Protected Designations of Origin (PDOs) for Iberian ham are official seals that guarantee the product's quality and origin . They ensure that the ham has been produced in a specific region, following traditional methods and adhering to strict standards regarding the breed of pig and its diet. In Spain, there are four main PDOs: Dehesa de Extremadura (temperate climate), Guijuelo (cold, dry climate, mild flavor), Jabugo (humid climate, marbling), and Los Pedroches (intense flavor). Each PDO protects the region's unique characteristics and certifies a ham of high value and authenticity for the consumer.
