In a stone mill, the entire grain kernel in its natural, original state is ground—bran, germ, and endosperm. The result is naturally whole grain flour with all of the nutrition, vitamins, and minerals of the grain.

The sourdough fermentation process improves the bread’s nutritional value and the lactic acid bacteria present in sourdough bread have the ability to release antioxidants during sourdough fermentation. The lower pH of sourdough breads degrades phytates, which interferes with nutrition absorption by binding to certain dietary minerals including iron, zinc, manganese and, to a lesser extent calcium.
