How to Feed and Maintain a Sourdough Starter
As a passionate home baker, you know that a healthy sourdough starter is the foundation for creating tantalizing sourdough breads. In this comprehensive guide, we’ll teach you everything you need to know about feeding and maintaining your sourdough starter to ensure baking success.
The Power of Sourdough
A sourdough starter is a living, breathing entity that plays a pivotal role in the sourdough bread baking process. Unlike commercial yeast, a sourdough starter harnesses the power of wild yeast and beneficial bacteria to leaven your bread. This natural fermentation process not only produces a more flavorful and aromatic loaf, but it also enhances the texture and structure, giving your bread a delightful chewiness and improved shelf life.
Furthermore, the sourdough fermentation helps break down complex carbohydrates and gluten, making the bread easier to digest for those with gluten sensitivities. With its complex flavors, improved texture, and digestive benefits, a thriving sourdough starter is a true asset in the kitchen of any aspiring pastry chef.
Feeding Frequency
The frequency of feeding your sourdough starter depends on a few key factors, such as ambient temperature, desired fermentation speed, and your baking schedule. Here are some guidelines to help you determine the optimal feeding schedule:
- Daily Feeding: If you maintain your starter at room temperature (around 70-75°F) and want it to be ready for baking within a day or two, daily feedings are recommended. Discard a portion of the starter and feed it with fresh flour and water every 24 hours.
- Twice-Daily Feeding: In warmer environments or if you prefer a faster fermentation process, you can feed your starter twice a day, approximately every 12 hours. This helps keep your starter active and vigorous.
- Refrigerator Storage: If you don’t plan to bake frequently or want to slow down the fermentation process, you can store your starter in the refrigerator. When refrigerated, the feeding frequency can be reduced to once a week or even every two weeks. Remember to feed the starter and allow it to ferment at room temperature for a few hours before returning it to the fridge.
Experiment with different feeding ratios to find the one that works best for your baking needs. A common ratio is the 1:1:1 (starter:flour: water) or the 1:4:4 ratio, but feel free to adjust based on your observations and preferences.
Refreshing Your Starter
If your sourdough starter has been resting in the fridge for a while, it’s time to give it a refresh. Here’s how:
- Discard all but 25 grams of the starter.
- Add 100 grams of filtered water and 100 grams of flour.
- Mix vigorously with a spatula, cover lightly, and let it sit on the counter for a few hours to allow the yeast to multiply.
- Once the starter is active and bubbly, you can transfer it back to the fridge until the next time you need to bake.
FAQs for Sourdough starter
What is the best flour to feed my sourdough starter?
When feeding your sourdough starter, it’s best to use high-quality, unbleached organic flours such as all-purpose, bread, whole wheat, rye, or spelt. Each type of flour can contribute unique flavors and characteristics to your starter and final bread. Experiment to find the combination that suits your baking style.
What kind of water should I use in my sourdough starter?
It’s recommended to use filtered, spring, or dechlorinated tap water when feeding your sourdough starter. Chlorine and other chemicals can potentially hinder the activity of the natural yeasts and bacteria, so it’s essential to use water free from these impurities.
Can I use the discarded sourdough starter in recipes?
Absolutely! Don’t let that discarded sourdough go to waste. You can use it to make delicious pancakes, waffles, crackers, quick breads, and even pizza dough. The tangy flavor and moisture it adds will elevate your baked goods.
How do I make a backup of my sourdough starter?
To ensure you never lose your precious sourdough starter, it’s a good idea to create a backup. You can either dry it out and store the flakes or freeze it in ice cube trays. When you need to revive the backup, simply rehydrate it with water and flour, and you’ll have a fresh, active starter in no time.
Slow Fermentation or Lack of Activity
- Check the temperature: Ensure that your sourdough starter is kept in an environment with a consistent temperature between 70-75°F (21-24°C) for optimal fermentation.
- Adjust feeding schedule: Consider increasing the frequency of feedings to provide more food for the microorganisms, or try using a higher hydration ratio to boost activity.
Foul or Off Odor in the Sourdough starter
- Evaluate your feeding routine: Check if you’re feeding your sourdough starter often enough. A strong, unpleasant smell can indicate that the starter needs more frequent feedings.
- Discard and rebuild: If the off odor persists, you may consider starting over as it may be contaminated.
Hooch (Liquid) Separation
- Adjust feeding frequency: Hooch (a brownish liquid) that forms on top of your starter between feedings, indicates that the starter is hungry.
- Stir or pour off excess hooch: If hooch forms, stir it back into the starter or pour it off before feeding.
- Reduce hydration: If your starter consistently produces excessive hooch, try lowering the hydration level by using a lower water-to-flour ratio during feedings.
Mold Growth on Sourdough Starter
- Maintain cleanliness: Ensure that all equipment used for your starter is clean and free from any contaminants.
- Avoid cross-contamination: Store your starter away from other ferments or food sources that could introduce unwanted molds or bacteria.
- Discard and start fresh: If mold growth occurs, it’s best to discard the affected starter and begin a new batch using a thoroughly cleaned container and fresh ingredients.
Remember, sourdough starters can be resilient and may require some experimentation and adjustments to find the best practices for your specific environment and routine.
Now that you have a deeper understanding of sourdough starter maintenance, you’re ready to take your baking skills to new heights. Happy baking, fellow pastry enthusiasts!

Method
- Place a small bowl on the kitchen scale, tare to zero and measure 100 grams of water
- Remove, then set aside.
- Place another bowl on the kitchen scale, tare to zero and measure 100 grams of flour
- Remove, then set aside.
- Add the water and flour to the Starter Jar and mix until well combined.
- Note the time of this first feeding – this is what time every other feeding needs to happen.
- Cover with breathable cover and set in an out of the way space with a constant temperature around 70-75 degrees.
- After 24 hours you should see small bubbles and it may have an odor. This is the first sign of fermentation-its supposed to do this.
- Stir and place breathable cover back on. Rest for 24 hours.
- Discard 100 grams (half of the starter)
- Add in 100 grams of flour and 100 grams water.
- Stir to incorporate into the reserved starter.
- Cover with the cloth and mark the starter with the band to keep track of the level.
- Rest for 24 hours
- Follow the same process as day 3
- Discard 100 grams, Add 100 grams flour + 100 grams water
- Stir, cover with breathable cloth. Rest 24 hours
- By this time your starter should be doubling in size within 3-4 hours.
- An active starter will present with lots of large and small bubbles.
- The texture should be soft and spongy.
- The smell should no longer be pungent, it should be pleasant
