Back in 1978, the agricultural company Porretta Enzo was founded, with the cultivation of mushrooms in caves in Tivoli, on the initiative of the owner, who initially dedicated himself to the cultivation of mushrooms. With the increase in production, in 1985, the first plant for the storage and sale of mushrooms in boxes was built in San Cesareo and, only 4 years later, the first factory in Italy for the processing of mushrooms was established nearby and in 1991 it was transferred to a larger plant in Rocca Priora.
In 1995, a new plant was built, including two processing lines and a mushroom factory for the cultivation of pleurotus mushrooms. In that year the company extends its sales throughout Italy and had 30 employees.
