What is black tea?

ANSWER

Black tea is made from the leaves of a bush called Camellia sinensis. A process called oxidation turns the leaves from green to a dark brownish-black color. Oxidation means the leaves are exposed to moist, oxygen-rich air.

Tea makers can control the amount of oxidation. Black tea is a fully oxidized tea. Green tea comes from the same plant, but isn't oxidized.
