Growing conditions for coffee. |

Coffee has a long and varied history, but its thus far been traced back to originating in the mountains region of Abyssinia (current day Ethiopia) over 2,000 years ago. Technically a evergreen shrub, coffee belongs to the Rubiacea family, of which over 500 genera and 8,000 species exist. But of the many species, only two are of economic importance, those belonging to Coffea Arabica and Coffee Cenephora, or more commonly known as Robusta. Arabica accounts for roughly 75% of total world production, while C. Robusta the remaining 25%.
The majority of the coffee cultivated worldwide is concentrated within ten degrees north and south of the Equator in an area known as the ‘Coffee Belt’ (see below). Harvest season for those countries north of the Tropic of Cancer typically run between December to February, while those south of the Tropic of Cancer run from May to August.
Arabica being tropical in nature, require that the plant receive 1,200-2,200mm of rainfall per year and grown a ambient temperature of 15o-24oC. Depending on the species, coffee plants can grown to a height of 2.5-4.5 meters, though shrubs are typically pruned to 2-2.5m for easier harvesting. Robusta on the other hand slightly more rainfall (2200-3000mm/yr) and can grow up between 4.5-6.5m in height.
Typically three to four years after planting we begin to see the formation of delicate blossoms and the scent of jasmine permeate the air. The blossoming usually occur after several episodes of rainfall and last only three days to four days. After about six to nine months later, these blossoms become what is to become the tree's fruit (cherry).  The fruit begins as a green cherry which eventually ripens and changes to a deep red color at full maturation. These cherries are harvested and subsequently processed to transform what we call coffee today. Interestingly, a typical coffee plant will only produce one pound of roasted coffee in a full harvest year.
