Balsamic Vinegar of Modena PGI is not only one of the most exported and well-known Italian products in the world; it is also part of the European heritage of Geographical Indications. In fact, since 1994, the European Union has established a legal system for the recognition and protection of Protected Designations of Origin (PDO) and Protected Geographical Indications (PGI), creating the first list of products with a geographical indication at the EU level. 

Aceto Balsamico di Modena, despite its millennial history, obtained the prestigious recognition of PGI only in 2009. What lays behind this acronym and the yellow and blue logo that stands out on the labels of Aceto Balsamico di Modena?
