The earliest legend
The person who thought of the idea of brewing a drink from coffee beans is not known.
However, coffee drinking has been known in the Middle-East since long before our era.
Rhazes, an Arabic doctor, (approximately 900 BC) mentions coffee in one of his writings. A
far nicer story is that of the Arabic goatherd. Different versions are told but the basic
story remains the same.

Manufacturing process of coffee
Taste is a matter of personal preference, this is certainly true when it comes to
coffee. Coffee's characteristic flavour and aroma develop during the roasting process. The
flavour is locked within the green coffee bean until it is roasted. Heating green coffee
beans sets a series of complex chemical reactions in motion that release the flavour
compounds hidden within each bean. The coffee beans are usually ground after roasting, in
so-called rolling mills. A coffee bean can not be ground fine enough in one time to be
suitable for the modern filter systems.

The secrets about coffee brewing
When hot water comes into contact with ground coffee, the aroma, flavour and colour
constituents are released. Just how many of these components finally end up in the cup is
determined by the grind size, water quality and quantity and brewing temperature, as well
as the length of time the water is in contact with the ground coffee (brewing time).

World coffee trade
After petroleum, coffee is the world's most important traded commodity, standing above
coal, meat, wheat and sugar. The global harvest, however, is subject to considerable
fluctuations from year to year. These fluctuations are caused by a variety of factors.
Besides climate-induced fluctuations, both the amount of coffee produced and the price
charged for it are determined by the commercial policy interests of the producing and
purchasing countries. This explains why the total annual harvest figures tend to be
variable rather than constant.

Learn about decaffeinated coffee
Coffee naturally contains the active supplement caffeine. The stimulating power of
coffee is as well known as the outstanding taste. A lot of people appreciate this
stimulating power, but there are some people that do not handle caffeine so well or do not
like the stimulating effect every time of the day. For them there is decaffeinated coffee
on the market.
Normal coffee beans contain between 0.8 percent and 2.5 percent caffeine depending on
origin and variety. Decaffeinated coffee is not entirely caffeine-free. In European
Community (EC) countries, roasted decaffeinated coffee may contain a caffeine residue of
0.1 percent and coffee extract 0.3 percent.

Learn about instant coffee
To produce instant coffee, millions of cups of coffee a day are produced. These huge
amounts of fresh coffee are then concentrated by allowing a considerable amount of the
water to evaporate. The coffee produced is then made into instant coffee using one of the
two techniques: freeze-drying or spray-drying.
