Cow milk, raw with a soured-milk starter or pasteurised with cultures, is set with rennet, cooked and left to sour under the whey for 3–5 hours. At pH 5.1–5.2 the curd is stretched, shaped by hand into a pear, firmed in cold water and brined for a day and a half per kilo. Tied with string, it ripens from one or two months to a year.

At a glance
Cow milk, raw with a soured-milk starter or pasteurised with cultures, is set with rennet, cooked and left to sour under the whey for 3–5 hours. At pH 5.1–5.2 the curd is stretched, shaped by hand into a pear, firmed in cold water and brined for a day and a half per kilo. Tied with string, it ripens from one or two months to a year. Made in 8 steps over 32 days – 12 months. The longest step, ripen, takes 30 days – 12 months (ARSIAL (Lazio regional agency for agricultura…) and runs at 4–12 °C (ARSIAL (Lazio regional agency for agricultura…).
A provolone of southern origin made across Lazio, in some makes with raw milk and a starter of milk soured in the fridge (latto-innesto). It ripens from 30 days up to a year.
Milk
Whole cow milk, raw (Latina) or pasteurised at 70–72 °C (Amatrice)
Ripening
30–60 days to 1 year; the ARSIAL description gives 60 days to 1 year
Rind
Hard, smooth, straw-yellow, deepening with age, with brownish mould spots
Size
About 3 kg or more; pear, ball, cylinder or egg, tied with string
Latina makeRaw milk, soured-milk starter, liquid rennet, cooked to 55–65 °C, aged 60–365 days at 4 °C.
Amatrice makePasteurised milk, cultures, lamb rennet paste, cooked to 45 °C, aged 30–60 days at 12 °C.
Safety
The milk is raw in some makes, such as the Latina make, and pasteurised in others, and ripening can be as short as 30–60 days. ANSES advises pregnant women, young children, people over 65 and people with weak immunity not to eat raw-milk cheeses other than pressed cooked ones such as Gruyère, because of Listeria, Salmonella and Shiga-toxin E. coli.
