Grape-Nuts is a breakfast cereal consisting of small, hard, spherical pellets made from wheat flour, malted barley, and salt, first produced in 1897 by C.W. Post in Battle Creek, Michigan. Despite its name, the cereal contains neither grapes nor nuts; the "grape" designation reportedly derives from the grape sugar (glucose) produced during the malting process, while "nuts" refers to the nutty flavor developed through roasting and the cereal's small nodular shape. The production process involves mixing grain ingredients with water, heating the dough, drying it thoroughly, breaking it into small pieces, and toasting until hard and crunchy. The result is a particularly dense and crunchy cereal with a mildly sweet, grain-forward flavor profile and slight nuttiness from the malted barley and roasting.

Grape-Nuts represents one of the earliest ready-to-eat cereals in American food history and remains notable for its austere, hard texture that distinguishes it from softer contemporary cereals. The pellets are intentionally durable, designed to maintain their crunch in milk for extended periods.

Grape-Nuts is traditionally consumed as a breakfast cereal served with cold milk, though it is commonly used in American baked goods and desserts. The cereal functions as a textural component in pie crusts, cookie recipes, puddings, and ice cream toppings, where its hardness and mild sweetness provide structural integrity and subtle flavor. It can be crushed coarsely for crust applications or used whole as a crunchy garnish. Some home cooks incorporate Grape-Nuts into bread and cake batters for added texture. The cereal is also consumed as a breakfast dish with hot milk or as a component of savory preparations, reflecting regional American comfort food traditions.
