Founded in 1876, Glenlossie is a Speyside distillery owned by Diageo which is a key resource for production of the company's blended whiskies. The distillery itself is best known for its independent bottlings.

A Glenlossie distilled in 1966 and bottled in 1984 by Cadenhead. Cadenhead was founded in 1842 by George Duncan, who was quickly joined by William Cadenhead who renamed the business after Duncan’’s death in 1858. When Cadenhead in turn passed away in 1904, his nephew Robert Duthie took over and turned the business into the independent bottler it is today. After Duthie, it was managed by one of his employees, Ann Olivier, whose stubborn approach to running the business led to much of the stock having to be sold at auction by Christie’’s (London) in 1972 to feed the kitty and save the business. It was then sold to J. & A. Mitchell and Co, who also owned Springbank, and moved to Campbeltown. The Cadenhead “dumpy” bottles were a spearhead for the business between the late 1970s and early 1990s. There were almost 400 in total, covering most of Scotland’’s distilleries. The whiskies were bottled at 46% initially, and then at cask strength from 1989, paving the way for the Authentic Collection.
