Withering is the first process in making black tea. Under normal climatic conditions, when fresh leaves are thinly spread for a period of time, water evaporates mainly. With the extension of the withering time, the self-extraction and decomposition of the contents of the fresh leaves gradually strengthened. With the continuous loss of fresh leaf water, the leaves gradually shrink, the leaf quality changes from hard to soft, and the leaf color changes from bright green to dark green. At the same time, the endoplasm changes and the fragrance also changes. This process is called withering.
The withering process is the physical change of withering on the one hand, and the chemical change of withering on the other hand. These two changes are interrelated and restrict each other. Physical changes can not only promote chemical changes, but also inhibit chemical changes, and even affect the products of chemical changes. Anyway, chemical changes also affect the progress of physical changes. The development and mutual influence between the two vary greatly depending on the external conditions such as temperature and humidity.
The external conditions that affect withering are firstly water evaporation, secondly temperature, and again the length of time. Among them, temperature has the most significant effect on the quality of withered leaves. When using the tea withering machine to wither, it is advisable to adopt the operating principles of “large first and then small” and temperature “first high and then low”. Master a certain amount of time to achieve the required degree of withering.
