Comprehensive Guide to Green Tea | History, Types, and Health Benefits
Green tea is a type of tea that is made from the leaves of the Camellia sinensis plant.
Unlike black tea, which is fully fermented, green tea is not fermented at all, which helps to preserve its natural color and flavor.
How Green Tea is Made
Green tea undergoes minimal oxidation during processing, which helps retain its natural green color and delicate flavor.
General Process
Withering
Freshly picked tea leaves are spread out to wither and remove excess moisture
Steaming or Pan-firing
The leaves are quickly heated to halt oxidation. In Japan, steaming is the common method, while in China, pan-firing is employed.
Rolling
The leaves are rolled or shaped to release enzymes and enhance flavor development
Drying
Finally, the leaves are dried to remove any remaining moisture, preserving the quality and flavor.
History of Green Tea
The history of green tea can be traced back to ancient China, where tea cultivation and consumption began. According to legend, the discovery of tea dates back to around 2737 BCE during the reign of Emperor Shennong. It is said that while boiling water under a tea tree, some leaves accidentally fell into the pot, resulting in the first cup of tea.
Green tea was initially consumed for its medicinal properties. In ancient China, tea was highly valued for its supposed healing properties and was used to treat various ailments. It was believed to have cooling and detoxifying effects on the body.
During the Tang Dynasty (618-907 CE), tea cultivation and processing techniques were further developed. The methods of steaming and drying tea leaves were refined, laying the foundation for the production of green tea as we know it today.
During the Ming Dynasty (1368-1644 CE) and Qing Dynasty (1644-1912 CE) in China, tea production and trade flourished. Green tea gained popularity both domestically and internationally, with increased demand from European traders.
In the 19th and 20th centuries, green tea production methods were further refined, incorporating modern machinery and techniques to improve efficiency and quality. Today, China remains a major producer and exporter of green tea.
