Sažetak
The purpose of this investigation was to determine the characteristics of Cabernet Sauvignon/Kober 5BB berries according to the position of the rachis (bunch). The berries from 5 bunches (a total of 871 berries) were divided according to the position on the rachis (top, middle and bottom) and weight of berries (two classes of weight: 1) less than or equals 1g and 2) between 1.01 and 1.50 g). Each of the berries was used to evaluate physical characteristics (fresh berry weight, fresh weight of skin, seeds and flesh and seed number). Soluble solids content and total titratable acidity was measured on must obtained by crushing berries, taking into account the rachis position. Data analysis of berry percentage distribution showed that there was a difference between each weight category and position. From the top to the bottom rachis position, a decrease in percentage of berry number occurred. With regard to physical characteristics, the analysis of the results indicated a highly significant difference in berry weight between the measured classes and a significant difference between the positions. The analysis of skin, seed weight and seed number also indicated that there was a highly significant difference among the two classes of berry weight. Concerning the compositional parameters, the highest content of soluble solids and total titratable acidity were found in the bottom part of the bunch. Berry variability is a factor influencing the yield and quality of grape and wine. Generally, it is difficult to obtain a uniform size of berries under filed conditions.
