Vinegar adds tangy sweetness, and, depending on the source, various flavors to foods. It can be made by fermenting the natural sugars in almost any food, including fruit and fruit juices, wine and other alcohols, sugar syrups, and grains such as wheat or barley. Vinegar tastes somewhat like the food fermented to produce it. Distilled white vinegar, made from distilled alcohol, is nearly tasteless. If allergenic grains like wheat, rye or barley are the source of the fermentation, they will always be named in our ingredient statements.
