The article presents the results of studying the enocarpological characteristics of bunches and berries of local and introduced table and wine grape varieties cultivated in the Absheron region. In the course of the studies, it was found that indicators such as bunch weight, stem weight, skin and pulp residue, juice yield, and the amount of solid residue varied over a wide range depending on the grape variety; in particular, large, medium and small bunches were observed. During the research, it was found that such table and technical grape varieties as Tuya-tish, wild form 2, Alphonse Lavallee, Nagshebi, Digah kechimemesi, Gyozel uzum, Ganjavi, Digah gorasy, Ag Kharji, Uzun salkhym, according to enocarpological indicators (bunch weight, stem weight, skin and pulp residue, juice yield, percentage of seeds in the berry, weight of 100 seeds, solid residue) were noticeably different from other varieties. In the studied table grape varieties, the enocarpological parameters varied over wide ranges, the average weight of the bunch was 210.0-974.0 g, the weight of the stem concerning the total weight of the bunch was 0.7-9.6%, the residue of the skin and pulp was 18.0-40.0 %, juice yield 51.0-72.7 %, seeds 2.4-10.8 %, amount of solid residue 27.3-49 %, and weight of 100 seeds 2.7-14.0 g. In wine grape varieties, these indicators differed from table varieties. They were estimated as follows: bunch weight 178.7-548.0 g, stem weight concerning the total weight of the bunch 1.8-6.5 %, the skin and pulp residue 14.7-31.6 %, juice yield 64.1-76.2 %, seeds 2.7-7.4 %, amount of solid residue 23.8-43.0 %. The highest weight of the bunch, stem, remaining skin and pulp, number of seeds, weight of 100 seeds, and the lowest juice yield were noted in table varieties; for wine grape varieties, this ratio was the opposite.
