The coffee bean belt is is that part of the world that is ideal for cultivating coffee. It is located 23.5 degrees north and south of the equator and passed through countries that have tropical climates.
In this region, the countries that are coffee producers include the Asia Pacific (China, India, Indonesia, Laos, Nepal, Papua New Guinea, the Philippines, Thailand, Vietnam), Africa (Burundi, Ethiopia, Kenya, Rwanda, Malawi, Tanzania, Uganda, Zambia, Democratic Republic of Congo) and Central and South America (Brazil, Colombia, Costa Rica, Cuba, the Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Jamaica, Mexico, Nicaragua, Panama, Paraguay, Peru, Hawaii, Puerto Rico, Venezuela).
Coffee beans grow in tropical climates. Ideally, the climate would have relatively warm days with year-round temperatures of 21° to 29 °C.
The coffee trees would need abundant rainfall of around 100 to 200 cm annually. Many coffee growers depend heavily on rainfall for their water supply, so it is important that the area would have a rainy season that would supply enough water for the coffee trees.
Coffee flourishes best in fertile volcanic soil or thick sandy clay. The Pacific Ring of Fire has the quality of soil that is ideal for coffee trees since there is a lot of volcanic action in these areas.
Ideally, coffee is grown on mountain slopes since water stagnation is very harmful for coffee plants so they are best grown on slopes. For the liberica and excelsa plants, lower altitudes between 300 to 400 meters above sea level is ideal, while arabica plants require higher elevation of around 1,000 to 2,000 meters above sea level. Robusta plants are able to thrive at any altitude.
