Our decafs are decaffeinated using an all-water method by Descafeinadores Mexicanos in Veracruz, Mexico. The exact process is a closely-held secret, but here are the basics. Unroasted green coffee is soaked in water. Caffeine and flavor components dissolve into this water, which is then filtered through a special charcoal filter. The filter traps the caffeine molecules while allowing the flavor components to flow through. This flavor-rich water is then recombined with the green coffee from which 97% of the caffeine has been removed.
