Description
Este trabalho centrou-se na caracterização sensorial e da composição volátil de vinhos brancos produzidos a partir de três castas minoritárias,
designadamente ‘Malvasia’ (Colares), ‘Verdelho’ e ‘Galego Dourado’. A caracterização ocorreu por meio de análise sensorial e por cromatografia
gás líquido de alta resolução, e os resultados obtidos foram analisados através de análise multivariada, que permitiu avaliar as semelhanças e as
diferenças entre as castas. Os resultados obtidos mostram uma diferenciação dos vinhos produzidos a partir de cada casta, mas acima de tudo uma
diferenciação das duas colheitas. Os resultados obtidos, tanto do ponto de vista sensorial como na composição química, mostram um potencial
enológico interessante destas castas, embora sejam necessários mais estudos para avaliar a influência dos efeitos climáticos no perfil de compostos
voláteis e também no perfil sensorial.
Abstract: This work focused on the characterization of the volatile compounds and sensory profile of white wines produced from three minority grapevine varieties of Portugal namely ‘Malvasia’ (Colares), ‘Verdelho’ and ‘Galego Dourado’. The characterization took place using sensory and gas chromatography analysis. Furthermore, the data obtained were analysed through the use of multivariate analysis, which made it possible to evaluate the similarities and dissimilarities between the varieties. The results obtained show a differentiation of the wines produced from each grapevine variety but above all a differentiation of the two vintages was verified. The results obtained, both from a sensory and a chemical point of view, show an interesting oenological potential of these varieties, but still require further studies, in order to evaluate the influence of climatic effects on the profile of volatile compounds and also on the sensory profile.
