Coffee substitutes are non-coffee products, usually without caffeine, that are used to imitate coffee. Coffee substitutes can be used for medical, economic and religious reasons, or simply because coffee is not readily available. Roasted grain beverages are common substitutes for coffee. Some ingredients used include: almond, acorn, asparagus, malted barley, beechnut, beetroot, carrot, chicory root, corn, cottonseed, dandelion root, fig, boiled-down molasses, okra seed, pea, persimmon seed, potato peel, rye, sassafras pits, sweet potato, wheat bran. Ground roasted chicory root has been sold commercially on a large scale since around 1970, and it has become a mainstream product, both alone and mixed with real coffee. [Wikipedia]
