To answer the often asked question, "what is the decaffeinated coffee with the least caffeine", we need to split up the answer depending on the decaffeination process as follows:

  • Methylene Chloride Decaf Coffee Process
  • The CO2 "Sparkling Water" Decaf Coffee Process
  • The Swiss Water Decaf Coffee Process

In order of highest caffeine to lowest caffeine levels, the caffeine levels in these decaffeination processes are as follows:

Highest  Caffeine Level Decaf Process:

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.

Unknown Caffeine Level Decaf Process:

The CO2 Decaf Process caffeine content is not clear - we cannot find information on how much caffeine is in CO2 Process decaffeinated coffee.  Often called the "sparkling water" process, it uses CO2 to remove caffeine from green coffee beans instead of a chemical solvent.

Lowest Caffeine Level Decaf Process:

The Swiss Water Decaf Process is certified 99.9% caffeine free and uses only water (no chemicals) to decaffeinate the beans.
