How often to feed sourdough starter in fridge

Feeding your sourdough starter while it’s in the fridge is crucial for maintaining its health. Generally, you should feed your sourdough starter once every 1-2 weeks. If you plan to bake more frequently, you can feed it weekly to keep it active. However, if you’re not baking as often, bi-weekly feeding is adequate to keep it alive.

When you feed a sourdough starter in the fridge, it’s important to remember a few key practices. Begin by removing your starter from the fridge and letting it come to room temperature for about an hour. After this, discard half of the starter and feed it equal parts water and flour. This process revitalizes the yeast and bacteria, ensuring robust fermentation.


Be aware that neglecting to feed your sourdough starter can lead to an imbalance, where the yeast becomes less active over time. You’ll notice it becomes less bubbly and may develop an off smell if left too long. To revive a neglected starter, simply increase the feeding frequency for a while until it regains its activity.

Want to keep your starter in optimum condition? Here are some tips:

  • Always use high-quality flour for feeding.
  • Store your starter in a clean, tightly sealed container.
  • Consider marking the container with feeding dates to remind you when to feed it next.
  • If you are unsure about its health, perform a float test to check the viability of the yeast.

Feeding schedules may vary depending on your baking frequency and the starter’s specific needs. Experiment a little to find what works best for you and your sourdough.
