Decaffeination this trait could be bred into other coffee plants by crossing them with "C. charrieriana", or an equivalent effect could be achieved by knocking out the gene for caffeine synthase in normal coffee plants. Tea may also be decaffeinated, usually by using processes analogous to the direct method or the CO process, as described above. The process of oxidizing tea leaves to create black tea ("red" in Chinese tea culture) or oolong tea leaves from green leaves does not affect the amount of caffeine in the tea, though tea-plant subspecies (i.e., "Camellia sinensis sinensis" vs. "Camellia sinensis assamica") may differ
Chinese tea be a light drink flavoured. However, when sipped as a daily beverage, Chinese people tend to use a special personal tea bottle, in which water is allowed to infuse with tea leaves for hours, and sipped continuously. This method, which is more prevalent in day to day Chinese life, involves the repeated use of the same tea leaves throughout the day. A traditional Chinese tea set consists of special clay or porcelain teapots, teacups, tea spoons, tea strainers, draining trays, tea forceps (for the leaves), a large forceps (for the tea cups) and occasionally, tea caddies. All of these are
