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 a feeding; regular feedings keep yeast populations robust and the bacteria/yeast balance stable [1].

🚨 Immediate Fix:

Wait to bake. Feed your starter 2–3 times daily at a 1:2:2 ratio using room-temperature water and flour and aim for a feeding temperature around 75–78°F / 24–26°C to speed activity [1].

📅 Long-term Fix:

Establish a consistent feeding schedule: daily at room temperature or weekly in the fridge; track rise times so you know when your starter is reliably at peak activity [1].

🧪 Test:

Float test: a spoonful of active starter should float in water — it's a quick indicator of gas production but not a guarantee of leavening power [1].

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?

Fermentation rate is strongly temperature-dependent: cooler dough slows yeast and bacterial metabolism, lengthening bulk and final proof times [1].

🚨 Immediate Fix:

Move dough to a warmer spot: an oven with the light on, top of the fridge, or a microwave with a cup of hot water to raise ambient temperature slightly [1].

📅 Long-term Fix:

Control dough temperature by adjusting water temperature and using a digital kitchen scale to weigh ingredients; track your typical room temps and adapt timing [1].

🧪 Test:

Measure dough temperature with an [instant-read thermometer](https://amzn.to/49Xsgwp) — aim for a finished dough temp around 75–78°F / 24–26°C for most sourdoughs [1].

Not enough time

common

Symptoms:

  • • Recipe times pass and dough shows little change
  • • Impatience (happens to all of us)

Why does this happen?

Recipe timings are based on specific starter strength, flour, and room temperature; they are guidelines, not absolute rules. Your conditions will change the clock [1].

🚨 Immediate Fix:

Be guided by visual signs: increased volume, bubbles, and a slightly domed surface — not the clock. Photograph the dough after mixing to compare later [1].

📅 Long-term Fix:

Record realistic times for your starter and kitchen across seasons so you can predict bulk and proof durations accurately [2].

🧪 Test:

Use simple volume comparisons (photo or marking container) and the feel test: dough that springs back slowly and retains some indent has proofed appropriately [2].

Too much salt or salt added too early

medium

Symptoms:

  • • Dough tastes very salty
  • • You accidentally doubled the salt

Why does this happen?

Salt controls fermentation at normal doses (~2% of flour weight) but inhibits yeast at higher concentrations; it slows enzymatic activity and yeast metabolism [2].

🚨 Immediate Fix:

If you suspect too much salt, you can attempt to dilute by adding unsalted flour and water to rebalance dough, but this changes hydration and structure [2].

📅 Long-term Fix:

Always weigh salt with a digital kitchen scale. Aim for ~2% salt of total flour weight; document how many grams your preferred salt yields per teaspoon to avoid inconsistency [2].

🧪 Test:

Taste a small piece of raw dough: it should be gently salty, not overwhelmingly so.

Over-proofed – dough has collapsed

medium

Symptoms:

  • • Dough was risen, now smaller again
  • • Surface collapsed or wrinkly
  • • Strong sour smell

Why does this happen?

When fermentation outpaces gluten strength, gas escapes and the network collapses; yeast may have exhausted fermentable sugars leading to deflation and strong acidity [1][2].

🚨 Immediate Fix:

Reshape gently and bake immediately. The loaf will be flatter and more sour but still edible; scoring may not open as expected [2].

📅 Long-term Fix:

Shorten proof times, proof at cooler temps, or retard in the fridge to gain control. Learn to use visual cues (doming, jiggle) instead of strict timing [1].

🧪 Test:

Poke test: press a fingertip gently — over-proofed dough will not spring back and the indent remains.

No oven spring

medium

Symptoms:

  • • Dough rose well, but nothing happens in oven
  • • Bread is flat
  • • Scores don't open (no 'ear')

Why does this happen?

Oven spring requires live yeast, trapped steam, and elastic dough. If dough is over-proofed, dry, or lacks surface tension, scoring won't open and the characteristic 'ear' won't form [1][2].

🚨 Immediate Fix:

For the next bake: preheat to high temperature (480°F/250°C+ for cast-iron or Dutch oven), create steam (use a Dutch oven or cast iron pot or add steam to the oven), and avoid over-proofing [1].

📅 Long-term Fix:

Develop stronger surface tension at shaping, score with a sharp bread lame/scoring tool at a shallow angle, and use a banneton proofing basket to support shape during final proof [2].

🧪 Test:

Cut a small score and see if it opens within the first 10 minutes of baking; lack of opening indicates poor oven spring.

Old/weak flour

rare

Symptoms:

  • • Everything else is right but dough won't rise
  • • Flour is over 1 year old
  • • Flour smells rancid or musty

Why does this happen?

Whole-grain flours contain oils that oxidize and go rancid; enzyme and nutrient levels decrease over time, reducing yeast nourishment and dough strength [2].

🚨 Immediate Fix:

Replace flour with a fresh bag and compare results.

📅 Long-term Fix:

Store flour cool and dark; keep whole-grain flours in the fridge or freezer to preserve freshness [2].

🧪 Test:

Smell and taste a small amount of flour — fresh flour smells neutral or slightly sweet.

🆘 Can I save this dough?

Dough has sat 6+ hours and nothing is happening

Solution: Stir in 50 g active starter (fed and bubbly) to reintroduce yeast — mix gently, let rest 2–3 hours at warm temp, then proceed with shaping.

Success chance: medium

Dough is over-proofed and collapsed

Solution: Degas gently, reshape, and bake immediately. Expect a denser crumb and more acidity but still tasty bread.

Success chance: good for taste, bad for appearance

I used too much salt

Solution: Make a fresh, salt-free dough and combine with the salty dough to dilute salt; otherwise repurpose the dough as crackers or breadcrumbs.

Success chance: labor-intensive

Prevention

  • ☐ Starter is active (float test passes and it reliably doubles after feeding) [1]
  • ☐ Dough temperature after mixing: 75–78°F / 24–26°C — measure with an instant-read thermometer [1]
  • ☐ Salt weighed precisely (≈2% of flour weight) using a digital kitchen scale [2]
  • ☐ Use proper shaping to build surface tension and a banneton proofing basket for support during final proof [2]
  • ☐ Use a dough scraper/bench knife for clean folds and shaping to protect gluten structure
