All tea is processed from the same bush called Camellia Sinensis. White tea is tea made from new growth buds and young leaves of the plant. Green Tea is processed by steaming or pan firing the leaves to inactivate oxidation, and then are dried and sorted. Black Teas go through a slightly different process; the tea leaves are dried and gently pressed to expose the juices inside the leaf to oxygen, and then are oxidized for a specific period of time. Often times this process is called “fermentation” in the tea industry. The fourth type of tea, which is oolong, goes through the same process as black tea, but it is only oxidized for half the time.
