Wine is directly fermented from 100% grapes or grape juice, which means that wine is 100% from grapes. Nutrients and health-care components in wine, especially phenols in wine grapes, are the material basis of health-care activities, and these active components are mainly distributed in peels and seeds. When eating grapes, most people don't eat them with seeds, and most people refuse because they are afraid of pesticide residues on the grape skin. So drinking wine is more nutritious than eating grapes directly.
