With an acidity of 6% , our Organic Red Wine Vinegar is blended from the finest Italian red wines, Lambrusco and Trebbiano , both of which re made from the highest quality grape varieties grown in Italy. It’s then aged slowly for more than ten years in white Italian oak barrels , without added sulfites, producing a full-bodied vinegar with exceptional flavor. The wine is converted to vinegar using a slow, natural fermentation. The finished product is a premium, natural, barrel-aged vinegar with a robust flavor.
