Sourdough Starter Care: What’s the Minimum Feeding Schedule?

Understanding Starter Health Indicators

To determine if your sourdough starter needs feeding, look for signs of activity and health. Check for bubbles on the surface, a slightly sour smell, and a gentle rise in the starter’s volume. If you notice these signs, it’s likely the starter needs feeding. The frequency of feeding depends on storage conditions, usage, and the type of starter. Generally, a starter that’s active and healthy can survive on a once-a-week feeding schedule.

Feeding Techniques for Minimum Schedule

When feeding your sourdough starter on a minimum schedule, use a 1:1:1 ratio of flour to water to starter. For example, if you have 100 grams of starter, add 100 grams of flour and 100 grams of water. Mix the ingredients gently to create a smooth, consistent batter. It’s essential to maintain a balanced ratio of flour to water to stimulate yeast and bacterial growth.

Storing the Starter Between Feedings

Between feedings, store your sourdough starter in an airtight container in the refrigerator at a temperature between 39°F and 45°F (4°C and 7°C). This will slow down the starter’s activity, allowing it to conserve energy and maintain its health. Before storing, make sure to feed the starter one last time to ensure it’s healthy and active.
