Sencha literally means "roasted (煎) tea (茶)", however, the process by which sencha is created differs from Chinese green teas, which are initially pan-fired (and could probably therefore more accurately be called "roasted" teas). Japanese green tea is first steamed for between 15–45 seconds to prevent oxidization of the leaves. Then, the leaves are rolled, shaped, and dried. This step creates the customary thin cylindrical shape of the tea. Finally, after drying, the leaves are fired to aid in their preservation and to add flavour.
