This method uses two natural elements, pure water and carbon dioxide ( together they make "Sparkling Water") to extract caffeine from the coffee grains. This method was discovered by Kurt Zosel, a well named scientific of the Max Plank Institute.

Steps for the Co2 or Carbonated Water Method:

• Coffee is mixed with pure water.
• When the coffee absorbs the water the beans expand, their pores open and release caffeine molecules.
• Now carbon dioxide which is 100% Natural Element is added to the pure water at 100 atmospheres pressure.
• Water and Carbon Dioxide (Co2) are mixed to create sparkling water.
• The carbon dioxide attracts caffeine molecules that are released.
• The captured caffeine is removed.
• Carbon dioxide does not touch the proteins and carbohydrates.
• The carbohydrates and the proteins are compounds that give coffee its distinctive smell and flavour.
• When the carbon dioxide has removed the caffeine the seeds are dried naturally.

Benefits of this method:

• Extracts Caffeine, effectively. Is a direct contact method but does not use chemicals.
• Proteins and carbohydrates do not chemically affect the coffee beans.
• The byproducts are natural and a 100% recyclable.
