About coffee

The Bean Belt
A coffee plant prefers rich soil and mild temperatures, with lots of rain and shaded sun. It grows best in a band around the middle of the world, bounded by the Tropics of Capricorn and Cancer, known as the Bean Belt. Soil, climate and altitude affect the flavor of the beans.

Red Cherry to Green Bean
What we call a coffee bean is actually the seeds of a cherry-like fruit. Coffee trees produce berries, called coffee cherries, that turn bright red when they are ripe and ready to pick.


Coffee seed types
There are two main species of the coffee plant, Coffea arabica being the older one. Coffee is thought to be indigenous to south-western Ethiopia, specifically from Kaffa, from which it may have acquired its name.[10] While more susceptible to disease, it is considered by most to taste better than the second species, Coffea canephora (robusta). Robusta, which contains about 40–50% more caffeine, can be cultivated in environments where arabica will not thrive and probably originated in Uganda.
