Red Wine

Red wine is an alcoholic beverage made by fermenting the juice of dark-skinned grapes. Red wine is made with dark-skinned rather than light-skinned grapes. During red wine production, the winemaker allows pressed grape juice to macerate and ferment with the dark grape skins, which adds color, flavor and tannin to the wine. Alcohol occurs when yeast converts grape sugar into ethanol and carbon dioxide. The result of these processes: red wine.
