By Arvin Donley. It's been said the first flour miller was the first person who chewed on a wheat kernel. While the details of that milestone will never be known, we do know the transition to using millstones instead of molars to extract flour occurred around 6000 BC, and it remained the primary flourmaking method for many centuries.
