Green tea is made from the Camellia sinensis plant, the same plant species from which black teas are made. In the Chinese provinces of Fujian, Zhejiang and Anhui – the home of some of the best green teas – over a thousand different types of green tea are made, rivalling wine in diversity. Here, ancestral techniques vary from region to region, or even from village to village. Introduced to Japan in the eighth century by Buddhist monks, green tea has more recently spread to other tea-producing countries such as Vietnam and northern India.
