Causes & Solutions
Too long or too warm final proof (classic overproofing)
very commonSymptoms:
- • Dough rose then collapsed or flattened
- • Surface looks wrinkly and slack
- • Poke test: indent remains
Why does this happen?
When fermentation proceeds past peak, the gluten network weakens and gas escapes; yeast have consumed most fermentable sugars and acid production increases, causing collapse and stronger sourness [1][2].
🚨 Immediate Fix:
Reshape gently and bake immediately. Use a preheated Dutch oven or cloche to trap steam and support crust set.
📅 Long-term Fix:
Shorten proof time or proof at lower temperature; track dough with the poke test instead of clock time [1].
🧪 Test:
Poke test: overproofed dough doesn't spring back and the indent remains; this distinguishes overproofing from underproofing [2].
Excessive fermentation flavor (too sour, large irregular holes)
commonSymptoms:
- • Very tangy/sour crumb
- • Large, uneven alveoli
- • Gummy dense areas
Why does this happen?
Extended fermentation favors bacterial acid production over balanced yeast gas production, creating harsh acidity and uneven crumb structure [1].
🚨 Immediate Fix:
Bake now; flavor is intensified but bread is still edible. For milder flavor next time proof cooler or shorten bulk/final proof [1].
📅 Long-term Fix:
Adjust starter inoculation, fermentation time and temperature to balance yeast:bacteria activity; consider cooler retard in fridge to develop flavor without collapse [2].
🧪 Test:
Compare aroma and crumb to a correctly proofed loaf; over-fermented loaves show pronounced sourness and weakened structure [1].
Weak gluten / insufficient development
commonSymptoms:
- • Dough can't hold gas and collapses
- • Loaf spreads rather than rises in oven
Why does this happen?
If gluten network is weak (under-kneaded, low-protein flour, or too much hydration), it cannot contain gas once fermentation stress increases; what looks like overproofing can be structural weakness [1][2].
🚨 Immediate Fix:
Handle gently when shaping; bake in a Dutch oven to support oven spring and crust set.
📅 Long-term Fix:
Improve gluten: use stronger flour, stretch-and-fold during bulk, rest (autolyse) adjustments; measure hydration with a digital kitchen scale for repeatability.
🧪 Test:
Windowpane test after development: dough should stretch thin without tearing indicating sufficient gluten [1].
Excessive hydration or slack dough
mediumSymptoms:
- • Dough spreads on proofing surface
- • Difficult to shape, very sticky
Why does this happen?
High hydration weakens dough cohesion; during late fermentation bubble walls rupture and dough collapses under its own weight [2].
🚨 Immediate Fix:
Use a well-floured banneton proofing basket or parchment paper sling for final proof to support shape; reduce handling.
📅 Long-term Fix:
Reduce hydration slightly or build more gluten strength via folds and longer development phases; weigh ingredients on a digital kitchen scale.
🧪 Test:
If dough spreads even when cold, hydration is likely too high for your flour or technique [2].
Proofed too long before bake — poor oven spring
commonSymptoms:
- • Bread spreads in oven, scores don't open
- • Crumb is flat
Why does this happen?
Overproofed dough lacks the elasticity and remaining yeast activity needed for oven spring; steam can't expand a collapsed network [1].
🚨 Immediate Fix:
Bake immediately at a very hot start (use a preheated Dutch oven) to salvage some rise; ensure strong scoring with a bread lame to direct expansion.
📅 Long-term Fix:
Use cooler proofing or shorter times; test with the poke method and consider cold retard in the fridge to delay the final rise [1][2].
🧪 Test:
Scores that fail to open and a loaf that spreads are classic signs of overproofing, not lack of oven heat alone [1].
Starter imbalance (too much active starter or overly acidic)
mediumSymptoms:
- • Rapid rise then collapse
- • Excessive acidity in dough
Why does this happen?
A very strong starter can ferment dough too quickly; conversely an acidic starter can weaken gluten and speed collapse. Balance of yeast and bacteria matters for timing and strength [1][2].
🚨 Immediate Fix:
Use less starter next time or cool the dough to slow fermentation; for this batch, shape quickly and bake.
📅 Long-term Fix:
Adjust feeding schedule and inoculation ratio; keep starter at a predictable strength by feeding consistently in a clear straight-sided container so you can observe rise times.
🧪 Test:
Track your starter's doubling time at your room temperature to predict how much inoculation to use [1].
🆘 Can I save this dough?
Final proof collapsed but not rotten or spoiled
Solution: Reshape gently to degas, place in a hot preheated [Dutch oven](https://amzn.to/4sVhKhN) and bake immediately. Expect a flatter, more sour loaf; texture may be uneven.
Success chance: good for safety and flavor, moderate for appearance
Dough is very slack and won't hold shape
Solution: Turn into a free-form or pan loaf. Use a loaf pan to contain spread, or make focaccia-style flatbreads instead.
Success chance: good
Extremely sour or over-fermented
Solution: If flavor is too sour for slicing, use the baked bread for toast, croutons or breadcrumbs. For future bakes lower fermentation temperature or shorten times.
Success chance: high for reuse, low if you want a mild sourdough
Prevention
- ☐ Use a digital kitchen scale for consistent hydration and salt (salt ≈ 2% of flour weight).
- ☐ Control dough temperature: target 24–26°C (75–78°F) after mixing; use an instant-read thermometer to check.
- ☐ Judge by feel and poke test rather than clock: dough should spring back slowly, not stay fully indented.
- ☐ Strengthen gluten with folds during bulk or longer autolyse; perform windowpane test to confirm development [1].
- ☐ If timing is tight, use cold retard in the fridge for the final proof to prevent passing the peak [1][2].
- ☐ Use supportive proofing tools like a banneton proofing basket to maintain shape during final proof.
