Origin of Oolong Tea / Wulong Tea / Wu-long Tea
It is said that Oolong tea first began to be produced at Mt. Wu Yi Shan in Fujian Province at the end of the Ming Dynasty about 400 years ago. Legend has it that the first cultivator of the tea was named Wu Liang. One day, Wu Liang went home after he had picked several pounds of mountain tea and caught a river deer. In the evening, he was busy with killing the river deer, and didn't have enough time to dry the green tea. The next day, he found the tea in the basket had fermented on the way back and after having been stored in the basket the whole night. He fried the tea at once. To his surprise, he found that the tea tasted very mellow, with no bitter and astringent taste. Soon Wu Liang taught his fellow villagers how to make the tea. Almost everyone in his village liked the fermented tea and they named it Wu Liang tea. In the south Fujian dialect, liang and long are two homophonic words. As time went by the tea was called Wulong tea by later generations in China, and Oolong in foreign countries.
Processing Oolong Tea / Wulong Tea / Wu-long Tea
After Oolong Tea / Wulong Tea / Wu-long Tea leaves are picked, they are left to wither for several hours (usually 8 - 24 hours). The next stage is rolling the tea leaves. Sometimes instead of rolling, shaking is done to bruise the outer edges of the leaves. After the leaves are rolled, oils from the leaves are brought to the surface. These aromatic oils aid in the oxidation process, which last for several hours. Once the veins become clear and the edges of the leaves become reddish brown, while the center remains green, the oxidation process is stopped by firing. For oolong tea, the leaves are heated at a higher temperature (higher than 200 degrees Fahrenheit) so that they can be kept longer, due to the lower resulting water content. After that, a final drying takes place. From there, it goes off to be sorted, graded, and packaged.
