In the 1980s, Reggio's prized Vacche Rosse breed of cattle ran a serious risk of extinction. A group of breeders devised this project to encourage a reprise in the number of animals. Since 1991, production regulations establish that the fodder shall include only grass, hay and certified feed, respecting the environment and with utmost attention to animal welfare and consumer health. Besides Parmigiano Reggiano of differing ages and sizes, the company also produces butter, yogurt and ricotta.
