How to store sourdough starter in fridge

Storing sourdough starter in the fridge is a practical way to keep it healthy while reducing the frequency of feedings. Here’s how to do it effectively:

1. Feed your sourdough starter

Before refrigeration, make sure your starter is well-fed. Use equal parts flour and water to refresh it about 2-3 hours before storage, ensuring it’s at its peak activity.


2. Transfer to a jar

Transfer your fed starter into a clean glass or plastic jar with a loose-fitting lid. A mason jar works perfectly. Avoid airtight containers, as gas buildup can cause spills.

3. Label your jar

Label the jar with the date. This way, you can keep track of when you started storing it. A sharpie or masking tape will work well for this.

4. Refrigerate your starter

Place the jar in the fridge. The cooler temperature slows down fermentation while keeping the starter dormant, allowing you to space out feedings to about once a week.

5. Remember to feed

When you take your starter out of the fridge, feed it again before using it. Remove the desired amount, and re-feed with fresh flour and water.

6. Best practices for long-term storage

  • It’s okay to keep your starter in the fridge for several weeks, but always check for signs of discoloration or off smells.
  • For long-term storage, consider freezing a portion of your starter, which can be revived later.

Following these steps ensures your sourdough starter remains healthy and ready for baking goodness whenever needed. Embrace the art of sourdough, and enjoy fresh bread at your convenience!
