In the text of article it is noted that now in the Russian Federation there is a deficit of domestic wine materials for production of champagnes and sparkling wines. The research that carried out at "Magarach" Institute showed that for expansion of raw material base for production of sparkling wines it is possible to use the new grapes varieties with increase resistance to diseases and higher frost resistance. For definition of possibility of use of new grapes varieties for production of pink and red sparkling wines we studied the introduced red grapes varieties growing on the experimental plots. As control the Cabernet Sauvignon grapes was taken. The physical and chemical composition of grapes and a must is determined by the standard methods and methods of analysis accepted in wine-making. Data processing was carried out by means of mathematical statistics methods. The physical and chemical indicators of introduced from France and Italy grapes varieties (Malbek, Marselan, Sira, Barbera, Pti Verdo, Arinarnoa) are researched for definition of their possible use in the production of red sparkling wine materials and champagne. It is established that the studied varieties have a rather high capacity of phenolic substances. Mass concentration of sugars in a musts for the grapes growing in LLC "Legenda Kryma" is 180-215 g/dm3, titrable acids - 6,9-12,7 g/dm3, phenolic substances - 145-383 mg/dm3. The highest concentration of phenolic substances is defined in a must from Marselan grapes (383 mg/dm3) and Sira grapes (378 mg/dm3). It will allow to receive further from these grapes varieties the red wine materials with necessary contents of phenolic and color substances, regulating their accumulation by the different technological regimes.

The information on qualitative and quantitative cationic composition of wine materials for sparkling wines is very important as allows wine makers-technologists to pick up the schemes of necessary processings which carrying out guarantees stability of finished production and allows us to judge its safety. Under the conditions of the Republic of Crimea the influence on cationic composition of wine materials for pink and red sparkling wines of 2014 harvest of method of grapes processing and yeast race is studied. Determination of mass cations concentration of potassium, sodium, magnesium, calcium, copper, zinc and iron in the wine materials made from the studied grapes varieties which are grown up under the conditions of the Crimea has been carried out. It is established hat the cationic composition of wine materials for the sparkling wines produced from traditional, introduced and new grapes varieties of Magarach institute breeding, is typical for this kind of production. In the wine materials prepared on a red way, as a rule, more cations of sodium, potassium, magnesium and calcium are collected. It is shown that the accurate dependence of wine materials cationic composition from yeast race used for preparation hasn't been established. All studied wine materials are suitable for preparation of sparkling wines, and they are a valuable source of mineral substances for the consumer. The information on cationic composition of the studied wine materials is the addition to information on typicalness of mineral composition of wine materials for sparkling wines of the Crimea. The wine materials produced from specified grapes varieties are suitable for preparation of sparkling wines which are a valuable source of the mineral substances useful to a human organizm.
