Green tea started the buzz for the health benefits of tea. Typically, green tea undergoes a multi-step process of steaming, pan-firing, and/or rolling before being dried to stop the oxidation process. Little oxidation occurs in most green teas, so they're differentiated from white teas mainly by the extra steps of processing the leaf before drying. Green teas reportedly contain the second highest concentration of antioxidants, which can neutralize dangerous free radicals in the body. The flavor of green tea ranges from grassy to sweet and has a mild astringency.
