coffee

Coffee is a tropical plantation crop of the genus Coffea (family Rubiaceae), of which two species dominate global commerce: Coffea arabica (Arabica), accounting for roughly 60 per cent of world output and prized for flavour, and Coffea canephora (Robusta), hardier, higher in caffeine, and resistant to leaf rust. The plant is believed to have originated in the Ethiopian highlands (Kaffa province, the probable etymological root), spreading through Yemen and the Arab world before Dutch and later European colonial planters carried it to Java, Ceylon, the Caribbean and Latin America. In India, legend credits the Sufi saint Baba Budan, who is said to have smuggled seven beans from Mocha (Yemen) around 1600 and planted them in the Baba Budan Giri hills of Chikmagalur, Karnataka — still the cradle of Indian coffee cultivation.

Coffee is a typical plantation crop requiring specific geographical conditions: warm temperatures between 15°C and 28°C, well-distributed rainfall of 150–250 cm, the absence of frost and strong sunlight, and shade — hence it is often grown under a canopy of trees on hill slopes between 600 and 1,600 metres. Arabica is grown at higher, cooler elevations while Robusta tolerates lower altitudes and warmer conditions. Well-drained, friable, humus-rich loamy soils, particularly the red and lateritic soils of the Western Ghats, are ideal; stagnant water is harmful. Cultivation is labour-intensive, involving nursery raising, transplanting, regular pruning, shade management and selective hand-picking of berries, followed by either the dry (natural) or wet (washed) method of processing to extract the bean.

In India, coffee is overwhelmingly a crop of the southern states. Karnataka is by far the largest producer (over 70 per cent of national output), followed by Kerala and Tamil Nadu, with emerging non-traditional cultivation in Andhra Pradesh, Odisha and the North-Eastern states. The sector is regulated by the Coffee Board of India (established under the Coffee Act, 1942, headquartered in Bengaluru), which promotes research, quality and exports. India is the world's seventh-largest producer and exports the majority of its output, with branded Indian specialities such as Monsooned Malabar and registered Geographical Indications including Coorg Arabica, Wayanad Robusta, Chikmagalur Arabica, Araku Valley and Bababudangiris Arabica coffees. Globally, Brazil remains the dominant producer, followed by Vietnam (the largest Robusta grower), Colombia, Indonesia and Ethiopia; as of 2026 climate stress, leaf rust and the borer pest threaten Arabica zones, fuelling interest in resilient varietals.

For UPSC and allied examinations, coffee is tested mainly in Geography (Prelims and GS Paper I) under agriculture and plantation crops, and in economic geography on cash-crop distribution and trade. Typical question angles include matching crops to ideal climatic and soil conditions, identifying the leading producing state (Karnataka), associating coffee with the Baba Budan hills and Western Ghats, distinguishing Arabica from Robusta, naming the regulatory Coffee Board, and recalling GI-tagged coffees. Map-based and statement-correctness questions frequently pair coffee with tea and spices as Western Ghats plantation crops, so candidates should master its precise geographical requirements and regional concentration.
