Mannochmore was founded in the 1960s to meet the growing demand for whisky. Primarily used to produced whisky for the Haig and Dimple blend, it is today known to collectors for its iconic black whisky Loch Dhu. This whisky, which was highly criticized for its unnatural colour when it was first released, would return sometime later on the secondary market.

A single cask (#16594) Mannochmore distilled in 1991 and bottled at cask strength in 2005 after 13 years of maturation in a sherry-style South African wine cask. 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. A limited edition of 631 bottles.
