Phenolic and anthocyanin profile characterization of five disease resistant grape cultivars in septentrional context of France

Climate change has prompted the wine industry's growing interest in disease resistant interspecific hybrid wine grapes. Phenolic compounds, and specifically anthocyanins, play a powerful sensory and quality perception role in wine, but the anthocyanin profile of hybrid grapes can differ from those of traditional species Vitis vinifera L. To optimize winemaking strategies, there is a need for a better understanding of hybrid grape and wine composition. In this work, the phenolic compositions, anthocyanin profiles, and color parameters were evaluated and quantified for the five interspecific hybrid red wine grapes Vidoc, Coliris, Artaban, Chambourcin, and Divico (Vitis spp.) and their wines. These cultivars were assessed concurrently with Pinot noir, an emblematic septentrional V. vinifera cultivar known for its unique anthocyanin composition, sourced from multiple locations in Burgundy, France. This characterization sets the groundwork for further exploration of anthocyanin and phenolic interactions through wine color evolution in disease resistant wines.
