Red wine, a fermented beverage made from dark-colored grape varieties, serves as a versatile ingredient in both culinary and cocktail contexts. The fermentation process involves the grape skins, seeds, and stems, which impart the wine's rich color and complex flavors. Its broad range of flavor profiles, from fruity and floral to spicy and earthy, makes it an excellent choice for enhancing various dishes and drinks.

In the realm of cocktails, red wine is often used to add depth and sophistication. Sangria, a popular Spanish punch, incorporates red wine with fruit juices, soda water, and fresh fruits, creating a refreshing and aromatic drink. Additionally, certain cocktails, such as the New York Sour, combine red wine with spirits like whiskey to provide a layered taste experience, with the wine adding a balancing tartness and visual appeal when floated on top.
