Duncan Taylor, Aged 26 Years. Now woefully bereft of life, the stills of Inverleven fell into perennial silence in 1991. Inverleven was established by Hiram Walker and Sons in 1938 at the Dumbarton complex. The site at Dumbarton is owned by George Ballatine and Son and plays host to continuous stills. This allows the production of both malt and grain whisky. The complex produces the whisky for the Ballantines blended products. Inverleven draws its water from Loch Lomond, and sits by the River Clyde.
