Literally, tea is the most consumed beverage after water worldwide. It is consumed hot in the East and cold with iced tea or hot with milk in the West. Black tea is a well-known variety of tea and is consumed regularly in Western and South Asian countries such as India and Sri Lanka.

Black tea is usually served without milk. It is prepared from tea plant which is scientifically called Camellia sinensis. The oxidation level provides the unique flavor and color ranging from amber to dark brown which tastes savory to sweet. The tea is more oxidized in comparison to green, oolong and white teas. It has stronger flavor. An oxidation process turns leaves from green to dark brownish to black color. Oxidation refers to expose leaves to moist and oxygen rich air. These four types of tea are made from same leaves of shrub Camellia sinensis. Small leaved Chinese variety plant and large leaved Assamese plant are the two predominant varieties used. Traditionally large leaved Assamese plant is used for black tea but in these recent years, it is used to produce some green and white teas.

In Chinese language, black tea is known as red tea which describes the color of liquid. However, the English term black tea indicates the color of oxidized leaves. Green tea loses its flavor within a year but Black tea is able to retain its flavor for several years. Due to this fact, it is used as an article of trade. The compressed bricks of Black tea are used as a form of de facto currency in Mongolia, Siberia and Tibet in 19th century. Recently green tea has got popularity due to its health benefits; still black tea covers ninety percent of tea sold in the West.

In Canada, blended Black tea is a combination of two or more black teas of leaves as well as buds of Camellia sinensis which includes at least 30 percent water soluble extractive and 4-7 percent ash. An unblended Black tea composes about 25 percent water soluble extractive and 4-7 percent ash.

The flavor of Black tea ranges from savory to sweet which depends on the oxidized time and how it was heat processed. Typically Black tea is more astringent and bitter in comparison to green tea but is correctly brewed; it could be smooth and flavorful.

History of Black Tea

Black tea is the first tea type which was introduced to the Middle East and Europe. After it got commercial success in the West, this led to the large scale production in China. The production of black tea spread when the Scottish and English entrepreneurs and adventurers stole tea seeds and plants from China.
