The valorization of viticulture by-products (e.g., grapevine pomace and canes) in the nutraceutical industry represents a paradigm shift in sustainable resource management and innovation. Thus, recognizing the untapped potential within these residues, the nutraceutical industry has embraced them as valuable but less exploited raw materials. These wastes are characterized by a high polyphenolic composition with antimicrobial, antioxidant, anti-inflammatory, and cardioprotective effects, especially resveratrol, gallic acid, and proanthocyanidins. Therefore, this mini-review aims to update the potential of viticulture wastes for the production of polyphenol-rich nutraceuticals and nanoparticles used as bioactive molecule carriers. Additionally, the modulator effect of grape pomace on human and animal microbiota was highlighted. The viticulture waste valorization aligns with the principles of the circular economy while creating new revenue streams for wineries.
