Frequently Asked Questions

Can all sourdough bread be considered gluten-free?

No, traditional sourdough bread is not gluten-free as it’s made with wheat flour which contains gluten. While the fermentation process may reduce gluten content slightly, it’s still unsafe for those with celiac disease or gluten sensitivity.

How do I know if the sourdough starter was made with gluten-free flour?

Ask the person who made it or check the original flour packaging used to create the starter. If you’re buying a commercial starter, it should be clearly labeled as gluten-free.

If traditional sourdough breaks down some gluten, is that enough for someone with celiac to tolerate it?

No, traditional sourdough bread is still unsafe for people with celiac disease as it contains too much gluten even after fermentation. Only gluten-free sourdough made with non-gluten grains is safe for celiac patients.

Are there any reliable brands of gluten-free sourdough bread available in regular grocery stores?

Canyon Bakehouse and Schar both make gluten-free sourdough bread that’s widely available in major grocery chains. Simple Kneads also offers a good gluten-free sourdough, though it’s found more commonly in specialty stores and natural food markets.

Does gluten-free sourdough bread have the same tangy flavor profile as traditional sourdough?

Gluten-free sourdough bread can develop a similar tangy flavor through fermentation, but it’s typically milder than traditional wheat sourdough. The flavor intensity depends largely on the specific gluten-free flours used and fermentation time.
