Green Tea
Green tea is a type of tea that is made from Camellia sinensis leaves that have not undergone the same withering and oxidation process used to make oolong and black tea. Because leaves are unoxidized, green teas keep their vital color. To prevent oxidization, the leaves are heat processed to eliminate the enzyme responsible for oxidization. In China, this is generally done by roasting or pan-firing the leaves, while the Japanese generally accomplish this by steaming the leaves at a high temperature. Each process tends to bring out a more particular flavor from the tea leaves.
There are many different varieties of green tea in China, for example: BiLuoChun (named after the shape of the leaves, which are curled like snails), LongJing transl) ("Dragon Well" transl), Taiping Houkui and others.
For brewing generally use two grams of tea per 100 ml of water. Higher-quality teas use more tea leaves and are steeped multiple times for short durations. Steeping temperatures range from 61°C to 87°C and times from 30 seconds to three minutes.
