Sourdough Flour Blend Bread – Balanced Artisan Recipe for Flavor and Structure

by

Blending different types of flour is one of the best ways to elevate your sourdough bread. While bread flour provides strength and structure, whole grain flours add depth of flavor, nutrients, and complexity. This combination creates a loaf that is both strong and flavorful, with a soft crumb and crisp crust.

This sourdough flour blend bread recipe uses an 80/20 ratio of bread flour to whole wheat flour, which is ideal for achieving balance. The bread flour ensures good gluten development and oven spring, while the whole wheat flour enhances taste and fermentation activity.

Whether you are a beginner or an experienced baker, this recipe offers a reliable method to produce artisan-quality sourdough bread with improved texture and nutrition.

Why Use a Flour Blend in Sourdough?

Using a mix of flours provides several advantages.

Bread flour contains high protein, which forms strong gluten and supports an open crumb.

Whole wheat flour contains bran and germ, which add flavor and nutrients while increasing fermentation activity.

The combination results in:

  • Better dough strength

  • More complex flavor

  • Improved nutritional value

  • Balanced crumb structure

An 80/20 blend is perfect because it keeps the dough manageable while still benefiting from whole grain properties.

Ingredients

Full Ingredient List (80/20 Blend)

400 g bread flour
100 g whole wheat flour
350 ml water
100 g active sourdough starter
10 g salt

Use warm water at 26–28°C (78–82°F) to encourage proper fermentation.

Step-by-Step Method

Mix and Autolyse

In a large bowl, combine:

  • bread flour

  • whole wheat flour

  • water

Mix until a shaggy dough forms.

Cover and let the dough rest for 30–45 minutes.

This step, called autolyse, allows the flour to fully hydrate and begins gluten development naturally.

Add Starter and Salt

Add the sourdough starter and salt to the dough.

Mix thoroughly until everything is evenly incorporated.

At this stage, the dough will begin to feel smoother and more cohesive.

Stretch and Fold

Perform stretch-and-folds every 30 minutes for 2 hours.

Lift one side of the dough, stretch it upward, and fold it over the center.

Rotate the bowl and repeat on all sides.

This process strengthens gluten and helps the mixed flours develop structure.

Bulk Fermentation

Cover the dough and allow it to ferment.

  • Time: 4–6 hours

  • Temperature: 24–26°C (75–79°F)

The dough should become:

  • Airy

  • Slightly domed

  • Elastic

Proper fermentation is key to achieving a light crumb and good flavor.

Shape the Dough

Transfer the dough onto a lightly floured surface.

Shape it into a round or oval loaf by creating surface tension.

Allow the dough to rest for:

  • 60–90 minutes at room temperature
    or

  • Cold proof for 8–12 hours for deeper flavor

Bake the Bread

Preheat your oven with a Dutch oven inside.

  • Temperature: 230°C (450°F)

Score the dough with a sharp blade.

Bake:

  • 20 minutes covered

  • 20–25 minutes uncovered

This method creates steam inside the pot, helping the bread expand and develop a crispy crust.

Cool Before Slicing

Allow the bread to cool for at least 1 hour before slicing.

Cooling helps the crumb set and prevents a gummy texture.

Flour Blend Variations

Different flour combinations produce different results.

90% Bread Flour + 10% Rye

  • Faster fermentation

  • Deeper, slightly tangy flavor

70% Bread Flour + 30% Spelt

  • Softer crumb

  • Slightly nutty taste

50% All-Purpose + 50% Bread Flour

  • Balanced rise

  • Good for beginners

80% Bread Flour + 20% Einkorn

  • Slightly sweet flavor

  • Softer dough texture

Experimenting with blends allows you to customize flavor and texture.

Tips for Perfect Flour Blend Sourdough

Use an active sourdough starter that has recently doubled.

Adjust hydration slightly if using whole grain flours, as they absorb more water.

Avoid overhandling the dough to preserve air bubbles.

Use a Dutch oven or steam for the best crust.

Allow proper fermentation time for full flavor development.

Baking Science Behind Flour Blends

Whole wheat flour contains bran, which can slightly weaken gluten but increases water absorption.

Bread flour compensates by providing strong gluten structure.

This balance allows the dough to remain strong while developing a more complex flavor profile.

The result is bread with both structure and character, combining the best qualities of refined and whole grain flours.

Serving Suggestions

This sourdough bread pairs well with many foods.

Serve with olive oil and herbs.

Use for sandwiches or toast.

Pair with soups, salads, or cheese boards.

Enjoy with honey or jam for a simple snack.

Storage Tips

Store bread at room temperature in a cloth bag or bread box for up to 3 days.

Avoid refrigeration, as it can dry out the bread.

For longer storage, slice and freeze for up to 1 month.

Frequently Asked Questions

Can I increase whole wheat flour?

Yes, but higher percentages may make the bread denser and require more hydration.

Why is my dough tighter with whole wheat?

Whole wheat absorbs more water and contains bran, which affects gluten development.

Can I skip cold proofing?

Yes, but cold proofing improves flavor and scoring results.

How do I get a more open crumb?

Use proper fermentation, gentle handling, and slightly higher hydration.

Conclusion

Sourdough flour blend bread offers the perfect balance between structure and flavor. By combining bread flour with whole wheat flour, you can create a loaf that is both strong and nutritious, with a soft crumb and crisp crust.

This 80/20 artisan recipe is ideal for bakers who want to improve their sourdough results while keeping the process manageable. With practice, experimenting with different flour blends will allow you to customize your bread and develop your own signature style.
