Oolong or Wulong (dark dragon) is one of China‚Äôs six categories or types of tea, like Lucha (green tea), Hongcha (red tea, i.e. black tea), Heicha (black tea, i.e. Pu-erh tea), etc. It was developed and perfected in the Wuyi (‚ÄúBohea‚Äù) mountains of Fujian Province during the last years of the Ming dynasty. Oolong tea falls between the green and black tea families, with degrees of oxidation ranging from 7 percent to 70 percent. China‚Äôs principal production areas include Minbei (North Fujian), Minnan (South Fujian), Guangdong, and Taiwan. A few Oolongs are also manufactured in India, Indonesia and Kenya.
