The ratio of stem fruit, skin, pulp, juice, and seeds is determined by mechanical analysis. A grapevine›s ratio between these components is crucial for winemaking, both in terms of yield and quality. This work aims to determine the mechanical composition of the local, less common varieties, Voskehat and Chilar. The weight of the bunch and berries, the number of berries in the bunch, as well as the weight of the seeds and the skin of the ridges are determined. The structure of the bunch, the composition of the berries, and the indicator of the composition of the bunch were calculated: For Chilar grape varieties, this indicator was higher at 1.8, while for Voskehat grape varieties, it was 1.4. Higher juice yields mean higher efficiency of wine production and lower wine costs for technical varieties.
