Black tea is a completely fermented tea. Black tea is the most popular tea worldwide. And Chinese black tea is among the most popular one.

Black tea has a stronger flavor and much darker color than green tea. Leaves are first spread out to wither for many hours after plucking. The leaves are then rolled. The rolling stage begins the fermentation process, which turns the leaves into a copper color. After two to four hours, the leaves are heated to remove moisture and end the fermentation process.

The quality of black tea is determined by the origin, growing conditions, and manufacturing skill of the tea estate manager. All tea comes from tropical or subtropical climates. Tea plants will flourish where it is warm and where rainfall is heavy. However, while the plant grows best in hot climates, the best quality tea is made in the cooler climates at altitudes of 3,000 to 7,000 feet. The slower growth of the tea leaves at high altitudes produce more flavorful tea..

Many studies have indicated that black tea may possess some of the healthy properties associated with green tea, although the evidence is not as strong. More research is needed to determine black tea's role in human health.

The origin of Chinese black tea is Wuyi mountain of Fujian province. And the black tea from this area is extremely well known in the market for its good quality and reputation.
