Dive Deep Into Green Tea | What Is It & What Are The Benefits?

Green tea is said to have great health benefits and can be considered as an alternate to coffee. It’s also used in fat burner pills. Green tea as well as black tea originates from a plant species – Camellia sinensis – though the preparation method for green tea is different than black tea.

Plant Varieties

Green Tea Plant Seeds Camellia Sinensis

Camellia sinensis is the botanical name of the tea plant and has two different varieties which produce all the different types of tea. These can be used to make any type of tea. The only difference in is the processing method.

? Camellia sinensis sinensis – The leaves of this variety is small and is mainly produced in China. It grows on mountainous areas and needs mild sunshine and cold air. This variety is used to manufacture green tea.

? Camellia sinensis assamica: The leaf of this species is bigger and is grown in Assam region of India & is used to produce black tea .The crop is cultivated in moist climate and warm weather.

Green Tea Manufacturing

green tea processing

The leaves from the plant Camellia sinensis are harvested and are quickly heated using the process of pan firing or steaming. They are then dried enough to ensure that there is not much oxidation, else the leaves will turn brown and the flavor would go off. If the tea leaves are oxidized completely the end product is black tea, so the processing of green tea is of utmost importance. A perfectly brewed green tea is light in color and has a yellow-green appearance.

The taste is also dependent on many other factors like at what time the tea leaves were plucked and from which part of the plant the leaves were from. In fact, the heating temperature as well as leaf size also determines the taste, as well as by the other crops grown around tea plantation as well as the kind of trees that are providing shade to them. The weather can also contributes to the taste!
