Disease Resistant Bouquet Vine Varieties: Assessment of the Phenolic, Aromatic, and Sensory Potential of Their Wines.

ABSTRACT: The search for grape varieties resistant to diseases and to climatic changes notably concerns the wine industry. Nine monovarietal wines from new red grape varieties resistant to cryptogamic diseases (downy and powdery mildews) were evaluated in terms of their total phenolic, anthocyanin and proanthocyanidin contents, anthocyanin profile, volatile composition, and sensory attributes. Thus, the question remains, will these hybrid grapes (≥97.5% of Vitisvinifera genome) lead to wines with organoleptic properties similar to those of Vitisvinifera wines that consumers are used to? Total phenolic (1547-3418 mg GA/L), anthocyanin (186-561 mg malvidin/L), and proanthocyanidin (1.4-4.5 g tannins/L) contents were in broad agreement with those previously described in the literature for monovarietal
