Mill about 3 cups of hard white or hard red wheat berries to yield 4 1/2–4 3/4 cups freshly milled flour.
In the bowl of a stand mixer, combine 2 cups warm water, 1 tablespoon instant yeast, and 1 cup of the freshly milled flour. Mix together.
Cover and let sit for 15–20 minutes, or until bubbly.
Add 1/4 cup honey, 1/4 cup oil, 1 1/2 teaspoons salt, and the remaining flour.
Mix until a soft dough forms and begins pulling away from the sides of the bowl, adding more flour only as needed.
Knead with the dough hook for 9–10 minutes (or by hand for 15–20 minutes) until the dough is soft, stretchy, and slightly sticky.
Shape into 1 large 2-pound loaf or 2 small 1-pound loaves and place in greased loaf pans.
Cover and let rise until the dough is about 1 inch above the rim of the pan (about 30 - 40 minutes)
Bake at 350°F for 35 minutes, or until golden brown.
Let cool in the pans for 10 minutes, then transfer to a wire rack to cool completely before slicing.
