Spirits developer and marketer Castle Brands has signed a five-year exclusive distribution agreement with single malt scotch whiskey producer Isle of Arran Distillers.

The agreement involves the distribution of the Arran Malt single malt scotch, Robert Burns single malt scotch, and Blended Scotch whiskies in the US market.
