Iberian (Ibérico) black pig

The Iberian black pig is a registered breed (Cerdo Ibérico) genetically distinct from all other European pigs, traceable in unbroken lineage to the wild boars of the Iberian Peninsula. The breed has black or dark-grey skin (sometimes tinged red-brown), thin legs, a long snout, and the metabolic adaptation that defines its product value: the ability to accumulate marbled intramuscular fat at extraordinary levels (often 30%+ of body weight as fat by slaughter, vs ~14% in commodity pigs). The grading hierarchy starts with breed purity (100% Ibérico de Bellota requires both parents pure-breed verified; 50% allows Duroc-cross dams) and feed regime (bellota = acorn-fed during montanera; cebo de campo = pasture-finished; cebo = grain-finished indoors).

The fat profile is what makes the meat extraordinary: 50%+ oleic acid content (similar to olive oil), high antioxidants from acorn polyphenols, and a chemical structure that translates to translucent marbled fat at room temperature. No other commercial pig breed produces remotely similar product.
