During the eighteenth century, Europeans introduced coffee cultivation in many tropical countries as an export crop to meet European demand. In the nineteenth century, demand in Europe often exceeded supply, which encouraged the use of different substitutes with a similar flavor, like chicory root (buy organic coffee online). The main coffee producing regions are South America (particularly Brazil and Colombia), Vietnam, Kenya and Ivory Coast.
Freshly picked beans are processed either by the dry method or the wet and should be treated the same day of their harvest to risk of fermentation. When the basket is full, they use some sacks transported to the area. Another way of collecting is scraped or stripped from the branch of the coffee plant, which starts all fruit, regardless of their maturity, so they should be selected carefully harvest time so as to maximize the amount of fruit in their point.
Although still widely debated, it is believed that certain types of green beans improve with age; especially those valued for their low acidity, such as variants from Indonesia or India. Several producers sell beans aged about 3 years, and some even manage to sell 8-year variants. However, most experts agree that the best flavor and freshness is achieved one year after harvest, since coffee-beans aged in excess lose much of its essential oils.
The seed of coffee containing 2% caffeine. Already in 1943 it was found that one gram daily of caffeine (equivalent to 10 cups of espresso or 5 drip coffee filter), absorbed for a week is enough to induce a deficiency picture or withdrawal. Decaffeination is a process whose goal is to provide the taste, but without the stimulating effects of caffeine.
In Brazil, it is estimated that there are about 220,000 coffee plantations that give work to more than 3.5 million people. A young coffee tree needs three to four years to start producing fruit, with the highest productivity at six or eight. Then the tree can live many decades, but it is commercially viable only until twenty or thirty years.
Most of the green variants in the world goes through some sort of process of washing, including most of the top quality beans. The wet process requires a large amount of water and can cause serious pollution. Most are recycleable to save water flow, and, in doing so, the enzyme content in the water to the pulping process is concentrated, and this facilitates the fermentation. The water used for the final wash can be poured directly into rivers, but must go through another tributary wells filtration.
The decline of caffeine content is at the expense of taste qualities. Various methods are used. The general principle, based on the Roselius, is to soak the beans in water to extract caffeine from the liquid thus obtained by the addition of organic solvent or by adsorption on activated charcoal.
Then, the workers labor to remove the thin silver layer (integument) and vellum, producing clean green grain is traded internationally. The shells are recovered and used as fuel. They are washed then husked before leaving for the markets. The semi-wet is a hybrid with a very limited use process in Brazil, Costa Rica and Sumatara / Celebes. Cherry is passed through a rake to remove the skin and part of the flesh and the wet process but the resulting product is dried by sun and not fermented or brushing.
