Oven Spring
Oven spring is the dramatic final surge of rise a loaf makes in the first minutes of baking. As the dough heats, trapped gases expand, the yeast gives one last burst of activity, and the water inside turns to steam — all pushing the loaf upward until the crust sets and locks the shape in place.

What it is
For a brief window at the start of the bake, three things happen at once. The carbon dioxide already dissolved and trapped in the dough expands rapidly as it warms; the yeast, briefly energised by the rising heat before it dies off, ferments in a final flurry; and the water in the dough begins to turn to steam, which takes up far more space than liquid. Together they inflate the loaf faster than at any point during proofing.
Why it ends when it does
Oven spring isn't endless — it stops the moment the crust firms and sets. Heat dries and stiffens the outer layer into a rigid shell, and once that shell can no longer stretch, the rise is over regardless of what's happening inside. The whole event is brief: the loaf you pull out is essentially the shape it reached in those first minutes.
What decides how much you get
Proofing level is the biggest lever. An underproofed loaf still has lots of unexpanded gas potential and springs hard; an overproofed one has spent its gas and yeast already, so it barely lifts. Scoring is the other: the cuts give all that expanding gas a controlled path to open, so a well-scored loaf blooms upward while an unscored one bursts at a random weak point. Trapped steam also drives spring, which is why bakers keep the oven humid early on.

The tall, open crumb of an LME sourdough loaf is oven spring made visible — the pay-off for careful proofing and a confident score just before it goes in.

Frequently Asked Questions
What is oven spring in bread baking?
It's the rapid final rise a loaf makes in the opening minutes of baking. Heat makes the trapped gases expand, the yeast fires one last time, and water flashes to steam — all lifting the loaf until the crust sets and stops the rise.
Why did my bread get almost no oven spring?
The usual cause is overproofing: a dough left to ferment too long has already used up its gas and yeast energy, leaving little for the oven. Weak shaping, timid scoring and a dry oven can all reduce spring too, but proofing level is the first thing to check.
How does scoring affect oven spring?
Scoring gives the surge of expanding gas a chosen path to escape, so the loaf blooms upward along your cuts. Without it, that energy still forces its way out — but at the crust's weakest point, usually as a ragged burst rather than a clean, tall rise.
