Generally speaking, Pu'er tea does not have a specific expiration date. As long as it is stored properly, it can be kept for an extended period. The longer the Pu'er tea is stored, the higher its collection value becomes. However, in terms of taste, it is best to age Pu'er tea for more than five years. Once it has been stored for around ten years, it becomes aged Pu'er tea. Aged Pu'er tea possesses unique aromas that fresh tea leaves do not have, which are developed through long-term fermentation. Moreover, the longer the storage time, the richer the aroma and the milder the nature of the tea becomes.
The Optimal Aging Periods for Pu'er Tea
First Tasting Period
The first three months after the new tea is prepared
For example, spring tea pressed and stored for two or three months. At this stage, the new tea has just lost its moisture. It is strong and full-bodied with a fresh, slightly astringent taste, and its strengths and weaknesses are clear. Its aroma is high and pervasive. This tea is suitable for light tasting.
Second Tasting Period
Between one to two years after preparation
During this time, the fresh and astringent flavors have gradually faded, making the tea slightly milder. After a year's maturation, the tea's internal qualities become more settled, and the taste stabilizes, transitioning from astringency to richness. Defects also fade over time. Tasting at this point reveals the true character and essence of the tea.
Third Tasting Period
Around seven to eight years after preparation
After seven to eight years of aging, the aged flavor starts to emerge. The aroma transforms into countless possibilities over time, such as turning from floral to fruity or honey-like, or developing a rich floral aroma if it was previously weak. The joy of storing tea lies in the unexpected surprises it brings.
Fourth Tasting Period
Dry-stored tea aged for 20 years
This stage of tea is truly “rare and hard to come by.” If you encounter good raw materials, good production techniques, and proper storage conditions, 20-year-old dry-stored tea can be considered “top-quality aged tea.” It boasts a rich aroma, possibly including precious medicinal, camphor, or Ginseng-like scents, with a smooth, rich taste that can be felt on the tongue.
The Best Way to Store Pu'er Tea
1. Direct Storage
Pu'er tea can be stored directly using multiple layers of paper Bags or bamboo shells; there is no need to wrap it in plastic to avoid obstructing air circulation. Similarly, refrigerated storage is not necessary for Pu'er tea.
2. Canister Storage Method
Using a canister to store Pu'er tea is a relatively scientific method, particularly suitable for collectors. A well-sealed canister can effectively prevent the tea from becoming damp, avoid oxidation due to contact with air, and even has a tea-waking effect. It is recommended to use a purple clay or Ceramic canister.
When storing tea in a canister, it should not come into contact with different types of tea to prevent flavor mixing, given that Pu'er tea varieties and aromas vary. Additionally, once placed in the canister, the lid must be sealed to prevent the tea's aroma from dissipating.
3. Economical and Effortless Cardboard box Storage Method
If you're not a collector but simply enjoy drinking Pu'er tea, you can use a simple Cardboard box for storage, which is both convenient and effortless. However, ensure the box is not placed near walls or on the ground, as excess moisture could cause the tea to become damp. Consider placing it on bookshelves or wooden stands.
4. Freshness Preservation Storage Method
If using a canister seems too complicated, you can also use airtight bags to store Pu'er tea. For bags with good airtight seals, their effects are similar to those of canister storage. If you intend to store the tea long-term, using airtight bags makes it easy to check the tea's condition later and facilitates brewing.
