1. In a large mixing bowl, combine all-purpose flour, rye flour, whole wheat flour, cocoa powder, brown sugar, coffee granules, caraway seeds, salt, and yeast.
2. Add warm water, molasses, and vegetable oil. Mix until a dough forms.
3. Knead the dough on a floured surface for about 10 minutes, until smooth and elastic.
4. Place the dough in a greased bowl, cover, and let rise in a warm place for about 1 hour, or until doubled in size.
5. Preheat oven to 375°F (190°C). Punch down the dough and shape it into a loaf. Place in a greased loaf pan.
6. Bake for 35 minutes, or until the bread sounds hollow when tapped. Let cool before slicing.
