Why Doesn't Bread Dough Rise?

Bread dough usually fails to rise because the yeast is dead or inactive, the dough is not kept in a warm enough place, or salt comes into direct contact with the yeast. The reason often comes down to yeast activity: if the yeast is inactive, the dough will not increase in volume no matter how long it sits. Yeast ferments sugars in the dough and produces carbon dioxide, which forms small bubbles and makes the dough expand. Water that is too hot or too cold can damage yeast cells or keep them from becoming active. Direct contact with salt can also harm yeast cells and slow fermentation.

What Should You Do to Help Bread Dough Rise?
Follow these steps to help the dough rise properly:
• Activate the yeast by letting it sit in warm water at 35–40 °C / 95–104 °F for a few minutes.
• Mix the salt into the flour so it does not come into direct contact with the yeast.
• After kneading, cover the dough and leave it in a warm, draft-free place.
• The first rise should generally take 1–1.5 hours.
• Leave the dough undisturbed until its volume has clearly increased.

What Mistakes Can Keep Dough from Rising?
Some common mistakes can prevent dough from rising. Expired or improperly stored yeast can prevent fermentation. Water that is too hot can damage yeast cells and make them inactive. A cold proofing environment slows fermentation. If the dough is not kneaded enough before proofing, the gluten may not be able to trap the gas.

Does the Type of Flour Affect How Dough Rises?
High-protein wheat flours, often called bread flour, form a stronger gluten network, which holds the gas produced by yeast more effectively and helps the dough rise more noticeably. Dough made with low-protein flour may hold less gas and rise less. Increasing the proportion of whole-grain flour can weaken the gluten network, so the dough may need a little more time to proof. Kneading time also affects the rise: if the dough is underkneaded, its gluten network may remain too weak to hold the gas. Knead until the dough is smooth and elastic. If it slowly springs back when pressed with a finger, it has been kneaded enough.

The size of the proofing bowl matters because you need to be able to monitor the dough's volume; use a bowl large enough to do so easily. Cover the dough with a damp cloth or plastic wrap to keep its surface from drying out and forming a crust. Turning on the light inside a closed oven is a practical way to create a warm, draft-free place for proofing.

Active, fresh yeast, the right temperature, and enough proofing time help bread dough rise to its expected volume. Checking that the yeast is fresh is an important first step. If you are unsure, let it sit in warm sugar water for a few minutes and check whether it foams before you start making the dough.
