Balsamic refers to a type of vinegar originating from Italy, particularly the region of Modena. It is made from freshly crushed grape must, which is cooked down and then aged in wooden barrels. The aging process can last from several years to decades, resulting in a rich, complex flavor that is both sweet and tangy. There are different types of balsamic vinegar, including Traditional Balsamic Vinegar of Modena, which is highly regulated and has a protected designation of origin. Another common type is Balsamic Vinegar of Modena IGP, which is more widely available and often blended with wine vinegar. Both types are popular in salad dressings, marinades, and drizzled over various dishes.
