Quick Answer:
Most mustards are gluten-free, but it depends on the brand and ingredients. Mustard seeds are naturally gluten-free, but added ingredients, especially vinegar and flavorings, can contain gluten. Always read the label and look for a gluten-free certification to be safe.

While the seeds themselves are gluten-free, issues may arise with the added ingredients.
- Malt vinegar (made from barley and contains gluten)
- Flavorings or thickeners.
- Cross-contact during processing.
How to Tell if Mustard is Gluten-Free:
Here’s what to watch for on the label:
- Avoid malt vinegar because it is made from barley.
- Natural flavors can come from gluten sources.
Even trace amounts of gluten (from shared equipment) can be a problem for sensitive individuals. A gluten-free label ensures the product has been tested and contains less than 20 ppm of gluten.
If you’re not highly sensitive, you could choose mustard without certification as long as no gluten-containing ingredients are listed.

Thank you for the education. I had no idea that some mustards weren’t gluten free. I assumed they were all fine. Instead of just a gluten free list, can you please add a list of mustards that have gluten?
I am glad it is helpful. It is hard to keep a full listing because many brands are regional, but I will try to add more.
