Coffee, cafe, Caffea arabica

Caffea is a genus consisting of over 90 species, 2 most common species are Caffea arabica and Caffea  canephora ( syn. Caffea robusta ). Coffee trees are natives of Ethiopia, where coffee beans were used since about 800 AD. Coffee as a drink started out in 15th century. In Europe, some of the first  coffee drinkers were  hardcore criminals since  the penalty for drinking coffee was death ( in Austria, during it's war with Turkey sometime in 16th century).
There are countless researches about health effects of coffee, both positive and negative. According to some legend, one of the medieval kings cancelled death penalty for some twins and made them drink  coffee and tea 3 times a day in their cells. They outlived the king and died sometime in their 70s, which was a very advanced age  for their time.
In 2009, 83 countries cultivated coffee and  8 342 736 tonnes of coffee  (green beans )were produced, a largest crop of coffee beans ever. That is 1 kg and 255 grams of green beans per capita.Roasting coffee makes it 10 to 25% lighter,  so it should be about 1 kg  or 2.2 pounds of roasted coffee per potential consumer per year.  So there is a cup of coffee for everybody out there, for every day of the year.Over the last 50 years , coffee bean production almost doubled, however  land usage did not increase significantly.  Still, over 6.35% of all permanent crop land in the world is used for coffee production, almost 10 million hectares. For Brazil, this number is 26.6%.
Biggest coffee producer is Brazil  with 2 440 060 tonnes as of 2009, biggest producer per capita is Colombia with  20.17 kg of coffee beans produced per capita. That is almost 47 grams of roasted coffee beans per day. Imagine that, a Colombian must  drink almost 7 cups of expresso per day to keep his national treasure at bay..

Average yield  of coffee beans was 847.7 kg per hectare in 2009, that is also the  highest yield ever ; lowest yield (since 1961) was in 1964, 384 kg per hectare. Individual record belongs to Tonga (1997)-- 3200 kg per hectare.

Prices , coffee robusta  ( with Vietnam as a largest producer/exporter) is about $2000-2100 per ton (about 1/3d of all coffee produced is robusta),  Coffee arabica is $2.51 per pound  in New York exchange market.
