Oolong represents a true artisan mastership of tea processing. The appearance, shape and flavor of an oolong tea can vary wildly depending on the region where it’s grown and how it’s processed.

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 occurred to look like the magical chinese dragon. Another story informs a tale of a tea farmer named wu liang (later shortened to wulong) who discovered the oolong style of tea by mishap. The farmer was sidetracked after a long day of tea picking and upon returning to his withering tea leaves he found they had currently begun to oxidize. No matter which story you believe, it is true that the most well-known chinese oolongs are grown in high mountainous regions over rocky surface and in cool weather. It is the distinct geography and harsh environment that offers these oolongs the abundant flavor they are well-known for.

Taiwan’s most famous oolongs are traditionally less oxidized (10% to 40%) and for that reason tend to be greener in color and lighter in taste than chinese oolongs. The designs of oolong produced throughout the nation vary just as much as the designs of wine that come out of france.

Some grow in remote mist-covered mountains, while others prosper in temperate bamboo-forested foothills. Some are plucked in spring for a flowery herbaceous taste, while others are picked in winter season and roasted for a hearty woodsy taste.
