A Marche pecorino of raw ewe milk, already ripened for 40–60 days, is wrapped in walnut or chestnut leaves, or layered with herbs or grape pomace, and shut in oak casks, barrels or vats for 20–90 days to ferment again. After the cask is opened the cheeses air on wooden boards for at least 10 days.
The base-pecorino sheet allows added lactic cultures if they do not change the typical character of the cheese.
Total time across the recorded steps: 2.4 months – 6.3 months

At a glance
A Marche pecorino of raw ewe milk, already ripened for 40–60 days, is wrapped in walnut or chestnut leaves, or layered with herbs or grape pomace, and shut in oak casks, barrels or vats for 20–90 days to ferment again. After the cask is opened the cheeses air on wooden boards for at least 10 days. Made in 6 steps over 2.4 months – 6.3 months. The longest step, ripen before the cask, takes 40 days – 3 months (Regione Marche 2014).
The cheese is not made differently; it is finished. A two-month pecorino is shut in oak casks with walnut or chestnut leaves, herbs, pomace or wine for 20–90 days so it ferments again, then aired on boards.
Milk
Raw local ewe milk (the base Marche pecorino)
Ripening
40–60 days (90 if wine is used), then 20–90 days in the cask and at least 10 days of airing
Rind
Dark, thin, printed with leaves, with moulds; reddish with red pomace
Size
Medium and small wheels preferred; the base pecorino is 1–2.5 kg, ø 14–20 cm, 6–10 cm high
Alle erbeLayered with savory, nepitella, bay and thyme.
In vinacciaLayered with grape pomace; reddish rind with red grapes.
Nel vinoSubmerged in Verdicchio or local red wine after 90 days of ripening.
Safety
The base pecorino is made from raw milk. 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, and advises pregnant women, people with weak immunity, people over 65 and young children to avoid raw-milk cheeses other than cooked pressed ones such as Gruyère or Comté.
