CO2 Decaf green tea, leaf, in foil bag, 8oz. This tea has it all: it's green, organic and decaf, to boot. Decaffeinated using the CO2 removal process, safe and saving the flavor and aroma. Great hot or iced. Steep 2-3 min. Best without milk. All our decaffeinated teas are decaffeinated using the CO2 removal process. This means that carbon-dioxide is applied at high pressure to the leaves to remove the caffeine. This is a naturally decaffeinated process, necessary if the product is to be labeled organic. Non-organic methods are using Methylene chloride or Ethyl acetate, which is the chemical way of decaffeination.
