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 12 year old single cask Tamdhu (#1999) distilled in 1994 and bottled in 2006 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 to the site, including the warehouses opposite the distillery. A limited edition of 642 bottles.
