Troubleshooting Your First Sourdough Bake

Your first sourdough won't be perfect. Most aren't. Here are the specific problems beginners face, and what to fix.

Loaf is flat and dense

Most likely — under-fermented bulk. Your dough didn't rise enough during the bulk phase.

Less likely — weak starter, room too cold, hydration too low.

Fix — Next time, watch for the dough to rise 50–70% during bulk. If your kitchen is cool, allow more time. Verify your starter is doubling within 4–8 hours of feeding before using it.

Loaf is flat but the crumb is open

Most likely — over-fermented bulk. The dough rose, then collapsed before baking.

Fix — Next time, shorten bulk by 30–60 minutes. Bake when the dough is springy and risen 50–70%, not when it's at maximum puff.

Crust is pale, almost white

Most likely — oven not hot enough, or didn't preheat long enough.

Fix — Verify oven temperature with a thermometer (most home ovens lie). Preheat 45 minutes minimum with the Dutch oven inside. Bake at 500°F for the first phase.

Crust is gold but bland-tasting

Most likely — under-baked. The Maillard browning didn't fully develop.

Fix — Bake longer. Push the color past gold to deep amber or mahogany. Internal temperature 207°F minimum.

Interior is wet and gummy

Most likely — under-baked. Verify with a thermometer.

Fix — Bake longer. If your loaf is browning too fast, reduce temperature 25°F and continue baking.

Also possible — cut too early. Wait 90 minutes minimum after pulling from oven.

Crust is hard like a rock

Most likely — over-baked, or under-steamed.

Fix — Use a Dutch oven for steam. Don't bake past internal temperature 215°F. Pull when deep mahogany, not when black.

Bread tastes "off"

Most likely — over-fermented. Excess acid produces unpleasant flavors.

Fix — Shorter bulk. Cooler bulk environment. Less starter percentage.

Bread tastes like nothing

Most likely — under-fermented. Fermentation produces flavor; no fermentation, no flavor.

Fix — Longer bulk. Try a long cold proof (12+ hours).

Score didn't open

Most likely — dull blade, or scoring too shallow.

Fix — Sharp blade (replace if used many times). Score ¼ inch deep at a 30° angle.

Also possible — over-proofed dough doesn't have enough spring to open at the score.

Score opened but crust looks ragged

Most likely — dull blade dragging, or hesitant cut.

Fix — Use a sharp blade. Make the cut in one confident movement.

Stuck in the banneton

Most likely — not enough flour in the basket.

Fix — Generously dust the banneton with rice flour (works better than wheat flour). Use a liner cloth for problem doughs.

Uneven shape — leans to one side

Most likely — uneven shaping.

Fix — Build tension evenly all around the dough. Drag the boule across the counter with your bench scraper to balance tension.

Top of loaf is misshapen

Most likely — the dough collapsed during transfer to the oven.

Fix — Use parchment paper as a sling. Lower gently into the Dutch oven. Don't drop.

Loaf is asymmetric (a "duck") — one side higher than the other

Most likely — uneven scoring depth, or uneven shaping.

Fix — Score with consistent depth across the loaf. Build symmetric tension during shaping.

Crumb has a giant hole under the top crust

Most likely — under-shaped (didn't seal the bottom seam) or under-mixed (uneven gluten).

Fix — Pinch the bottom seam closed during shaping. Mix until uniform.

Some big holes, some small holes, in random places

Most likely — uneven incorporation of starter.

Fix — Mix starter and water thoroughly before adding flour. Stretch and fold uniformly during bulk.

Bread sat in the oven and didn't spring at all

Most likely — over-proofed (no spring left), or oven not hot enough.

Fix — Reduce final proof. Verify oven temperature. Use boiling water in a steam pan if you don't have a Dutch oven.

Doesn't taste sour

Most likely — short fermentation. Sour flavor develops with time.

Fix — Long cold proof (24+ hours). Cooler bulk temperature. Stiff starter.

Tastes too sour

Most likely — over-fermented or starter is too acidic from neglect.

Fix — Shorter fermentation. Refresh your starter with several feedings. Warmer bulk temperature.

The most common first-bake mistake

Cutting too early.

If your bread looks great but feels gummy or wet inside, you may have just cut too early. Wait the full 90 minutes minimum, even for a small loaf.

What's normal

A first sourdough that's:

• Slightly dense
• Pale-ish crust
• Less open than the photos
• Still taste like real bread

...is a normal first sourdough. Bake it again. Adjust one variable. By bake 5, you'll see real progress.

What to focus on

Don't try to fix everything at once. Pick the biggest problem from your last bake and adjust one variable.

Bake 1 — too dense → longer bulk, then bake again Bake 2 — better but pale → hotter oven, longer bake Bake 3 — better but bland → longer cold proof Bake 4 — better but uneven → focus on shaping technique Bake 5 — much better → keep iterating

This is how every baker improves. One variable at a time.
