded in 1897 by a group of blenders based on the plans of Charles Doig, Tamdhu is one of the last distilleries in Scotland to malt all of its barley on site. Little known as a single malt, its fruity whisky is nonetheless a popular ingredient in many blended scotches, including Cutty Sark, J&B and The Famous Grouse.

A Tamdhu 8 year old single cask (#348) distilled in 2005 and bottled in 2013 by Signatory Vintage. Signatory Vintage was founded in 1988 by Andrew Symington, who previously worked at Prestonfield House, Edinburgh, where he would select casks specially for the hotel. In 2002, he bought the Edradour distillery in Pitlochry, in the Highlands of Scotland and moved Signatory Vintage vintage to the site, including the warehouses opposite the distillery. This whisky was bottled for the Un-Chillfiltered Collection launched in 2000, which features whiskies bottled at 46%, without chillfiltration, as the name implies. A limited edition of 832 bottles for La Maison du Whisky, a whisky and fine spirits importer and distributor founded by Georges Bénitah in 1956.
