Temperature Control for Sourdough – Manage Fermentation and Crumb

Practical guide to controlling temperature throughout the sourdough process: starter, bulk fermentation, proofing and baking. Science-backed tactics to get consistent results.

Why This Technique?

Temperature controls the speed of yeast and bacteria; small changes change flavor, rise and crumb.

Sourdough fermentation is temperature-dependent: higher temperatures accelerate yeast and bacterial metabolism, producing faster gas production and more lactic/acetic acid balance shift; lower temperatures slow activity and favor longer flavor development and better oven spring control [1][2]. Managing temperature is the most reliable way to predict timing and flavor outcomes in your bake [1][2].

✓ Predictable schedule and repeatability ✓ Control over crumb openness and acidity ✓ Ability to manipulate flavor through time vs. temperature ✓ Reduced risk of overproofing
