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 `Bordo', `Isabel' and `IAC 138-22 `Maximo' 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, polyphenols index (I 280); polyphenols and total flavonoids and antioxidant activity. The `Bordo', `Isabel' and IAC 13822 `Maximo' musts had low soluble solids for winemaking. The `106-8 Mgt' rootstock promoted higher dry extract content and reduced dry extract in Bordo wine, and lower total and fixed acidity in IAC 138-22 Maximo wine. In Isabel wine, higher pH was promoted by the `IAC 766' rootstock. Aside from low total acidity of the Bordo wine, all the physicochemical characteristics of the wines studied are in accordance with Brazilian law. There was no effect of rootstocks in the phenolics content and antioxidant activity of wines. Index terms: Vitis sp., table wine, classical analysis, phenolic compounds, antioxidant activity. (AU)
