Coffee

Coffee is a widely consumed beverage prepared from the roasted seeds—commonly referred to as beans—of the coffee plant. It is usually served hot but can also be served cold. A typical 7 fluid ounce (ca. 207 mL) cup of coffee contains 80–140 milligrams of caffeine, depending on the method of preparation.[1] Some people drink coffee "black" (plain), while others sweeten their coffee, and/or add milk, cream or non-dairy creamer. Coffee represents 71% of all the United States caffeine consumption followed by soft drinks and tea.[2] Coffee, along with tea and water, is one of the most popular beverages world-wide, its volume amounting to about a third that of tap water in North America and Europe.[3] In 2003, coffee was the world's sixth largest agricultural export in terms of value, behind wheat, maize, soybeans, palm oil and sugar.[4]

The English word "coffee" is believed to be derived from the name of the place from which coffee originated, Kaffa, Ethiopia. Coffee's Arabic name, قهوة qahhwa, was borrowed by Ottoman Turkish as kahve, which in turn was borrowed into Italian as caffè and French as café.[5] Early forms date to as early as the last decade of the 16th century, but the word "coffee" itself did not come into use until the early to mid 1600s[6]
