Raw sheep milk, sometimes with a little goat milk, is stirred and set with liquid calf rennet, and the uncut curd drains in sieves. It is put in moulds, salted dry by hand and kept a few days in small airy rooms; about 4–6 days pass between forming and sale.

Raw sheep milk, sometimes with a little goat milk, is stirred and set with liquid calf rennet, and the uncut curd drains in sieves. It is put in moulds, salted dry by hand and kept a few days in small airy rooms; about 4–6 days pass between forming and sale. Made in 4 steps over 4 days – 6 days. The longest step, mature briefly, takes 4–6 days (Regione Liguria (agriligurianet)).
Made from raw milk and sold after about 4–6 days, so it is not aged. The US FDA says even ageing raw-milk cheese for 60 days may not remove E. coli O157:H7 and Salmonella, and Listeria may grow in some cheeses while they age. The CDC says people at higher risk, including pregnant women, people 65 or older and people with weak immunity, should avoid raw-milk cheese unless it is heated to 165 °F (74 °C) or until steaming hot.
The regional sheet notes that Pantaleone da Confienza, physician to the House of Savoy, ranked the robiole of the Del Carretto mountain lands, the Val Bormida, among the best in his treatise on dairy foods. Milk could not be sold fresh, so cheeses, robiola the most typical, were part of the winter food store.
