The business entity Vino-Buhač is one of many wine producers that are oriented towards traditional varieties and production organized within family members, which is passed from father to son. In order to expand the capacity of the winery and the production of grapes and wine with a total production of 300,000 liters per year and an area of 27 ha of vineyards, it is necessary to develop a good marketing plan. The research showed a growing trend of demand for wines especially wines of the highest quality, which is the mission of the Buhač winery. Within the survey conducted on Google Forms according to the pattern of randomly selected citizens within five counties in Slavonia, the results were obtained according to which the marketing plan of the Vino-Buhač winery was prepared. Insufficient presence on social networks shows to be the main threat, while investment in modern wine production, luxury packaging in glass bottles and sale door-to-door with frequent promotions and tastings is more desirable among potential buyers. The expansion of production must be oriented towards the production of predicate wines, especially Ilok Traminer (late harvest) because there is a high demand for such product. Additionally, worldwide survey confirms the increase in wine consumption by consumers of all levels of purchasing power, and in particular an increase in demand of purchasing wine amongst young people. By expanding the production capacity, the business entity Vino-Buhač aims to provide areas for raising selected varieties for the production of predicate wines. The goal of this paper is to expand and improve the business entity Vino-Buhač with the purpose of ensuring a satisfactory standard of owners and workers.
