was discovered in 2008 in Cameroon, natural coffee plant that produces coffee without caffeine. The grains of this plant could be used for all natural decaf. Belongs to the family Rubiaceae, like normal coffee plant (Coffea arabica mainly). It is named in honor of Professor André Charrier, who made numerous studies on coffee for over 30 years.

The industrial process used to extract caffeine from coffee beans can not obtain a fully decaffeinated coffee, often left a residue of 2-3% caffeine. That is, decaffeinated coffee is not caffeine free.
Fact: Caffeine is a natural alkaloid, xanthine group, which appears on coffee, tea, mate, guarana, kola nut, cocoa and cocoa products like chocolate. Tea leaves contain more caffeine than coffee. However, the amount used to prepare a tea is much smaller than that used for coffee. Therefore, an infusion of tea contains less caffeine than a cup of coffee. And in the area, the green contains less caffeine than black.
