Guerzoni’s Aceto Balsamico Tradizionale di Modena extravecchio (Traditional Balsamic Vinegar of Modena extraold) is a superlative dressing, fruit of old traditionof the Estensedynasty, which obtained one of the most important alimentary certification: the D.O.P. mark (denomination of protectedorigin). It is produced by ageing cooked grape must, acetified in casks which are all strictly of different sizes and woods. The Traditional Balsamic Vinegar of Modena extraold benefits from a unique period of ageing, lasting more than 25 years.

Each year, as it ages, vinegar evaporatesout, further thickeningthe vinegar and concentrating the flavour, so each barrel is topped up with vinegar taken from the next barrel up.
