Calvo Canned Tuna

Calvo is a flagship Spanish brand specializing in canned seafood. Founded in 1940 by Luis Calvo Sanz in Carballo, Galicia, the company revolutionized the market by introducing the 'pack of three' format and vertical integration in the fishing industry.

Today, Calvo operates under the umbrella of Grupo Calvo (officially Nauterra as of late 2023), which remains a major global player in the seafood industry. While its spiritual and corporate home is Spain, the company has massive industrial complexes in El Salvador and Brazil to facilitate global distribution. The brand is a staple in Spanish households and is widely exported across Europe and Latin America.
