Currently, about 25 types of coffee trees exist, the variation stemming from environmental factors such as soil, weather, and altitude. Some of them are coffea arabica, coffea benghalensis, coffea robusta, coffea congensis, coffea excelsa, coffea gallienii, coffea bonnieri, coffea mogeneti, coffea liberica, and coffea stenophylla etc. The seeds of different species produce coffee with slightly different characteristics. The two main species are coffea robusta and coffea arabica. Coffea arabica accounts for about 75% of the world's coffee trade. The robusta strain produces less expensive beans, largely because it can be grown under less ideal conditions than the arabica strain.
Coffee trees grow best in a temperate climate without frost or high temperatures. High altitude plantations located between 3,000 and 6,000 feet (914.4 and 1,828.8 meters) above sea level produce low-moisture beans with more flavor. Today, brazil produces about half of the world's coffee.
Cherries of the coffee plant are processed to obtain green coffee beans. The pulp of the cherry is removed leaving the seeds or beans, which is known as green coffee beans. It then dried.

It takes heat to spark the chemical reactions that turn carbohydrates and fats into aromatic oils, burn off moisture and carbon dioxide, and alternately break down and build up acids, unlocking the characteristic coffee flavor. One of these aromatic oils is caffeol, which is largely responsible for coffee's aroma and flavor.
