Red wine stands apart from its white counterpart due to its use of dark-skinned grapes and unique production process. These grapes undergo maceration and fermentation, imparting color, tannins, and distinct flavors to the wine. Red wine's key characteristics include its diverse color spectrum, tannin content, wide-ranging flavors derived from grape varieties, and the crucial role of acidity in preserving and providing structure. Despite the vast array of red grape varieties worldwide, a few dominant ones dictate the red wine landscape, each offering its unique flavor profiles and origins.
