During fermentation a lot of the sugar is converted to acid. But there is still more sugar than regular vinegar has. So real aged balsamic vinegar has more calories from the grape sugars.
The vinegar is cooked in pressurized vats and aged for at least two months in large wooden barrels. There is no fermentation stage. Balsamic Vinegar of Modena I.G.P. must contain wine vinegar to bring its acidity to at least 6%, and can contain up to 50% wine vinegar, often both aged and young. It may contain thickening agents, caramel, or other colorants to make it more like real balsamic.
