Yes, you can. The shelf life of Pu 'er tea is 60 years, or 100 years, or hundreds of years. Without conclusive data, the degree of aging is often judged only by the intuition of tea tasters. Pu 'er tea is not as old as possible. Only qualified products will change in the direction of "good" within a certain period of time under suitable storage conditions.

The shelf life of sealed tea leaves is 12 months to 24 months. The shelf life of bulk tea is shorter, because the process of leaving it outside in bulk will absorb moisture and odor, which not only makes the tea lose its original flavor, but also makes it easier to deteriorate.
