In this study, SV 18402 interspecific hybrid (PIWI group grapevines) was subjected to processing by syruping the berries before boiling. The variants were: V1.1. - grape product from berries without skin – filtered; V1.2. - grape product from berries without skin – unfiltered; V2.1. - grape product from berries with skin– filtered; V2.2. - grape product from berries with skin – unfiltered. Before processing, raw material was assessed for total soluble solids (186 g/l sugar), pH (3.25), and acidity (7.35 g/l tartric acid). The variants of products measure soluble dry substance over 67% the minimum amount stipulated by the international standard, which guarantees the conservability of the product. Regarding sensory comparison, products from the whole berries (skin, pulp, and seeds) proved to be more acceptable by the general public, as compared to the other variants.
