Easy Gluten-Free Sourdough Starter
Equipment
- Clean glass or ceramic bowl
- Paper plate or cloth for covering
- Wide-mouthed jar with tight-fitting lid
- Spoon for stirring and transferring
- Kitchen scale (optional but recommended)
Ingredients
Base Ingredients
- 290 grams Wholegrain flour Choose one or mix: sorghum, buckwheat, brown rice, amaranth, teff, millet, or quinoa
- as needed variable Water Filtered or dechlorinated works best
Instructions
- Day 1: In a clean glass or ceramic bowl, combine 50 grams of your chosen wholegrain flour with 60 grams of water. Stir everything together until you’ve got a thick pancake batter consistency—if it feels too stiff, just add another 10 grams of water to loosen it up.
- Loosely cover the bowl with something breathable like a paper plate or cloth. Leave it sitting on your counter at room temperature for a full 24 hours. This is where the magic begins: you’re inviting wild yeast and beneficial bacteria to join the party.
- Day 2: Stir down what’s in your bowl, then add 30 grams of wholegrain flour and 40 grams of water. Mix it all together and you’ll notice the starter’s beginning to smell slightly tangy—that’s exactly what we want.
- Cover loosely again and let it rest for 24 hours on the counter. You might not see tons of bubbles yet, and that’s totally normal. Patience is part of the gluten-free sourdough starter magic.
- Days 3 & 4: Repeat Day 2’s feeding for both days: add 30 grams of flour and 40 grams of water each morning (or whenever you remember—it doesn’t have to be exact). Stir, cover loosely, and leave for 24 hours each time.
- By now, your gluten-free sourdough starter should start smelling noticeably sour and funky. You might see some bubbles forming on the surface—these are signs your starter’s waking up and getting stronger.
- Day 5: Remove the loose cover and discard roughly half of your starter into the sink (no need to measure precisely). Feed what remains with 30 grams of wholegrain flour and 40 grams of water, just like before.
- Loosely cover and let it sit for another 24 hours. Discarding might feel wasteful at first, but it keeps your starter healthy and prevents it from becoming too acidic or developing an unpleasant smell.
- Day 6: Remove the cover and feed with 30 grams of flour and 40 grams of water—but this time, do not discard anything. Cover loosely and leave for 24 hours.
- This feeding schedule helps your gluten-free sourdough starter build strength without the yeast and bacteria getting too concentrated. You’re balancing growth with stability.
- Day 7: Remove the cover, discard roughly half your starter again, then feed with 30 grams of flour and 40 grams of water. Cover loosely and leave for 24 hours.
- This pattern of alternating discard and non-discard feedings is key to maintaining a healthy, active gluten-free sourdough starter with excellent rising power.
- Day 8: Feed with 30 grams of flour and 40 grams of water—no discard this time. Cover loosely and leave for 24 hours.
- You should be seeing more consistent bubbling by now, and the aroma should be pleasantly sour and slightly alcoholic-smelling. This is your gluten-free sourdough starter telling you it’s ready to work harder.
- Day 9: Remove the cover, discard roughly half, and feed with 30 grams of flour and 40 grams of water. Cover loosely and leave for 24 hours.
- Your starter’s almost there! The bubbles should be more abundant, and the texture should look lighter and fluffier than it did on Day 1.
- Day 10: Remove the cover and take a good look—your gluten-free sourdough starter should be very bubbly with a pleasantly sour aroma (you know, the good kind that makes you excited to bake).
- Spoon your active starter into a wide-mouthed jar with a tight-fitting lid and move it to the refrigerator. Congratulations—you’ve successfully created a gluten-free sourdough starter that’s ready for baking adventures!

By now, your gluten-free sourdough starter should start smelling noticeably sour and funky. You might see some bubbles forming on the surface—these are signs your starter’s waking up and getting stronger.
Day 5: Your First Discard
Here’s where things shift: remove the loose cover and discard roughly half of your starter into the sink (no need to measure precisely). Feed what remains with 30 grams of wholegrain flour and 40 grams of water, just like before.
Loosely cover and let it sit for another 24 hours. Discarding might feel wasteful at first, but it keeps your starter healthy and prevents it from becoming too acidic or developing an unpleasant smell.
Day 6: Feed Without Discarding
Remove the cover and feed with 30 grams of flour and 40 grams of water—but this time, do not discard anything. Cover loosely and leave for 24 hours.
This feeding schedule helps your gluten-free sourdough starter build strength without the yeast and bacteria getting too concentrated. You’re balancing growth with stability.
Day 7: Back to Discarding
Remove the cover, discard roughly half your starter again, then feed with 30 grams of flour and 40 grams of water. Cover loosely and leave for 24 hours.
This pattern of alternating discard and non-discard feedings is key to maintaining a healthy, active gluten-free sourdough starter with excellent rising power.
Day 8: Another Feed Without Discard

Substitutions & Flour Variations
Sorghum flour is my go-to for gluten-free sourdough starter because it develops tang quickly and has a mild flavor that won’t overpower your finished bread. It’s reliable, forgiving, and produces consistently good results.
Buckwheat flour creates a nuttier, earthier gluten-free sourdough starter with a slightly faster fermentation timeline. Fair warning: it can smell a bit stronger during development, but that’s totally normal and doesn’t affect the final product.
Brown rice flour gives you a more delicate, subtle flavor in your gluten-free sourdough starter and works beautifully when mixed with other grains. It ferments a bit more slowly, so you might need an extra day or two to see the same level of activity.
Amaranth, teff, millet, or quinoa each bring unique characteristics to a gluten-free sourdough starter. I’d recommend trying these once you’re comfortable with the basic process—they’re more adventurous but equally rewarding.
Troubleshooting Tips
My starter isn’t showing bubbles by Day 10. Don’t panic! Some gluten-free sourdough starter varieties take longer to establish. If you’re using brown rice flour or a blend, consider feeding it a few more times (once daily for 3–5 days). The wild yeast population is building even if you don’t see obvious bubbles yet.
There’s a dark liquid on top of my gluten-free sourdough starter. That’s hooch—a mixture of alcohol and water that forms when your starter gets hungry. You can stir it back in or pour it off; either way is fine. It just means your starter’s ready for its next feeding.
My starter smells like nail polish remover or rotting fruit. That’s typically a sign something went wrong—usually contamination or an overly acidic environment. Start fresh with new, clean equipment and filtered water. Make sure you’re discarding and feeding on schedule to keep your gluten-free sourdough starter balanced.
The starter looks moldy or has a pink/orange tint. This signals contamination and unfortunately means you should start over. Use fresh, sterilized equipment and make sure your gluten-free sourdough starter stays in a clean, undisturbed spot on your counter.
Storage & Meal Prep
Once your gluten-free sourdough starter reaches Day 10, transfer it to a clean, wide-mouthed jar with a tight-fitting lid and refrigerate it. It’ll stay healthy for weeks (even months) in cold storage, waking up beautifully each time you feed and use it.
For regular baking: Feed your starter about 8–12 hours before you plan to bake, let it come to room temperature, and use it once it’s bubbly and active. Between bakes, store it in the fridge and feed once a week to keep your gluten-free sourdough starter happy and ready.
For long-term storage: If you won’t be baking for a few weeks, feed your starter once, let it settle for a day at room temperature, then refrigerate it. It’ll be dormant but perfectly fine—just feed it a few times before baking to reactivate the yeast and bacteria.
Serving Suggestions & Pairings
Your gluten-free sourdough starter is the foundation for tangy, chewy bread that pairs beautifully with everything from morning avocado toast to evening soups and stews. The wild yeast fermentation creates a complex flavor that makes even simple meals feel special.
Think crusty gluten-free sourdough bread torn warm from the oven, slathered with good butter, or toasted with a drizzle of olive oil and sea salt. The possibilities are endless once your starter’s thriving and ready to work its magic.
Variations & Dietary Adjustments
All-gluten-free flour blends: If you prefer commercial blends over single-grain flours, they work wonderfully for a gluten-free sourdough starter—just make sure they don’t contain xanthan gum (it can interfere with wild yeast activity). Pick one blend and stick with it through all 10 days for consistency.
Mixed-grain approach: Well, you can absolutely blend two or three wholegrain flours together for your gluten-free sourdough starter—it often produces more complex flavor and faster fermentation. Try equal parts sorghum and buckwheat, or amaranth and brown rice, for interesting variations.
Maintaining in cooler climates: If your kitchen stays on the chilly side, give your gluten-free sourdough starter an extra 6–12 hours at each stage. Cold temperatures slow down wild yeast activity, so patience becomes your best friend—the results are absolutely worth the wait.
Gluten-Free Sourdough Starter FAQs
Is gluten-free sourdough starter possible?
Absolutely! Wild yeast and bacteria thrive on any wholegrain flour, not just wheat. Your gluten-free sourdough starter will develop just as robustly as traditional versions—sometimes even faster, depending on the flour you choose.
Can sourdough ever be gluten-free?
Yes, completely. Once you’ve got an active gluten-free sourdough starter, you can use it to make bread with any gluten-free flour blend or wholegrain flour combination. The fermentation process is what creates that iconic sourdough tang and texture, not the wheat.
What are common problems with gluten-free sourdough?
The biggest issues are patience (it can take longer to rise) and water ratios (gluten-free flours absorb liquid differently). Your gluten-free sourdough starter itself is usually the easy part—the learning curve comes when you’re baking the actual bread.
What is the best starter for gluten-free bread?
There’s no single “best” choice—it depends on your taste preferences and what you have on hand. That said, sorghum creates a reliable, predictable gluten-free sourdough starter for beginners, while buckwheat brings more personality to the flavor profile.
How to feed a gluten-free sourdough starter?
Add 30 grams of wholegrain flour and 40 grams of water to your starter, stir, and cover loosely. Follow the discard-and-feed pattern outlined in the 10-day guide to keep your gluten-free sourdough starter strong and ready for baking.
What is the biggest mistake you can make with your sourdough starter?
Skipping the discard feedings. You might think you’re saving flour, but discarding actually keeps your gluten-free sourdough starter healthy, prevents overly strong acidity, and ensures consistent rising power when you bake. Trust the process!
Final Thoughts
Creating a gluten-free sourdough starter from scratch is one of those kitchen projects that feels way more complicated than it actually is. Man, oh man, the sense of accomplishment when you pull that bubbling, fragrant starter out of the fridge for the first time? Totally worth every bit of attention you gave it over those 10 days.
