When it comes to baking bread, every step in the process plays a crucial role in the final outcome. From selecting the finest ingredients to mastering the art of kneading and proofing, each factor contributes to the success or failure of your bread. One often overlooked yet essential element when it comes to proofing is room temperature.

In this article, we’ll delve into what is considered room temperature for bread making and why it is essential for achieving the perfect loaf.

Understanding Room Temperature:

In the context of bread making, room temperature refers to the ambient temperature at which the dough will sit during any resting or proofing stages. Warmth is required for the yeast to thrive and produce carbon dioxide gas.

The key benefit of gas creation is making the dough rise, resulting in a light and airy crumb texture.

When following bread recipes at home, the expected room temperature falls between 70°F (21°C) and 78°F (25°C). However, this range varies depending on the specific recipe, ingredients, and desired results.

How to determine your room temperature

To find the room temperature of your baking environment, all you need to do is grab a thermometer and place it in the room for 5 minutes to adjust to the room’s temperature. Once the temperature reading is stable, take note of the reading, this is your room temperature.

Use a thermometer to take a temperature reading.

I always use a temperature probe when baking, but any thermometer can be used to find the temperature of a room. Place the thermometer away from direct sunlight, drafts, or any other factors that may influence the reading.

The Importance of Room Temperature:

Room temperature during the bread-making process is crucial for several reasons:

Dough temperature

The temperature of the dough after mixing is important. If the dough is too cold, it takes a long time to rise. Yet if the dough is too warm, the yeast becomes overly active and produces excessive amounts of gas early on, making the dough gassy and hard to shape. A warm dough leads to a weaker rise as the sugars in the flour are consumed, and the yeast is unable to create enough gas during the later parts of proofing.

The dough temperature depends on the temperature of the room, the flour and the water. Professional bakers take readings of the room and flour. These temperatures are inputted into a formula to provide the optimum water temperature. The water temperature is then adjusted so the desired dough temperature is reached.

Yeast Activation

Yeast, a microorganism responsible for fermentation, is a key player in bread making. It needs warmth to activate and multiply rapidly, allowing it to convert sugars into carbon dioxide and alcohol. Optimum room temperature ensures optimal yeast activity, producing a well-risen dough.

If the room is warmer than 78F (25C), the dough temperature must be lowered further to slow down the rising process.

Enzymatic Activity

Room temperature affects the enzymatic activity in the dough. Enzymes present in the flour and yeast break down complex carbohydrates into simpler sugars, providing food for the yeast. This process aids in flavour development and contributes to the overall quality of the bread.

Dough Consistency

Different temperatures can impact the consistency of the dough. A warmer room temperature speeds up fermentation, shortening the resting stage (bulk fermentation). As gluten matures during bulk fermentation, shortening it leads to a weaker gluten structure. To compensate, the dough must be kneaded for longer to ensure the dough structure is robust enough to capture gas efficiently.

Flavour Development

Fermentation at the right room temperature allows for the formation of flavorful compounds. A longer fermentation time at a moderate temperature permits the development of complex flavours, creating a more aromatic and delicious bread.

Maintaining Room Temperature

Achieving and maintaining the ideal room temperature for bread making requires a few considerations:

Seasonal variations

Room temperatures naturally fluctuate with the changing seasons. During colder months, finding ways to warm up the environment might be necessary, such as placing the dough near a warm spot or using a DIY proofing box or oven with a proofing function. In warmer months, you may need to keep the dough in a cooler spot or adjust the fermentation time to avoid over-proofing.

Adjusting for climate variations

When following a recipe written in a country with a different climate to yours, room temperature is likely to be different. If their temperature is likely to be warmer, you should expect your dough to take longer to bulk ferment or rise.

If your room temperature falls outside the ideal range, you can adjust the fermentation time accordingly. Warmer temperatures accelerate the rate at which yeast cells respire or ferment. Cooler temperatures slow it down. 

Adjust the water temperature by adding hot or cold water

To compensate for a cool room temperature, you can warm your dough by using warmer water or a proofing box. Alternatively, slightly reduce the kneading time and accept that the dough will take longer to rise.

Keep a close eye on the dough’s volume and texture to determine when it is ready for the next step.


Achieving the perfect room temperature for bread making is an essential aspect of the baking process. From activating yeast to promoting enzymatic activity and flavour development, room temperature plays a vital role in producing high-quality bread.

Bakers can ensure consistent and satisfying results by understanding the impact of temperature and making necessary adjustments. So, next time you embark on a bread-making adventure, pay attention to the room temperature and let it work its magic on your dough.
