Gather all ingredients.

Mix warm water, yeast, and 1/3 cup honey in a large bowl to dissolve.

Add 5 cups bread flour and stir to combine.

Let sit for 30 minutes, or until big and bubbly.

Mix in 3 tablespoons melted butter, remaining 1/3 cup honey, and salt. Stir in 2 cups whole wheat flour.

Transfer dough to a floured work surface and gradually knead in remaining 2 cups whole wheat flour.

Place in a greased bowl, turning once to coat the surface of the dough.

Cover with a dish towel and let rise in a warm place until doubled, 45 minutes to 1 hour.

Grease three 9x5-inch loaf pans. Punch down the dough, and divide it into 3 loaves. Place in the prepared pans, and allow to rise until dough has topped the pans by one inch, another 45 minutes to 1 hour.

Meanwhile, preheat the oven to 350 degrees F (175 degrees C). Bake the risen loaves in the oven until golden brown for 25 to 30 minutes.

Lightly brush the tops of the loaves with remaining 2 tablespoons melted butter when done to prevent crust from getting hard.
