The history of Taiwanese Oolong tea
In the early 1800's a Fujian tea merchant took some seeds to Taiwan to see how well the plants would grow there. It proved to be very successful and so in the following years tea production in Taiwan became very widespread. However for the first half of the century most of the tea was sent back to Fujian to be processed there. This changed in 1868 when a British man named John Dodd decided this was hugely inefficient, and so hired some Fujian tea masters to setup tea processing in Taipai. This worked out very well, and in the following year Dodd shipped 127 tonnes of what was then called Formosa tea to the United States, where it was a great success. From that time on, Oolong tea has been the most widely exported type of tea from Taiwan.
