There are many sites which have a following story on their web
pages, a story which describe history of Earl Gray black tea:

"It is said that in 1830, an Englishman named Charles Earl Grey
traveled on a diplomatic mission to China, where in return for his
act of kindness, a local mandarin presented him with the recipe for
making this distinctive tea. A few corrections are in order.
Firstly, the Chinese have never been black tea drinkers, and were
unlikely to have a recipe for Earl Grey to bestow on visitors.
Secondly, Charles Earl Grey never set foot in China. Otherwise, the
story is completely true."


Keemun is a Chinese tea. A province of Yunnan is famous for its
black teas.
This is the first time I hear Chinese have never been black tea
drinkers.
If there is any true in it, does it mean a black tea is grown in
China mostly for export, and only younger generations enjoy the
black tea ?
