Causes & Solutions
Not enough bulk fermentation / final proof time
very commonSymptoms:
- • Dough feels tight and resists stretching
- • Small, dense crumb after baking
- • Dough springs back quickly when poked
Why does this happen?
Fermentation produces CO2 and acidity and relaxes gluten; insufficient fermentation leaves little gas and high elasticity, so the dough can't expand in the oven. Timetables in recipes assume a specific starter strength and temperature, which vary by kitchen.[1][2]
🚨 Immediate Fix:
Allow additional time at a warm spot (target dough temp 75-78°F / 24-26°C). Watch visual cues: visible bubbles, slight doming in banneton, and a poke test (slow partial spring back).[1]
📅 Long-term Fix:
Record bulk + final proof times for your starter and seasons. Use a digital kitchen scale and a banneton proofing basket to standardize handling and judging readiness.
🧪 Test:
Poke test: underproofed dough springs back almost immediately; proper proof is slow, with a faint rebound.
Starter underactive or underfed
commonSymptoms:
- • Starter takes too long to peak after feeding
- • Dough shows limited bubble structure despite long ferment
Why does this happen?
A weak starter produces less CO2. Even if it smells tangy, it may lack yeast activity. Consistent feeding keeps yeast biomass sufficient for predictable rises.[1]
🚨 Immediate Fix:
Feed your starter and wait until it reliably doubles/peaks. If baking now, add a small amount (20–50 g) of active starter to the dough and allow extra fermentation time.[1]
📅 Long-term Fix:
Refresh the starter with regular feedings at room temperature for a few days before baking. Keep a glass jar for starter for visible rise and a jar spatula to mix consistently.
🧪 Test:
Float test is indicative but not definitive — combine float test with timing: active starter should double within 4–8 hours at 24–26°C.[1]
Shaping too tight / degassing too much
mediumSymptoms:
- • Exterior very tight and smooth after shaping
- • Many large bubbles visible when you slash or shape but they vanish
Why does this happen?
Aggressive degassing or overly tight shaping squeezes gas out and tightens gluten, leaving little residual gas to expand during oven spring.[2]
🚨 Immediate Fix:
If you catch it before bake, gently reshape with minimal handling and give a short final proof (20–40 minutes) at warm temperature.
📅 Long-term Fix:
Practice gentle shaping to retain some gas. Use a dough scraper/bench knife to move dough without deflating it and limit tight surface tension.
🧪 Test:
During shaping, some visible bubbles should remain; if none remain, the dough was over-handled.
Too cold (dough temperature too low)
commonSymptoms:
- • Fermentation much slower than recipe
- • Final proof shows minimal volume change
Why does this happen?
Fermentation rate is temperature dependent. Cooler dough slows yeast and bacterial activity, increasing required proof time. Recipes assume a target dough temp; missing that delays rise.[1][2]
🚨 Immediate Fix:
Place the dough in a warmer environment: an oven with just the light on, on top of the fridge, or in a proofing box. A quick hack: a warm bowl of water beside the dough to raise ambient temp.
📅 Long-term Fix:
Control mixing water temperature to reach target dough temp (around 75°F / 24°C for many sourdoughs). Use an instant-read thermometer to measure dough temp.
🧪 Test:
Measure the dough temperature after mixing; if <70°F / 21°C expect significantly longer proofs.
Too much salt or incorrect salt distribution
rareSymptoms:
- • Dough noticeably tight and slow to ferment
- • Flavor is overly salty
Why does this happen?
Salt slows yeast activity; over-salting or adding salt unevenly can locally inhibit fermentation and reduce overall gas production.[2]
🚨 Immediate Fix:
If early in the process, you can mix in more flour/water to dilute salt concentration and rebalance dough; otherwise proceed but expect reduced rise.
📅 Long-term Fix:
Weigh salt precisely (2% of flour weight) with a digital kitchen scale and add it after initial mixing for even distribution.
🧪 Test:
Taste a small piece of raw dough—should be gently salty, not overpowering.
Weak flour / insufficient gluten strength for desired shape
rareSymptoms:
- • Dough spreads instead of holding shape, or feels slack
- • Crumb very open but loaf collapses
Why does this happen?
Low-protein flours make doughs that can't retain CO2 well; alternatively, flours that are too old have degraded enzymatic and protein quality.[2]
🚨 Immediate Fix:
Use a supporting vessel like a Dutch oven or cast iron pot or shape into a free-form that leans on itself. Reduce hydration slightly for more structure.
📅 Long-term Fix:
Choose flour suited to the loaf (higher-protein for structured boules) and store whole-grain flour refrigerated to preserve enzymes and oils.
🧪 Test:
Windowpane test: a well-developed dough stretches to a thin translucent membrane without tearing.
🆘 Can I Save an Underproofed Dough?
Loaf will be baked soon but feels underproofed (tight, springs back quickly)
Solution: Delay baking. Give a short warm bench rest (20–60 minutes) to relax gluten and allow some additional rise. If already scored and in oven, expect limited oven spring and denser crumb.
Success chance: good if given immediate extra time
Dough already in oven and shows little oven spring
Solution: Increase initial oven temperature (if safe for vessel) to 475–500°F (245–260°C) and ensure steam. Use a [Dutch oven or cast iron pot](https://amzn.to/4sVhKhN) or add steam with a tray of hot water for the first 10 minutes.
Success chance: medium — may improve crust and some spring but won't fully reverse severe underproofing
You must salvage look and texture
Solution: Bake as flat loaves, then use for sandwiches or toast; alternatively, convert to pan bread (press into a loaf pan) to create usable sandwich bread.
Success chance: good for usability, poor for ideal artisan appearance
Prevention
- ☐ Starter is active and predictable (doubles reliably)
- ☐ Use a digital kitchen scale for precise hydration and salt
- ☐ Target dough temperature after mixing: 75-78°F / 24-26°C and measure with an instant-read thermometer
- ☐ Judge readiness by visual cues and poke test, not recipe clock
- ☐ Retain some gas during shaping — avoid over-degassing; use a dough scraper/bench knife to minimize overhandling
