| ABSTRACT It has been demonstrated that rootstocks can influence grape characteristics, but there are few data in literature about the rootstocks influence in the wine characteristics, especially in wines elaborated with Vitis labrusca or hybrid grapes. This study evaluated the influence of ‘IAC 766’ and ‘106-8 Mgt’ rootstocks on the physicochemical characteristics of ‘Bordô’, ‘Isabel’ and ‘IAC 138-22 ‘Máximo’ musts and wines. The musts were evaluated for pH, soluble solids, total acidity and soluble solids/acidity ratio. The wines were evaluated for density, alcohol content; total, volatile and fixed acidity; pH, dry extract, reducing sugars, reduced dry extract, alcohol in weight/reduced dry extract; free and total sulfur dioxide; anthocyanins,... |
