Ampelographic note

Il vitigno è caratterizzato dalla presenza di viticci trifidi, tetrafidi e pentafidi. altra peculiarità si manifesta con l'attaccamento di parte del rachide al germoglio. Presenta anche diverse foglie simmetriche. Spesso si incontrano foglie intere con appendici di lobi superiori od inferiori. Il lembo può essere a coppa o piano con margine leegermente contorto.

alcuni acini tendono leggermente all'ellittico.
