Decaffeinated Teas: All of our decafs are processed using the Co2 Process. The advantage of this decaffeination process is that no chemical solvents are used to remove the caffeine. Instead, finished tea is briefly soaked in exceptionally pure water and gently flushed with CO2. The CO2 binds to the caffeine molecules and extracts them from the tea leaving behind all the natural proteins that give tea its flavor. It also leaves many of the polyphenols and antioxidants intact - so it's still good for you. Also, the origin distinct character of the tea is retained in the cup.
