The article contains the results the study of the mechanical composition of clusters and biochemical characteristics of the red wine grape varieties of Cabernet Sauvignon, Cabernet Franc and Merlot (regionalized), Cabernet Carbon, Cabernet Kortis and Verdot black (introduced). In terms of the structure of the cluster of the variety they can be divided into three groups: Cabernet Kortis and Cabernet Sauvignon (16,6-16,8), Cabernet Carbon, Cabernet Franc and Verdot Black (17,5-17,9), Merlot (19.9 ). In terms of addition of the variety they can be divided into four groups: Cabernet Franc (6.3), Cabernet Sauvignon and Merlot (4.9-5.0), Cabernet Carbon (4.3), Verdot Black and Cabernet Kortis (3, 7-3,4). Structural parameters of the clusters of the varieties we have studied were ranged from 5.1 to 5.6, and the berry from 64.3 to 74. The yield of the wort from Cabernet Sauvignon, Cabernet Franc and Merlot is equal to 75,1-77,7% from Cabernet Carbon, Cabernet Kortis and Verdot Black - 70,5-72%. Mass concentration of sugars in the studied varieties was in the range of 22,3-26 g / 100 cm3, titrated acids - 0,47-0,77 g / 100 cm3, active acidity - 3.1-3.8. The ratio of fructose to glucose was: Verdot Black - 1.2, Cabernet Sauvignon and Cabernet Carbon - 1.5, Cabernet Kortis - 1.8, Kabernet Franc - 2.8, Merlot - 3.2. Most ranged organic acid in all varieties – wine acide. Relation of the content of tartaric and wine acids in varieties amounted: Cabernet Kortis 7: 1, Ca
bernet Karbon 6: 1, Cabernet Franc 2.8: 1, Cabernet Sauvignon and Merlot 2: 1, Verdot Black 1,4-1. Mass concentration of cations in the varieties was (in mg / dm3): potassium - 816,4-1770, sodium - 13,03-21,31, magnesium - 76,21-106, calcium - 52,24-89,45. In comparison with Cabernet Sauvignon larger potassium cations had Cabernet Franc and Merlot, sodium cations - Cabernet Carbon, Cabernet Franc, Merlot, magnesium cations - Cabernet Carbon, Kortis, Cabernet, Merlot, calcium cations - Cabernet Kortis, Merlot and Cabernet Carbon
