Black tea was undoubtedly born in China, probably at the end of the 16th century. One usually speaks of the areas around the Wuyi Mountains in Fujian Province in the southeastern parts of the country. Exactly how it was invented is not known. According to the legends, it is, as so often, about a mistake. Someone happened to forget to heat the tea leaves and they then began to oxidize. Presumably the development was initially connected with oolong teas. However, what was of great importance for the spread both in the past and in recent years is its good export properties. Black tea is much more durable than green tea and was therefore better suited for the long transports.
