Grape-nuts cereal
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, in later years, whole wheat so that the cereal could boast the nutritional value. 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, as 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".
