Whole ewe milk, sometimes with a selected lactic culture, is warmed to about 35 °C and set with calf rennet. The curd is broken to rice-grain or hazelnut size, ladled by hand into baskets, dry-salted and ripened from two weeks to eight months. The rind is often protected with olive oil or tomato paste.
Total time across the recorded steps: 15 days – 8 months

Whole ewe milk, sometimes with a selected lactic culture, is warmed to about 35 °C and set with calf rennet. The curd is broken to rice-grain or hazelnut size, ladled by hand into baskets, dry-salted and ripened from two weeks to eight months. The rind is often protected with olive oil or tomato paste. Made in 5 steps over 15 days – 8 months. The longest step, ripen in a farmhouse room, takes 15 days – 8 months (Regione Emilia-Romagna 2025). Selected lactic cultures, when used does most of the fermenting.
The milk may be raw. In a challenge study, E. coli O157 added to raw ewe milk was still detectable in pecorino after 90 days of ripening, so clean milk matters. ANSES, the French food safety agency, says Listeria and enterohaemorrhagic E. coli in raw-milk cheeses can kill. It advises pregnant women, people with weak immunity, people over 65 and young children to avoid raw-milk cheeses, except cooked pressed cheeses such as gruyère or comté; its page does not name pecorino. It adds that raw-milk cheese well cooked, as in an oven dish, no longer poses a risk.
Hazards the sources name: Escherichia coli O157 in raw ewe milk; in a challenge study of pecorino, not this cheese, it was still detectable after 90 days of ripening.
Historical research cited by ONAF finds sheep cheeses widely made in the Romagna hills from the 16th century. Sheep farming shrank until the 1950s, when shepherds from Sardinia settled in the area and revived it. Flocks spend winter on the plain, often towards the Adriatic coast.
