Coffee production
Coffee production is the industrial process of converting the raw fruit (the coffee cherry) of the coffee plant into finished coffee beans. About eight months after coffee cherries appear on a coffee plant, the cherries are harvested either by hand or by machine. Then they are, depending on the method, pulped and then dried or simply set out to dry. After this, the beans are stripped of their remaining dry skin and fruit residue. Once they are cleaned, sorted, and graded, they are suitable for distribution. While all green coffee, produced from immature coffee beans, is processed, the method that is used to process coffee varies, and significantly affects the flavor of coffee once it is roasted and brewed. Coffee production is a major source of income for 12.5 million households, most in developing countries.
A coffee plant usually starts to produce flowers three to four years after it is planted, and it is from these flowers that the fruits of the plant (commonly known as coffee cherries) appear, with the first useful harvest possible around five years after planting. The cherries ripen around eight months after the emergence of the flower, by changing color from green to red, and it is at this time that they should be harvested. In most coffee-growing countries, there is one major harvest a year; though in countries like Colombia, where there are two flowerings a year, there is a main and secondary crop, the main one April to June and a smaller one in November to December.
In most countries, the coffee crop is picked by hand, a labor-intensive and difficult process, though in places like Brazil, where the landscape is relatively flat and the coffee fields are immense, the process has been mechanized. Whether picked by hand or by machine, all coffee is harvested in one of two ways:
All coffee fruit is removed from the tree, regardless of maturation state. This can either be done by machine or by hand. In the first method, pickers generally place a canvas on the ground. They then grab the branch next to the trunk with their hands and pull outward, knocking all of the fruit onto the ground. After doing this with all branches and trees for the length of the canvas, the pickers then collect the coffee in bags. This process can be facilitated through the use of mechanical strippers.
Only the ripe cherries are harvested and they are picked individually by hand. Pickers rotate among the trees every eight to ten days, choosing only the cherries which are at the peak of ripeness. It usually takes two to four 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. As of 2003[update], payment per basket is between US $1.00 to $10 with the overwhelming majority of the laborers receiving payment at the lower end. An experienced coffee picker can collect up to six or seven baskets a day. Depending on the grower, coffee pickers are sometimes specifically instructed to not pick green coffee berries since the seeds in the berries are not fully formed or mature. This discernment typically only occurs with growers who harvest for higher end/specialty coffee where the pickers are paid better for their labor.
Lots including unripe coffee fruit are often used to produce cheaper mass consumer coffee beans, which are characterized by a displeasingly bitter/astringent flavor and a sharp odor. Red berries, with their higher aromatic oil and lower organic acid content, are more fragrant, smooth, and mellow. As such, coffee picking is one of the most important stages in coffee production.
In the "wet process", the fruit covering the coffee beans is removed before they are dried. Coffee processed by the wet method is called wet processed or washed coffee. The wet method requires the use of specific equipment and substantial quantities of water.
