Learning how to make gluten free sourdough bread starter can feel overwhelming at first—especially if you’re new to gluten free baking. Traditional sourdough relies on wheat flour, but the good news is that you can create a delicious, bubbly, and active gluten free sourdough starter using simple gluten free flours and water.

What Is a Gluten Free Sourdough Starter?
A gluten free sourdough starter is a naturally fermented mixture of gluten free flour and water. Over time, wild yeast and beneficial bacteria develop, allowing the starter to rise bread without commercial yeast.
Even without gluten, fermentation still works beautifully when the right flours and feeding routine are used.

How to Make Gluten Free Sourdough Bread Starter (Day-by-Day Instructions)
Day 1: Create the Starter
In a glass jar, mix:
- ½ cup gluten free flour
- ½ cup water
Stir until smooth. Cover loosely and place in a warm area (70–80°F / 21–27°C).
Day 2: Check for Activity
You may see small bubbles or no activity yet—both are normal. Stir once and let rest.
Day 3: First Feeding
Discard half of the starter. Add:
- ½ cup gluten free flour
- ½ cup water
Mix well and cover loosely.
Days 4–6: Daily Feedings
Repeat the feeding process once daily. Bubbles will increase, and the starter will begin to rise slightly.
Day 7+: Starter Becomes Active
Your gluten free sourdough starter is ready when it:
- Bubbles consistently
- Develops a mild tangy aroma
- Shows slight rise after feeding
Understanding Gluten Free Starter Texture
Unlike wheat starters, gluten free starters are usually thinner and do not double dramatically. This is completely normal.
The ideal texture is similar to thick pancake batter.
How to Feed a Gluten Free Sourdough Starter
Room Temperature
- Feed once daily
- Discard half before feeding
- Use equal parts flour and water
Refrigerator Storage
- Feed once per week
- Bring to room temperature before baking
How to Store Gluten Free Sourdough Starter
- Short-term: Room temperature with daily feeding
- Long-term: Refrigerate with weekly feeding
- Label the jar with last feeding date
How to Use Gluten Free Sourdough Starter for Bread
Once active, your starter can be used for:
- Gluten free sourdough bread
- Flatbreads
- Pancakes and waffles
- Crackers
Most recipes use ½–1 cup active starter.
Common Problems and Troubleshooting
No Bubbles
- Room may be too cold
- Water may contain chlorine
- Switch to brown rice flour
Bad Smell
Sour is normal. Mold or rotten smell means discard and restart.
Too Runny
Add slightly more flour at the next feeding.
