The Full Answer

Plain yellow mustard is typically gluten-free. Mustard seeds, vinegar, water, and turmeric — the main ingredients — contain no gluten. French's Yellow Mustard and most store-brand yellow mustards are safe.

However, some mustard varieties carry gluten risks. Traditional Dijon mustard is made with verjuice or wine (safe), but some brands use wheat flour as a thickener. Beer mustard obviously contains barley. Some "honey mustard" dressings may contain wheat-based thickeners.

Always check the ingredient list, especially on Dijon, whole grain, and specialty mustards. Maille and Grey Poupon Dijon are generally considered safe, but verify the specific variety.
