Green Tea is made from the leaves of the Camellia Sinensis plant. Unlike black teas, the leaves do not undergo an oxidation process. Instead, the leaves are heated soon after picking to remove moisture and prevent further chemical reaction. This results in a green leaf with a fresh taste. Most Japanese green teas are heated by steaming which results in a vegetative or "grassy" flavour and a bright yellow cup. Chinese green teas are pan-fried and take on a slightly toasty and sometimes smoky flavour, and a softer yellow cup.
