Phenolic potential of new red hybrid grape varieties to produce quality wines and identification by the malvin

The hybrids are new varieties that resistant to the cryptogamic diseases of vines, and they may be a good solution reduction pesticide use. However, these have appeared recently only few studies been conducted check quality wine produce. In this study, wines originated from were chemically characterized (polyphenols, tannins, anthocyanins, color analysis). Results show their oenological parameters close those Vitis vinifera wines. made Vinifera (100%), with Vidoc, all Bouquets studied malvidin-3 glucoside dominant, others cyanidin dominant. Furthermore, hybrid had higher concentration in condensed tannins lower one molecular compared wines, except for Vidoc As far as anthocyanin content is concerned, samples contained diglucosides, malvidin-3,5-diglucoside (malvin) most abundant one. Also, anthocyanins than normal do not contain any malvin. For other malvin co-eluted cyanidin-3- O -glucoside case, cyanidin’s was impressively current OIV method gives different results malvidol diglucoside use an HPLC chromatography (HPLC-DAD-QQQ). does appear reliable comparison detecting Finally, darker blue/purplish
