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
Taiwanese tea Taiwan Tea TTES #18 is a cultivar developed by the Taiwan Tea Research and Experiment Station during the 1990s. The now popular tea is a hybrid of "Camellia sinensis" v. assamica and a native variety ("Camellia sinensis forma formosensis"), and is said to have notes of Honey, cinnamon, and mint. The tea's natural sweetness is a result of the fostered relationship with insects. The native Leafhopper (Jacobiasca formosana) spends its time throughout the growing season laying eggs and biting the tea plant, which causes the plant to produce two compounds, monoterpene diol and hotrienol. This defense mechanism, intended to attract
