Climate & terroir
Mediterranean continental — hot dry summers (35-40°C+), cold winters (sometimes below freezing), seasonal acorn drop October-March. The temperature swings and the acorn (bellota) feed cycle are the agricultural foundation for the dehesa system.

The dehesa is the cross-region wooded-pasture landscape spanning roughly 3 million hectares across western Spain (Extremadura, Salamanca, Huelva, parts of Andalusia) and Portugal's Alentejo. The landscape is human-shaped over millennia — holm oak (Quercus ilex), cork oak (Quercus suber), and grass pasture maintained at low tree density to allow grazing. The system produces acorns (bellotas) October through March (the montanera season) that free-ranging Iberian black pigs eat in volume — up to 10 kg per pig per day during the peak.

The acorn diet alters the pig's fat profile dramatically: high oleic acid content (50%+ of fat, similar to olive oil), high antioxidants from acorn polyphenols, marbled white fat that turns translucent at room temperature. All four Iberico DOP zones (Jabugo, Guijuelo, Los Pedroches, Extremadura) operate within the dehesa system, but the specific microclimate of each zone produces meaningfully different aged products.

Editorial note
The dehesa system is what distinguishes Iberico from any other cured ham — it's an agricultural-ecological landscape with no real equivalent elsewhere in cured-meat production.
