In 1959, eight dairies in the Parmigiano Reggiano area founded the CCS Consorzio Caseifici Sociali. Over the years, the business has expanded to include the production and maturing of Parmigiano Reggiano.
In 1995, the Granterre Consortium was established, bringing together the entire Parmigiano Reggiano dairy chain, and then almost ten years later, in 2004, control of Parmareggio Spa was acquired. In 2019 Bonterre Spa, the holding company under which the control of Parmareggio Spa and Grandi Salumifici Italiani Spa (controlled by UNIBON) was established.
