Wine vinegar is a type of vinegar made from fermented wine. The process involves converting the alcohol in wine into acetic acid through the action of bacteria. This gives wine vinegar its distinct tangy flavor, which can vary depending on the type of wine used, such as red or white. Commonly used in cooking and salad dressings, wine vinegar adds acidity and depth to dishes. It can also be used as a marinade or a preservative. Additionally, wine vinegar is often praised for its potential health benefits, including aiding digestion and providing antioxidants.
