<<Disclaimer: Verify this information before applying it to your situation.>> Hi All... Wanted to report that I called Manwich this morning and they say that their products are gluten free... BUT the vinegar they use may be processed with either corn or wheat. So, I guess whether or not you use the product depends on where you stand on the distilled vinegar controversy. Personally, I have read enough scientific evidence to believe that gluten does not survive the distillation process and therefore products which contain distilled vinegar are safe for celiacs.
