What You’ll Learn
- What oven spring is.
- How fermentation affects it.
- Why shaping matters.
- What steam does.
- How scoring and oven heat contribute.
Quick Answer
Poor oven spring is commonly caused by overproofing, under-fermentation, weak dough strength, poor shaping, inadequate steam or insufficient oven heat. Review fermentation first because scoring cannot create strength that is not already in the dough.
This lesson is part of our Troubleshooting section: “Fix the most common sourdough problems.”
Fermentation
Both under- and over-fermentation can reduce oven spring.
Dough Strength
Gluten must be strong enough to hold expanding gases.
Shaping
Good surface tension supports vertical expansion.
Scoring
A clean score gives the dough somewhere to open.
Steam
Steam keeps the crust flexible during the expansion phase.
Oven Heat
A properly preheated oven and baking surface support rapid expansion.
From Our Workshop
When oven spring is poor, we rarely start by changing the score. We start by asking what the dough looked like before shaping.
Bake Slower Tip
Think of oven spring as a result, not a technique.
Common Mistake
Do not cut deeper and deeper hoping to force a weak loaf upward.
Today You Learned
- Fermentation is central to oven spring.
- Dough strength matters.
- Shaping supports height.
- Steam and heat help expansion.
- Scoring guides rather than creates rise.
Frequently Asked Questions
Does a deeper score increase spring?
Not necessarily.
Can overproofed dough spring?
Usually less.
Can underproofed dough spring too much?
It may burst unpredictably.
Do I need steam?
Yes, in some form.
Does preheating the Dutch oven matter?
Usually.
Make the Next Bake Easier
Better oven spring starts with fermentation and dough strength, then finishes with heat and steam.

Troubleshoot one variable at a time
Diagnose from the whole loaf, not one symptom. Compare dough strength, fermentation, proofing, scoring and bake together. Changing several stages at once can hide the real cause and make the next result harder to interpret.
