Guerzoni’s Aceto Balsamico Tradizionale di Modena extravecchio (Traditional Balsamic Vinegar of Modena extraold) is a superlative dressing, fruit of old tradition of the Estense dynasty, which obtained one of the most important alimentary certification: the D.O.P. mark (denomination of protected origin). This Traditional Balsamic Vinegar of Modena extraold can be considered truly unique since, right from the beginning, the “Acetaia Guerzoni” vinegar loft has only ever used organic and biodynamic grapes.
