"Gloucester Chronicle" also mentions that "Hercules" (stoneground) wheatmeal flour and barley meal was produced by the Company at North Mill.

Ballycopeland produced oatmeal and wheatmeal for human consumption, as well as animal feed such as shelled and bruised oats, yellow meal (from maize), kibbled (crushed) grain for poultry and ground peas and beans.

Three pairs of millstones sit at the 'stone' floor - one set for making wheatmeal, one for shelling the grains of corn (a process which separated the useless 'hulls' from the valuable 'seeds' or grain) and a set for grinding grains into oatmeal.
