Single cask whiskies are a speciality of the Pitlochry-based independent whisky bottlers Signatory Vintage. Founded in the late 1980s by Andrew Symington, whose first trade purchase was a cask of Glenlivet distilled in 1968, Signatory Vintage has been bottling single cask single malt whiskies since 1989 and the company has built a reputation for outstanding independent single cask whiskies ever since.

Today, Signatory Vintage is one of Scotland’s most important independent whisky bottlers, and the vast majority of the company’s releases are single cask whiskies of the very best type. Signatory's single casks are bottled without colouring or chill filtration, either at natural cask strength or diluted to 46% if the whisky is judged to drink better at a slightly lower strength.

Signatory Vintage’s single cask whiskies are in a class of their own, and no self-respecting whisky fan’s whisky cabinet should be without at least one example.
