Clamato El Original tomato cocktail

Clamato is a popular commercial beverage made of reconstituted tomato juice concentrate and sugar, flavored with spices, dried clam broth, and monopotassium glutamate. It was invented in 1969 by the Duffy-Mott company in Hamlin, New York, as an attempt to create a cocktail mixer similar to Manhattan clam chowder in liquid form.

While the brand originated in the United States, it has become a cultural staple in Mexico and Canada, where it serves as a primary ingredient in drinks like the Michelada and Caesar. Today, Clamato is produced in various countries including the United States and Mexico to meet regional demand. Ownership of the brand has transitioned through several major beverage conglomerates over the decades. As of 2026, it remains a flagship brand of Keurig Dr Pepper (KDP).
