Troubleshooting

Sourdough Doughy Center? The Real Causes and Fixes

A gummy interior is rarely an underbaking problem. It's usually under-fermentation or cutting too soon.

Sam Ellsworth3 min read

Short answer: if your sourdough has a doughy center, it's usually under-fermentation or cutting before the loaf finished setting. Bake longer rarely fixes it; the dough wasn't ready for the oven.

What "doughy center" actually is

You slice into a beautiful loaf and find a wet, dense, slightly translucent layer in the middle. The crumb around it looks fine.

This is sometimes called:

  • Gummy crumb
  • Wet center
  • Heavy spot

Internal temperature was probably above 200°F. The bake wasn't short. So why is it doughy?

The 4 causes ranked

1Cut too soonDid you slice within 90 min?
2Under-fermentedDid the dough rise visibly?
3Overhydrated for flourWas hydration >75% on a soft flour?
4Underbaked despite tempDid internal temp hit 205°F+?

1. Cut too soon

Sourdough finishes baking as it cools. The starches gelatinize during the bake but only set fully as the loaf sits.

Cut within 30 minutes of bake → wet, gummy center. Cut within 90 minutes → may still feel slightly wet. Cut after 2 hours → fully set crumb.

The hardest part of sourdough is waiting. Always wait at least 90 minutes before cutting; ideally 2–3 hours.

2. Under-fermented

If the dough went into the oven without enough fermentation:

  • Yeast hadn't produced enough gas to fully aerate the crumb
  • Bacteria hadn't broken down enough starches
  • The center stays dense and wet

How to spot:

  • Dough rose less than 50% in bulk
  • Final crumb is tight elsewhere (not just the center)
  • Sourness is mild

Fix: extend bulk to 60–75% rise at 75°F.

3. Overhydrated for the flour

A 12% protein bread flour handles 78% hydration. A 9% protein all-purpose flour at 78% is too wet — the gluten can't hold it and the center collapses into a wet layer.

FlourMax recommended hydration
All-purpose (9–10%)65%
Bread (12–13%)80%
Strong bread (14%)85%
Whole wheat (13%)78%

Drop hydration if you're not sure of your flour's protein.

4. Internal temperature

Internal temp should reach 205–210°F for fully baked sourdough.

Use a probe thermometer:

  • Insert into the side of the loaf, not the bottom
  • Aim for the center
  • Read after 5 seconds

If it reads 195°F when you pull, the bread isn't done. Bake another 5–8 minutes.

A baked-but-doughy bake

Sometimes you do everything right — fermentation, bake, cool — and still get a slightly damp center. This usually means hydration was a touch high for your flour.

Drop water by 5% on the next bake. Most "doughy center" loaves clear up at one notch lower hydration.

When doughy is steam-related

Heavy steam baking can leave the center wet if you don't uncover long enough. Lift the lid earlier:

  • 18 minutes covered (not 25)
  • 25–28 minutes uncovered

The uncovered phase drives off interior moisture.

A diagnostic loaf

Test these variables one at a time:

Bake 1:

  • 75% hydration
  • 60% bulk rise
  • 200°F internal at 45 min total
  • Cool 3 hours before cutting

If this is fine: your previous bakes had one variable wrong.

Bake 2 (after success):

  • Same recipe but 78% hydration
  • Cool 3 hours

If still fine: your flour handles 78%. If wet: drop back to 75%.

This bracket method finds your flour's max hydration in two bakes.

Why bread is often "doughy" on day one but fine on day two

Some loaves taste damp when first cut and improve overnight as moisture redistributes through the crumb. If your loaf seems doughy hot but fine cold, your bake is closer to right than you think — just wait longer to cut.

Cool fully before storage

Storing a warm loaf in a bag traps steam, which migrates into the crumb. Warm loaf + bag = doughy.

Cool fully on a rack, then bag.

A final note on cutting

A serrated knife pulled in long, gentle strokes leaves a clean cut. A sawing motion drags the crumb and makes any borderline-wet bread look gummier than it is.

Try cutting your next loaf with a single long stroke and see if your "doughy" diagnosis still holds. Sometimes the bread is fine and the technique is the problem.
