Red wine vinegar is a type of vinegar made from fermented red wine. The fermentation process involves converting the alcohol in the wine into acetic acid, which gives the vinegar its characteristic tangy flavor. It is commonly used in salad dressings, marinades, and sauces, adding depth and acidity to various dishes. This vinegar is rich in antioxidants and can enhance the taste of foods while providing potential health benefits. Red wine vinegar is often preferred for its robust flavor compared to other types of vinegar, making it a popular choice in Mediterranean cuisine and beyond.
