The Basics of Sourdough Starters
What is a Sourdough Starter?
A sourdough starter is a mixture of flour and water that captures wild yeast and bacteria from the environment. This combination ferments over time, creating a living culture that is used to leaven bread. Unlike commercial yeast, which is a single strain of yeast, sourdough starter contains multiple strains of wild yeast and lactic acid bacteria, giving sourdough bread its unique flavor and texture.
Importance of Maintaining a Sourdough Starter
Maintaining a sourdough starter is crucial for ensuring its longevity and effectiveness. A well-maintained starter can last indefinitely, providing you with a continuous supply of natural leavening agent for your baking needs. Regular feeding and proper storage are essential to keep the microbial balance healthy and active.
Neglecting your starter can lead to issues such as mold growth, unpleasant odors, and weakened leavening power. Feeding your starter involves discarding a portion of it and replenishing it with fresh flour and water. This process provides the microorganisms with the nutrients they need to thrive.

Proper storage is equally important. While some bakers prefer to keep their starter at room temperature for daily use, refrigerating it can significantly extend its shelf life. Learn more about the benefits of refrigerating your starter in our article on storing sourdough starter in the fridge.
By understanding what a sourdough starter is and the importance of maintaining it, you can ensure that your starter remains healthy and active for many delicious bakes to come.
Storing Your Sourdough Starter
Proper storage is essential for maintaining the health and longevity of your sourdough starter. Let's explore the differences between fridge and room temperature storage, and the benefits of refrigerating your sourdough starter.
Fridge Vs. Room Temperature Storage
When it comes to storing your sourdough starter, you have two main options: refrigeration or keeping it at room temperature. Each method has its advantages and considerations.
| Storage Method | Frequency of Feeding | Ideal Usage |
|---|---|---|
| Room Temperature | Every 12-24 hours | Frequent baking |
| Fridge | Every 1-2 weeks | Infrequent baking |
- Room Temperature Storage: Keeping your sourdough starter at room temperature requires more frequent feedings, usually every 12 to 24 hours. This method is ideal if you bake often and need your starter to be active and ready to use on short notice.
- Fridge Storage: Refrigerating your sourdough starter slows down its activity, allowing you to feed it less frequently—typically every one to two weeks. This method is suitable for those who bake less often and prefer a more hands-off approach.

Reviving an Old Sourdough Starter
If your sourdough starter has been sitting in the fridge for a while, it may become dormant. However, with the right steps and care, you can revive it and bring it back to its bubbly, active state.
Steps to Revive a Dormant Starter
Remove from the Fridge: Take your sourdough starter out of the fridge and let it come to room temperature.
Discard and Feed: Discard about half of the starter. This helps to freshen it up and remove any excess acidity. Then, feed the remaining starter with equal parts of flour and water. For example, if you have 100 grams of starter, add 100 grams of flour and 100 grams of water.
Mix and Let Rest: Stir the mixture thoroughly until well combined. Cover loosely and let it rest at room temperature for about 12 hours.
Repeat Feeding: After 12 hours, discard half of the starter again and feed with equal parts of flour and water. Repeat this process every 12 hours until the starter becomes bubbly and active again.
Monitor Activity: Look for signs of fermentation such as bubbles, a rise in volume, and a tangy smell. This indicates that your starter is becoming active.
Tips for Success
Use Warm Water: Using slightly warm water (around 75-80°F) can help speed up the revival process.
Consistent Feeding: Maintain a regular feeding schedule to encourage activity. Consistency is key when reviving a dormant starter.
Proper Ratios: Stick to the 1:1:1 ratio (starter:flour:water) for best results. This balance ensures that your starter has enough food to thrive.
Patience: Revival can take a few days, especially if your starter has been dormant for a long time. Be patient and give it time to come back to life.
Use Whole Grain Flour: Occasionally using whole grain flour like rye or whole wheat can boost activity due to higher nutrient content.
