Why your bread doesn't rise

Too much flour

Extra flour can make dough stiff. Before adding flour during kneading, check the specified amount and whether the dough is meant to be sticky.

Our bread-flour reference gives 4 cups × 120 g = 480 g. A recipe’s own gram weight takes priority; avoid adding flour solely to make the dough stop sticking.

Dead or expired yeast

Old or poorly stored yeast may be ineffective. Follow the yeast package’s instructions for mixing and liquid temperature; different yeast products use different methods.

If the manufacturer recommends an activity test, follow that method. Instant yeast usually goes directly into the flour; a separate foaming test is not a required step for every loaf.

Salt and yeast: check the amount

Salt slows fermentation, but brief contact with yeast during normal mixing does not kill it. Check the amount of salt rather than blaming contact between the two ingredients.

The dough was too cold

Cold dough rises more slowly. Use the recipe’s temperature guidance and judge expansion as well as elapsed time; check any improvised warm proofing spot with a thermometer.

Not enough gluten development

Gluten — the protein network in wheat flour — is what traps the gas bubbles that make bread light. If the dough is not kneaded enough, or if a low-protein flour was used, the gluten network is too weak to hold the bubbles and the bread collapses.

Use the flour specified in the recipe. A different protein content or whole-grain proportion can change water absorption and dough handling.

Quick breads: different leavening, same measurement issue

Quick breads (banana bread, muffins, soda bread) use baking soda or baking powder instead of yeast. These are also susceptible to measurement errors — too little leavening and the bread stays dense, too much and it rises fast and then collapses.
