To answer the often asked question, "how much caffeine is in decaffeinated coffee", we need to split up the answer depending on the decaffeination process as follows:
- The Swiss Water Decaffeination Process
- The CO2 "Sparkling Water" Decaffeination Process
- Methylene Chloride Decaffeination Process
The Swiss Water Decaf Process is certified 99.9% caffeine free and uses only water (no chemicals) to decaffeinate the beans.
The CO2 Decaf Process caffeine content is not clear - we cannot find information on how much caffeine is in CO2 Process decaffeinated coffee. The process uses CO2 to remove caffeine from green coffee beans instead of a chemical solvent.
The Methylene Chloride Decaf Process is decaffeinated to a 96-97% caffeine free level and is a process whereby a solvent called Methylene Chloride is used to remove the caffeine from coffee beans.
