Sugar Cane Decaf
Sugar cane is a natural decaffeination process whereby the molasses derived from sugar cane (a readily available product in Colombia) is fermented to create ethanol. This alcohol is then mixed with acetic acid, to create the compound ethyl acetate.
The coffee is first submitted to an environment of water and steam in order to increase moisture content which is important in facilitating the extraction of caffeine from the beans. They are then washed in the sugar cane ethanol which dissolves the caffeine and dried to their original moisture content.
