Brief Information of green tea
Green tea is a tea made from leaves of Camellia Sinensis leaves. There are two varieties of Camellia Sinensis shrubs: Camellia Sinensis Sinensis and Camellia Sinensis Assamica. (22) (23)
- Camellia Sinensis Sinensis: This is native of China which is typically used to make Green Teas and White Teas. It grows as a shrub in Sunny regions with a dry and cold climate. It grows well in mountain ranges also. The leaves of this shrub are small in size.
- Camellia Sinensis Assamica: This is native of India, especially in Assam, and typically used to make strong black teas. It grows in Warm, Moist, and subtropical forest areas. The leaves of this shrub are large.
Many other Camellia Sinensis hybrids are cultivated over time but the oldest are the above ones.
Let us understand a little bit more about the classification of teas and where does Green Tea stands in this diverse world of teas.
There are two types True Teas and Herbal Teas.
- True Teas are made from Camellia Sinensis leaves – Green Tea, Black Tea, White Tea, and Oolong Tea.
- Herbal Teas are made up of dried fruits, flowers, spices, or herbs – Chamomile Tea, Peppermint Tea, Hibiscus Tea, Ginger Tea, Lemon Balm Tea, Cinnamon Tea, etc.
Coming to True Teas the main distinguishing factor is the Degree of Fermentation that leaves are made to undergo. The fermentation here means enzymatic oxidation that tea is allowed to undergo by allowing the fresh leaves to dry. This oxidation may be stopped by pan-frying or steaming the leaves before they completely dry out. Depending on the amount of degree of fermentation tea may be classified as :
- Non-Fermented or Lightly Fermented Tea (0% to 10% Fermentation) – These teas undergo minimum oxidation, therefore retaining a lot of their original flavor. They also retain maximum oxidants due to a lesser amount of oxidation. Green Tea falls into this category.
- Semi Fermented Tea (10% – 80% Fermentation) – Tea processed from semi-fermented tea leaves have light yellow or brownish color and have a subtle aroma. Oolong Tea, Champagne Oolong Tea, and Jasmine Tea are a few examples in this category.
- Fully Fermented Tea ( More than 80% fermentation) – Teas with more than 80% of fermentation are considered fully fermented. They are dark reddish in color and sweet smell. Black Tea comes under this category.
The figure shows the difference between green and black tea processing and its influence on the final polyphenol content.
**EGCG – Epigallocatechin -3 gallate, EGC – Egallocatechin, ECG – Epicatechin – 3 – gallate, EC – Epicatechin
- Withering – It is carried out by spreading leaves thinly on racks or shelves.Air is blown to make them soft and flexible.Dried till moisture content is lowered to 40%.It takes 16-24 hours for the leaves to wither to the required degree.
- Rolling – The withered leaves are then rolled to break open the cells and release the juices and the enzymes. The flavour characteristic inherent in various teas partially depend on the rolling technique used.Curled,Crushed and Torn techniques are used for rolling.
- Fermentation (Here) – After rolling, leaves are spread thinly on suitable platforms and allowed to ferment 2-6 hours at temperature between 21-27 degree centigrade. Phenolic compounds are oxidised to form new phenolic compounds. Colour, Taste and Aroma changes with fermentation.
- Firing – The fermented leaf is passed thrpugh drier.The leaf is dried at 87-93 degree centigrade for 30-40 min.Some caramelisation occurs at this phase too.

Another main cause of heart failure is Clot formation known as Thrombosis. This blood clot obstructs the flow of blood to any part of the heart resulting in a heart attack.
The aromatic green tea protects our heart from High Cholesterol levels and Blood clots. It prevents the oxidation of LDL minimizing the chances of heart disease. It prevents the formation of blood clots and helps the blood vessels to withstand the changes in blood pressure.
