100% Whole Grain Sourdough Bread

How to make 100% whole grain sourdough bread

4.4 from 5 reviews

This 100% whole grain sourdough bread is rich and delicious. It is perfect sliced fresh with butter or toasted for breakfast. It can be made with rye, barley, spelt, or whole wheat. See the section above for more details on each of these flours.


Units Scale
  • 7 cups (31 oz) whole grain flour (see section above for details)
  • 3 cups (24 oz) warm water
  • 1 cup (7 1/4 oz) sourdough starter
  • 1 Tbsp salt
  • 1/2 tsp instant yeast (optional, to improve the rise)


  1. Warm the water to approx. 32-35 C / 90-95 F, and mix with the flour. Leave the flour to hydrate for 15-30 minutes.
  2. Using the pincer method, mix in the sourdough starter, salt, and yeast. The dough should be stiff but not dry. If needed add a bit more water or flour. The hydration ratio will change depending on the type of flour you’re using.
  3. Allow to rise in a warm location until doubled in volume (about 5 hours). Use the dough folding procedure 3-4 times during this rise (see notes).
  4. Place the dough on a well-floured surface and cut into 2 equal pieces.
  5. Gently shape the dough into a ball, using flour as needed, but avoid kneading.
  6. Place the dough balls in floured baskets, then place them in an air-tight container and leave it in the refrigerator overnight. (We use mixing bowls lined with floured tea towels with dinner plates on top of the bowls).
  7. Preheat oven to 500 F (250 C).
  8. I recommend baking in a cast iron dutch oven or a metal loaf pan as free form baking will result in a flat loaf of bread. See notes for details on each of these methods. 
  9. Bake for 40 to 55 minutes, until the loaf is browning and sounds hollow when tapped on the bottom.
  10. Cool on a rack before slicing.


  • This recipe requires an active sourdough starter. I recommend making your own rather than buying one. Rye is especially good at catching a sourdough culture. The extra yeast isn’t necessary if you have a very healthy sourdough starter.
  • For more information on the pincer method and folding, techniques check out my post on basic sourdough bread techniques.
  • When baking in a loaf pan, probably 45 minutes will be sufficient.
  • To bake in a cast iron dutch oven (recommended), place the dutch oven in the oven to preheat. Then bake the loaf for 30 minutes with the lid on. Remove the lid, and bake for another 20 minutes, until done.
