The ancestor of black tea was in China. The earliest black tea in the world was invented by tea farmers in Wuyishan tea area of Fujian in the Ming Dynasty in China, and it was named "Zhengshan Seed". The Jiang family in Wuyishan village is a small-scale tea family that produces black tea in Zhengshan, with a history of more than 400 years.

Zhengshan small black tea was introduced to Europe in 16 10. 1662, when Portuguese princess Catherine married the king of charles ii, there were several boxes of small black tea from China in her dowry. Since then, black tea has been brought into the British court, and drinking black tea has quickly become an indispensable part of British royal life.

The early tea market in London, England, only sold small black tea from Zhengshan, which was extremely expensive. Only wealthy families can drink it, and Zhengshan small black tea has become an indispensable drink in British upper class. British people love black tea so much that they gradually turn drinking black tea into a noble and colorful black tea culture and spread it all over the world.

1689, Britain set up a base in Xiamen, Fujian, China, and bought a lot of China tea. Britain drinks more black tea than green tea and has developed its own unique black tea culture, all of which are related to the above historical events. Because all the teas bought in Xiamen are semi-fermented black tea-"Wuyi tea", a large number of Wuyi tea flowed into Britain, replacing the original green tea market, and soon became the mainstream of western European tea.

Wuyi tea is black, so it is called "black tea". Later, tea scientists classified tea according to its production methods and characteristics. The red soup and red leaves of Wuyi tea belong to' black tea' according to their nature. But the English idiom "black tea" was inherited to refer to "black tea".
