How to store sourdough starter in the fridge is the best option if you bake once or twice a week. When kept at a cool temperature, your starter slows down its activity, so you don’t need to feed it daily. Instead, you can follow a regular schedule, refreshing it about once a week. Before refrigerating, feed your starter and let it rise slightly at room temperature. Then, seal it loosely in a jar and place it in the fridge. If you’re unsure how to refresh it, check out our detailed guide on How to Feed a Sourdough Starter: Step-by-Step Feeding Guide.

Freezing for Long-Term Storage
How to store sourdough starter for several months without maintenance is easiest through freezing. To do this, feed your starter and let it become active, then spread a thin layer on parchment paper or place spoonfuls in a freezer-safe container. Once frozen, your starter will remain dormant but viable for future use. When you’re ready to revive it, thaw at room temperature and begin feeding again with fresh flour and water. Choosing the right flour is key to bringing it back to life, and you can learn more in our guide on Best Flour for Sourdough Starter: A Complete Beginner’s Guide.
Drying Your Starter for Long-Term Storage
How to store sourdough starter in its most reliable form is through drying. This method is perfect if you don’t plan to bake for months but still want a backup that never fails.
To dry, spread a thin layer of fully fed starter onto parchment paper and let it air-dry until it becomes brittle. Break it into flakes and keep them in an airtight jar. When you need to bake again, simply rehydrate the flakes with equal parts water and flour. This technique is not only the safest way for long-term preservation, but it also ensures your sourdough culture never dies.

Refrigerating for Short-Term Storage
How to store sourdough starter in the fridge is the easiest method if you plan to pause baking for a few weeks. Once your starter is active and bubbly, feed it, let it rise for a couple of hours at room temperature, then move it to the refrigerator in a clean jar. This slows down fermentation and allows you to feed it just once a week. When you’re ready to bake, take it out, throw away half of it, and mix in the same amount of flour and water. If you’re not sure how to feed correctly, follow our detailed guide on How to Feed a Sourdough Starter: Step-by-Step Feeding Guide for consistent results.
