Carolina rice Though South Carolina was once famous not only in the United States but also in Europe for its delicate, white long-grain rice, known as Carolina Gold, commercial rice production gradually died out after the Civil War. However, the name Carolina still evokes a high-quality rice, so some companies now use it to market good-quality generic white long-grain American-grown rices. It is also loosely used to refer to American-style long-grain rices that cook to a dry, separate texture, the classic ideal for Carolina low-country cooks.
