Scotland, Speyside. Distillery operational. Owner: DiageoRanked “first class” by the main players in the Scotch whisky industry, Cardhu (aka Cardow) was, from the late 19th century, the leading malt of the famous Scottish dandy Johnnie Walker. Johnnie Walker & Sons bought the distillery in 1893. In response to the period of prosperity following WWII, Cardhu's production capacity was significantly increased and in the late 1960s, its owners, the Distillers Company Ltd (the future Diageo) launched an 8 year old version with a very marked sherry influence. This bottling was quickly replaced by a 12 year old version that would become the standard age statement for Cardhu, now matured in bourbon casks. In the mid-1980s, Cardhu completed its final metamorphosis and adopted its current small, square, stocky bottle. It was such a success that a major part of its production was quickly reserved for the bottling, threatening the balance on which the Johnnie Walker blend depended. The solution proposed was the release in the very early 2000s of Cardhu 12 Year Old Pure Malt (no longer a single malt). Arousing the ire of the Scotch Whisky Association, this version was phased out and has now become a collectable. Note that very few independent bottlings of Cardhu exist.

Cardhu 12 Year Old Pure Malt is a controversial version of this bottling. In 2002, in order to manage waning stocks at the distillery, Cardhu 12 Year Old briefly became a vatted pure malt. Under pressure from critics, it quickly returned to a single malt in 2004.
