how did grape nuts cereal get its name
Despite the name, the cereal contains neither grapes nor nuts; it is made with wheat and barley. Post believed that glucose (which he called "grape sugar") formed in 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 a resemblance to grape seeds, or grape "nuts".
