Once people were self-sufficient, markets were established where all the local cheeses were sent (that of Grado deserves a special mention). This, coupled with the gradual progress in communications, has allowed trade to expand beyond the borders of the production area and beyond Asturias.
L'instauration des marchés, et notamment celui de Grado, où, lorsque la production excédait l'autosuffisance, tous les fromages de la zone convergeaient, et l'avancée progressive des communications ont permis l'expansion commerciale au-delà des limites du territoire de production et des Asturies.
