Detalhes bibliográficos
Resumo:The Brazilian wine industry has a remarkable characteristic that distinguishes from other markets. While the foreign market only accepts products originating from European cultivars (cv) (Vitis vinifera), in Brazil, products originating from American cv (Vitis labrusca and Vitis bourquina) and hybrids are also accepted. Dry and sweet varietal wines from red grapes cv Bordô, Isabel and Máximo and white grapes cv Niágara and Lorena were analyzed, by the following chemical standard analyses: total, volatile and fixed acidity; ethanol content; density; pH; dry and reduced dry extract; ratio ethanol/reduced dry extract; reducing sugars; total and free sulfur dioxide. Additionally, major volatile compounds were analyzed by gas chromatography, directly, without any previous treatment, after the addition of the internal standard (4-nonanol).
