History and Origins of Green Tea Green tea's history dates back to 2737 BCE in China, where legend says Emperor Shen Nong discovered it when tea leaves accidentally fell into his boiling water.
Key Historical Developments: Tang Dynasty (618–907 CE): Tea became a popular drink, and the first tea book, The Classic of Tea, was written.
Song Dynasty (960–1279): Powdered tea (matcha) emerged.
12th Century: Japanese monks brought tea seeds from China, leading to Japan’s tea culture.
17th Century: Dutch traders introduced green tea to Europe.
Today, China and Japan remain the largest producers, each with distinct processing methods.
How Green Tea is Made Green tea is minimally oxidized, preserving its natural polyphenols. The process includes:
Harvesting:
Hand-picked for premium teas (e.g., Longjing)
Machine-harvested for commercial grades
Withering:
Fresh leaves are spread out to reduce moisture.
Heat Treatment (to Stop Oxidation):
Chinese method: Pan-fired (e.g., Dragon Well) for a toasty, nutty flavor.
Japanese method: Steamed (e.g., Sencha) for a grassy, umami taste.
Rolling & Shaping:
Leaves are rolled into needles, curls, or flat shapes.
Drying:
Final drying ensures long shelf life.
