Casearea Agri is based in the Tiber river valley, near the Nazzano Tevere Farfa Nature Reserve, in a landscape surrounded by hills and pastures. The producer has long stood out for a time-honored tradition of making sheep's milk cheese with a view to bringing out its rich sensory qualities and nutritional properties. To produce Lazio Pecorino Romano Dop, only rennet and salt are added to the sheep's milk. What makes the difference is respect for the rhythms of nature, still lush here in the valley. All dairy products are made with entirely natural ingredients, such as pure sheep's milk, rennet, salt and select lactic ferments. Various flavored cheeses are also produced.
