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.
