Red wine vinegar is a type of vinegar made by fermenting red wine. It has a rich, tangy flavour with a slight fruity undertone, which comes from the wine used in its production. The vinegar has a vibrant red to deep amber colour and is commonly used in Mediterranean cuisine, especially for salad dressings, marinades, and sauces. Its acidity and complex flavor profile add brightness and balance to dishes, and it works particularly well in vinaigrettes, braises, and reductions. Red wine vinegar can range in flavour from mild to sharp, depending on the aging process and the type of wine used.
