his is due, probably, to the increased oxidation recorded in test T1 because of the breaking of the berries with a bouquet which tends to enhance vegetable flavors rather than fruity. T1 wine also presents a tip of bitter significantly higher than T2 coming from the lignin of the stalks, to be exclusively attributed to the mode of transportation of the grapes, where the berries skins suffered significant lacerations compared to test T2.
