Monari Federzoni has been producing Balsamic vinegar products in Modena, Italy since 1912. Using an old world family recipe, Monari Federzoni has become the #1 brand of Balsamic Vinegar of Modena worldwide. Monari Federzoni combines traditional secrets of making Balsamic Vinegar of Modena with the most advanced technology. First, only the finest select grapes are used. Monari Federzoni has one of the largest vineyards in the Modena region where luscious Lambrusco, Trebbiano and Ancellotta grapes are grown in nutrient rich, fertile soil. The grapes are squeezed, creating a rich juice called "must." The must is then concentrated, blended with wine vinegar to begin fermentation, and matured in precious wooden casks.
