Balsamic vinegar is a dark, flavorful vinegar originating from Modena, Italy. It is made from freshly crushed grape juice, which is cooked down to create a concentrated syrup called must. This syrup is then aged in wooden barrels for several years, developing its rich taste and complex aroma. There are two main types of balsamic vinegar: traditional and commercial. Traditional balsamic vinegar is aged for a minimum of 12 years and has a thick, syrupy consistency, while commercial varieties are often produced more quickly and may contain added ingredients. Both types are popular in salad dressings, marinades, and drizzled over dishes.
