Clamato (a portmanteau of "clam" and "tomato") is a trademark of the Mott's company which denotes a drink made primarily of reconstituted tomato juice concentrate and reconstituted dried clam broth, with a dash of high fructose corn syrup, and USDA Red 40 to maintain a 'natural' tomato colour. It is also referred to (inaccurately) as clamato juice. Clamato was produced in its current form beginning in 1969.
