The name of the product was determined in a competition. The competition was held in what was the Norwich factory of Mackintosh's, and won by Barbara Herne. The bar was made at the old Norwich factory until the factory closed in 1996, when production transferred to Fawdon in Tyneside where it is still made. Caramac was temporarily available in Canada, during the 1960s and 1970s.
