Coffee is the popular beverage name for a species of plants of Coffea genus cultivated for their beans that are used for preparing stimulating drinks. They are small evergreen shrubs with multiple stems and smooth leaves; bear green fruits that become crimson when ripe and normally contain two coffee seeds or beans. The trees can live for 20-30 years. Coffee primarily comes in allegiancemd two varieties, Arabian coffee (C.arabica) and Robusta coffee (C.cenephora) and originates from Africa. They grow in a wide range of soil but generally prefer deep, well draining loam with pH between 5 & 6.
Among the coffee producing countries India is the 6th largest producer and exporter of coffee in the world after Brazil, Vietnam, Columbia, Indonesia and Ethiopia with the state of Karnataka accounting for 71% production followed by Kerala at 21% and Tamil Nadu at 5% with an annual production of 8,200 tons. Both Arabica coffee and Robusta are produced in the proportion of 32:68. Indian coffee is unique because it is grown under the canopy of shady trees (a popular Agroforestry practice) making it one of the most eco-friendly crops in India that helps preserve the bio-diversity in the eco-sensitive Eastern and Western Ghats.
