The Denominations of Origin (DO) for Iberian ham are official seals that guarantee the quality and origin of the product. They ensure that the ham has been produced in a specific region, following traditional methods and complying with strict standards regarding the pig breed and its diet. In Spain, there are four main DOs: Dehesa de Extremadura (temperate climate), Guijuelo (cold and dry climate, mild flavor), Jabugo (humid climate, fat infiltration), Los Pedroches (intense flavor). Each DO protects the regional uniqueness and certifies a ham of high value and authenticity for the consumer.
