[0002] Tea pile fermentation is a fermentation process in the production of Pu'er tea, and it is also the key point to determine the quality of cooked tea. It means piling up the sun-dried green tea to a certain height, sprinkling water on it, and covering it with linen to promote the action of tea enzymes. It is fermented under the action of moist heat for about 24 hours. After the tea leaves are converted to a certain degree, they are spread out to dry. After the tea leaves have been piled up, their color has changed from green to yellow, chestnut red, and chestnut black, depending on the degree of piling. Academically, they are classified as black tea.
