At the "Magarach" institute the work on definition of methodical approach to technological assessment of the introduced clones of classical red grapes is carried out with a view of their possible use for production of high-quality wines. The object of research are the red table dry wine materials produced by use of various processing methods (classical technology, and method of carbon dioxide maceration of pulp and grapes). The methods of research used in the work are the standardized and special uvologic, physical and chemical, biochemical, organoleptic and statistical, with use of the modern equipment and the computer technics. For a complex assessment the research of grapes clones in "grapes - mash - wine material" system are carried out. As a result of carried out research the possibility of growth of the introduced red clones (Cabernet Sauvignon, Cabernet Fran, Merlot, Sira) under the conditions of the Crimea is established. This conclusion is made on the basis of results of the analysis of mechanical structure and physical and chemical and biochemical properties of grapes and a mash and wine materials. According to a complex assessment of red grapes clones in the system "grapes - mash - wine-material" the differentiation of them on 3 groups characterizing the grapes potential is carried out. The grapes criteria indicators allowing to pick up the perspective technology of wine materials production are revealed. For the grapes clones of 1 group the classical technology is recommended, for the clones of 2 groups - of carbon pulp dioxide maceration, for clones of 3 groups the carbon dioxide grapes maceration is recommended. The received results give the chance further to recommend the technology of processing for receiving of qualitative wine when the introduced clones grapes are studied on mechanical structure and physical and chemical indicators on the harvesting stages.
