Side-by-side or overlay PDF diff driven by one engine that reads each file into a structured model — text, vector geometry, images, form fields, annotations — and compares the models. Moves show as moves, edits show only where they happened, and any PDF type works without picking a mode.

Whole ewe milk is set with calf or lamb rennet in 20–30 minutes, at 36 °C for the soft type from pasteurised milk or 39 °C for the semi-hard type from raw or thermised milk. The curd drains in cascine moulds, is stoved and dry-salted every 12 hours for one or two days. The soft type ripens 30 days to 3 months with an oiled rind; the semi-hard type ripens 3–12 months under a grey-green natural mould.

Whole ewe milk is set with calf or lamb rennet in 20–30 minutes, at 36 °C for the soft type from pasteurised milk or 39 °C for the semi-hard type from raw or thermised milk. The curd drains in cascine moulds, is stoved and dry-salted every 12 hours for one or two days. The soft type ripens 30 days to 3 months with an oiled rind; the semi-hard type ripens 3–12 months under a grey-green natural mould. Made in 6 steps over 31 days – 12 months. The longest step, ripen with washing, takes 30 days – 12 months (Disciplinare di produzione del Pecorino dell'…). Selected or natural lactic cultures in whey or ewe milk from the area, advised for all types does most of the fermenting.
The rules set two types from ewe milk, a pasteurised soft cheese and a raw or thermised semi-hard one. The semi-hard cheese must grow natural grey-green moulds on its rind, and no anti-mould agents are allowed.
Rind
Pale white-yellow (soft) to brown with grey-green moulds (semi-hard)
Size
1.0–2.5 kg; cylinder, Ø 15–22 cm, side 7–11 cm (never above half the diameter)
Composition
Fat in dry matter at least 45 % (fresh) or 40 % (aged)
Season
Made mainly March to September, but allowed all year
Pasta teneraPasteurised milk; ripened 30 days to 3 months; oiled rind.
Pasta semiduraRaw or thermised milk; semi-cooked; ripened 3–12 months with natural grey-green moulds.
Safety
The soft type uses pasteurised milk and may be sold after 30 days; the semi-hard type uses raw or thermised milk and may be sold only after 90 days. In a challenge study, E. coli O157 added to raw ewe milk was still detectable in pecorino after 90 days.
Hazards the sources name: Escherichia coli O157 in raw ewe milk; in a challenge study it was still detectable in pecorino after 90 days of ripening.
ONAF's sheet says sheep and goat flocks dominated the Reggio Apennines from the start of the 11th century, and that abbey records until the 15th century mention cheese made from sheep milk. In 1800 the agronomist Filippo Re counted 67,000 sheep in the Reggio area, but by the end of that century dairy cows were favoured and sheep numbers fell. A shepherds' league (Lega dei pastori) was founded on the Reggio Apennines in January 1921. The mountain community still had over 19,000 sheep in 1982, mostly milk sheep, and under 5,000 by the early 2000s. ONAF puts the number of shepherds with milk sheep at about thirty.
