Wheat grains are ground into flour before cooking/baking into food. For 400 years, wheat seeds (mostly starch, but with gluten-rich proteins) have been processed at mills all across Virginia for making bread and other baked goods. Today, stone millwheels are primarily decorative items, but a few still-operating mills require millers to "keep their nose to the grindstone" to check the quality of the flour.
almost all gristmills in Virginia were powered by water until diesel engines became readily available

wheat grains or corn kernels dropped from a square hopper and ended up between the circular grindstones, before emerging as flour/cornmeal

Mills were centers of community as well as industrial operations. Small mills ground wheat and other grains for local farmers, who often took home the flour from their own crop (minus the portion of "toll" paid to the miller). Merchant mills paid cash for wheat, then sold the flour separately.
Thomas Jefferson built two flour mills on the Rivanna River, plus a separate sawmill complex. He reserved one of the flour mills to grind grain for his own use, and leased the second mill for commercial use to grind grain for others.1
soon after the end of the Revolutionary War, Nathaniel Burwell and Daniel Morgan built a merchant mill in what became known as Millwood to grind grain produced by local wheat farmers

key parts within the mills were constructed from locally-available timber

The Chapman/Beverly Mill in Thoroughfare Gap (on the border of Prince William and Fauquier counties) was expanded to 7 stories in 1758 to become one of the tallest stone structures in the United States. The expansion of the mill, almost 100 years after it was originally built, occurred after the Manassas Gap Railroad connected the mill directly to the port of Alexandria in 1752.
