Cardhu is a Speyside distillery near Archiestown, Moray, Scotland, founded in 1824 by whisky smuggler John Cumming and his wife Helen.[1] The distillery is now run by Diageo and the distillery's Scotch whisky makes up an important part of the Johnnie Walker blended whiskies. The word "Cardhu" derives from the Scots Gaelic Carn Dubh, meaning "Black Rock".
