Iberico cheese is produced only in the province of Valladolid in central Spain. In order to maintain some semblance of order and control of its large cheese production the Spanish government created the Denominations of Origin Certification. This designation controls the name, area, and standards of production to insure a consistent quality product. Iberico is not yet DOC certified but it has applied for certification and hopes to receive it soon. However the dairies that produce this cheese have maintained their own high standards and guidelines since 1987.
