A wheat berry, or wheatberry, is a whole wheat kernel, composed of the bran, germ, and endosperm, without the husk. Botanically, it is a type of fruit called a caryopsis. Wheat berries are eaten as a grain, have a tan to reddish-brown color, and can vary in gluten and protein content from 6–9% ("soft") to 10–14% ("hard"). They are often added to salads or baked into bread to add a chewy texture. If wheat berries are milled, whole-wheat flour is produced. Wheat berries are similar to barley, rye, and kamut.
