Red wine is a type of wine made from dark-colored grape varieties. The color comes from the grape skins, which are left in contact with the juice during fermentation. This process not only gives red wine its characteristic hue but also contributes to its flavor and tannins, which can create a rich and complex taste. There are many different types of red wine, including popular varieties like Cabernet Sauvignon, Merlot, and Pinot Noir. Each type has its own unique flavor profile, influenced by factors such as the grape variety, the region where it is grown, and the winemaking techniques used.
