Sourdough Too Chewy? How to Get a Tender Crumb

Overly chewy, rubbery sourdough is usually underfermented, overworked, or too low in hydration — not enough gas got trapped, so the crumb is tight and dense. A pleasant chew is good; a gummy, jaw-tiring chew means the dough needs more fermentation, more water, or gentler handling.

Good chew vs. bad chew

Cause 1: Underfermentation (most common)

A dough that didn't ferment enough has a tight, gummy crumb that eats heavy and chewy. Extend bulk fermentation until the dough has risen 50–75% and is jiggly and domed. Warm the kitchen if it's stalling.

Cause 2: Hydration too low

More water = a more open, tender crumb. If you're baking at 65% and finding it chewy, move to 70–72%.

Cause 3: Over-kneading (especially machines)

Over-developed gluten makes bread tough and chewy. With a stand mixer, stop as soon as the dough is smooth and passes the windowpane test. Hand methods rarely over-knead.

Cause 4: Too much bread flour / high protein

Very high-protein flour (14%+) makes chewier bread. For a softer crumb, blend in some all-purpose or a little whole wheat.

The tenderizing tricks

• Add a small amount of fat (olive oil, butter) — even 3–5% softens the crumb.
• A touch of milk or a small amount of honey/sugar also tenderizes.
• Full fermentation matters most: well-proofed bread is never rubbery.

Frequently asked questions

Why is my crumb chewy AND gummy?

That's underbaking plus underfermentation. Bake to 207–210°F internal and extend bulk.

Does cold fermentation make bread chewy?

No — it improves flavor and structure. Chewiness comes from proofing and hydration, not the fridge.

Is chewy bread underbaked?

Sometimes. Gummy-chewy is underbaked; dense-chewy is underfermented. Check internal temp to rule out the bake.

The line between perfect chew and rubbery is fermentation timing. SourdoughAI helps you nail the proof so the crumb comes out light.
