Founded in 1825, the Highland distillery Glencadam remained for a long time in the shadows. Its whisky was used in several blended whiskies, including Ballantine's. It was only at the start of the 21st century that the new owner, Angus Dundee, decided to bottle its single malt, much to the delight of enthusiasts.

A Glencadam distilled in 1979 and bottled by Scottish independent bottler Signatory Vintage after 16 years of maturation in a sherry 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. Here, it ages whiskies from all over Scotland, at cask strength or lower, using neither chill filtration nor artificial colouring.
