Coffee
trees measure 7 to 8 meters and are maintained in culture
to 2 meters. They provide drupes (cherries of coffee) to 2
cores, first green then red, of which each contains a seed:
the coffee bean. These are dried to air (coffee no washed)
washed either for the extraction of seeds (washed coffee),
roasted to a temperature of 200 then to 250°C. The country
of coffee origin is Yemen. Coffee is first consumed in Africa
like food, then as drink to the 15èmth century: the
Moslem world knows to this time a public coffee proliferation.
Europe familiarizes himself with coffee to the 17th century.
The 2 dominant species (on 50) are the ARABICA and the ROBUSTA.
The different tastes depend on the combination of species
and countries of origin (equatorial belt): 10 millions of
coffee hectares.
