What is Cereal coffee?

A cereal coffee is a hot drink made from one or more cereal grains roasted and commercially processed into crystal or powder form to be reconstituted later in hot water. The product is often marketed as a caffeine-free alternative to coffee and tea, or in other cases where those drinks are scarce or expensive.

Several well-known cereal coffee brands are Nestlé Caro, Postum, and Inka. Other brands can be found at health food stores and at some grocery stores. Some common ingredients include toasted barley, malted barley, rye, chicory, molasses, and beet root.
