Originating in Italy, balsamic vinegar is a wine vinegar made from grapes that have been crushed, fermented and aged (Grape Must). Its sweet, pungent taste and mellow acidity make it a condiment for salad dressings and marinating. Balsamic vinegar is also nutritious, offering only 14 calories, no fat and trace amounts of several essential minerals per 1 tbsp. serving. Additionally, balsamic vinegar provides other healthful substances, including antioxidants, which protect cells in the body from oxidative damage associated with certain diseases.
