Characteristics and Origin of the Iberian Pig
The Iberian pigis a breed native to the Iberian Peninsula, which means it can only be found in Spain and Portugal. These two countries are the world's sole producers of Iberian ham. At Enrique Tomás, we explain why it is so special and what makes its ham truly unique.
Origins and Distinctive Features of the Iberian Pig
What animal does it descend from?
There are no 100% reliable records, but experts suggest that it carries genetic material from three subspecies: the European wild boar, the Mediterranean wild boar, and the Asian wild boar.
Where are they found?
In inland regions of Spain: northern Andalusia, Cáceres, Badajoz, Salamanca, Toledo, and Ciudad Real. In Portugal: the Algarve and Alentejo regions. Any pig with a breed purity of 50% or higher is considered Iberian.
Appearance of the Iberian Pig
Size and Color
Medium-sized with a dark coat and sparse hair. Its body is more slender and elongated than that of the white pig.
Snout and Legs
Long snout, alongside slender, long, and strong legs. Its hooves are usually black, giving rise to the popular term "pata negra" (black leg) — although in reality it is the hoof that is black, not the leg itself.
Litters
Each female gives birth to between 4 and 6 piglets per litter. When referring to a 50% Iberian pig, the mother is always purebred Iberian, while the father may or may not be. The most common non-Iberian breed used for crossbreeding is the North American Duroc pig.
Why is its meat so good?
The secret lies in its unique genetics: Iberian pigs marble fat directly into their muscles in a way no other breed can replicate. This fat infiltration makes the ham juicier, more aromatic, and gives it an incomparable texture.
Unlike white pigs, even if they participate in the free-range grazing season (montanera), their meat will not improve in the same way simply because they lack this genetic ability.
Is the curing process the same as for white pigs?
The process is the same, but significantly longer: 18–38 months for Iberian ham compared to 12–30 months for white pig ham, depending on whether the diet consisted of grain feed or acorns.
How Are Iberian Pigs Fed?
Up to 100 kg, all Iberian pigs are fed grain enriched with vitamins and minerals. Once they reach that weight, their paths diverge:
Montanera (Acorn-fed)
The pig roams the oak pastures (dehesa) eating whatever it finds: acorns, chestnuts, cork oak seeds, and grass. Exercise combined with a natural diet allows fat to infiltrate the muscle, resulting in acorn-fed Iberian ham (jamón de bellota), the highest quality available.
Cebo (Farm-fed)
The pig remains on the farm with a diet based on vitamin-enriched grain feed. This produces grain-fed Iberian ham (jamón de cebo). The choice depends on the type and quantity of hams the producer wishes to yield.
Many factors make the Iberian pig unique, making the ham produced from it equally extraordinary. Enjoy it whenever you get the chance!
