Coffee is a soft commodity derived from a plant that grows mostly in subtropical and tropical climates. The beverage produced from the cherries on these plants is a primary source of caffeine in diets in both emerging and developed countries. Coffee is such an important dietary staple across the world that it has spawned a staggeringly large economy of its own. Coffee roasters, packers, growers, marketers and coffee equipment manufacturers depend on the commodity as do dairy producers and restaurant operators. Coffee commodity prices, therefore, play a vital role in the global economy.
