Coffee production years after planting for a coffee plant to produce coffee beans that are ripe enough to harvest. The plant eventually grows small white blossoms that drop and are replaced by green berries. These green berries will become a deep red color as they ripen. It takes about 9 months for the green cherries to reach their deepest red color. Because this kind of harvest is labor-intensive, and thus more costly, it is used primarily to harvest the finer arabica beans. The laborers who pick coffee by hand receive payment by the basketful. , payment per basket is between US$2.00 to
History of coffee group were the first to have recognized the energizing effect of the native coffee plant. Oromo tribesmen who consumed it were hunters who left on days-long treks and benefitted from the coffee plants ability to quell hunger and provide more energy. Studies of genetic diversity have been performed on "Coffea arabica" varieties, which were found to be of low diversity but with retention of some residual heterozygosity from ancestral materials, and closely related diploid species "Coffea canephora" and "C. liberica"; however, no direct evidence has ever been found indicating where in Africa coffee grew or who among the natives might
