The shelf life of Pu'er Tea cake is 10 to 20 years. Pu'er tea is made from sun-dried rough tea produced in specific regions of Yunnan and is a loose or Compressed tea that undergoes post-fermentation. According to the execution standard GB/T22111-2008, it can be stored for a long time, but it is generally recommended to store it for 10 to 20 years to reach its optimal tasting period. Beyond this period, the flavor will decline.

Pu'er tea cakes can be stored for over 10 years

Pu'er tea is one of China's top ten famous teas. Under proper storage conditions, Pu'er tea cakes can be stored for more than 10 years, possibly even longer. Since Pu'er tea is a post-Fermented tea, the active enzymes inside continue to change during storage.

For high-quality Pu'er tea, the longer it is stored, the more it continues to ferment over time, resulting in better taste. However, the flavor may become somewhat aged and lighter. If improperly stored, its shelf life will be shortened, and it may develop mold and spoil.

When storing Pu'er tea cakes, avoid placing them in damp or high-temperature environments. Maintain a temperature around 20°C to 30°C and prevent them from coming into contact with items with strong odors to avoid flavor contamination. Alternatively, seal them and store them refrigerated.

Improper storage conditions or unscientific indefinite storage will inevitably reduce its quality. Even for Pu'er tea that has reached optimal quality, further indefinite storage will cause the beneficial aging components to gradually decompose and oxidize, losing the special flavor characteristic of Pu'er tea.
