Question: is malt barley vinegar gluten free?
Answer: Gluten is removed during the distillation process rendering the final product gluten-free. Malt vinegar, which is usually made from barley but may also be made from rye and called rye vinegar, is not gluten-free. Malt or rye vinegar is not safe for those with celiac disease. It is not distilled and contains gluten.
