Black
tea is more
oxidized than the
green,
oolong and
white varieties.All four varieties are made from leaves of
Camellia sinensis. Black tea is generally stronger in flavor and contains more
caffeine than the less
oxidized teas.In
Chinese and
culturally influenced languages, black tea is known as "red tea" (,
Mandarin Chinese hóngchá;
Japanese kōcha;
Korean hongcha), perhaps a more accurate description of the color of the liquid. The name black tea, however, could alternatively refer to the colour of the oxidized leaves. In Chinese, "black tea" is a commonly used classification for
post-fermented teas, such as
Pu-erh tea. However, in the Western world, "red tea" more commonly refers to
South African rooibos tisane.
