The green coffee is soaked in water of around 80° C for about an hour. The caffeine dissolves into the water.
The coffee is then removed from the water and carbon is added to the water to remove the caffeine. After that the coffee is put back into the water to reabsorb the natural coffee bean aromas. The coffee beans are then dried and the usual grinding and roasting methods are employed.
The removal of caffeine is, therefore, completely natural. This decaffeination process removes up to 99.9% of the caffeine from the coffee beans.
