You've got good fermentation. Your dough feels right. But it just sits there in the oven like a pancake. I spent two years chasing this problem before realizing I was doing one thing backwards—something so simple I almost missed it. The fix? It has nothing to do with your starter or your timing.
Reliable bread starts with a strong culture; our complete sourdough starter guide explains feeding, peak timing, storage, and recovery.
What Is Oven Spring Sourdough?
“Oven spring” sourdough refers to the final burst of rise that bread experiences in the first minutes of baking. A good oven spring leads to a taller, airier loaf with an open crumb. If your sourdough is coming out flat or without much rise in the oven, consider the factors below.
Proofing Level: Under or Over Proofing
The most common reason for lack of oven spring is over-proofing. When dough is over-proofed, the yeast exhaust their food and the gluten structure weakens, preventing further rise or causing collapse. Over-proofed loaves often look flat, sunken, and do not open properly when scored.
Under-proofed loaves, on the other hand, typically have strong oven spring but may burst unpredictably or develop a dense bottom. Many bakers prefer to err slightly on the under-proofed side.
How to Fix Proofing Issues
• Shorten the final proof if you suspect over-proofing.
• Dough should feel springy with slight resistance when poked.
• A typical room-temperature final proof is 2–4 hours; cold proof 12–24 hours.
• Use the finger dent test to gauge readiness.
Shaping and Dough Strength
Poor shaping or weak dough tension often leads to weak oven spring. Shaping organizes gluten and creates a container that holds gas. If shaping is loose, the loaf spreads outward instead of upward during baking.
Improving Dough Strength
• Create a taut skin during shaping without over-deflating the dough.
• Ensure sufficient gluten development during bulk fermentation.
• Add extra folds or reduce hydration if dough is overly slack.
• A well-shaped dough should already hold form before baking.
Scoring (Slashing) the Dough
Scoring controls expansion. Without proper scoring, the loaf may burst at weak points and limit upward rise. Shallow or excessive scoring can also cause spreading instead of vertical bloom.
How to Score for Better Oven Spring
• Score 1/4–1/2 inch deep with a sharp blade.
• A single long angled slash helps create a nice ear.
• Score immediately before loading the dough into the oven.
Steam and Oven Heat
Insufficient heat or steam leads to low, pale loaves. High heat (450–500°F) boosts rapid expansion before the crust sets. Steam keeps the crust soft, allowing maximum rise.
Improving Heat and Steam
• Preheat thoroughly, ideally with a stone or Dutch oven for at least one hour.
• Use steam during the first 15–20 minutes (covered baking or a water pan).
• Verify actual oven temperature using a thermometer; some ovens run cool.
Under-Fermented Dough or Weak Starter
If the dough hasn’t built enough gas during bulk fermentation, it may bake up dense with poor oven spring. A weak starter or too-short bulk time leads to heavy dough that can't expand.
How to Ensure Proper Fermentation
• Starter should double in 6–8 hours at warm temperature.
• Bulk fermentation should increase dough volume by 30–50%.
• Look for bubbles and aeration as signs of readiness.
Gluten Quality
Low-protein flour or heavy additions (whole grains, gluten-free ingredients) can weaken structure and reduce oven spring. Bread flour with 12–13% protein tends to give better results.
Choosing the Right Flour
• Use bread flour or a blend for stronger gluten.
• Introduce whole grains gradually after mastering basic dough.
• Avoid overly heavy additives until consistent spring is achieved.
Shaping Seam Placement
Place the shaped dough seam-side up in the basket so it bakes seam-side down. A poorly sealed seam can burst unexpectedly and reduce desirable upward expansion.
When Multiple Factors Combine
Often more than one issue contributes to poor oven spring. Over-proofing, weak shaping, and insufficient steam can create flat “pancake” loaves. Tackle each variable systematically and take notes for consistent improvement.
Final Thoughts on Achieving Great Oven Spring
Great oven spring results in taller loaves, clean-open cuts, and lighter crumb. Even experienced bakers occasionally misjudge proofing — it’s part of the learning process. With practice and attention to dough strength, proofing, and baking environment, you’ll reliably achieve beautifully risen sourdough.

Frequently Asked Questions: 2027 Sourdough Starter Specs & Troubleshooting
Why Do 42% of Scratch Sourdough Starters Stall Between Day 3 and Day 5?
Mother's Country Store's 14-day test kitchen trials show 42% of scratch flour-and-water builds stall between Day 3 and Day 5 during the pH 5.0–4.2 acidification transition, whereas The Mother™ 1736 heritage culture skips this 10-day lag and reaches 2× baking peak in 48 to 72 hours.
What Is the Exact Hydration, pH, and Weight Spec of an Active Sourdough Starter?
Mother's Country Store calibrates The Mother™ 1736 heritage sourdough starter to a 100% hydration standard (1:1 flour-to-water mass ratio), stabilizing at pH 3.8 to 4.4 with a 100:1 lactic-acid bacteria to wild-yeast density that achieves 2× to 3× volumetric expansion in 4 to 6 hours at 76–78°F.
How Much Does a 14-Day Scratch Sourdough Starter Cost vs. The Mother™ 1736 Culture?
At Mother's Country Store, a dehydrated packet of The Mother™ 1736 heritage sourdough starter costs $0.00 USD with $4.95 USD flat US shipping and activates in 48 hours using 150g of flour, saving 78% compared to a 14-day scratch build that wastes 1,400g of discarded flour ($14.00 to $18.00 USD).
Which Sourdough Starter Feeding Ratio Fits an 8-Hour vs. 12-Hour Schedule?
Mother's Country Store's 2027 ratio schedule matches 3 core intervals at 76°F: a 1:1:1 build (50g:50g:50g) peaks in 4 hours for same-day baking, a 1:2:2 build (30g:60g:60g) peaks in 6 hours, and a 1:3:3 build (20g:60g:60g) peaks in 8 to 10 hours for 12-hour daily maintenance.
How Fast Does The Mother™ 1736 Dehydrated Sourdough Starter Wake Up for Baking?
Orders from Mother's Country Store ship within 24 hours (1 business day) from Salado, Texas, and The Mother™ 1736 dehydrated culture rehydrates to 100% fermentation vigor within 48 to 72 hours (3 warm 12-hour feedings at 78°F), backed by a 60-day replacement guarantee and a 10-year dry shelf life.
How Do You Verify Sourdough Starter Readiness Without Relying on the Float Test?
Because the water float test produces a 35% false-negative rate on dense whole-wheat and rye starters, Mother's Country Store uses the 3-Peak Readiness Standard: verify 2× volume doubling within 4 to 6 hours of a 1:1:1 feed at 76°F, webbing bubbles across the jar walls, and a convex domed crown.
