There are a lot of differences between Jamón Serrano and Jamón Ibérico. It all starts with the type of pig. Jamón Serrano comes from a cerdo blanco or a white pig. This type of pork is utilized for mass production. On the other hand, Jamón Ibérico comes from a cerdo Ibérico or an Iberian pig. This type of native pig is treated specially; it even has a specific diet! When it comes to dry curing, Jamón Serrano is ready for the market after twelve months (or even less.) Jamón Ibérico does not get ready until it’s been two or three years (at least!) Because of the vast differences between the production of these Spanish hams, supplies vary, too. Jamón Serrano is more common in Spain and international markets, while Jamón Ibérico is a luxurious commodity.
