Oolong tea origins

Oolong represents a true artisan mastership of tea processing. The look, shape and flavor of an oolong tea can differ wildly depending upon the region where it’s grown and how it’s processed. The origins of oolong are claimed in both china and taiwan and the tea is still extremely revered in both countries today.

One story claims that the chinese bestowed the name “wulong” or “black dragon” upon the big dark tea leaves, which were heavily oxidized and twisted into shapes that happened to resemble the mystical chinese dragon. Another story tells a tale of a tea farmer called wu liang (later reduced to wulong) who found the oolong style of tea by accident. The farmer was sidetracked after a long day of tea selecting and upon going back to his withering tea leaves he discovered they had currently begun to oxidize. No matter which story you believe, it holds true that the most popular chinese oolongs are grown in high mountainous regions over rocky terrain and in cool weather. It is the unique location and extreme environment that gives these oolongs the abundant flavor they are popular for.

Taiwan’s most well-known oolongs are generally less oxidized (10% to 40%) and therefore tend to be greener in color and lighter in taste than chinese oolongs. The styles of oolong produced across the country differ just as much as the designs of red wine that come out of france.
