Common Sourdough Mistakes and How to Fix Them

Sourdough baking is a rewarding yet sometimes frustrating journey. If you’ve ever ended up with dense loaves, weak starters, or gummy interiors, you’re not alone! Here’s a troubleshooting guide to help you fix the most common sourdough mistakes and improve your bread baking skills.

1. Weak or Inactive Starter

Problem: Your sourdough starter isn’t bubbling, rising, or developing a strong aroma.

Fix:

  • Feed your starter with equal parts flour and water by weight.
  • Use unbleached flour, as bleaching agents can weaken fermentation.
  • Keep it in a warm place (75-80°F) to encourage yeast activity.
  • Feed it regularly, at least once daily, or twice if very weak.
  • If neglected, refresh it with multiple feedings over a few days.

2. Dense or Heavy Bread

Problem: Your sourdough loaf comes out too dense and lacks an open crumb.

Fix:

  • Ensure your starter is active before baking (it should double within 4-6 hours of feeding).
  • Allow enough bulk fermentation time; under-fermentation leads to a dense loaf.
  • Use proper folding techniques to build strength in the dough.
  • Consider increasing hydration if the dough is too stiff.
  • Make sure you’re shaping the dough tightly to create good structure.

3. Gummy or Underbaked Bread

Problem: The interior of your bread is sticky, gummy, or seems wet even after baking.

Fix:

  • Extend the baking time; an underbaked loaf will be gummy inside.
  • Ensure the oven temperature is accurate using an oven thermometer.
  • Let the loaf cool completely before slicing. Sourdough continues to set as it cools.
  • Make sure the dough is fully proofed before baking.

4. Overproofed Dough

Problem: Your dough is too slack, spreads out instead of rising, or collapses in the oven.

Fix:

  • Reduce proofing time, especially in warm conditions.
  • Use the “poke test”: gently press a floured finger into the dough. If the indentation stays, it’s overproofed.
  • If slightly overproofed, try refrigerating it for an hour before baking to firm up the dough.
  • Next time, watch for dough doubling in size rather than relying on time alone.

5. Lack of Oven Spring

Problem: Your loaf doesn’t rise well in the oven and stays flat.

Fix:

  • Ensure proper gluten development through sufficient kneading or stretch-and-folds.
  • Use steam in the oven (by adding a pan of hot water or baking in a Dutch oven) to allow for better rise.
  • Score the dough with a sharp blade to guide expansion.
  • Bake at a high initial temperature (450°F) for the first 15 minutes to encourage oven spring.

6. Too Sour or Not Sour Enough

Problem: Your bread is either too tangy or lacks the sour flavor you expect.

Fix:

  • For more sour bread, use a stiff starter, cold-proof for longer (12-24 hours), and extend bulk fermentation.
  • For less sour bread, feed the starter more frequently, use a shorter proofing time, and avoid extended refrigeration.

7. Hard or Thick Crust

Problem: Your crust is too thick or hard to chew.

Fix:

  • Add steam during baking to keep the crust from setting too fast.
  • Bake at a slightly lower temperature if your oven runs hot.
  • Brush the crust with butter after baking for a softer texture.
  • If storing, wrap in a towel instead of plastic to prevent excessive hardening.

8. Sticky Dough That’s Hard to Handle

Problem: The dough is too wet and difficult to shape.

Fix:

  • Use a light dusting of flour or wet hands when handling.
  • Allow the dough to rest between stretch-and-folds to develop strength.
  • Refrigerate for 30 minutes before shaping to make handling easier.
  • Reduce hydration slightly if struggling with very wet dough.

9. Burnt Bottom Crust

Problem: The bottom of your bread is too dark or burnt.

Fix:

  • Place a baking sheet or pizza stone on a lower rack to diffuse direct heat.
  • Use parchment paper or bake on a different surface.
  • If baking in a Dutch oven, elevate the loaf with a piece of parchment or a trivet.

10. Inconsistent Results

Problem: Sometimes your sourdough turns out great, and other times it flops.

Fix:

  • Keep a baking journal to track variables like temperature, hydration, proofing time, and flour type.
  • Use the same flour brands and water source for consistency.
  • Adjust based on seasonal changes—dough ferments faster in warm weather.
  • Be patient; experience improves consistency over time!

Final Thoughts

Sourdough baking takes practice, but every “failed” loaf is a learning experience. By troubleshooting these common mistakes, you’ll refine your technique and get closer to achieving bakery-quality sourdough at home. Keep experimenting, stay patient, and enjoy the process!
