The pile-Fermentation process is a critical step in the production of ripe Pu'er Tea, and the pile-fermentation time typically lasts around 45 to 60 days. However, the exact duration may vary due to factors such as the tenderness of the tea leaves, the temperature and Humidity of the fermentation environment, among others.
The pile-fermentation of ripe tea is a relatively complex and crucial process, usually taking about 45 to 60 days, but the actual duration can be significantly influenced by various factors.
The tenderness of the tea leaves is an important factor. Relatively tender leaves react faster during fermentation and may require slightly less time; whereas coarser, older leaves might need more time to complete the fermentation adequately. The temperature and humidity of the fermentation environment play a critical role. Suitable and stable temperatures promote microbial activity, while appropriate humidity ensures good progress of fermentation. If the temperature is too low, the fermentation process may slow down, extending the required time; if the humidity is too low, it may result in insufficient fermentation, and conversely, if it's too high, over-fermentation or other adverse conditions may occur. Ventilation conditions are also significant, as proper ventilation provides an appropriate oxygen environment for fermentation, ensuring normal microbial activity.
Different tea manufacturers, based on their own traditional techniques and accumulated experience, as well as their pursuit of specific quality and style in ripe tea, may exhibit flexibility and differences in controlling the pile-fermentation time. Some may shorten or extend the fermentation time to achieve unique taste and flavor profiles. The expertise and judgment of the tea master are also crucial in this process, as they adjust the fermentation process precisely according to the real-time state of the tea leaves to ensure that the final ripe tea displays the best quality and characteristics. In summary, determining the pile-fermentation time for ripe tea is a process that requires careful consideration and precise control of multiple factors.
