The preservation period of Pu'er Tea does not have a fixed number, as it depends on various factors such as the type of tea (raw or ripe), processing methods, storage conditions, and personal preferences. Under proper storage conditions and with high-quality raw materials, Pu'er tea can be preserved for 15 to 20 years, or even longer.

Is 20-Year-Old Pu'er Tea Still Drinkable?

The drinkability of 20-year-old Pu'er tea depends on its nature and the conditions under which it has been stored. It is recommended not to consume any tea that has spoiled or developed an off-taste, as this could negatively impact your health.

1. Drinkable: Pu'er tea contains nutrients such as polyphenols, vitamins, and Caffeine, and as a dried product, it has a long shelf life, typically 10 to 20 years. If the Pu'er tea has been stored properly, for example, in a well-ventilated and dry environment without any signs of mold, spoilage, or expiration, it is generally still safe to drink. In fact, the longer Pu'er tea is stored, the more intense its aroma becomes, and the better its taste, which should not adversely affect your health. However, when drinking Pu'er tea, it's important to do so in moderation, especially in the evening, to avoid affecting your sleep quality.

2. Not Drinkable: Storing Pu'er tea for 20 years is a relatively long period. If the tea has expired or if it has been stored in damp and dark conditions, it may become spoiled or moldy, making it unsuitable for consumption. This can affect the taste of the tea and potentially harm your health, causing adverse reactions such as abdominal pain, bloating, and diarrhea.
