Abstract

The objective of this work was to evaluate the physicochemical composition of juices from the 'Bordô' and 'BRS Cora' grapes grown in an organic production system in the Serra do Sudeste region, in Southern Brazil, as well as to compare the cultivar results with data from other producing regions and with the requirements of the Brazilian regulation for whole grape juice. The used grapes came from a commercial vineyard, especifically from the 2016–2017, 2017–2018, and 2018–2019 production cycles. The juices were prepared by the steam drag method and evaluated for their physicochemical composition. The fruit showed suitable values for the parameters necessary for grape juice production. In general, the juices showed bioactive compounds contents similar to those obtained in other regions. The 'Bordô' juices evaluated in the three production cycles showed significant differences for several variables, which were attributed to the influence of weather on grape maturity. The juices of 'BRS Cora' showed high-consistency qualitative results even under the very distinct meteorological conditions of the three production cycles. The juices comply with the current Brazilian regulation for whole grape juice, except for soluble solids, which are severely lowered by the used extraction technique.Vitis labrusca; bioactive compounds; organic cultivation system; physicochemical composition.
