There are many different types of ham: Italy's most famous is "Prosciutto di Parma," France has Ardenne Dry Ham and Bayonne Ham, while Portugal's best-known is "Presunto." However, none of these has achieved the same level of international recognition as Jamón Ibérico de Bellota (acorn-fed Iberian ham), which is only produced in Spain. The different breeds of pig used are all descended from Iberian stock. These breeds, combined with an acorn-based diet and the process of maturing the meat, give this product its exceptional flavor and nutritional value.
