What is Green Tea ?

Green tea is made from Camellia sinensis leaves. It was originated in China, but the production of green tea leaves has spread to many countries in Asia. Depending upon the Camellia sinensis used, growing conditions, time of harvest, production processing, and horticultural methods, several varieties of green tea exist.

Steeping is the process followed in making a cup of tea. But this steeping time and temperature vary with a different tea. The hottest steeping temperatures are 81 to 87 °C (178 to 189 °F) water and the longest steeping times are two to three minutes. Whereas the coolest brewing temperatures are 61 to 69 °C (142 to 156 °F) and the shortest times are about 30 seconds.

In fact, it is the same as that of black tea but processed differently. The normal black tea is obtained by fermenting the tea leaves. This process changes its color and flavor thereby raising the level of caffeine and tannin. Whereas in the case of Green Tea, the leaves are dried or slightly steamed but not fermented. That’s why it looks green when it was brewed. Green Tea health benefits are mainly due to its antioxidant properties that come from its caffeine, Catechin polyphenols, and theonine content.

Types of Green Tea

Depending upon the leaf length, method of processing, and season of harvesting, greentea has four main types prepared in Japan.

1. Gyokurocha

Under this type, the leaves are plucked from the tip of the branches. When brewed, the color of the tea is clear green. Since it was picked from the tip, it has the best taste and fragrance, and also considered as the best regarding health. Furthermore, it is less bitter because it contains less tannin and caffeine. But the only drawback is its high cost.

2. Sencha

The leaves are plucked from the middle of the branch and are bigger, older and less tender than Gyokurocha. Sencha type gives a clear, light green tea when brewed as well. Naturally, it is more bitter and stronger than the Gyokurocha variety. It is cheaper and more popular than the previous type. Sencha Green tea health benefits are also high.

3. Bancha

This type is made from tender twigs of the tea plant which makes it very strong and bitter. When brewed, it gives a golden brown color. This is an even cheaper version of green tea than the previous two.

4. Matcha

This is the leftover powder of green tea, also called as dust. Matcha makes a beautifully green-colored tea and forms a lot of foam but has a weaker aroma than the other varieties. It is far less bitter than the other three varieties, so when you sip a cup, it seems to hold a natural sweetness, particularly if you have tasted the other varieties. But Matcha green tea benefits are very high.
