Abstract: In the present study, the effect of pre-fermentative addition of three flavanol cofactors, including myricetin, kaempferol and quercetin, on the color and phenolic profile of ‘Cabernet Sauvignon’ dry red wine was examined during fermentation and aging. The results showed that the addition of flavanols before fermentation could effectively improve wine color density, enhance red tonality, and stabilize wine color during aging. Myricetin addition favored the extraction of polyphenols during fermentation to improve the stability of wine color during aging and showed better co-pigmentation effect than any other flavanol tested. This study provides scientific support for the application of flavanol cofactors in red wine production.

Key words: co-pigmentation; anthocyanins; flavanols; red wine; color
