three thousand years before that. According to an
Ancient Chinese legend, the emperor Shen Nong
Discovered tea when he was boiling drinking water
over an open fire. Some leaves from a nearby bush
fell into the water and remained there for some
time. The emperor noticed that the leaves in the
water produced a pleasant smell. Later he decided
to taste the hot mixture. It was quite delicious. And
in this way, one of the world’s favorite drinks was
invented.
