Storing sourdough starter outside of a refrigerator requires a bit more attention and care, as the warmer temperatures can accelerate fermentation and affect the health of the starter. However, if you bake with your sourdough regularly and want to keep it at room temperature for convenience, here are some tips for successful storage:
Frequent Feedings: To keep the sourdough starter active and healthy, you'll need to feed it more frequently. The warmer temperatures will speed up fermentation, so you may need to feed the starter once or twice a day. Stick to a consistent feeding schedule to maintain its vigor.
Adjust Feeding Ratios: Consider adjusting the feeding ratios to moderate the fermentation. For example, reduce the proportion of starter to flour and water during feedings. Using less starter in the mix will slow down the fermentation process.
Use a Larger Container: If you typically keep a small amount of starter, consider using a larger container to provide more space for the starter to expand without the risk of overflowing.
Choose a Cooler Spot: While you want to keep the starter at room temperature, try to find a cooler spot in your kitchen away from direct sunlight and other heat sources. This can help reduce the impact of high temperatures.
Monitor Activity: Keep a close eye on your starter. If you notice that it's becoming too active or developing a strong acidic smell, consider increasing the feeding frequency or adjusting the feeding ratios accordingly.
Store in the Fridge When Inactive: If you don't plan to use the sourdough starter for an extended period (e.g., you're going on vacation), it's best to store it in the refrigerator, where the cold temperatures will significantly slow down fermentation. Before storing in the fridge, make sure the starter has been recently fed and is at its peak activity.
Remember, storing sourdough starter at room temperature requires more attention and diligence compared to refrigeration. If you find that it becomes challenging to maintain or it doesn't perform well at room temperature, consider reverting to refrigeration, which provides more flexibility and reduces the need for frequent feedings.
