Position a rack in the middle of the oven and preheat the oven to 425F degrees. Line a baking sheet with parchment paper or a silicone baking mat.
In a large bowl, whisk together the flour, whole wheat flour, rolled oats, wheat germ baking soda and salt until well blended.
Cut the butter into very small pieces and add to the flour mixture, Rub the butter into the flour mixture with your fingers until they are as small as possible.
Add the buttermilk and stir to combine until the dough is damp all over.
Place the dough onto a lightly floured counter and gently shape into into a ball.
Place the ball on your lined baking sheet and flatten slightly. Use a serrated knife to cut a 1-inch deep cross in the top of the bread. Sprinkle the top of the loaf with a little flour.
Bake for 30 to 40 minutes, or until the loaf is firm to the touch on top and sounds hollow when tapped on the bottom.
Remove from the oven and place loaf on a wire rack to cool, wrapping a clean towel around so that the crust steams and softens and isn't too hard.
Cool for 2 hours before slicing and serving.
Cut the loaf along the cross lines into four sections, then cut each section into 5 slices.

I'm also going to experiment with less butter and using an egg instead of the butter.
