Known for its distinctive tangy flavor, chewy crust, and airy crumb, San Francisco sourdough is often regarded as the benchmark for sourdough lovers. In this guide, we will take you through the step-by-step process of making authentic San Francisco sourdough bread at home. From crafting your own starter to achieving that perfect crust, this comprehensive article will equip you with everything you need to know.
Understanding the Science of Sourdough
Before diving into the recipe, it’s important to understand what sets San Francisco sourdough apart. The unique flavor profile and texture of this bread are the results of a fermentation process driven by wild yeast and lactic acid bacteria present in the sourdough starter.
What is Sourdough Starter?
A sourdough starter is a mixture of flour and water that captures wild yeast from the environment. This process is called natural fermentation. Unlike commercial yeast, which provides rapid fermentation and consistency, a sourdough starter develops flavor over time.
The Role of the Environment
San Francisco’s unique climate, characterized by its cool fog and coastal breeze, plays a crucial role in developing the sourdough starter. The wild yeast and bacteria thrive in this environment, lending a characteristic tang to the bread. While you may not live in San Francisco, you can still replicate a similar starter in your own kitchen.
Creating Your Sourdough Starter
To get started on your sourdough bread-making journey, you’ll need a healthy, active sourdough starter. Here’s how you can create your own from scratch.
Ingredients for Sourdough Starter
- 100 grams of all-purpose flour or whole wheat flour
- 100 grams of water (preferably filtered or distilled)
Step-by-Step Guide to Making Sourdough Starter
Day 1: In a clean glass jar, mix 100 grams of flour with 100 grams of water. Stir until smooth, cover loosely with a cloth or lid, and let it sit at room temperature (ideally between 68°F to 75°F) for 24 hours.
Day 2 to 7: Discard half of the mixture and add 100 grams of water and 100 grams of flour each day. Stir well and cover again. You should start to see bubbles forming within a few days.
Day 7: By this point, your starter should be bubbly and have a pleasant sour smell. It’s now ready for baking! If it’s not as active, continue the feeding process for a few more days.

Now that your sourdough starter is ready, let’s gather the ingredients for the bread itself.
- 500 grams of bread flour
- 350 grams of water (room temperature)
- 100 grams of active sourdough starter
- 10 grams of salt
Making the Bread: Step-by-Step Instructions
Follow these steps to create your own hearty and flavorful San Francisco sourdough bread.
Step 1: Mixing the Dough
- In a large bowl, combine the flour and salt.
- In a separate bowl, mix the active sourdough starter with the water, stirring gently until it’s well combined.
- Pour the wet mixture into the dry ingredients and mix until there is no dry flour left. The dough will be shaggy and sticky.
Step 2: Autolyse
Let the dough rest for 1 hour. This process is called autolyse and it helps improve the dough’s structure as the flour absorbs water.
Step 3: Kneading
After the rest, knead the dough in the bowl or on a lightly floured surface. You can also use the stretch and fold technique:
- Stretch one side of the dough upward and fold it over itself.
- Rotate, and repeat this for all four sides.
- Continue this process for about 5-10 minutes until the dough becomes smooth and elastic.
Step 4: Bulk Fermentation
Place the dough in a lightly greased bowl and cover it with a clean cloth or plastic wrap. Let it rise at room temperature for about 4 hours. During this time, perform the stretch and fold technique every 30 minutes for the first 2 hours.
Step 5: Shaping the Dough
After the bulk fermentation, turn the dough out onto a lightly floured surface. Shape the dough into a round or oval loaf, depending on your preference.
- Gently flatten the dough and fold the edges toward the center.
- Flip the dough seam-side down and use your hands to create tension by gently pulling the dough toward you.
Step 6: Proofing
Place the shaped dough into a proofing basket or a bowl lined with a floured kitchen towel. Cover it with a cloth and allow it to proof for another 2-4 hours at room temperature, or overnight in the refrigerator. This long proofing process enhances flavor and structure.
Step 7: Preheating the Oven
About 30 minutes before baking, preheat your oven to 450°F (232°C). If you have a dutch oven, place it inside the oven to preheat as well. This will create the steam needed for a perfect crust.
Step 8: Scoring and Baking
Once your dough has risen, carefully turn it out onto a piece of parchment paper. Using a sharp razor or bread lame, score the top of the loaf with a pattern of your choice. This allows the bread to expand while baking.
- Carefully place the dough into the preheated Dutch oven (you can remove the lid).
- Cover with the lid and bake for 30 minutes.
- Remove the lid and bake for an additional 15-20 minutes until the crust is a deep golden brown.
Step 9: Cooling
When fully baked, carefully remove the bread from the oven and transfer it to a wire rack. Allow the bread to cool for at least one hour before slicing. This step is crucial, as it allows the interior to set and enhances the flavor.
Tips for Perfecting Your Sourdough Bread
- Hydration Levels: Experiment with different hydration levels for varying textures. A higher hydration dough can lead to a more open crumb structure.
- Temperature: Consistency is key. Keep your kitchen environment stable for optimal fermentation.
- Tasting the Starter: Regularly taste your starter to ensure it’s developing the desired sourness.
- Timing: Don’t rush through the proofing stages. Allowing enough time improves flavor complexity.
Storage Suggestions
Proper storage is key to maintaining the freshness of your sourdough bread.
At Room Temperature
Store your sourdough bread in a paper bag or a bread box. Avoid plastic bags, as they can trap moisture and lead to a soggy crust.
Freezing
For long-term storage, slice the bread and freeze the pieces in an airtight container. To enjoy, simply toast or let thaw at room temperature.

What makes San Francisco sourdough bread unique?
San Francisco sourdough bread is unique primarily due to its distinctive flavor and chewy crust. This is primarily a result of the specific strains of wild yeast and bacteria that thrive in the San Francisco climate. These microorganisms contribute to the bread’s characteristic tanginess, which is a delightful balance to the bread’s rich, complex flavor.
Another factor contributing to its uniqueness is the method of fermentation. The traditional sourdough process involves a long, slow fermentation period. This not only develops flavor but also improves the bread’s texture and shelf life. The cold fermentation process allows the dough to rise slowly, resulting in a bread that is both flavorful and resilient.
What ingredients are essential for making authentic San Francisco sourdough?
The essential ingredients for making authentic San Francisco sourdough bread include high-protein bread flour, water, salt, and a sourdough starter. The flour provides the necessary gluten structure, which is crucial for giving the bread its chewy texture. It’s important to use a high-quality bread flour that has a protein content of around 12-14%.
Salt is another key ingredient, not only for flavor but also for controlling the fermentation process. The sourdough starter, which is a mixture of flour and water that has been fermented with wild yeast and bacteria, is what sets sourdough apart from other types of bread. This starter can be cultivated over time from the local environment or obtained from established bakers to ensure authenticity.
How do I create a sourdough starter at home?
Creating a sourdough starter at home is a straightforward process that requires only flour, water, and patience. Start by mixing equal parts of flour and water in a jar to form a thick paste. It’s best to use whole grain flour initially, as it contains more nutrients to nourish the wild yeast. Leave the mixture at room temperature, and feed it with fresh flour and water every 24 hours.
After about a week, you should start to see bubbles forming, indicating that wild yeast is developing in your starter. It’s important to keep feeding the starter to maintain its activity. As it matures, it will become more robust and will be ready to use in baking, providing the unique flavor and leavening needed for authentic sourdough bread.
How long does it take to bake sourdough bread from start to finish?
The total process of making sourdough bread can take anywhere from 12 to 24 hours, depending on the method and recipe used. Initially, you’ll need to prepare your dough, which can take about 1 to 2 hours, including mixing and kneading. Once the dough is formed, it must undergo a long fermentation period, ranging from 8 to 12 hours, or even longer if you opt for a cold fermentation in the refrigerator.
After the fermentation, you’ll shape the dough, and it will need another rise or proofing period of 1 to 2 hours. Finally, the bread is baked, typically for about 30 to 45 minutes. While the active work time might be relatively short, the overall timeline is extended due to the several fermentation stages crucial to developing the bread’s signature flavor and texture.
Can I use all-purpose flour instead of bread flour?
While you can use all-purpose flour to make sourdough bread, bread flour is highly recommended for the best results. Bread flour has a higher protein content, which develops more gluten structure during kneading. This results in a chewier texture and a better rise, both essential characteristics of good sourdough bread.
If you choose to use all-purpose flour, you may find the bread to be softer and less chewy than traditional sourdoughs. However, you can still achieve a decent loaf by adjusting the hydration level in your recipe since all-purpose flour absorbs water differently. For a more authentic texture, consider blending all-purpose flour with bread flour or focusing on high-protein all-purpose varieties.
What should I do if my sourdough doesn’t rise?
If your sourdough bread isn’t rising, it could be due to several factors. One common issue is the activity level of your sourdough starter. Ensure that your starter is bubbly and has doubled in size within a reasonable time frame after feeding. If it’s sluggish, it may need more frequent feedings or warmer temperatures to activate the wild yeast and bacteria.
Other factors could include the temperature of your environment or the dough hydration. Bread dough requires warmth to rise effectively, usually around 75-85°F (24-29°C). If your kitchen is cool, consider placing the dough in a slightly warmer area or using an oven with the light on as a proofing box. Adjust and experiment to achieve optimal rising conditions, as each environment may differ.
How can I achieve a crispy crust on my sourdough bread?
To achieve a crispy crust on your sourdough bread, steam is key during the initial baking phase. When you place your dough in the oven, you can create steam by placing a pan filled with water at the bottom of the oven or by spraying the dough with water right before baking. This moisture helps form a glossy, hard crust as the bread bakes.
Another tip for enhancing crustiness is to bake your bread inside a preheated Dutch oven. The closed environment retains moisture, which contributes to the initial steaming effect. Once the bread has baked for about 20-30 minutes or has achieved a golden brown color, you can remove the lid to allow the crust to develop further and become crispy.
How should I store my sourdough bread to keep it fresh?
To keep your sourdough bread fresh, it’s best to store it at room temperature in a paper bag or a linen cloth. Avoid plastic bags, as they trap moisture and can lead to a soggy crust. Keeping the bread in a breathable material will help maintain the crust’s texture while preventing it from drying out.
If you want to store the bread for a longer period, consider freezing it. Slice the loaf before freezing so you can easily take out only what you need. Wrap the slices in plastic wrap or foil, and place them in an airtight bag. To enjoy your frozen sourdough, simply toast or reheat the slices, and they will taste nearly as fresh as when they were first baked.
