Since 1850 the Malpighi family has kept more than 3,500 barrels of PDO Traditional Balsamic Vinegar of Modena in its vinegar loft on Via Vignolese, now flanked by the Taste&Tour museum with documents, antique tools and centuries-old barrels. Guided tours, free by appointment, last from half an hour to ninety minutes and end with a vertical tasting, from the youngest vinegar to the oldest.
