More on The Wide World of Tea

As stated before, green and black teas differ in their processing. According to research conducted by the Tea Advisory Panel, the processing of green and black teas change their makeup.


Green Tea (Unoxidized): Short Withering, Usually by Sun-drying → Steaming/Parching, to Stop Any Further Oxidation → Flattening, Rolling, or Twisting → Drying, Usually in a Large Wok Over Low Heat → Final Firing, to “Cook Out” any remaining moisture and Stop Oxidation
