Different teas must be stored in different conditions according to the above requirements, otherwise it is not conducive to quality maintenance. If green tea is not stored refrigerated, it will have a noticeable stale taste within 3-5 days in the hot summer months. If pu-erh tea is stored in an environment with humidity higher than 80%, it will have a distinct musty smell. The storage environment has a great influence on the flavor of tea, for example, the pu-erh tea has Guangdong storage, Hong Kong storage, Malaysia storage, Kunming storage, etc. This is because the tea is stored in different areas for a long time and the difference in local climatic conditions has an impact on the quality changes.
