Caracterização fenológica e potencial enológico da “Marselan” produzida na Campanha Gaúcha-RS

Abstract

The objective was to characterize the phenology and the evolution of the physicochemical composition of "Marselan" along ripening and some quality parameters in must and wine obtained from this cultivar. The experiment was conducted in a conventional espalier vineyard in Bagé, RS, in two cycles (2020/2021 and 2021/2022). The evaluations were made from budbreak to harvest, and the phenological stages and the thermal sum were evaluated. At maturity, soluble solids-SS, total acidity-TA (mEq.L-1) and pH were evaluated weekly in the must of 200 berries. The resulting wines had their physicochemical characterization determined through the WineScan™ SO2 equipment and the FOSS Integrator Version 1.6.0 software (FOSS, Denmark). Therefore, it is concluded that under the conditions in which the experiment was developed, the phenological data, the evolution of maturation and the physical-chemical characteristics of the must and wine obtained in the cycles 2020/2021 and 2021/2022 showed satisfactory results, proving that the cultivar 'Marselan' has the potential to be cultivated in Campanha Gaúcha. For the results of the analyses are in accordance with indices indicated in the literature and in the current Brazilian legislation.
