The influence of the maceration treatments on the polyphenolic composition of red wines produced from Croatian autochthonous cultivar 'Plavac malil (Vitis vinifera L.) has been investigated. The results showed that in general different skin contact times influenced the content of anthocyanins, total phenols and vanillin index in young wines. Prolonged skin contact time significantly increased the content of low molecular weight proanthocyanidins and decreased the content of anthocyanins. Young wine produced with maceration at lower temperature demonstrated the lower content of anthocyanins and proanthocyanins.

Abstract
The influence of the maceration treatments on the polyphenolic composition of red wines produced from Croatian autochthonous cultivar 'Plavac malil (Vitis vinifera L.) has been investigated. The results showed that in general different skin contact times influenced the content of anthocyanins, total phenols and vanillin index in young wines. Prolonged skin contact time significantly increased the content of low molecular weight proanthocyanidins and decreased the content of anthocyanins. Young wine produced with maceration at lower temperature demonstrated the lower content of anthocyanins and proanthocyanins. No significant differences were observed between the levels of anthocyanins, total phenols and proanthocyanidins in wines aged for 14 months. Weaker colour intensity of 14-month-aged wines was detected in the wine made with prolonged skin maceration time in which the ratio of proanthocyanidins/anthocyanidins was the highest
