The Research Institute of Viticulture and Enology (RIVE) was established in 1924. It is the oldest research institute in Slovakia. The main reason for its establishment was to contribute to revitalization of vitiviniculture in Central Europe. The situation was critical as of invasion of phyloxera, plasmopara viticola and grape mildew at the beginning of 20th century. The RIVE was founded in the place of former Ugrian Royal viticultural school as a predecessor of the contemporary RIVE.

The Institute consisted of four departments: controlling, experimentation, operations and advisory service. In 1931-1945, when new varieties were beginning to cultivate, experts observed its adaptation affinity, influence on fertility and grape quality. The first clone materials of well-known grape varieties were extracted - Grüner Silvaner, Welschriesling and Traminer and the first ampelopsis graphic studies were created. In the field of wine technology the most of attention was paid to cloudiness elimination and wine stabilization. Since 1949, the key research has been oriented at genetics, physiology, ecology, biochemistry and enology. Vitivinicultural research was aimed at increase of technological level and quality of grape processing and wine production. Societal and economic changes in 1989-1990 caught this branch, as well as whole agriculture and food industry, unprepared. As a consequence, there has been decreasing interest at vineyard cultivation.
    
The goals of todays research:

  • Molecular biology and genetic of vine as a component of maintenance, improvement and reproduction of the basic genetic sources. Development of methods for determination  of pathogenic diseases in vine.
  • Innovation Technologies aimed at environmental goals and production effectiveness. In Slovakia numerous studies have been performed on premature decline of young vines due to the fungal pathogens - Petri disease. The goal of the study is to describe observed internal and external symptoms, to determine reason of this premature decline and to minimize economic losses.
  • Development and verification of methodsidentifying unlicensed enological practices (wine adulteration) using aroma compounds analysis by GC MS and HPLC.
  • Authentification of wine in light of varieties, terroir and other factors. For authentification is used original method - headspace  analysis of volatile compounds over the liquide, protected type N. 3183 (2002), that provides high reproducibility (3-4%) for more than 100 statements, which are suitable for mathematical processing.
  • Representation of Slovak republic and active expert works in Wine and Vine International Organisation (O.I.V) in Paris.
