Story summary
  • Sourdough bread made with traditional ingredients is not gluten-free because it uses wheat, rye, or barley.
  • Only sourdough made with certified gluten-free grains, such as quinoa or millet, is truly gluten-free if there is no cross-contamination.
  • Fermentation can make sourdough easier to digest, but it does not eliminate gluten.
  • For people with celiac disease or gluten sensitivity, gluten-free sourdough is an option when made with appropriate ingredients.
