It is one of the major assignments of the organisation to guarantee the protection of origin. Therefore it regulates and controls planting as far as location, variety and other specific regulations are concerned. Through preparing and controlling the implementation of rules for the wine communities, it regulates those factors of grape and wine production and partly even of trade, which have major importance and largest impact on the quality. It is the head of the wine community that issues the certificate of origin for each quantity of grape produced, which is the basis in the control of the origin of the wine.
