This speciality from the Italian provinces of Modena and Reggio in the region of Emilia-Romagna is also known as balsamic vinegar, although it is actually not traditional vinegar and the production process has been completely different for centuries. Legend has it that the then most powerful Italian noble Duke Boniface of Canossa (985-1052) gave a bottle to the German Emperor Henry IV (1050-1106) on his proverbial journey to Canossa (30 km west of Modena). But this cannot be true, because the Canossa walk did not take place until 1077 and by that time Boniface had long since died
However, it is possible that Henry IV got to know the balsamic vinegar through Mathilde (1046-1115), the daughter and ruler-successor of Boniface. In any case, it is guaranteed that Lucrezia Borgia (1480-1519) ate a spoonful of balsamic vinegar every day as refreshment for body and soul. The Princes of Este first introduced a classification of "Aceto Balsamico" as early as the middle of the 16th century.
