The Tamdhu whisky is almost completely used for the production of blended whiskies, such as The Famous Grouse, J & B and Cutty Sark. Tamdhu's traditional single malt bottling does not mention its age, but a recent addition to its product line includes a 10-year-old distillery bottling. Other single malts are sold by independent bottlers.
It was announced that as of April 2010, the Tamdhu Distillery, belonging to the Highland Distillers subsidiary of the Edrington Group, was being closed and the plant shuttered. It was then sold to Ian MacLeod Distillers in June 2011, who recommenced production of single malt in May 2013
