Wm. Cadenhead is Scotland’s oldest independent bottler, founded in 1842 by George Duncan. His brother William Cadenhead joined the company in 1952, taking over after George’s death in 1958. The company got into the whisky bottling business after 1904, when his nephew Robert Duthie took over, and since its sale to J&A Mitchell in 1972, Wm. Cadenhead has become on of the most sought after names in whisky. Its Authentic Collection is the flagship brand, but the portfolio of the company has expanded in recent years with labels like this.

Glen Spey is the historic home of the Gilbey's 'Spey Royal' blend, and currently provides the majority of its output to J&B, an arrangement in place since its acquisition by IDV in 1962. It was briefly available as a single malt in the 1980s, and Diageo launched an official distillery bottling in 2001 as part of the Flora & Fauna range. Outside of this however, it is a rarely seen single malt.
