An Accidental Invention
Did you know that tea, the most popular drink in the world (after water), was invented by accident Many people believe that tea was first drunk about 5,000 years ago. It is said a Chinese ruler called Shen Nong was the first to discover tea as a drink. One day Shen Nong was boiling drinking water over an open fire. Some leaves from a tea plant fell into the water and remained there for some time. It produced a nice smell so he tasted the brown water. It was quite delicious, and so, one of the world’s favorite drinks was invented.

It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries. In England, tea didn’t appear until around 1660, but in less than 100 years, it had become the national drink. The tea trade from China to Western countries took place in the 19th century. This helped to spread the popularity of tea and the tea plant to more places around the world. Even though many people now know about tea culture, the Chinese are without doubt the ones who best understand the nature of tea.
