Grape-Nuts is a breakfast cereal made from whole grain wheat and barley. It was created in 1897 by Charles W. Post, an American inventor and entrepreneur. The cereal is known for its crunchy texture and nutty flavor, and it is often enjoyed with milk or yogurt. Despite its name, Grape-Nuts does not contain grapes or nuts. The name comes from the unique flavor of the cereal, which is said to resemble the taste of grapes, and the "nutty" texture of the toasted grains. Grape-Nuts is a source of fiber and is often marketed as a healthy breakfast option.
