The harvesting of coffee beans is a huge industry. Coffee is second only to oil as a worldwide commodity.
The variety of coffee beans is staggering, but they have classified into 2 main types the arabica and the robusta. The arabica gets it name from its original home, the Arabian Peninsula. The robusta is different because it has a high caffeine content.
By contrast to wine, the coffee berry (called a 'cherry') is not valued for its fruit, but only for the bean inside. It's that bean that is aged, roasted, ground and brewed to make the 400 million cups per day consumed around the world.
The beans come in two main varieties, green and red, with the latter - with its higher aromatic oil and lower acid content - used to produce the finer coffees. Hence one of the most important stages in the life cycle of bean to shelf is the picking.
Since most beans are hand picked by laborers, at the rate of a few baskets per day, separating the red and green is a valued skill and has a large effect on the final product.
After the fruit it is soaked and scoured to remove the beans from its center. After being removed the beans are cleaned to remove any excess fruit. The beans are then laid out on the ground to dry in the sun until almost all moisture from the bean is evaporated away.
Once dried the beans are separated. Some of this work is still done by hand, though machines are now more prevalent to do this part of the job. Once sorted, some beans are allowed to age from between 3 to 8 years, to be used later to make special types of coffees. Others are set aside to be roasted within the same year picked.
The oil that is contained within the beans gives them their unique flavor and aroma. This oil is released during the roasting process where the beans reach up to 400F and burst to release the inner flavor.
Once roasted the bags must be allowed to stand so that the carbon dioxide that they produce can dissipate. Roasting is done to different degrees to produce different flavors of coffees. Kenya and Java have a technique of lightly roasting their beans and this gives their coffee bean a unique flavor.
