Masserie di Sant'Eramo Balsamic Vinegar of Modena is made from red grape must which is first concentrated in open vats over a wood fire, then slowly fermented and mellowed in progressively smaller oak casks. This centuries-old method creates a vinegar with a palate pleasing balance between sourness and naturally sweet undertones. Modena Masserie di Sant’Eramo’s intense aroma and rich flavor make it an exceptional choice for salad dressings, vinaigrettes, marinades and all recipes that call for the finest vinegar. Acidity 6%. Each bottle contains 17 fluid ounces. From Modena, Italy.
