White Balsamic Vinegar is made from white wine vinegar made from Trebbiano grapes grown in the Modena area of Italy combined with concentrated, uncooked grape must.
White Balsamic vinegar has a mild slightly sweet flavor with a moderate amount of acidity about 5.2percent to about 7.0percent and lacks the abundant caramelized flavor of traditional Balsamic.
It works well in salad dressings and in any sauce where a red vinegar is undesirable. Don't confuse this with conventional Balsamic vinegar, which is dark red with a concentrated sweet flavor.
