White tea is tea manufactured by a process that uses relatively low heat and no rolling. The formative stage is an extended period of withering, during which enzymatic reactions progress under the right temperature, humidity and airflow. The key is to get the fresh leaves to mature properly with minimal oxidation. White tea usually contains buds and young tea leaves, which have been found to contain lower levels of caffeine than older leaves, suggesting that the caffeine content of some white teas may be slightly lower than that of green teas. White tea is a specialty of the Chinese province Fujian.

The leaves come from a number of varieties of tea cultivars. The most popular are Da Bai (Large White), Xiao Bai (Small White), Narcissus and Chaicha bushes. According to the different standards of picking and selection, white teas can be classified into a number of grades, further described in the varieties section.
