Balsamic vinegar is a distinctive product with a rich history entrenched in the Italian regions of Modena and Reggio Emilia.

Traditional balsamic vinegar has origins dating back to the Middle Ages. Esteemed through time, it is more than a simple condiment; it’s a heritage, reflective of the region’s culture and time-honored traditions.

In Modena and Reggio Emilia, the cultivation and processing of grapes to create balsamic vinegar is a practice passed down through generations. This tradition involves the fermentation of the cooked grape must (the freshly crushed grape juice that contains the skins, seeds, and stems) and its progressive aging in a series of wooden barrels.

The term traditional balsamic vinegar denotes the strict adherence to time-tested methods. Your understanding of its value is heightened by knowing that Traditional Balsamic Vinegar (TBV) enjoys Protected Designation of Origin (PDO) status under European law. This status mandates a minimum aging period of 12 years and signifies the highest standards of production.
