Is Vinegar Gluten-Free?
Pure distilled vinegar is gluten-free. The single word “vinegar” on a food label implies cider/apple vinegar and is gluten-free.
Flavored and seasoned vinegars may contain gluten, most typically in the form of malt, so ingredient lists should be carefully read. If wheat protein is in vinegar, the label will say so.
Malt vinegar is not gluten-free, as malt is derived from the gluten-containing grain barley.
