The six major tea categories in China refer to the classification of Chinese tea into six types: black tea, green tea, oolong tea, yellow tea, dark tea, and white tea.
This classification is based on the processing techniques and oxidation levels of the tea, rather than the tea plant varieties. However, each tea category has its optimal growing regions. For example, Longjing tea, a type of green tea, is best when made from tea leaves grown in the traditional tea gardens around West Lake in Hangzhou, known as West Lake Longjing, which is considered the finest among all Longjing teas.
Black Tea: 
Named for its reddish color in the dry leaves, brewed liquor, and leaf base, black tea is characterized by its red leaves, red liquor, and sweet, mellow flavor. Major Chinese black teas include Fujian’s Lapsang Souchong, Zhenghe Gongfu, and Keemun.
Green Tea: 
Named for its green color in the dry leaves, brewed liquor, and leaf base, green tea is one of China’s most important tea categories. Regular consumption of green tea can help prevent cancer, reduce fat, and aid in weight loss, while also mitigating the effects of nicotine for smokers. Major Chinese green teas include West Lake Longjing and Dongting Biluochun.
Oolong Tea:
With a wide variety, oolong tea is a uniquely Chinese tea category. It is made through a process that includes withering, shaking, pan-firing, rolling, and roasting, and was first developed around 1725 (during the reign of the Yongzheng Emperor of the Qing Dynasty). Oolong tea leaves leave a lingering fragrance in the mouth and a sweet, mellow aftertaste. Major Chinese oolong teas include Anxi Tieguanyin and Fenghuang Shuixian.
Yellow Tea:
Classified according to the tenderness and size of the fresh leaves into yellow bud tea, small yellow tea, and large yellow tea. Major yellow bud teas include Junshan Yinzhen and Mengding Huangya.
Dark Tea (Dark Tea): 
Named for its dark appearance, dark tea is a post-fermented tea, primarily produced in Yunnan, Guangxi, and Hunan. Traditional dark tea uses mature black tea leaves as raw materials and is a key ingredient in compressed tea. Major Chinese dark teas include Yunnan Pu’er tea, Guangxi Liubao tea, and Hunan Anhua tea.
White Tea (White Tea):
A minimally oxidized tea, white tea is a traditional Chinese tea crafted by the tea farmers. After picking, the leaves undergo only withering and drying, without pan-firing or rolling. White tea is characterized by intact buds covered in fine white down, a fresh and delicate aroma, a clear yellow-green liquor, and a light, sweet aftertaste. The most famous white tea is Fuding white tea from Fujian.
Each of the six tea categories has its own distinct characteristics:
- Green Tea (Unoxidized) is best consumed in spring and summer for its refreshing and invigorating properties;
- Yellow Tea (Lightly Oxidized) and White Tea (Minimally Oxidized) are mild in nature, suitable for those with digestive issues or those needing liver protection;
- Black Tea (Fully Oxidized) and Oolong Tea (Partially Oxidized) have a bright red liquor and rich aroma, ideal for autumn, winter, or iced consumption;
- Dark Tea (Post-Fermented) improves with age and is often stored for long periods, commonly used for lipid reduction and digestive support.
