A relatively young distillery, Inverleven Distillery was built in 1938, very close to the Lowland and Highland boundary line on the banks of the River Leven in the town of Dumbarton. Established by Hiram Walker and Sons, Inverleven was originally built as a sister site to the Dumbarton grain distillery. Featuring two copper pot stills, Inverleven was thought to be the first distillery to steam-heat both its wash and low wine stills, as opposed to the regular method of the time - direct fire. In 1956, an unusual Lomond Still, which has three perforated plates that can be cooled independently allowing for different styles of whisky to be produced, was added. The stills at Inverleven unfortunately fell silent in 1991 when the distillery closed before the site was demolished in 2002 but under Gordon & MacPhail’s watchful and nurturing eye, the distillery’s legacy lives on.
