Green tea is plucked, withered, and rolled and then either roasted (in something resembling a giant wok) or steamed like your veggies (in a big cylinder); this heats the leaves, preventing fermentation and sealing in that lovely greenness. Steamed green teas tend to have a more delicate taste than the roasted version.
