Wines with longer skin maceration times promoted a greater extraction of phenolic compounds from the skins and had, at the moment of bottling, higher color density. After one year of storage, the wines elaborated with 10 days of skin maceration had higher color density, anthocyanin content, and polymeric compound content, whereas wines elaborated with 4 days of maceration had higher tint and lower content of phenolic compounds. The data were evaluated using principal component analysis. The effects of the maceration length and storage time were clearly reflected in this analysis. ER -
