About Rio Mare

Rio Mare is the largest canned fish brand in Italy and in Europe, and the product that turned Bolton from a distributor into a manufacturer. Launched in 1965, it sold tuna — until then mostly bought fresh — in single-serving cans, which created a category rather than entering one. Its plant at Cermenate became the biggest tuna cannery in Europe, and the brand runs long-standing sustainability partnerships with WWF and Oxfam.
