Sourdough Not Rising – 7 Causes & Solutions

Your sourdough or dough isn't rising? Here are the most common causes and what you can do RIGHT NOW.

Quick Diagnosis

WHAT exactly isn't rising?

My starter My dough during bulk fermentation My dough during final proof My bread in the oven (no oven spring)

Causes & Solutions

Starter isn't active enough

very common

Symptoms:

  • • Starter barely bubbles
  • • No volume increase after feeding
  • • Starter smells more like vinegar than yeast

Why does this happen?

A healthy starter should double within 4-8 hours after feeding; without frequent feeding the yeast population and enzyme balance decline and gas production falls off [1][2][5].

🚨 Immediate Fix:

Don't use it yet. Perform repeated feedings (1:2:2 or 1:3:3, depending on starter strength) at 24–26°C until it reliably doubles in 4–6 hours. Weigh feedings on a kitchen scale for consistency [1][2].

📅 Long-term Fix:

Keep a predictable feeding schedule and storage method (room-temperature daily or refrigerated with weekly refresh). Track how your starter behaves in your kitchen; record doubling times and peaks [1][5].

🧪 Test:

Float test: a spoonful of active starter should float in water—use this alongside volume observations rather than as the sole test [2][6].

Too cold

common

Symptoms:

  • • Fermentation takes much longer than recipe states
  • • Dough feels cool to touch
  • • Room temperature below 68°F / 20°C

Why does this happen?

Microbial activity is temperature-dependent; cold slows yeast and bacteria so fermentation can take many times longer. Aim for a dough temperature around 75–78°F (24–26°C) for typical sourdough activity [1][2][12].

🚨 Immediate Fix:

Move dough to a warmer spot: oven with light on, top of fridge, or a proofing area. You can also use slightly warmer water when mixing—adjust to reach target dough temperature—and measure with an instant-read thermometer [2][12].

📅 Long-term Fix:

Calculate water temperature to hit a desired dough temperature and consider a proofing box or insulated container to stabilize temps across seasons [2][7].

🧪 Test:

Measure dough temperature during bulk fermentation; 24–26°C is a practical target for predictable timing [1][2].

Not enough time

common

Symptoms:

  • • Recipe times have elapsed but the dough shows little change
  • • Dough lacks bubbles and doming

Why does this happen?

Published times assume a specific starter strength, flour, and temperature. Your environment and starter change the timeline—use indicators (volume increase, bubbles) instead of the clock [2][7].

🚨 Immediate Fix:

Be patient and watch for visual signs: 50–75% rise in bulk, airy surface, and more extensible dough. If unsure, give it another fold and 30–60 minutes more [4][11].

📅 Long-term Fix:

Record your typical bulk and final proof times across seasons so you can adjust recipes reliably for your kitchen [2][7].

🧪 Test:

Use photographs to compare progress and the poke test (see cause-5) rather than strict hours [6][2].

Too much hydration or weak gluten structure

common

Symptoms:

  • • Dough spreads rather than holds shape
  • • Open, but collapsed crumb or very flat loaf

Why does this happen?

Over-hydrated doughs or insufficient gluten development can't trap gas effectively. High hydration weakens the network; low-protein flour makes it worse [3][4].

🚨 Immediate Fix:

Reduce hydration next bake (try ~70–72% initially) and perform more effective strength-building folds (4–6 sets during bulk) with a dough scraper to avoid gas loss [3][4].

📅 Long-term Fix:

Use higher-protein bread flour (12–14%) or blend whole-grain with white bread flour. Develop gluten via autolyse and systematic stretch-and-folds [4][3].

🧪 Test:

Windowpane test and coil-fold readiness: dough should hold thin sheets without tearing; if it fails, increase folds or reduce hydration [3][7].

Over-proofed – dough has collapsed

medium

Symptoms:

  • • Dough rose then sank back
  • • Wrinkled surface, strong acidic smell
  • • Dough fails poke test (indent doesn't spring back)

Why does this happen?

When fermentation goes too far the gluten network weakens and yeast exhausts available sugars; gas escapes and the dough collapses [5][11].

🚨 Immediate Fix:

Reshape gently and bake immediately. Expect reduced oven spring and a more sour, denser loaf but still edible [5].

📅 Long-term Fix:

Shorten proof times, cool final proof, or proof at a lower temperature. Use the poke test to judge readiness rather than volume alone [6][2].

🧪 Test:

Poke test: a light indented area should slowly spring back; if it doesn't, the dough is likely over-proofed [6][5].

No oven spring

medium

Symptoms:

  • • Dough rose in proof but doesn't expand in oven
  • • Scores remain closed, loaf looks flat

Why does this happen?

Oven spring requires live yeast, steam to delay crust set, and sufficient dough elasticity. Over-proofing, lack of steam, or insufficient pre-bake strength all reduce oven spring [6][4].

🚨 Immediate Fix:

Preheat oven hotter (250–260°C / 480–500°F if safe for your pot), bake in a preheated Dutch oven or use steam for the first 10–15 minutes; slash dough properly with a bread lame to direct expansion [6][4].

📅 Long-term Fix:

Build more strength during bulk fermentation, don't over-proof, and use equipment that traps steam (Dutch oven or cloche) for reliable spring [4][6].

🧪 Test:

Good oven spring shows rapid expansion and open scoring in the first 10 minutes of bake [6].

Old or weak flour

rare

Symptoms:

  • • All other variables checked but dough still weak
  • • Flour smells stale, rancid, or musty

Why does this happen?

Flour enzymes and whole-grain oils degrade over time; rancid flour reduces fermentation energy and can alter dough behavior [7][11].

🚨 Immediate Fix:

Replace flour with a fresh bag and retest the recipe.

📅 Long-term Fix:

Store white flour in a cool, dark place and keep whole-grain flour refrigerated or frozen to preserve oil quality [7].

🧪 Test:

Smell and small test batch: fresh flour smells neutral to slightly sweet; if in doubt, purchase a small bag of fresh bread flour to compare [7].

🆘 Can I save this dough?

Dough has sat 6+ hours and nothing is happening

Solution: Mix in ~50g active, bubbly starter (increase proportionally) and fold thoroughly; warm the environment to 24–26°C and wait 2–3 hours. This can jump-start fermentation if the starter was the limiting factor [1][2].

Success chance: medium

Dough is over-proofed and collapsed

Solution: Degas gently, reshape, proof briefly in a cooler environment and bake in a hot, steam-trapping vessel. Expect a denser, more sour loaf but it's edible [5][6].

Success chance: good for taste, poor for volume

I used too much salt

Solution: If salvageable, dilute by adding an equal-mass salt-free dough and mix; otherwise use the dough for savory items (flatbreads, crackers) or dry and grind for seasoned breadcrumbs.

Success chance: labor-intensive

Prevention

  • ☐ Starter is active (passes float test and reliably doubles in 4–8 hours)
  • ☐ Dough temperature after mixing: 75–78°F / 24–26°C
  • ☐ Salt weighed (≈2% of flour weight) using a kitchen scale
  • ☐ Judge fermentation by visual signs (bubbles, 50–75% volume increase), not just the clock
  • ☐ Build gluten with autolyse and 4–6 sets of stretch-and-folds using a dough scraper
  • ☐ Use higher-protein bread flour when structure is weak
