Choosing the best balsamic vinegar is easy if you know what to look for. The first thing is aging. To be a traditional balsamic vinegar, it has to be aged at least 12 years. The ingredients are also important. It should include grapes while the cheaper ones will have wine vinegar, flavorings, and other ingredients. Also, where it is made is another good indicator. It should be made in the Reggio or Modena areas.
