Combine all the ingredients (recipe for homemade ancient grains flour is here) in a large mixing bowl or the bowl of the stand mixer. Mix and knead to make a smooth dough. Dough might be a little sticky, but if it holds its shape, then no need to add more flour.
Place the dough in a lightly greased bowl, cover and let rise for 1½~2 hours, until noticeably puffy, though not doubled in volume.
If you have a covered baker, then gently deflate the dough and shape it into a log and place it in lightly greased baker. Put the lid and allow to rise until it crests 1" over the rim of the pan, about 1½~2 hours.
I didn't have a covered baker, so I shaped the dough into a log and placed it on a parchment lined baking sheet. Covered and let it rise for 1½~2 hours.
Towards the end of the rising time, preheat the oven to 350°F.
Bake the bread for 35~45 minutes or until the interior registers 190°F on a digital thermometer.
Remove from the oven onto a cooling rack. Cool completely before slicing.
