Want To Know More About 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.

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.

Many people take exception to neighbors cats using their garden or yard as a toilet, a mixture of used coffee grounds and & orange peel put round plants and in beds you want left alone will provide a pungent smell that cats do not like and so will find someone else's garden to use. To get rid of ants put used coffee grounds onto the ant hills, this will have to be done for each hill as the pesky things will move to another home. Kitchen drains tend to get smelly, simply get a cup of coffee grounds and tip down the plughole making sure you tip a kettle of boiling water down slowly & leave to work on the odors. For a quick fix on fabrics soak garment in strong black un-sugared coffee, this is an inexpensive way to dye clothes brown in an emergency but remember it will not be color fast. Coffee grounds can be used to clean any stain resistant surface; it has a mild & gentle abrasive element & smells fresh too, particularly good for smelly ashtrays and greasy surfaces.

To help plants to flourish add coffee to your soil, this is best done in small amounts of soil so you can add 1 cup of lime to balance acidity if need be, another way is to empty it straight onto your compost pile with other kitchen waste. - 16651
