Preheat oven to 400 and line large rimmed baking sheet with unbleached parchment paper.
In a high-speed blender (Nutribullet will work too), pulverize the wheat berries until they turn into flour.
Using a wooden spoon, in a large mixing bowl, combine the wheat flour, rye flour, baking soda and salt. Add in beer, milk, honey and ACV. Stir until the dough comes together into a slightly sticky ball. If the dough seems too dry, add a splash more beer, if it seems too sticky, sprinkle in additional flour.*
Turn the dough out onto a floured surface and kneed into a rough ball. Place dough on prepared baking sheet, sprinkle with a bit of flour and use a sharp knife to score a cross on the top of the dough.
Bake for 45 minutes, until the loaf has almost double in size and sounds hollow when tapped.
* You can use 2 cups whole wheat flour in place of milling the wheat berries yourself. * You should be able to touch the dough without clumps of it sticking to your hands....but it should also stay together in one ball without dry bits breaking off on their own. * I either make orange marmalade or chia jam to slather on this delicious loaf.
