Let’s dive into all the details and see who emerges winner in this sourdough bread vs white bread debate.

What gives sourdough bread that nutritional edge over regular white bread? Are there other benefits that sourdough bread provides? Let’s find the anwers!  

what is sourdough bread

Sourdough bread is a type of bread made using a natural fermentation process involving wild yeast and lactic acid bacteria. Unlike regular white bread, which relies on commercial yeast for rising, sourdough uses a “starter” that captures wild yeast from the environment. This starter is a mixture of flour and water that ferments over time.

Sourdough is one of the oldest forms of grain fermentation, dating back thousands of years. It was the predominant form of leavened bread until the introduction of commercial yeast in the 19th century. Today, sourdough is appreciated for its unique tangy flavour and chewy texture.

Sourdough Bread vs White Bread: What is the Main Difference?

Sourdough bread is fermented using wild yeast and bacteria that are naturally cultivated. These microbes break down the carbohydrates in the flour, releasing carbon dioxide and lactic acid, which give the bread its peculiar sour flavor. This technique improves not just the flavor of the bread but also its nutritional content and digestibility.

Top 4 differences between sourdough bread and white bread: 

  1. Yeast Type: Sourdough uses wild yeast and LAB (Lactic Acid Bacteria); white bread uses commercial yeast.
  2. Fermentation Time: Sourdough has longer fermentation periods; white bread has shorter ones.
  3. Flavor: Sourdough develops more complex, tangy flavors; white bread is milder.
  4. Texture: Sourdough has a chewier texture with an open crumb; white bread is softer with a more uniform crumb.

Benefits of Sourdough Over White Bread

sourdough vs whitebread what differs

To understand further why sourdough bread is better than white bread, let’s understand the benefits of sourdough bread vs white bread:

1. Nutrient Content

Sourdough generally has a higher content of vitamins and minerals compared to regular white bread. It is particularly rich in B vitamins, iron, and magnesium.

a. Comparison of Vitamins and Minerals in Sourdough vs. White Bread

  • Sourdough: Higher levels of B vitamins, iron, magnesium, and antioxidants.
  • White Bread: This type of bread is often lower in these nutrients due to the refining process.

b. Lower Glycemic Index

Sourdough bread has a lower glycemic index (GI) than white bread. This means it causes a slower, more gradual rise in blood sugar levels, making it a better option for managing blood sugar. That’s the reason why people looking to eat healthier are advised to go for sourdough bread, and to avoid white bread.

c. Higher Protein and Fiber Content

Sourdough typically contains more protein and fiber. This eventually leads to better digestion and prolonged feelings of fullness which will ultimately help maintaining weight. 

2. Digestibility

a. Natural Fermentation Process

In case of sourdough bread, the natural fermentation process breaks down gluten, making it easier to digest for individuals who are gluten-sensitive.

b. Role in Gut Health

Sourdough contains lactic acid bacteria, which helps to maintain a healthy gut microbiome and boost general digestion and immunological function.

3. Flavor and Texture

The fermentation process gives sourdough a complex, tangy flavor that is more pronounced than the bland taste of white bread.

How Does Fermentation Process Affect The Texture?

Sourdough has a distinct flavor profile due to the formation of lactic and acetic acids during fermentation. It is renowned for its chewy crust and airy, open-crumb structure. The long fermentation process and natural leavening result in a pleasant crusty and tender texture.

4. Health Benefits

a. Beneficial Acids

Sourdough contains lactic acid, which can improve nutrient absorption and reduce phytic acid, an antinutrient.  Lactic acid helps increase the bioavailability of minerals and can have a mild preservative effect.

b. Antioxidants

Sourdough has higher levels of antioxidants compared to white bread.

c. Potential Anti-inflammatory Properties

The combination of beneficial bacteria, acids, and antioxidants in sourdough can help reduce inflammation.

5. Longevity and Preservation

The natural acids in sourdough act as preservatives, extending the bread’s shelf life. These natural preservatives reduce the growth of mold and bacteria. Sourdough’s natural preservation properties reduce the need for artificial additives and preservatives.

6. Environmental Impact

Sustainability of Sourdough Production

Sourdough production can be more sustainable, as it relies on wild yeast rather than commercial yeast. It is often produced by local artisans, supporting local economies and sustainable practices.

How to Make Sourdough Bread at Home: Easy Step-by-Step Guide for Beginners

Making sourdough bread at home can be a satisfying and delightful experience. Here’s a detailed step-by-step instruction to get you started: 


For the Sourdough Starter:

  • 100 grams (3/4 cup) whole wheat or rye flour
  • 100 grams (1/2 cup) water

For the Sourdough Bread:

  • 500 grams (4 cups) bread flour
  • 350 grams (1 1/2 cups) water
  • 100 grams (1/2 cup) active sourdough starter
  • 10 grams (1 1/2 teaspoons) salt


  • Large mixing bowl
  • Measuring scale
  • Plastic or wooden spatula
  • Bench scraper
  • Banneton (proofing basket) or a bowl lined with a tea towel
  • Dutch oven or baking stone
  • Parchment paper
  • Sharp knife or bread lame

Step-by-Step Instructions

Step 1: Make the Sourdough Starter

  1. Day 1: In a clean jar, combine 100 grams of whole wheat or rye flour and 100 grams of water. Stir thoroughly, cover loosely with a lid or cloth, and leave at room temperature for 24 hours.
  2. Day 2-7: Discard half of the starter. Feed the leftover starter with 100 g flour and 100 g water. Stir thoroughly, cover loosely, and allow to sit. Repeat the technique every 24 hours until the starter is bubbling and emits a lovely, tangy aroma.

Step 2: Prepare the Dough

  1. Mix the Dough: In a large mixing bowl, combine 500 grams of bread flour and 350 grams of water. Mix until all the flour is hydrated. Cover and let it rest for 30 minutes (autolyse).
  2. Add Starter and Salt: After the above sep, add 100 grams of active sourdough starter and 10 grams of salt to the dough. Mix until it gets fully incorporated.

Step 3: Bulk Fermentation

  1. Stretch and Fold: Repeat a sequence of stretches and folds every 30 minutes for the following 3-4 hours. To stretch and fold, take the dough’s edge, stretch it upward, and fold it over itself. Rotate the bowl and repeat four times (once on each side).
  2. First Rise: Allow the dough to rest at room temperature for 1-2 hours after the final stretch and fold, until it has expanded in size by approximately 50%.

Step 4: Shape the Dough

  1. Pre-shape: Turn the dough out onto a lightly floured surface. Use a bench scraper to gently form it into a circle. Allow it to rest for 20 to 30 minutes.
  2. Final Shape: Once the dough has rested, form it into a tight round or oval loaf. Place the seam-side up in a lightly floured banneton or bowl lined with a floured tea towel.

Step 5: Proof the Dough

Cover the dough and let it proof in the refrigerator for 12-18 hours. This slow fermentation develops flavor and texture

Step 6: Bake the Bread

  1. Preheat the Oven: Preheat the oven to 500°F (260°C) for at least 30 minutes.
  2. Score the Dough: Remove the dough from the refrigerator and turn it out onto a piece of parchment paper. Score the top of the dough with a sharp knife or bread lame.
  3. Bake: Carefully transfer the dough into the preheated Dutch oven or onto the baking stone. Cover (if using a Dutch oven) and bake for 20 minutes. Then, reduce the oven temperature to 450°F (230°C) and bake for an additional 20-25 minutes, or until the crust is deeply golden and the internal temperature reaches 200°F (93°C).

Step 7: Cool and Enjoy

Remove the bread from the oven and let it cool completely on a wire rack before slicing. This ensures the crumb sets properly and enhances the flavor.

Here are a few key points to note for a successful bake: 

  • Active Starter: Make sure your starter is bubbly and active before using it in your dough.
  • Hydration: Adjust the water amount based on your flour and environmental conditions. The dough should be slightly sticky but manageable.
  • Patience: Sourdough baking requires patience and practice. Do not be dismayed if your first loaf isn’t perfect!

Enjoy the process of making and savoring your homemade sourdough bread!

Frequently Asked Questions

Here are some interesting FAQs on sourdough bread vs white bread:

The primary difference lies in the fermentation process. Sourdough bread is made using a natural fermentation process involving wild yeast and lactic acid bacteria, whereas regular white bread uses commercial yeast for a quicker rise.

Yes, sourdough bread is generally considered healthier than regular white bread. It has a lower glycemic index, which helps manage blood sugar levels, and it’s richer in vitamins, minerals, and antioxidants.

While sourdough bread is easier to digest due to the breakdown of gluten during fermentation, it is not gluten-free and may not be suitable for people with celiac disease. However, some individuals with mild gluten sensitivities may find they can tolerate sourdough better than regular bread.

A sourdough starter is ready to use when it is bubbly and has a pleasant, slightly tangy aroma. It should double in size within 4-6 hours after feeding. If your starter passes the float test—where a small amount of starter floats in water—it is active and ready to be used in baking.

Sourdough bread has a longer shelf life due to the presence of natural acids produced during fermentation. These acids act as natural preservatives, inhibiting the growth of mold and bacteria. This reduces the need for artificial preservatives and helps the bread stay fresh longer.
