Green tea skips the oxidizing step. It has a more delicate taste and is light green/golden in color retaining bitterness and astringency. Green tea, a staple in the Orient, is gaining popularity in the U.S. due in part to recent scientific studies linking green tea drinking with reduced cancer risk.The caffeine content is higher than black tea. It is also inferior to black tea in terms of aroma and flavour. The reason is the inactivation of enzymes during the steaming process. It is specially produced in Japan.
