Casciotta d'Urbino is a small, soft, fresh cheese made from whole ewe milk (70–80%) mixed with cow milk. The milk, raw or pasteurised, is set at about 35 °C with calf rennet, the curd is cut to hazelnut size and shaped by hand in moulds into a low, round-edged cylinder. Salted dry or in brine, it ripens only 15 to 30 days. Made in 6 steps over 15 days – 30 days. The longest step, ripen briefly, takes 15–30 days (European Commission 2020) and runs at 8–14 °C (European Commission 2020). The milk's lactic bacteria, with optional added lactic cultures; natural gas production makes the few small eyes does most of the fermenting.

What makes this one different
Casciotta d'Urbino is a short-ripened mixed-milk cheese with ewe milk dominant and cow milk making up the rest, a mix the specification ties to the small family flocks and herds of the area. It is shaped by hand in moulds once made of local terracotta and majolica. The 2020 amendment dropped the label "semi-cooked", which did not fit the cheese.
Composition
Fat in dry matter at least 45%
Size
12–16 cm across, sides 5–9 cm high, 800–1,200 g; rind about 1 mm
Ewe and cow herds were kept year-round in the area from the 1500s, when the dukes of Montefeltro and della Rovere discouraged transhumance. ONAF cites a 1590 letter sending four of these cheeses to the Duke of Urbino, and tells that Michelangelo bought farms near Casteldurante to keep it on his table. It became an Italian DO in 1982 and an EU PDO in 1996.
