Coffee is the most popular beverage in the world, Coffee has been consumed for more than 1,000 years, and today it is one of the most consumed drinks (more than 500 billion cups yearly) in the world.

The word “coffee” has originated from the Turkish word “KAUVEH” and the Arabic word “QAHWAH.” “KAUVEH or QAHWAH” means “infusion or beverage or wine or some type of wine” and is considered to be derivative of the herb root “qahiya,” which indicates having “no appetite” or causing no appetite or an appetite suppressant (www.en.wikipedia.org/wiki/ Coffee).

The most ancient manuscripts mentioning the culture of coffee date from 575 in Yemen, but only in the century XVI in Persia, the first coffee beans were toasted to be turned into the drink that we know today. Arabia was responsible for the coffee culture propagation.

According to legend, ancestors of today's Oromo people in a region of Kaffa in Ethiopia were elieved to have been the first to recognize the energizing effect of the coffee plant, though no direct vidence has been found indicating where in Africa coffee grew or who among the native populations might have used it as a stimulant or even known about it, earlier than the 17th century. The story of Kaldi, the 9th-century Ethiopian goatherd who discovered coffee when he noticed how excited his goats became after eating the beans from a coffee plant, did not appear in writing until 1671 and is probably apocryphal. Other accounts attribute the discovery of coffee to Sheikh Omar. According to an ancient chronicle (preserved in the Abd-Al-Kadir manuscript), Omar, who was known for his ability to cure the sick through prayer, was once exiled from Mocha in Yemen to a desert cave near Ousab (modern-day Wusab, about 90 km east of Zabid). Starving, Omar chewed berries from nearby shrubbery but found them to be bitter. He tried roasting the seeds to improve the flavor, but they became hard. He then tried boiling them to soften the seed, which resulted in a fragrant brown liquid. Upon drinking the liquid Omar was revitalized and sustained for days. As stories of this "miracle drug" reached Mocha, Omar was asked to return and was made a saint. From Ethiopia, the coffee plant was introduced into the Arab World through Egypt and Yemen.

Brazil, Vietnam, Colombia, and Indonesia are respectively the first, second, and third largest world producers, responsible for more than half of the world supply of coffee. According to the International Coffee Organization (ICO 2010), in 2009 Brazil produced approximately 40 million bags of coffee.

The coffee bean is the seed of the coffee plant or shrub (Coffea L.; family—Rubiaceae), with an average height of 5–10 meters; there are more than 70 species of this genera. The seeds are found inside red or purple fruit termed “cherry” or “berry.” Coffee cherries mostly contain two stones held together, but 10–15% of berries contain only a single seed, termed “peaberry.” It is believed that these have more flavor than the normal coffee beans [1].
