How long does it take for sourdough bread to mold?

The time it takes for sourdough to mold depends on various factors, including the storage environment, temperature, and humidity. Here's a general timeline for sourdough bread:

1. Room Temperature (70-77°F/21-25°C): Without refrigeration, sourdough bread can stay fresh and safe from mold for 1-2 days at room temperature.

2. Refrigeration (Below 40°F/4°C): Sourdough bread can last up to 7-10 days in the fridge. Lower temperatures slow down microbial growth, including mold.

3. Freezing: Sourdough bread can be kept frozen for longer storage. It can last for several weeks or up to a few months in the freezer. Proper wrapping is essential to prevent freezer burn.

Here are additional tips to prevent sourdough bread from molding:

1. Use Clean Utensils: Ensure that the tools and utensils used to handle the dough are clean.

2. Store Properly: Keep sourdough bread in a bread box, a tightly sealed plastic bag, or wrapped in a clean cloth to minimize exposure to air and moisture.

3. Check Regularly: Even under optimal storage conditions, check your sourdough bread periodically for any signs of mold growth.

4. Don't Cut and Store: To prevent the risk of mold spreading inside the loaf, slice the bread only as needed and avoid storing the remaining loaf with cut sides exposed.

5. Avoid Extreme Temperatures: Keep sourdough bread away from direct heat sources or excessively humid areas to prevent condensation.

6. Watch for Changes: Pay attention to texture, smell, and appearance for signs of spoilage. Discard any bread that has visible mold or an off odor.

Remember, it's always best to follow food safety guidelines and consume your sourdough bread within a reasonable timeframe to ensure freshness and quality. When in doubt, it's better to discard any bread that shows signs of mold or spoilage.
