You don't have to spend a fortune, but do avoid those with caramel colouring and added flavourings. A good quality balsamic vinegar will make a difference in all your recipes! If you're looking for a good everyday balsamic vinegar, the Kirkland brand sold at Costco gets great reviews. Any balsamic vinegar you buy should bear a "di Modena" label. This label indicates that it was produced near Modena in the Reggio Emilia province of Italy. Traditional balsamic vinegar is always labelled Aceto Balsamico Tradizionale. It carries a special D.O.P. stamp certifying its place of origin, production and quality. Its only ingredient is grape must.
