I have tried, and tried, and tried to make a 100% whole wheat sourdough risen bread. It doesn't work. My duck flock has enjoyed the results, but no one else. But by carefully adapting directions from Breadtopia, I finally got this!
The key is some white flour. Sourdough works a lot better on white flour, so the bolting step is not because they preferred white bread (although they did), it's vital to getting it to rise. I used all-purpose flour rather than bread flour, as English medieval wheat was low in gluten.

Verdict: Fabulous. Look at the inside!
Mmmm. It is pretty darn dense, but not brick-like. It had a beautiful, crispy crust and a chewy inside. I scoffed the heels before anyone else could get them... for quality control. It was enjoyed by all who hadn't recently had dental surgery.
