Marcial Castro is a family-owned company based in Guijuelo, Salamanca, with over a century of expertise in producing premium Iberian pork products. Their Jamón de Bellota 100% Ibérico ORO stands out as a flagship product, reflecting their dedication to quality and tradition.

This exceptional ham is derived from purebred Iberian pigs raised freely in the dehesas, where they forage on acorns, natural grains, roots, and herbs. This diet imparts a distinctive flavor and texture to the meat, characteristic of the finest "pata negra" hams.

The curing process is conducted artisanally, utilizing the cold, dry air of Guijuelo to develop the ham's unique qualities. Notably, this product is certified under the Denominación de Origen Protegida (D. O.P.) Guijuelo, ensuring adherence to stringent quality standards and authentic production methods.
