There’s something irresistibly charming about the golden crust, tangy flavor, and chewy texture of San Francisco sourdough bread. This artisanal delight has been a beloved staple of American baking for generations, characterized by its distinctively crisp crust and soft, airy interior. If you’ve ever wanted to create this iconic bread in your own kitchen, you’ve come to the right place. Below, we’ll explore the entire process of making authentic San Francisco sourdough bread—from crafting your starter to perfecting the baking technique.
Understanding Sourdough: A Fermented Tradition
Sourdough bread is a type of bread that rises through the natural fermentation process, relying on wild yeasts and lactic acid bacteria present in the environment. Unlike commercial yeast-based breads, which rise quickly, sourdough requires a more extended fermentation period, allowing flavors to develop deeply. What makes San Francisco sourdough distinct is its unique combination of California’s coastal environment and the specific strains of yeast and bacteria that thrive in the area.
The Key Ingredients of San Francisco Sourdough Bread
To embark on your sourdough journey, you’ll need the following essential ingredients:
- Bread Flour: The backbone of your loaf. Choose high-quality bread flour for its higher protein content, which supports gluten development.
- Water: Filtered or bottled water is best to avoid chlorine and impurities that may hinder fermentation.
- Sourdough Starter: A mixture of flour and water that captures wild yeast and bacteria from the environment. It needs to be active and bubbly to leaven your bread properly.
- Salt: Enhances flavor and strengthens gluten structure.
Gathering Your Equipment
Before you dive into making sourdough bread, ensure you have the right tools at your disposal:
- Baking stone or Dutch oven
- Mixing bowl
- Dough scraper
- Kitchen scale (for precise measurements)
- Proofing basket or bowl
- Sharp knife or lame (for scoring)
Creating Your Own Sourdough Starter
If you don’t already have a sourdough starter, you’ll need to create one. Although it takes time, the process is simple and rewarding.
Ingredients for Sourdough Starter
To begin your starter, you’ll need:
- Whole wheat flour (or rye flour for a richer flavor)
- Water
Steps to Create Your Sourdough Starter
-
Day 1: In a clean glass jar, mix 100 grams of whole wheat flour with 100 grams of water. Stir until fully combined, and cover loosely with a lid or plastic wrap. Allow it to rest at room temperature for 24 hours.
-
Day 2-7: Each day, check for bubbles, which indicate fermentation. Feed the starter by discarding half of the mixture and adding 100 grams of all-purpose flour and 100 grams of water. Stir and cover loosely again. By Day 7, you should have a bubbly, active starter with a pleasant, tangy scent.
Maintaining Your Starter
To keep your starter healthy, continue feeding it on a regular schedule—ideally every 24 hours at room temperature or once a week if you store it in the fridge. You will need at least 100 grams of active starter for your bread.
Making San Francisco Sourdough Bread
Now that you have your starter ready, let’s move on to the bread-making process.
Ingredients for San Francisco Sourdough Bread
Once your starter is active, gather the ingredients for the bread:
- 500 grams of bread flour
- 350 grams of water (divided into 300g for mixing and 50g for adjustments)
- 150 grams of active sourdough starter
- 10 grams of salt
Step-by-Step Process
- Mixing the Dough:
-
In a large mixing bowl, combine the bread flour and 300 grams of water. Stir until no dry flour remains. Autolyse (rest) for 30 minutes. This process allows the flour to fully hydrate and gluten to develop.
-
Incorporating Starter and Salt:
-
After autolyse, add your 150 grams of active sourdough starter and 10 grams of salt. Mix thoroughly, using your hands to break up the starter and evenly distribute it throughout the dough.
-
Bulk Fermentation:
-
Cover the bowl with a damp cloth and let it rise at room temperature for about 4-6 hours. Every 30 minutes, perform a series of stretch and folds—gently pull one edge of the dough and fold it over itself, rotating the bowl 90 degrees after each fold (total of 4 folds each time).
-
Pre-shaping:
-
Once the dough has roughly doubled in size, turn it out onto a lightly floured surface. Gently shape it into a round ball using a bench scraper. Let it rest for 20-30 minutes, covered with a cloth.
-
Final Shape:
-
After resting, flip the dough over so that the seam is facing up. Shape it into its final form (batard or round), ensuring to create surface tension by pulling the dough toward you while shaping.
-
Proofing:
- Transfer your shaped dough to a proofing basket, seam side up. Cover it with a cloth and let it proof for about 2-4 hours at room temperature or overnight in the refrigerator for a cold-proofing method.
Baking Your Sourdough Bread
Once your dough has finished proofing, it’s time to bake. Preheating your oven is critical for achieving that perfect crust.
Preheat the Oven
- Preheat your oven to 450°F (232°C) for at least 30 minutes before baking. If you’re using a Dutch oven, place it inside the oven to preheat as well.
Scoring Your Bread
- When ready to bake, carefully flip your dough out onto a piece of parchment paper, seam side down. Use a sharp knife or lame to score the top of the dough—this allows the bread to expand during baking.
Baking Process
- Baking in a Dutch Oven:
-
Carefully remove the hot Dutch oven from the oven (handle with oven mitts). Lift the parchment with the dough and lower it into the pot. Cover with the lid and bake for 30 minutes. After 30 minutes, remove the lid and bake for an additional 15-25 minutes or until golden brown.
-
Baking on a Baking Stone:
- Alternatively, place the dough directly on the baking stone and create steam in the oven by placing a few ice cubes in a cast-iron skillet on the lower rack. Bake for approximately 30-40 minutes, rotating halfway through for even browning.
Cooling the Bread
- Once baked, transfer your bread to a wire rack and allow it to cool completely (at least one hour) before slicing. This cooling process helps the crumb set and enhances the flavor.
Storing Your Sourdough Bread
To preserve the freshness of your San Francisco sourdough bread, store it in a paper bag at room temperature for up to 3 days. For longer storage, slice and freeze the loaf, allowing individual slices to be toasted as needed.

Making San Francisco sourdough bread is a labor of love, but the reward is exceptionally satisfying. With practice, your skills will develop, enabling you to enjoy one of the most iconic breads right in your home. So, grab your baking tools and starter, and immerse yourself in the delectable world of sourdough. Not only will you be creating a scrumptious, crusty loaf, but you’ll also be embracing a rich tradition—one that dates back centuries in San Francisco and beyond. Happy baking!
What is San Francisco sourdough bread?
San Francisco sourdough bread is a distinct style of sourdough known for its robust flavor and chewy crust. It is characterized by its tangy taste, which is a result of the unique wild yeast and bacteria found in the San Francisco area. The local climate, with its foggy mornings and temperate conditions, creates an ideal environment for cultivating the sourdough starter that gives this bread its signature flavor profile.
The bread is made using a long fermentation process that enhances its complexity and chewiness. Traditional French baguettes and other bread types are typically leavened with commercial yeast, while San Francisco sourdough relies on natural leavening, which results in its distinct tanginess and texture.
How do I start a sourdough starter?
Starting a sourdough starter is a simple yet rewarding process that involves mixing flour and water to create a living culture of wild yeast and bacteria. You’ll begin with equal parts by weight of flour and water, typically around 100 grams each. Mix the ingredients in a clean jar, cover it loosely with a cloth, and allow it to sit at room temperature. This initial mixture will begin to develop over the next few days.
After a few days, you should see bubbles forming on the surface, indicating that fermentation is taking place. At this stage, start feeding your starter once a day by discarding half and adding fresh flour and water in equal parts. Continue this process for about one week until your starter is bubbly and has a pleasant sour aroma, which indicates that it is ready for baking.
Why is my sourdough bread dense?
A dense loaf of sourdough bread can be the result of several factors, primarily related to hydration, starter activity, and fermentation time. If your dough has a low hydration level, it can lead to denser bread, as the gluten may not develop sufficiently. Increasing the water content or adjusting your flour type to include high-protein bread flour may improve the dough’s elasticity.
Another reason for density could be insufficient fermentation. If your starter is not active enough or the dough hasn’t risen adequately during bulk fermentation, the resulting loaf will lack the airiness that characterizes good sourdough. Ensuring your starter is bubbly and well-fed before use, as well as allowing enough time for the bulk fermentation phase, will yield a lighter and more open crumb structure.
How do I achieve the perfect crust on sourdough bread?
Achieving the perfect crust on your sourdough bread involves a combination of steam and the right baking temperature. When baking, it’s crucial to create steam in the oven during the first part of the baking process, as this helps the dough expand and creates a crispy crust. You can do this by placing a pan of water in the oven or by spritzing the bread with water before closing the oven door.
Additionally, using a Dutch oven can help trap steam around the bread, promoting an ideal crust. Preheating your Dutch oven and baking at a higher temperature, like 450°F (232°C), will also yield a beautifully crusty exterior while ensuring the inside is fully cooked. Following this technique will give your sourdough that coveted golden-brown color and textural contrast.
How long does sourdough bread take to rise?
The rising time for sourdough bread can vary widely depending on several factors, including the temperature of your kitchen, the strength of your starter, and the hydration level of your dough. Generally, you can expect the initial bulk fermentation to take anywhere from 4 to 8 hours, with a second rise (or proof) lasting about 1 to 4 hours. Warmer environments typically lead to faster fermentation, while cooler temperatures will slow it down.
To determine if your dough has risen enough, you can perform the “poke test.” Gently poke the surface of the dough; if it springs back slowly and retains a slight indentation, it is ready for shaping or baking. Monitoring your dough’s rise is crucial, as under-proofing can lead to denser bread, while over-proofing might result in a collapse during baking.
What types of flour work best for San Francisco sourdough bread?
For San Francisco sourdough bread, using a high-quality bread flour is typically recommended, as it contains more protein than all-purpose flour. The additional protein aids gluten development, allowing the dough to stretch and rise adequately. Many bakers prefer a blend of bread flour and whole wheat flour or even rye flour for added flavor and a more complex loaf.
You can experiment with different types of flour; some artisan bakers incorporate specialty flours such as spelt or einkorn to create unique flavor profiles. However, it’s essential to maintain a balanced hydration level when substituting these flours, as they often absorb water differently than standard bread flour.
Can I use store-bought sourdough starter?
Yes, you can use a store-bought sourdough starter, especially if you’re just starting or do not have the time to cultivate your own. Many bakeries and specialty food stores sell healthy, active starters that can yield successful results. Make sure to check the freshness and activity level of the starter before purchasing; a bubbly, well-fed starter will produce better bread.
When using a store-bought starter, be sure to follow the feeding instructions provided. It’s essential to acclimate the starter to your baking environment by feeding it for a few days before using it in your bread recipes. This can help ensure that the yeast is strong and active for producing a successful rise and flavor.
How should I store sourdough bread?
Storing sourdough bread properly is crucial to maintaining its fresh taste and texture. To keep the crust crispy, it’s best to store the bread at room temperature in a paper bag or wrapped in a cloth. Avoid plastic bags, as they can trap moisture and soften the crust, leading to a chewy texture. If you plan to consume the bread within a few days, keeping it in a cool, dry area is ideal.
For longer storage, consider freezing your sourdough bread. To do this, slice the bread and wrap it tightly in plastic wrap or aluminum foil, then place it in a freezer-safe bag. When you’re ready to enjoy it, simply toast or reheat the slices directly from the freezer without thawing, preserving the flavor and crust. This method allows you to enjoy your homemade bread long after baking!
