The presence of green fruits produce a more acidic coffee, but this can be avoided if these fruits are separately gathered. In Brazil and Hawaii mechanized harvesting is mainly based on the branches to vibrate. Once harvested the fruit, also called coffee cherry must be processed in order to remove pulp and mucilage and get the grain coated parchment, called 'parchment' or 'green' buy organic coffee online.
The plant was introduced in Europe, coming from the port of Mocha, in what is now known as Yemen. To import the beans to Europe, they were on boats on a long drive round the African continent. These long trips and exposure to sea air changed the flavor. Once the Suez Canal was opened, the journey time was greatly reduced to Europe and began to get coffee whose taste has not been altered. To some extent, this fresher product was rejected because Europeans were accustomed to the previous flavor.
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.
After drying or washing, the bean is still locked in the core of a fruit (endocarp) is coffee coke (after drying) or coffee or vellum patch (after washing). Need to sort, in order to remove any broken bean, discolored or damaged. The selection can be machined, in industrial facilities, using CCD cameras, but this operation is often done manually in developing countries. The commodity can be kept protected by the shells for a certain time. Some even older vintages to improve the taste. The last preparation step, giving the green variant its flavor is mechanically hulled grains.
And finally re-soak the beans in depleted liquid caffeine to reabsorb the other compounds always present. The solvent, ethyl acetate mainly found in the fruits, is never in contact with the grains, with only the water with which the grain is soaked. There is also a method that uses a jet descafeinamiento carbon dioxide under pressure.
