Each Denomination of Origin Regulatory Board (the Spanish term "Denominación de Origen", D.O. or "Denominación de Origen Protegida", D.O.P., is normally used in English as well) establishes the norms of manufacturing of each one of the products protected by each D.O.

Each Board regulates the area of production, manufacturing process, ingredients and a number of factors affecting the products, in order to assure the authenticity of them. Note also that each Cheese with a D.O. should be numbered, making every one of them a unique item. All products protected by a D.O. must be accompanied by the logo as proof of origin, with its unique number stamped.
