IVDP

The Port Wine Institute IVP (Instituto do Vinho do Porto) , founded by the Society of Winegrowers (Casa do Douro) and the Board of Port Wine Exporters (Grémio dos Exportadores do Vinho do Porto) in 1933, was the joint control body and lobby for all port wine until 2003. In that year, the CIRDD (Comissão Interprofissional da Região Demarcada do Douro) was integrated into the IVP. Since then, the institute has been responsible for the production of port and wines from the Douro region under the expanded name of the IVDP (Instituto dos Vinhos do Douro e Porto). The origin goes back to the "Companhia Geral da Agricultura das Vinhas do Alto Douro" (General Society for the Viticulture of the Upper Douro), which was founded in 1756 by the Marquês de Pombal (1699-1782).

The IVDP represents the interests of the winegrowers and wine merchants of the region, provides advertising and information, and promotes tourism and international trade. The head office is in the municipality of Peso da Régua and a branch office in Porto where most of the wineries and merchants are located. The Institute is endowed by the Portuguese Ministry of Finance and Agriculture with wide-ranging powers to perform public functions, in particular the establishment and monitoring of production rules. Among other things, it also determines annually which quantities of grapes may be processed into port wine. A paper seal is affixed to the neck of the bottle of each "real" port wine to certify its origin from the region and its production in accordance with the regulations of the IVDP. However, it says nothing about the exact quality.
