The History of Conrad Rice Mill and the Konriko Brand As America’s oldest operating rice mill, founded in 1912, the Conrad Rice Mill and Konriko Company Store in New Iberia, LA has a reputation as unique as its products, and owners Mike and Sandy Davis plan to keep it that way. Mike and Sandy bought the mill from the Conrad brothers, Julian and Allen Conrad, in 1975. Most visitors know the company mill and store by its more colorful moniker, KONRIKO, which was added to the National Register of Historical Places in 1981. The name is an acronym: “Kon” is the “Con” in Conrad, “Ri” stands for rice and “Ko” is company.
