How to Keep Your Sourdough Starter Strong in the Heat

Written By Keelia Curtis

Summer heat can make your sourdough starter feel unpredictable—but it’s actually just more active.

You may notice:

  • Faster rise and fall

  • Stronger smell

  • More frequent feeding needed

To keep it balanced:
✔ Feed more frequently (every 12–24 hours)
✔ Store in a slightly cooler spot if needed
✔ Don’t let it sit too long after peak

A well-maintained starter makes everything else easier.

🌾 This is one of the first things we help troubleshoot in class so you can feel confident from the start.
