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.
Open a STEP / STP part and it measures itself — volume, thinnest wall, draft and undercut checks on load, plus hole detection with a BOM. Measure, section, export STL. Rust + WASM B-rep kernel, runs in your browser.
Raw cow, sheep or goat milk, alone or mixed, is curdled at 22–30 °C, cut small, moulded and dry-salted. The fresh cheeses are smoked over native hardwood until the rind turns burnt sienna, then ripen in limestone caves, where Penicillium from the cave may creep in from the rind as faint blue-green streaks. Made in 6 steps over 2 months. The longest step, ripen in limestone caves, takes at least 2 months (European Commission 2024) and runs at up to 12 °C (European Commission 2024). Lactic acid bacteria of the raw milk and Penicillium from the caves, which may bloom blue-green in the paste near the rind do most of the fermenting.

Raw milk of cow, sheep or goat, alone or mixed · From registered herds fed mainly by grazing; del Puerto cheese must mix two or three kinds[gamoneu-spec2024]
Animal rennet or another authorised milk-clotting enzyme[gamoneu-spec2024]
Salt (sodium chloride) · Rubbed on the top and bottom faces[gamoneu-spec2024]
Ash, heath, beech or other native hardwood · For smoking[gamoneu-spec2024]
No added moulds · Fungi and yeasts must come from the ripening caves, never added to the milk[gamoneu-spec2024]
Starter: the raw-milk flora sours the milk; Penicillium and yeasts come from the caves

What makes this one different
Gamonéu is smoked before it goes into the cave, and no mould is ever added. Any blue comes only from cave Penicillium working in from the rind, so it stays a faint edge instead of the full veining of Cabrales.
Milk
Raw cow, sheep or goat milk, alone or mixed
Paste
Hard or semi-hard, crumbly; at least 45 % fat and 25 % protein in dry matter, at least 55 % dry matter, pH 4.5–6.5
Ripening
At least 2 months from curdling (3 months over 7 kg), with at least 30 days in a cave
Gamonéu del PuertoMade in summer in small mountain-pass dairies of Cangas de Onís and Onís, from a mix of two or three milks of herds grazing listed high pastures.
Valley GamonéuCheese made outside the del Puerto rules. The earlier specification labelled it del Valle; the 2024 amendment keeps only the del Puerto term.
Safety
This is a raw-milk cheese. ANSES advises pregnant women, young children, people over 65 and people with weak immunity not to eat raw-milk cheeses other than cooked pressed ones such as Comté; Gamonéu is uncooked. Cooking the cheese removes the risk.
Hazards the sources name: Listeria monocytogenes, Salmonella and Shiga-toxin-producing E. coli (risks ANSES names for raw-milk cheeses).
A letter to King Philip IV in 1641 about grazing land says the cheese fed the poor of the district, and Madoz's geographical dictionary mentions it as a staple. Herders far from markets turned their mixed-flock milk into cheese and ripened it in the mountain caves. The area became Spain's first national park, Montaña de Covadonga, in 1918.
