Chinese tea may be classified into five categories according to the different methods by which it is processed.

1)     Green tea: Green tea is the variety that keeps the original color of the tealeaves without fermentation during processing. This category consists mainly of Longjing tea of Zhejiang Province, Maofeng of Huangshan Mountain in Anhui Province and Biluochun produced in Jiangsu.        

Green Tea is the most natural of all Chinese tea classes. It's picked, natural dried, and then fried briefly (a process called "killing the green") to get rid of its grassy smell. Green Tea has the most medical value and the least caffeine content of all Chinese tea classes. Aroma is medium to high, flavor is light to medium. About 50% of China's teas are Green tea.

2)     Black tea: Black tea, known as "red tea" in China, is the category which is fermented before baking; it is a later variety developed on the basis of the green tea. The best brands of black tea are Qihong of Anhui, Dianhong of Yunnan, Suhong of Jiangsu, Chuanhong of Sichuan and Huhong of Hunan.        

Chinese Black tea produces a full-bodies amber when brewed. Black tea undergoes withering (drying), left to ferment for a long while, and then roasted. Black tea leaves become completely oxidized after processing. Black tea has a robust taste with a mild aroma. It contains the highest amount of caffeine in Chinese tea classes.

3)     Oolong tea: This represents a variety half way between the green and the black teas, being made after partial fermentation. It is a specialty from the provinces on China's southeast coast: Fujian, Guangdong and Taiwan.       

Typical Oolong Tea leaves are green in the middle and red on the edges as a result of the process to soften tealeaves. Oolong Tea leaves are withered and spread before undergoing a brief fermentation process. Then Oolong Tea is fried, rolled and roasted. Oolong Tea is the chosen tea for the famous Kung Fu Cha brewing process. It's the serious Chinese tea drinker's tea. Aroma ranges from light to medium. Beginners in Oolong Tea should be careful as even though flavor is only mild to medium, the tea could be very strong.

4)Compressed tea: This is the kind of tea that is compressed and hardened into a certain shape. It is good for transport and storage and is mainly supplied to the ethnic minorities living in the border areas of the country. Most of the compressed tea is in the form of bricks; it is, therefore, generally called "brick tea", though it is sometimes also in the form of cakes and bowls. It is mainly produced in Hubei, Hunan, Sichuan and Yunnan provinces.

Most Chinese Compressed Tea uses Black Tea as base tea. Compressed Tea has all the characteristics of Black Tea. It can be stored for years and decades. Aged Compressed Tea has a tamed flavor that Compressed Tea fans would pay huge price for.

5)     Scented Tea: This kind of tea is made by mixing fragrant flowers in the tealeaves in the course of processing. The flowers commonly used for this purpose are jasmine and magnolia among others. Jasmine tea is a well-known favorite with the northerners of China and with a growing number of foreigners.    

It is subdivided into Flower Tea and Scented Tea. Flower Tea is a simple concept that dried flowers are used, without much processing, to make tea. Scented Tea uses green tea, red tea as base and mix with scent of flowers. Chinese Scented Tea has light to medium flavor and medium to strong aroma.
