The article presents the characteristics of the mechanical composition of clusters, the chemical composition of grape juice and fresh grapes and wine tasting evaluation of three varieties of table. We have identified the following uvologic indicators of clusters of cultivars Flora, Nisina and Anyuta: structure - 90.0; 91.5; 87.3; addition - 8.0; 6.6; 10.8; structural - 6.4; 5.4; 8.1; berries - 17.6; 15.0; 10.4. In the studied berries of grape varieties the mass concentrations of sugars and titratable acids were in the range 18,1-23,5 and 0,73-0,78 g/100 cm3 respectively. The combination of sweetness and acidity causes high taste properties of grapes. In grape berries of Flora and Nizina the concentration of fructose was two times more than glucose. Differences in the content wine, malic, lemon and succinic acids in berries varieties of Flora and Nizina were insignificant. In the berries of Anyuta variety, the concentration of lemon and succinic acids was more, malic was less than other varieties. Most of the studied varieties of berries contain malic and wine acids. More of cations of potassium, sodium, calcium and magnesium then in other varieties and it contain less than Anyuta berries. The difference in the content of various cations in the berries of varieties of Flora and Nizina is negligible. Tasting score of fresh grape of Flora variety was 7.0, Nisina - 7.8 and Aniyta - 7.6 points

The article contains the results of the study of mechanical composition of grapes and biochemical characteristics of white wine grapes for the production of juice of direct extraction and blending. Thus, the yield of studied grapes ranged from 7.5 to 13.2 t / ha: highest yielding varieties and hybrids of Pervenets Magaracha and Tsitronnyy Magaracha, and the lowest - Chardonnay and Pinot blanc. At an average weight of clusters of varieties were divided into three groups - large clusters (230-243 g) in varieties Pervenets Magaracha and Tsitronnyy Magaracha, medium (181-184 g) - the varieties Chardonnay and Pinot blanc, small (112-116 g) - the varieties Bianca and Viorica. By weight of the 100 berries were divided into four groups - Bianca and Viorica (I), Pervenets Magaracha (II), Chardonnay (III), Pinot blanc and Tsitronnyy Magaracha (IV). Weight of 100 seeds from the largest varieties Pinot blanc and Bianca, and the lowest - in the varieties of Tsitronnyy Magaracha and Chardonnay. The solids content in the juices of these varieties ranged from 19.4 to 21.8%, which corresponded to branded products and higher of commodity varieties. Mass concentration of sugars ranged from 18.4 to 21.3 g / 100 cm3. Titratable acid content in the juice was varied from 0.65 to 0.78 g / 100 cm3. Sugar-acid ratio, defined as the ratio of concentration of sugars and titratable acids ranged from 23.6 to 30. The recommended values for this indicator were within 22-30. According to the results of the tasting, we rated "excellent" the juices from the varieties of Tsitronnyy Magaracha, Viorica (19 points) and Bianca (17 points); "good" marks were given to the juices from Pinot blanc, Chardonnay, Pervenets Magaracha: this means that we can get juices of excellent quality from the grape varieties under study with the title of ampelographic variety; in addition, the juice of the grape of varieties Chardonnay, Pinot blanc, Bianca, Pervenets Magaracha due to their potassium content will be functional to improve the cardiovascular system. On the basis of the tasting we have conducted mixing of the juices from the varieties of Viorica and citron Magaracha with other juice varieties 50:50 and 70:30. Sensory evaluation showed that blending juices from the varieties of Viorika and citron juice Tsitronnyy Magaracha other varieties improves product quality and 50:50 increases by one the total score, and 70:30 - two units. Blend of the varieties of Viorica and Tsitronnyy Magaracha does not increase the total score, but gives the product a special flavor and aroma. Hence, using the grape varieties under study we can produce varietal juices with the name of their ampelographic type and blended juices to extend the assortment
