Freshly milled heritage grain flour is one of the biggest upgrades a home baker can make, but not all home grain mills perform the same. In this detailed comparison, a friend of Palouse Heritage, a trained chemist and experienced home baker, tested several popular home mills to evaluate flour fineness, extraction rates, sifting performance, and overall usability. The results reveal how mills like the Mockmill 200, Nutrimill Classic, and Mockmill KitchenAid attachment compare in real-world baking applications, while also highlighting why heritage grains and fresh milling consistently produce superior flavor, nutrition, and baking performance compared to modern store-bought flour.
