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
Tea tasting moving onto the next sample to taste. The flavour characteristics and indeed leaf colour, size and shape are graded using a specific language created by the tea industry to explain the overall quality. Generally speaking, once the quality has been tasted/graded, each tea company places a value on it based on market trends, availability and demand. Tea tasting Tea tasting is the process in which a trained taster determines the quality of a particular tea. Due to climatic conditions, topography, manufacturing process, and different clones of the "Camellia sinensis" plant (tea), the final product may have vastly differing flavours and
