It was customary for farmers to set aside a portion of their inferior grain to be made into whisky, and as Corby was already making whisky for the locals, he became interested in the distilling process. In 1857, Corby built a dam and established a grist-mill on the bank of the Moira River. In 1859 he built a distillery which became more important than the mill. ( I am pretty sure this mill was built long before that by Wm Reed and his Son, about 1812, or at least there was another built back then)
