Summary: The Brazilian viticulture was consolidated in the mid-nineteenth century, with the
introduction of american grape cultivar Isabel (Vitis labrusca) by Italian immigrants,
replacing the vineyards of European grapes (Vitis vinifera). As one of the main raw
materials for the preparation of table wine in Brazil, cultivating Isabel is better adapted
to environmental conditions and a high production capacity and low susceptibility to
major fungal diseases that attack the vine. Wines made from grapes of the species
Vitis labrusca have the preference of many Brazilian consumers, so viticulture is
expanding throughout the country giving the characteristics of each region for the wine
made it. So the aim of this study is to characterize wines produced with Isabel grape
produced in different regions. In the first experiment were evaluated wines produced
in the north of the Espírito Santo state with Isabel cultivars, Bordô, and Blend (Isabel
+ Bordô). In the second experiment it was characterized wines produced with Isabel
cultivating four states (Espírito Santo, Minas Gerais, Rio Grande do Sul, Pernambuco),
and two seasons (2014 - 2015). The treatments of both experiments were composed
of three replicates each, and the variables analyzed were alcohol content (°GL), total
acidity and volatile (g.L-1
), dry extract (g.L-1
), SO2 free and total index color, tone
(420nm + 520nm), polyphenols, anthocyanins (mg.L-1
), phenolic compounds (mg.L-1
),
and organic acids. It was observed that the significant differences between the states,
and in the second experiment the state of Minas Gerais stood out. In the first
experiment to cultivate Bordô presented better values in relation to Isabel.
