Grape-Nuts is a breakfast cereal developed by C. W. Post in 1897. Post was a patient and later competitor of the 19th-century breakfast food innovator, Dr. John Harvey Kellogg. Despite its name, the cereal contains neither grapes nor nuts. The cereal is actually made from wheat and barley. Mr. Post believed that sucrose (which he called 'grape sugar') formed during the baking process. This, combined with the nutty flavor of the cereal, is said to have inspired its name. Another explanation originates from employees at Post, who claim that the cereal got its name due to its resemblance to grape seeds, or grape 'nuts.' The cereal originally prepared by C. W. Post when he was developing the product was a batter that came out of the oven as a rigid sheet. He then broke the sheet into pieces and ran them through a coffee grinder to produce the 'nut' sized kernels. Grape-Nuts was initially marketed as a natural cereal that could enhance health and vitality, and also as a 'brain food.'
