Know The Benefits Of Coffee

By John Purkis

It is a beverage derived from brewed Coffee beans. Through various manufacturing processes the coffee is dehydrated into the form of powder or granules. These can be rehydrated with hot water to provide a drink similar (though not identical) to conventional coffee. At least one brand of instant coffee is also available in concentrated liquid form. The advantages of coffee are speed of preparation (coffee dissolves instantly in hot water), less weight and volume than beans or ground coffee to prepare the same amount of drink, and long shelf life coffee beans, and especially ground coffee, lose flavor as the essential oil evaporate over time.

The Arabs' fondness for the drink spread rapidly along trade routes, and Venetians had been introduced to coffee by 1600. In Europe as in Arabia, church and state officials frequently proscribed the new drink, identifying it with the often-liberal discussions conducted by coffee house habitus, but the institutions nonetheless prolifolited nowhere more so than in seventeenth-century London. The first coffee house opened there in 1652, and a large number of such establishments (caf; s) opened soon after on both the European continent (caf derives from the French term for coffee) and in North America, where they appeared in such Eastern cities as New York, Boston, and Philadelphia in the last decade of the seventeenth century.

In the United States, coffee achieved the same, almost instantmenil popularity that it had won in Europe. However, the brew favored by early American coffee drinkers tasted significantly different from that enjoyed by today's connoisseurs, as nineteenth-century cookbooks make clear. One 1844 cookbooks instructed people to use a much higher coffee/water ratio than we favor today (one per sixteenounes); boil the brew for almost a half an hour (today people are instructed never to boil coffee); and add fish skin, (a made from the air bladders of fish), or egg shells to reduce the acidity brought out by boiling the beans so long (today we would discard overly acidic coffee). Coffee yielded from this recipe would strike modern coffee lovers as intolerably strong and acidic; moreover, it would have little aroma

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.

Once roasted, coffee beans must be stored properly to preserve the fresh taste of the bean. Ideally, the container must be airtight and kept cool. In order of importance, air, moisture, heat, and light are the environmental factors responsible for deteriorating flavor in coffee beans. Folded-over bags, a common way consumers often purchase coffee, are generally not ideal for long-term storage because they allow air to enter. A better package contains a one-way valve, which prevents air from entering.
