Flavonols are important compounds in terms of wine quality,
since they contribute to the bitterness and colour of the wine,
stabilizing the anthocyanins. The values for some of the flavonol
compounds, such as myricetin, quercetin and kaempferol, were
higher in the Merlot samples, and the control samples for both
varieties showed higher contents than the wines produced with
dried grapes. Nevertheless, the total contents of flavonol compounds
observed in this study for the wines produced with dehydrated
grapes were higher than those reported by Marquez et al.
(2012).
