Viticultural by-products are known to contain high-value compounds such as stilbenes. Wine sector in Savoie Mont Blanc region (France) generates high amounts of waste including grape canes and grapevine stocks that remain unvalued. Herein, the potential of the most widespread grapevine varieties in Savoie Mont Blanc territory, Jacquère and Mondeuse, as sources of two stilbenes, trans-resveratrol (Rsv) and trans-ϵ-viniferin (Vf), was investigated for the first time. Using the reported extraction technique, the present work focused on several pre-extraction parameters influencing the extraction efficiency of these stilbenes from grape canes. The results indicated that various pre-extraction conditions significantly enhance the recovery of Rsv and Vf, ultimately contributing to a more sustainable utilization of viticultural by-products. This study provides foundational data that may lead to improved practices for extracting valuable compounds from viticultural waste in the Savoie Mont Blanc region.
