All natural. The origin of Terra Medi White Vinegar is the flavorful Corinthian grape, grown on the verdant estates of Greece's Peloponnese. The must is naturally extracted from the grapes and fermented, producing this pure, crisp vinegar. The vinegar's golden hue is derived from natural pigments in the grape skins, with no additional colors or sweeteners. It is a perfect companion to our extra virgin olive oil. Naturally - Occuring grape sediment may be present. Acidity (6%). www.Terramedi.com. Product of Greece.
