Sourdough baking is an ancient art that requires patience, persistence, and a deep understanding of the intricacies involved in working with wild yeast. One of the most common challenges faced by both novice and experienced bakers is the issue of sourdough loaves flattening, which can be disappointing and frustrating. However, with the right techniques and a bit of practice, it’s possible to overcome this issue and produce beautiful, well-structured loaves that are sure to impress. In this article, we’ll delve into the world of sourdough baking and explore the reasons behind flattening, as well as provide valuable tips and strategies for preventing it.
Understanding Sourdough and the Causes of Flattening
Before we dive into the solutions, it’s essential to understand the basics of sourdough baking and the factors that contribute to flattening. Sourdough is a type of bread that uses a natural starter culture instead of commercial yeast, which gives it a unique flavor and texture. The starter culture is a mixture of wild yeast and bacteria that ferments the sugars in the dough, producing carbon dioxide gas and creating the bubbles that give sourdough its characteristic texture.
The Role of Yeast and Gluten in Sourdough
Yeast plays a crucial role in the sourdough baking process, as it’s responsible for fermenting the sugars and producing the carbon dioxide that makes the dough rise. However, yeast is not the only factor at play – gluten is also a critical component of sourdough. Gluten is a protein found in wheat flour that gives dough its elasticity and structure, allowing it to hold its shape and rise. Weak gluten structure is one of the primary causes of flattening in sourdough loaves, as it can’t support the weight of the dough and allow it to hold its shape.
Other Factors That Contribute to Flattening
In addition to weak gluten structure, there are several other factors that can contribute to flattening in sourdough loaves. These include overproofing, which occurs when the dough is allowed to rise for too long and the yeast ferments all the available sugars, causing the dough to collapse. Overmixing is another common culprit, as it can damage the gluten structure and lead to a dense, flat loaf. Incorrect temperature and humidity levels can also affect the baking process, as yeast is sensitive to temperature and humidity and can be slowed down or speeded up by changes in these conditions.
Techniques for Preventing Flattening in Sourdough
Now that we’ve explored the causes of flattening, let’s move on to the solutions. There are several techniques that can help prevent flattening in sourdough loaves, including:
Developing a Strong Gluten Structure
Developing a strong gluten structure is critical for creating a well-structured sourdough loaf. This can be achieved through a process called stretching and folding, which involves gently stretching and folding the dough to develop the gluten. This process should be done gently and carefully, as overmixing can damage the gluten structure and lead to a dense, flat loaf.
Monitoring Proofing Time
Monitoring proofing time is another essential technique for preventing flattening. Proofing is the process of allowing the dough to rise, and it’s critical to monitor the time and temperature to ensure that the dough doesn’t overproof. Overproofing can cause the yeast to ferment all the available sugars, leading to a collapse of the dough and a flat loaf.
Controlling Temperature and Humidity
Controlling temperature and humidity is also crucial for preventing flattening. Yeast is sensitive to temperature and humidity, and changes in these conditions can affect the baking process. A consistent temperature and humidity level can help to regulate the yeast’s activity and prevent overproofing or underproofing.
Creating a Sourdough Schedule
Creating a sourdough schedule can help to ensure that the baking process is well-planned and executed. This schedule should include the times for mixing, proofing, and baking, as well as any additional steps such as stretching and folding. By following a schedule, bakers can ensure that the dough is handled gently and carefully, and that the proofing time is monitored closely to prevent overproofing.
Additional Tips for Achieving Perfect Sourdough Loaves
In addition to the techniques mentioned above, there are several other tips that can help bakers achieve perfect sourdough loaves. These include:
- Using a high-protein flour that is rich in gluten, as this will help to create a strong gluten structure and prevent flattening.
- Keeping the dough at room temperature during the proofing process, as this will help to regulate the yeast’s activity and prevent overproofing.
By following these tips and techniques, bakers can create beautiful, well-structured sourdough loaves that are sure to impress. Remember, sourdough baking is an art that requires patience, persistence, and practice, so don’t be discouraged if it takes time to achieve the perfect loaf.

What causes sourdough bread to flatten during the baking process?
Sourdough bread can flatten during the baking process due to several reasons, including overproofing, insufficient gluten development, or excessive oven temperature. Overproofing occurs when the dough is allowed to rest for too long, causing the yeast to produce too much carbon dioxide, which can lead to a collapse of the bread’s structure. Insufficient gluten development, on the other hand, can result from inadequate mixing or underdeveloped dough, making it difficult for the bread to hold its shape. Excessive oven temperature can also cause the bread to flatten, as the rapid expansion of gases can cause the bread to spread out instead of rising upwards.
To prevent flattening, it is essential to monitor the proofing time and adjust it according to the recipe and environmental conditions. Additionally, ensuring proper gluten development through adequate mixing and kneading can help the bread maintain its structure. Using a steamy oven environment can also help to create a more even crumb and prevent the bread from spreading out too much. By controlling these factors and making adjustments as needed, bakers can minimize the risk of flattening and produce perfectly shaped sourdough loaves. Regular practice and experimentation can also help bakers develop the necessary skills to predict and prevent flattening, leading to more consistent and desirable results.
How can I create a sourdough starter from scratch, and what are the benefits of doing so?
Creating a sourdough starter from scratch involves mixing flour and water to create a natural fermentation process that attracts wild yeast and bacteria. To create a starter, simply combine equal parts of flour and water in a clean container, cover it, and let it rest in a warm, draft-free environment. Over time, the mixture will begin to bubble and emit a sour smell, indicating that the fermentation process has started. This process can take anywhere from several days to a week or more, depending on factors such as temperature, humidity, and the type of flour used. The benefits of creating a sourdough starter from scratch include having complete control over the ingredients and the fermentation process, as well as the potential for creating a unique flavor profile that reflects the local environment.
