Coffee

Coffee is a generally consumed beverage prepared from the roasted seeds — usually referred to as beans — of the coffee plant. Though sometimes served cold, it is classically served hot. A typical 7 fluid ounce cup of coffee contains 80–140 milligrams of caffeine, depending on the bean and method of roasting and preparation.Some people drink coffee "black" (plain), others sweeten their coffee or add milk, cream or non-dairy creamer. Coffee represents 71% of all the caffeine consumption in the United States, followed by soft drinks and tea.Coffee, along with tea and water, is one of the the majority popular beverages world-wide, its volume amounting to about a third of that of tap water in North America and Europe.In 2003, coffee was the world's sixth largest agricultural export in value, behind wheat, maize, soybeans, palm oil and sugar.
