How To Make Green Tea?

2021-06-23 15:57:09

The processing of green tea can be simply divided into three steps: fixation, rolling and drying. The key lies in the first process of initial production, that is, fixation. The fresh leaves are inactivated and the enzyme activity is inactivated. The various chemical components contained therein are basically subjected to physical and chemical changes under the condition of no enzyme influence by the action of heat, thus forming the quality characteristics of green tea.

1. Fixation

The quality of green tea plays a decisive role. The high temperature destroys the properties of enzymes in the fresh leaves and prevents the oxidation of polyphenols to prevent the leaves from reddening; at the same time, part of the water in the leaves is evaporated to soften the leaves, creating conditions for rolling and shaping. With the evaporation of water, the low-boiling aromatic substances with grassy aroma in the fresh leaves volatilize and disappear, so that the aroma of the tea is improved. Except for special teas, this process is all carried out in a fixation machine. The factors that affect the quality of the fixation include the fixation temperature, the amount of leaves, the type of the fixation machine, the time, and the fixation method. They are a whole and are interrelated and restrict each other.

2. Kneading(Rolling)

Twisting is a process of shaping the shape of green tea. Through the use of external force, the tea leaves crushed and lightened, rolled into strips, the volume is reduced, and the brewing is convenient. At the same time, part of the tea juice squeezes and adheres to the surface of the leaf, which also plays an important role in increasing the concentration of tea flavor. The kneading process of green tea is divided into cold rolling and hot rolling. The so-called cold kneading refers to the kneading of the green leaves after being spread and cool; the hot kneading refers to the kneading of the green leaves while they are hot without spreading the cold. The young leaves should be cold twisted to keep the bright yellow-green color of the soup at the bottom of the tender green leaves, and the old leaves should be kneaded hot to facilitate the tightness of the rope and reduce the debris. At present, in addition to the manual operation of famous tea, the rolling operation of bulk green tea has been mechanized which called tea rolling machine.
