Unlike, many European kinds of vinegar are derived from wine, balsamic is made with crushed skins, seeds, and stems called ‘grape must’, from ripe, white Trebbiano grapes, boiled into a concentrated grape juice. It is then processed by sequential fermentation (rincalzo in Italian) meaning, the juice is moved, annually from larger to smaller barrels made of different types of wood (i.e. oak, cherry, mulberry, ash, juniper, or chestnut) which affect the flavor and aroma. Balsamic, unlike its sister vinegars, takes the longest to ferment and age from ten to 25 years. The longer the fermentation, the more concentrated, richer in flavor, and more expensive. The term ‘aceto balsomico’ is unregulated, but there are three protected balsamic vinegars:
– Aceto Balsamico Tradizionale di Modena DOP (Traditional Balsamic Vinegar of Modena); made with reduced grapes
– Aceto Balsamico Tradizionale di Reggio Emilia DOP (Traditional Balsamic Vinegar of Reggio Emilia); made with reduced grapes
– Aceto Balsamico di Modena IGP (Balsamic Vinegar of Modena); made with grapes blended with wine vinegar and produced exclusively in either Modena or Reggio Emilia; less expensive and suggested for daily use
