Green Tea is slightly processed  and the oxidation process is halted by either  steaming or firing  the leaves. They are then rolled and dried .  As the tea is unoxidized, the tea contains antioxidants and polyphenols.  This tea has a  sweet vegetal flavour and herbal aroma.  

Darjeeling green tea is  becoming very  popular and is produced by many tea gardens in Darjeeling.  Since the Darjeeling green tea is  steamed to stop oxidation before it starts,  most of the polyphenols are preserved  and the  Darjeeling green tea variant has about 60% more polyphenol content than other black teas
