The paper examines the relationship between the use of specific knowledge and success among the Hungarian grape growers and wine makers. In the recent decade Hungary has been left behind by the world trends representing an increasing share of premium and superpremium wines (which materialize higher knowledge) in export development. According to our survey, the non-appropriate usage and management of knowledge and skills that would be ‘condition sine qua non’ for wine making might be behind that. However, the use and spread of skills is a basic component in explaining the differences among companies, it is not unambiguous in formulating the business success measured by different indicators. At the same time we can conclude that the Hungarian wine enterprises — keeping the idea of generation, as well as its further development, elaboration, and adequate usage within the frame of the company — can achieve market success.
