Modena is famous for its balsamic vinegar industry, which bears its name and stands as a symbol of quality.

The full name of the vinegar is: Aceto Balsamico Tradizionale di Modena (Traditional Balsamic Vinegar of Modena).

The preparation and aging process is long and lasts at least 12 years.

To allow visitors to the city to see how the vinegar ages, in 2003 the Modena balsamic vinegar consortium opened the Acetaia (vinegar aging cellar) in the attic of the Palazzo Comunale in Piazza Grande, where there are three sets of aging barrels.

With local explanations and guidance, it is possible to follow the preparation process that lasts many years.
