Can you still drink tea leaves that have been left for five or six years?

No, the shelf life of tea is up to two to three years, if it is too long, it will affect the taste and will also lead to the loss of nutrients in the tea.

According to the tea sold on the market, the tea is generally maintained in a sealed environment for 1 2 years, except for special varieties, each tea will indicate the shelf life and production date on the outer packaging, and the merchant will not sell expired tea. Whether tea can be drunk for five or six years depends on the variety and production process of tea, and the shelf life of each tea is different, and there is no defined standard. Tea leaves like Pu'er tea have no problem at all if they are stored for five or six years, while green tea cannot be drunk after being stored for so long.

The shelf life of green tea is generally about 12 to 18 months (the same is true for yellow tea), which is not suitable for a long time. The longer you leave it, the less freshness you have, and the less concentrated the flavor it used to be.

Oolong tea is a semi-fermented tea, generally speaking, lightly fermented, or oolong tea with a low degree of roasting, is generally stored for about 2 years. For the rock tea and aged Tieguanyin that are properly fired, they can generally be stored for 5 to 10 years.

Black tea is a completely fermented tea, the internal substance of the tea is relatively stable, the impact of oxidation is naturally smaller, and the quality is stable, and it can be stored properly. It generally has a shelf life of 2 to 3 years, and is not suitable for long-term storage.

White tea and black tea are very valuable for storage, after a long period of transformation, the taste and quality will be improved, especially white tea, we have always had the saying of "one year of tea, three years of medicine, seven years of treasure". However, this is on the premise of proper storage.
