Although Graševina is the variety of Central Europe, some foreign authors believe that her homeland Slavonia and Croatian Danube because it is in this area gives excellent results in terms of quality wines. The aim of this study was to examine the presence of information about Graševina on the Internet with a focus on Graševina produced in Croatia and online marketing activities of Graševina winemakers and the National Association Graševina Croatica. A special part of this work is bilingual web site on the Internet at www.grasevina.org which represents online database about Graševina in Croatia with detailed information of all members of the associatio.
