What Is A Sourdough Starter?
A sourdough starter is a fermented mixture of flour and water filled with natural wild yeast and beneficial bacteria. Over time, the microorganisms develop naturally and create the rise, texture, and signature tangy flavor sourdough is known for.
Instead of commercial yeast, sourdough baking relies on this active starter to help bread and baked goods rise naturally.
Supplies You’ll Need
Glass Jar
A quart-sized glass jar works best. Avoid metal containers whenever possible.
Lid Or Cover
A loose lid, paper towel, or cloth secured with a rubber band allows airflow while protecting the starter.
Wooden Spoon
Many bakers prefer using wood or silicone instead of metal utensils.
Ingredients & Why They Matter
Flour
Unbleached all-purpose flour and whole wheat flour work beautifully for beginners. You can also experiment with:
- Bread flour
- Rye flour
- Einkorn flour
- Whole wheat flour
Whole grain flours often help starters activate more quickly because they contain more natural yeast.
Water
Filtered or purified water is ideal. Chlorinated tap water may slow or damage the natural fermentation process.
If using tap water:
- Let it sit uncovered for 24 hours before using
OR - Use bottled water
How To Make A Sourdough Starter
The process is surprisingly simple. The key is consistency and patience.
Basic Measurements To Remember
- ½ cup flour
- ¼ to ⅓ cup water
These same measurements are used repeatedly during the feeding process.
Day-By-Day Sourdough Starter Guide
Day 1 — Start The Starter
- Add:
- ½ cup flour
- ¼ cup water
- Stir until a thick pancake-batter consistency forms.
- Cover loosely with a paper towel or lid.
- Let sit at room temperature for 24 hours in a warm spot.
Ideal temperature: about 70°F.
Day 2 — First Feeding
After 24 hours:
- Check for bubbles
If bubbles appear:
- Add:
- ½ cup flour
- ¼ to ⅓ cup water
- Stir thoroughly.
- Rest another 24 hours.
If no bubbles appear:
- Stir once and wait another day. This is completely normal.
Day 3 — Second Feeding
- Remove half of the starter.
- Add:
- ½ cup flour
- ¼ to ⅓ cup water
- Stir well and let rest 24 hours.
At this point, you should begin noticing more activity and a slightly tangy aroma.
Days 4–6 — Continue Feedings
Continue removing half and feeding once or twice daily.
Your starter is ready when:
- It consistently bubbles
- Doubles in size within 6–8 hours after feeding
- Smells pleasantly tangy and yeasty
How To Know Your Starter Is Ready
A mature starter should:
- Be bubbly throughout
- Rise predictably after feeding
- Smell pleasantly sour, not rotten
- Pass the “float test” (a spoonful floats in water)
Once active, it’s ready for baking!
How To Store A Sourdough Starter
Refrigerator Storage
Once active, store the starter in the refrigerator with a loose lid.
Feed it:
- About once per week
Before baking:
- Remove from refrigerator
- Feed the starter
- Let it sit at room temperature for 12–24 hours until bubbly and active again
Signs Your Starter Has Gone Bad
Healthy sourdough starters smell tangy and fermented.
Throw it away if you notice:
- Pink or orange color
- Mold
- Rotten or foul smell
- Fuzzy growth
Don’t worry—starting over is easy!
What To Do With Sourdough Discard
The “discard” is the portion removed before feeding your starter. Don’t throw it away! It can be used in so many delicious recipes.
Delicious Sourdough Discard Ideas
- Pancakes
- Pretzels
- Crackers
- Brownies
- Cinnamon rolls
- English muffins
- Banana bread
- Chocolate chip cookies
- Pasta dough
The discard adds incredible flavor even before the starter becomes fully mature.
