The Altura coffees are mostly coarse-grained, long and wide in shape. In the decaffeination process, the coffee is immersed in water in order to extract the caffeine. The water contains the soluble components of the coffee beans and during the extraction of the caffeine, the beans maintain their original components unaltered. To separate the caffeine from the water containing the soluble compounds, the water passes through a special carbon filter that removes the caffeine present. The result is a water full of aroma, rich in the flavor of the components but without caffeine, which is used again in the extraction process. The result of this process is a 99.9% caffeine-free coffee bean.
