Coffee is a major crop in Karnataka, India. The state is the second largest producer of coffee in India, after Kerala.

The climate in the Western Ghats is ideal for coffee cultivation, with cool temperatures and high rainfall.
Coffee is a shrub that is native to Africa. It was first cultivated in Ethiopia, and it was later introduced to India by the Portuguese. Coffee was first grown in Karnataka in the 17th century, and it has been a major crop in the state ever since.
Coffee is grown in the hills of Karnataka, at altitudes of 1,000 to 2,000 meters. The coffee beans are harvested from the coffee cherries, which are red berries that grow on the coffee plant. The coffee cherries are dried and then roasted, and the roasted beans are ground to make coffee powder.
