Green teas are generally described as ‘unoxidized’ teas and no
chemical change has occured during its manufacture. Processing
differs from country to country but the basic manufacture
sometimes involves a short period of withering to allow some of
the water content in the leaf to evaporate, then basket, pan firing,
or steaming is in order to de-enzyme the leaf. The diversity
in leaf appearance is often astounding, with needles, spheres,
pellets, curls and blades all possible. China and Japan are the
traditional producers.
