During the Song dynasty (960-1279 AD), powdered tea became popular in China, a practice that laid the groundwork for the Japanese tea ceremony.

Over time, it became an integral part of Japanese culture, especially in the form of matcha.In Japan, tea evolved from a luxury item for the elite to a widespread beverage enjoyed by all social classes, especially with the advent of Sencha (steamed green tea) in the 18th century.

Similarly, in Korea, tea was introduced by Chinese monks and became a part of Korean rituals. Other neighboring countries like Vietnam also adopted tea into their culture, each developing unique brewing methods and ceremonies.

European Spread !

Portuguese priests and merchants touring China during the 16th century, eventually brought tea to Europe, which become a valuable commodity. While initially popular, green tea eventually gave way to black tea in Europe, particularly in Britain, due to factors like longer shelf life and brewing habits.

Green Tea Manufacturing

The making of green tea is an art that has been refined over centuries, with each step in the process crucial to the development of the tea’s flavor, aroma, and color. 

The journey of manufacture of Green tea starts from the plantaion of Camellia sinensis plant. This variety of tea plant thrives in subtropical climates which include high altitudes, frequent mist, and a good balance of sunshine and rainfall.

Different varieties of the Camellia sinensis plant are cultivated based on the desired characteristics of the final tea product. Some teas, like matcha, require specific cultivars.

Similaraly , harveting time affect the quality and taste of tea.The first flush (first harvest of the year) usually yields the highest quality leaves. Traditional methods often involve hand-picking the top two leaves and the bud.

For certain teas like matcha and gyokuro, process is to shade tea plants for several weeks before harvesting. This increases chlorophyll levels and amino acids, contributing to a richer flavor.

7 Steps of Tea Processing

Green tea production is a blend of tradition and technology, with each step meticulously carried out to ensure the highest quality.The processing steps include steaming the tea plants ,rolling ,drying ,sorting and grading the tea.

  1. Immediately after harvesting, the leaves are either steamed (Japanese method) or pan-fired (Chinese method). Steaming halts oxidation and preserves the green color, while pan-firing gives a more roasted flavor.
  2. The leaves are then rolled into various shapes. This step also breaks down the cells within the leaves, enhancing the flavor and aroma.
  3. Finally, the leaves are dried to remove moisture, which stops enzymatic activity and stabilizes the green tea for storage.
  4. The tea is sorted and graded based on leaf size, shape, and color. Higher grades of tea have uniform leaves and a more vibrant color.
  5. Some teas undergo additional steps, like grinding in the case of matcha, to achieve the desired final product.The Matcha variety of green tea requires a unique process where the dried leaves are de-veined and de-stemmed before being stone-ground into a fine powder. This retains the nutrients and allows the whole leaf to be consumed.
  6. Proper packaging is crucial to maintain the tea’s freshness, flavor, and aroma. Vacuum-sealing and using opaque containers helps protect the tea from air, light, and moisture.
  7.  Finally , the Green tea is kept in a cool, dry place away strong odors from direct sunlight.
