COMPLEX EVALUATION OF GRAPES FOR THE TERROIR WINES PRODUCTION

Abstract

The influence of changes in agro-climatic conditions of grape growing on the wines quality in the conditions of LLC “ITC Shabo” is studied in the paper. For the past two decades, scientists around the world have been concerned about the effects of climate change. Studies of the global climate change impact on agriculture have already covered a significant area of global food crops. Growing grapes more than growing any other plant depends on climatic conditions, soil condition, temperature in certain periods of vegetation and development. This requires a particularly careful approach to the territorial location of wine production, including in terms of varietal. As a result of research, the qualitative characteristics of red grapes: Cabernet Sauvignon, Merlot, Pinot Noir, white varieties: Pinot Gris, Rhine Riesling, Sauvignon Blanc, Chardonnay and Telti Kuruk were analyzed in order to justify production of the Shabo terroir wines. Comparative analysis of data obtained from the white and red wine materials study, allowed to establish ranges of their chemical composition variation. Compliance of wine products with the regulatory documentation requirements primarily characterizes the qualitative characteristics of wine materials. The scientific concept provides taking into account by the winemaker a set of natural, climatic conditions and agricultural techniques for a particular area of the vineyard from which the wine is produced. The main task of this approach is to maximize display and preserve in wine individual characteristics, as display of a complex of terroir descriptors with obligatory preservation of descriptors of a grape variety.
