Today the Hungarian vine- and grape industry uses two official databases. The site cadaster of the grape registers and qualifies those sites that are suitable for vine growing. This registry system has been applied since the early 1980s. The cadaster also constitutes the base of the currently operative classification of the vine-districts in Hungary. Only the sites rated class “1” or class “2” are suitable for planting of vines, with the exception of the vine-districts in the Alföld, where planting in the class “3” sites is also approved.

The other database is built upon the data provided by the vine-growers on a compulsory basis. The compulsory professional administrative bodies of the vine-growers, the vine-growing communities, have managed this database. The members of the vine-growing communities are obliged to provide the data to the vine-growing community on vineyards, vine-cellars and the yearly output figures. These data are essential for issuing the documents of origin regarding the grape and wine produced.

The objective of the research is the combined analysis of the given oecological conditions and the vine growing, in other words, the investigation of the influence of the environmental complex to the quality and the economical potentialities of the vine-growing.

The cadastral rating and the yield results (Nagyréde)

The other tasks of the analysis are to determine the correct method of using the industrial databases – that were only used for registration purposes earlier – for finding the optimal growing sites and to measure the level of utilisation of the oecological potentialities.

The results are provided to the potential users by Internet.

• The comparison of the site cadaster and the production data – after further clarifications – can definitely be used for partial analysis of the potentiality of the site

• It can be stated that the regression is the most powerful among the yield result and the land type , as well as the complex site ratios (value number of the site, cadastral rating)

• It is necessary to continue the analysis by the way of using higher number of items in the specimen (including more locations) and examining the differences among the vintages.

• It can be stated that a significant part of the vine-growing area (especially in the Alföld) is not located in the site optimum or in areas with good cadastral rating.
