According to official data, the shelf life of Lipton black tea is generally 18 months. The shelf life of sealed packaged tea ranges from 12 months to 24 months.

Things like tea bags are still very expensive. When purchasing easily perishable tea, pay attention to the production date and expiration date. Try to drink it as soon as possible after opening. It is not storage-resistant.

Roasted black tea such as Wuyishan Lapsang Souchong Black Tea is better preserved.
