Half of this coffee is decaffeinated using the Mountain Water Process (MWP).  MWP immerses the green coffee beans in the clear, pure water from the glaciers on the highest and most beautiful mountain in Mexico, the Pico de Orizaba or Citlaltepetl, to extract the caffeine. The water contains the soluble components of the flavor, so that, during the extraction of the caffeine, the beans maintain their original components. To separate the caffeine from water containing soluble components, the water passes through a special filter which removes the caffeine. This results in "flavor changed water" saturated with flavor components but free of caffeine, which is used again in the extraction process. 

This is all unflavored Socially and Environmentally Responsible Coffee (SERCtm).  Socially and Environmentally Responsible Coffee is a combination of being organically-grown, providing adequate shade and shelter to birds, and being purchased from the farming cooperatives at fair trade prices (25-45% above regular natural coffee prices).
