Cheese from Spain, Asturias
A simple fresh cheese of eastern Asturias, once sold at coastal markets. Cow milk, or sheep or goat milk in spring and early summer, is set with rennet, cut small and lightly pressed, then rubbed with salt on both faces. The ministry catalogue describes it as fresh and unripened, soft, moist and mild, with a pH of about 6; it names cultures only for pasteurised milk, so little fermentation is documented.

Total time across the recorded steps: 3 days
What changes: Starting material: cow milk, or sheep or goat milk in spring
Farms were mixed, mostly cattle with a few sheep and goats, so most cheese was cow milk, with sheep or goat cheese in spring and early summer.

The ministry catalogue describes it as fresh and unripened, soft, moist and mild, with a pH of about 6; it names cultures only for pasteurised milk, so little fermentation is documented. Made in 5 steps over 3 days. The longest step, cut and drain in the mould, takes 3 days (Asociación de Queseros Artesanos (Asturias)). Salt is 2 % (Ministerio de Agricultura (MAPA) 2015).

Queso de Porrúa is a plain market cheese, only lightly pressed and salted on its faces. Its milk changes with the season, from cow milk most of the year to sheep or goat milk in spring.
The ministry catalogue describes a fresh, unripened cheese with a pH of 6.0 and about 2 % salt, made from raw or pasteurised milk, with lactic cultures added when the milk is pasteurised. If the milk is raw, the CDC says people at higher risk, including pregnant women, people 65 or older and people with weak immunity, should avoid raw-milk cheese unless it is heated to 165 °F (74 °C) or until steaming hot.
Every number is labelled with how it is known. How this atlas is made
The ministry catalogue says it was a homemade cheese sold at the local markets of the eastern Asturian coast. Growing demand moved production into small specialised dairies. A 2007 book on the artisan cheeses of eastern Asturias describes a Porrúa maker, Emérita Romano, making the fresh cheese from cow milk of the La Mañanga pastures, with the marks of the mould on its surface, and notes that Porrúa cheeses also exist in cured cow and goat versions.
