Sourdough bread has become increasingly popular in recent years due to its distinctive taste, chewy texture, and health benefits. As more people shift to plant-based diets, a common question arises: Is sourdough bread vegan? Given that sourdough’s traditional ingredients are simply flour, water, and salt, you might think it’s always vegan. However, this isn’t always the case.
In this detailed guide, we’ll break down the ingredients typically used in sourdough, explore when sourdough is vegan (and when it isn’t), and provide tips on how to identify and make vegan sourdough bread. Additionally, we’ll dive into whether store-bought sourdough is vegan-friendly and how you can enjoy this delicious bread on a plant-based diet.
What Makes Bread Vegan?
To start, let’s clarify what makes bread vegan. Bread is vegan when it contains no animal-derived ingredients. That means no milk, eggs, butter, or honey—common ingredients in some bread types that are not vegan-friendly.
Key Non-Vegan Ingredients in Bread
Here are some of the most common animal-derived ingredients that can be found in various types of bread:
- Milk: Sometimes used in bread to add moisture and tenderness.
- Butter: Adds richness and flavor.
- Eggs: Occasionally used to create a soft texture or to brush on the crust for a shiny finish.
- Honey: A natural sweetener made by bees, thus not considered vegan.
- Lard: Animal fat used in some traditional bread recipes.
- Animal-based enzymes: These might be included in some commercially produced bread to improve texture or shelf life.

What Is Sourdough Bread?
Sourdough bread is a type of bread that is naturally leavened using a sourdough starter, which is a mixture of flour and water fermented with wild yeast and lactic acid bacteria. The starter is responsible for the bread’s signature tangy flavor and chewy texture. The fermentation process also helps break down gluten, making sourdough easier to digest for many people.
Traditional Sourdough Ingredients
Traditional sourdough bread is made using just four ingredients:
- Flour (usually wheat flour or rye)
- Water
- Salt
- Sourdough Starter: A mixture of flour and water fermented with wild yeast and bacteria
None of these ingredients are derived from animals, which means that traditional sourdough bread is inherently vegan.
Is All Sourdough Bread Vegan?
While traditional sourdough bread is naturally vegan, not all sourdough available on the market follows this simple formula. Commercial bakeries and even some artisan bakers may add non-vegan ingredients to sourdough bread for various reasons, including flavor, texture, or shelf life.
Non-Vegan Ingredients Found in Sourdough
Here are some of the non-vegan ingredients that can sometimes be found in commercially produced or artisan sourdough:
- Milk or Butter: These dairy products might be added to make the bread softer or richer in flavor.
- Eggs: Some bakers use eggs to give the bread a softer texture or a shiny crust.
- Honey: Occasionally used as a natural sweetener in sourdough bread, replacing sugar.
- L-Cysteine: An amino acid derived from animal feathers or hair, used as a dough conditioner in commercial bread production.
- Mono- and Diglycerides: These emulsifiers can be animal-derived and are often used in commercially produced bread to extend shelf life or improve texture.
If you’re buying sourdough from a bakery or grocery store, it’s essential to read the ingredients list or ask the baker about any potential non-vegan ingredients. For more information on bread additives, check out The Vegan Society’s guide to non-vegan ingredients.
How to Tell if Sourdough Bread is Vegan
If you’re unsure whether the sourdough bread you’re buying is vegan, here are some tips to help you make sure:
1. Read the Ingredient List
If the bread is packaged, the easiest way to check if it’s vegan is to read the ingredients label. Look out for any animal-derived ingredients such as:
- Milk
- Butter
- Eggs
- Honey
- L-Cysteine
- Mono- and Diglycerides
If none of these appear on the list, the bread is likely vegan.
2. Ask the Baker
If you’re buying bread from a bakery, don’t hesitate to ask the baker or staff whether the bread contains any animal products. Artisan sourdough is often made with traditional ingredients, but some bakers might add extras for flavor or texture.
3. Look for a Vegan Label
Some bread manufacturers will include a « Certified Vegan » label on their products, making it easy to identify vegan-friendly options. If you see this label, you can be sure that the sourdough bread contains no animal products.

Sourdough Starter: Is It Vegan?
The heart of sourdough bread is the sourdough starter, a fermented mixture of flour and water that contains naturally occurring wild yeast and lactic acid bacteria. Since the starter is made entirely from flour and water, sourdough starter is vegan. The fermentation process doesn’t involve any animal products.
However, some recipes might add non-vegan ingredients to the sourdough dough itself, such as milk or honey. So, while the starter is always vegan, the final product might not be, depending on the additional ingredients used.
Non-Vegan Variations of Sourdough
Although traditional sourdough bread is vegan, many modern recipes introduce non-vegan elements to create different flavors or textures. Here are some common non-vegan variations of sourdough:
1. Sourdough with Milk or Butter
Some recipes incorporate milk or butter into the dough to give the bread a softer, richer texture. These versions are not vegan because they contain dairy products.
2. Sourdough with Honey
Honey is sometimes used as a natural sweetener in artisan sourdough recipes, particularly in varieties like honey wheat sourdough. Since honey is an animal-derived product, this type of sourdough is not vegan.
If you’re looking for sweetened vegan bread, consider using maple syrup or agave as a substitute for honey.
Making Vegan Sourdough Bread at Home
If you want to ensure your sourdough bread is 100% vegan, the best option is to make it yourself at home. By following a traditional sourdough recipe, you can control the ingredients and avoid any animal-derived additives.
Here’s a simple recipe for vegan sourdough bread that you can try:
Ingredients:
- 500g bread flour (white, whole wheat, or rye)
- 300g water
- 100g sourdough starter (made with just flour and water)
- 10g salt
Instructions:
- Mix the Dough: In a large bowl, combine the flour, water, and sourdough starter. Stir until a rough dough forms.
- Rest the Dough: Cover the bowl with a clean towel and let the dough rest for 30 minutes.
- Add Salt: After resting, sprinkle the salt over the dough and knead it in.
- Knead the Dough: Knead the dough on a clean surface for about 5-10 minutes until it becomes smooth and elastic.
- Bulk Fermentation: Place the dough in a lightly oiled bowl, cover, and let it rise at room temperature for 3-4 hours. Stretch and fold the dough every 30 minutes to help develop the gluten.
- Shape the Dough: After the first rise, shape the dough into a round or oval loaf and place it in a proofing basket.
- Final Proof: Cover the basket with a towel and let the dough proof in the refrigerator overnight (12-16 hours).
- Bake the Bread: Preheat your oven to 450°F (230°C) and place a Dutch oven inside to heat up. Once hot, transfer the dough into the Dutch oven and bake for 25-30 minutes with the lid on, then 10-15 minutes with the lid off for a golden crust.
This recipe uses only flour, water, and salt, ensuring it’s completely vegan.
Is Store-Bought Sourdough Bread Vegan?
If you don’t have time to bake sourdough bread at home, you might turn to store-bought options. While some store-bought sourdoughs are vegan, not all are, so it’s important to check the ingredients list carefully.
