Grape-Nuts cereal has been a part of American history as an iconic nutritious and delicious breakfast staple and a popular recipe ingredient. Despite its name, Grape-Nuts do not contain grapes nor nuts. Legends state that C.W. Post believed glucose, what he referred to as grape sugar, formed during the baking process. The other tale says it got its name from its resemblance to grape seeds, or grape nuts. Grape-Nuts cereal is made from wheat and barley, packed with whole-grain goodness, and is an excellent source of fiber – giving you the power to climb your personal mountain.
