Whole wheat sourdough has a rich, slightly nutty flavor, a hearty texture, and all the naturally fermented goodness people love about sourdough bread.

It can also be a little trickier than a basic white loaf.

Whole wheat flour absorbs more water, ferments more quickly, and can make the dough feel heavier. That is why this recipe uses a blend of whole wheat flour and bread flour instead of going straight to 100 percent whole wheat.

You still get plenty of whole grain flavor, but the dough remains easier to fold, shape, and bake.

My Whole Wheat Sourdough Recipe

When you are ready to move beyond a basic sourdough loaf, whole wheat is a great next step.

I do not recommend that complete beginners start with a 100 percent whole wheat dough. It can be denser, stickier, and less forgiving while you are still learning fermentation.

This recipe uses 30 percent whole wheat flour and 70 percent bread flour.

That balance gives the loaf a deeper flavor and more whole grain character without sacrificing too much structure or oven spring.

It is still soft enough for sandwiches and toast, but it has a slightly heartier crumb than a traditional white sourdough loaf.

Why You Will Love This Recipe

This whole wheat sourdough bread is:

• Beginner friendly
• Made with simple ingredients
• Higher in whole grains
• Soft enough for sandwiches
• Flavorful without being overly dense
• Naturally fermented
• Easy to customize with seeds, oats, or honey

Whole Wheat Sourdough Ingredients

• 150 grams active sourdough starter
• 350 grams water
• 400 grams bread flour
• 100 grams whole wheat flour
• 10 grams salt

This recipe uses 20 percent whole wheat flour.

The slightly higher amount of water helps account for the extra absorption from the whole wheat flour.

Equipment

You will need:

• Digital kitchen scale
• Large mixing bowl
• Dough whisk, spoon, or clean hands
• Bench scraper
• Proofing basket or towel-lined bowl
• Dutch oven or covered bread baker
• Parchment paper or bread sling
• Bread lame or sharp knife
• Cooling rack

Before You Begin

Use an active sourdough starter that has been recently fed and is rising predictably.

Ideally, your starter should have doubled in size and be near its peak when you mix the dough.

Whole wheat flour contains more nutrients than white flour, which can cause fermentation to move more quickly.

This means the dough may be ready to shape sooner than your regular white sourdough.

Watch the dough closely during bulk fermentation.

How to Make Whole Wheat Sourdough Bread

Step 1: Mix the Starter and Water

Add 150 grams of active sourdough starter and 350 grams of water to a large mixing bowl.

Stir until the starter is mostly dissolved.

The mixture does not need to be completely smooth.

Step 2: Add the Flour and Salt

Add:

• 400 grams bread flour
• 100 grams whole wheat flour
• 10 grams salt

Mix until no dry flour remains.

You can use a dough whisk, spoon, or your hands.

The dough may feel slightly rough, sticky, and heavier than a white-flour dough.

This is normal.

Continue mixing or lightly kneading the dough for approximately five minutes.

Cover the bowl and allow the dough to rest for one hour.

Step 3: Complete the First Stretch and Fold

Dampen your hands with water.

Grab one side of the dough and gently stretch it upward.

Fold it over the center.

Rotate the bowl and repeat on all four sides.

Cover the dough and allow it to rest for approximately 30 minutes.

Step 4: Complete the Second Stretch and Fold

Repeat the stretch-and-fold process.

The dough should begin feeling smoother and more elastic.

Cover and allow it to rest for another 30 minutes.

Step 5: Complete the First Coil Fold

Place damp hands underneath the center of the dough.

Lift the dough gently and allow the ends to fold underneath themselves.

Rotate the bowl and repeat from the opposite direction.

Cover the bowl and rest the dough for approximately 30 minutes.

Step 6: Complete the Final Coil Fold

Repeat the coil-fold process one more time.

After the final fold, the dough should hold its shape better and feel stronger.

You will complete:

• Two sets of stretch and folds
• Two sets of coil folds

Whole wheat dough may not become as smooth or stretchy as white sourdough dough.

That does not mean anything is wrong.

Step 7: Bulk Ferment the Dough

Cover the bowl and allow the dough to continue fermenting at room temperature.

Bulk fermentation begins as soon as the starter is mixed into the dough.

The exact amount of time will depend on:

• Dough temperature
• Room temperature
• Starter strength
• Flour choice
• Percentage of whole wheat flour

Whole wheat dough often ferments faster than white sourdough.

Look for these signs that the dough is ready to shape:

• It has increased noticeably in size
• The surface looks slightly domed
• Bubbles are visible along the sides or top
• The dough jiggles when the bowl is moved
• It feels lighter and airier
• The edges begin pulling slightly away from the bowl

The dough does not need to double.

In a warm kitchen, a rise of approximately 30 to 50 percent may be enough.

Do not wait until the dough becomes extremely loose, sticky, or collapsed.

Those may be signs of over-fermentation.

Step 8: Pre-Shape the Dough

Lightly flour your work surface.

Gently turn the dough out of the bowl.

Use a bench scraper to guide it into a loose round.

Try not to press out all the air.

Allow the dough to rest uncovered for approximately 15 to 20 minutes.

Whole wheat dough may relax and spread slightly more than white dough during this rest.

That is normal.

Step 9: Shape the Dough

Lightly flour the top of the dough and flip it over.

Gently stretch it into a loose rectangle.

Fold the left side toward the center.

Fold the right side toward the center.

Roll the dough upward into a compact shape.

Use your hands or a bench scraper to gently pull the dough across the counter and create surface tension.

Do not pull so tightly that the dough tears.

Step 10: Place the Dough in a Proofing Basket

Generously flour your proofing basket.

Rice flour works especially well for preventing sticking.

Place the shaped dough into the basket with the seam side facing upward.

Cover and place it in the refrigerator.

Cold proof the dough for at least one hour and up to 24 hours.

An overnight cold proof gives the loaf more flavor and makes it easier to score.

Step 11: Preheat the Oven

Place your Dutch oven inside the oven.

Preheat the oven and Dutch oven to 450°F.

Allow the Dutch oven to heat for approximately 30 to 45 minutes.

A fully preheated Dutch oven helps create steam and supports better oven spring.

Step 12: Score the Dough

Remove the dough from the refrigerator.

Turn it out onto parchment paper or a bread sling.

Brush away excess flour.

Use a bread lame or sharp knife to make one main expansion score.

The cut should be approximately ¼ to ½ inch deep.

Whole wheat dough may not open as dramatically as a white loaf, but it should still expand during baking.

Step 13: Bake the Bread

Carefully place the dough into the hot Dutch oven.

Cover with the lid.

Bake at 450°F for 25 minutes.

Remove the lid and continue baking for approximately 20 minutes.

The crust should be deeply golden brown.

Whole wheat loaves may appear darker than white sourdough because of the flour.

The internal temperature should reach at least 205°F.

Step 14: Cool Completely

Transfer the loaf to a cooling rack.

Allow it to cool for at least one to two hours before slicing.

Whole wheat bread can become especially gummy if cut too soon.

Cooling gives the crumb time to finish setting.

Tips for Whole Wheat Sourdough Bread

Start With a Blend of Flours

A mixture of whole wheat flour and bread flour is easier for beginners than a 100 percent whole wheat loaf.

Bread flour helps provide structure and strength.

Whole wheat flour adds flavor, color, and a heartier texture.

Expect a Different Dough Texture

Whole wheat dough may feel:

• Slightly rougher
• Less stretchy
• More absorbent
• Heavier
• Stickier during shaping

Do not expect it to behave exactly like white sourdough dough.

Do Not Add Too Much Extra Flour

Whole wheat dough may feel sticky even when the hydration is correct.

Use damp hands during folding and a lightly floured surface during shaping.

Adding too much flour can make the loaf dry and dense.

Watch Fermentation Carefully

Whole wheat flour can speed up fermentation.

Check the dough earlier than you normally would.

A dough that ferments too long may become loose, sticky, and difficult to shape.

Give the Flour Time to Hydrate

The one-hour rest after mixing is especially helpful for whole wheat flour.

It allows the bran and germ to absorb water and soften.

The dough should feel more manageable after the rest.

Do Not Expect Giant Holes

Whole wheat sourdough often has a tighter crumb than white sourdough.

The bran in whole wheat flour can interfere with gluten development.

A slightly tighter crumb is normal and works beautifully for sandwiches and toast.

Common Whole Wheat Sourdough Problems

Why Is My Whole Wheat Sourdough Dense?

A dense loaf may be caused by:

• Weak sourdough starter
• Under-fermentation
• Too much whole wheat flour for the dough strength
• Too much extra flour added during shaping
• Cutting the loaf before it cooled
• Dough that was too cool
• Insufficient gluten development

Why Is My Dough So Sticky?

Whole wheat flour absorbs more water, but the dough can still feel sticky because of the higher hydration.

It should become stronger after resting and folding.

If it becomes extremely loose near the end of bulk fermentation, it may have fermented too long.

Why Did My Loaf Spread?

The loaf may spread if:

• The dough was over-fermented
• The final shape was too loose
• The dough did not develop enough strength
• The proofing basket was too large
• Too much water was used for your specific flour

Different brands of whole wheat flour absorb different amounts of water.

You may need to reduce the water by 10 to 20 grams if your dough feels excessively loose.

Can I Use More Whole Wheat Flour?

Yes.

You can gradually increase the whole wheat flour as you become more comfortable.

For a 50 percent whole wheat loaf, use:

• 250 grams bread flour
• 250 grams whole wheat flour

You may also need to add another 10 to 20 grams of water.

Higher percentages of whole wheat flour usually produce a denser, heartier loaf.

Can I Use White Whole Wheat Flour?

Yes.

White whole wheat flour is still a whole grain flour, but it has a milder flavor than traditional whole wheat flour.

It is a good option if you want a lighter-tasting loaf.

Can I Add Honey?

Yes.

Add 20 to 30 grams of honey when mixing the starter and water.

Honey will add a mild sweetness and may make the crust brown more quickly.

Can I Add Seeds?

Yes.

You can add approximately 50 to 75 grams of seeds after the dough has developed some strength.

Good options include:

• Sunflower seeds
• Pumpkin seeds
• Sesame seeds
• Flaxseeds
• Poppy seeds

Soaking larger or highly absorbent seeds before adding them can help prevent them from pulling moisture from the dough.

How to Store Whole Wheat Sourdough Bread

Allow the loaf to cool completely before storing it.

Store the bread:

• Cut-side down on a cutting board
• In a bread box
• In a bread bag
• Loosely wrapped in a clean kitchen towel

Avoid storing sourdough bread in the refrigerator because it can stale more quickly.

For longer storage, slice the loaf and freeze it.

Frozen slices can be toasted directly from the freezer.

Recipe Notes

Whole wheat flour absorbs more water and may cause the dough to ferment faster than a basic white sourdough loaf.

Begin checking the dough earlier during bulk fermentation.

If the dough feels too stiff after mixing, add 5 to 10 grams of water at a time.

If it feels excessively loose, reduce the water by 10 to 20 grams the next time you make the recipe.

Whole wheat sourdough usually has a slightly tighter crumb and less dramatic oven spring than white sourdough.

This is normal.

For a softer crust, cool the loaf under a clean kitchen towel.

For a darker crust, bake uncovered for a few additional minutes.

Final Thoughts

Whole wheat sourdough does not need to be heavy, dry, or intimidating.

Starting with a blend of whole wheat flour and bread flour gives you the flavor and character of whole grains while keeping the dough approachable.

Once you understand how this dough feels and ferments, you can begin increasing the whole wheat percentage or adding ingredients such as honey, oats, nuts, and seeds.

It is a simple step beyond a basic loaf, but it opens the door to an entire wheat field of possibilities.
