First known discovery of coffee berries. Legend of goat herder Kaldi of Ethiopia who notices goats is friskier after eating red berries of a local shrub. Experiments with the berries himself and begins to feel happier. The coffee trees are cultivated on the Arabian Peninsula. Coffee is first roasted and boiled by Arabs making "qahwa" --- a beverage made from plants. The world's first coffee shop opens in Constantinople. It is followed by the establishment of two coffee houses in 1554.
Although it has a long shelf life, instant coffee quickly spoils if it is not kept dry. Instant coffee differs in make-up and taste to ground coffee. In particular, the percentage of caffeine in instant coffee is less, and bitter flavor components are more evident. The lowest quality coffee beans are often used in the production of instant coffee (the best beans are usually kept to be sold whole) and sometimes other unwanted residues from the harvest are used in the production process. Coffee contains the following: Trimethylphenol, ethylphenol, methoxy, ethylphenol, methylenephenol, dicaffeoyl, quinic acid, ethylphenol, methoxy, vinylphenol, acetaldehyde, caffeine, caffeol, caffeoyl, quinic acid, caffetannic acid, chlorogenic acid, citric acid, daturic acid, guaiacol, hypoxanthine, isochlorogenic acid, putrescine, scopoletin, spermidine, spermine, sugars, tannic acid, tannin, theobromine, theophylline, thiamin, trigonelline and xanthine.
Many of these compounds, like chlorogenic acids, will be destroyed by the roasting process, and many, will be oxidized to form new compounds not listed above. Most of these, like the phenolics at the top, are responsible for the aroma of the coffee, while others, like thexanthin derivatives give coffee its stimulant qualities. Coffee plants belong to the botanical genus Coffea in the family Rubiaceae, which has 500 genera and over 6,000 species. Although there is some disagreement, the number of species belonging to Coffea ranges from 25 to 100. Most commercial green coffee is either the C. Arabica or C. canephora species, which is referred to commercially as Arabica and Robusta, respectively. Coffea Arabica is an allotetraploid inbreeder (2n = 44). Forty to fifty cultivars (infraspecific taxa) are known, and are suspected to be derived from two cultivars of C. Arabica being var. arabica (including var. typica) and var. bourbon.
Coffee berries and their seeds undergo several processes before they become the familiar roasted coffee. First, coffee berries are picked, generally by hand. Then they are sorted by ripeness and color and the flesh of the berry is removed, usually by machine, and the seeds-usually called beans-are fermented to remove the slimy layer of musiclag still present on the bean. When the fermentation is finished, the beans are washed with large quantities of fresh water to remove the fermentation residue, which generates massive amounts of highly polluted coffee west water. Finally, the seeds are dried, sorted, and labeled as green coffee beans. A traditional way to let the coffee beans dry is to let them sit on a cement patio and rake over the beans till dry. Although some companies just use cylinders to pump in heated air and that will dry off the coffee beans.
At present, 85 percent of Americans begin their day by making some form of the drink, and the average American will consume three cups of it over the course of the day. - 16083
