Pu'er tea does not necessarily improve with age; this depends on the storage method and the quality of the raw materials. The aging process of Pu'er tea is influenced by factors such as time, light, temperature, and Humidity. Pu'er tea should not be completely sealed but should be exposed to air to undergo oxidation. High-quality large-leaf raw materials will fully transform and become richer during the aging process. According to Little Tea Master, these two conditions must be met for Pu'er tea to improve with age.
Is Older Pu'er Tea Always Better?
In the Chinese Pu'er tea collection community, the longer Pu'er tea is stored, the better it becomes—a rule that many collectors follow, often using age as the sole criterion. This is one reason why Pu'er tea is collected and stockpiled in large quantities. But is older really better?
If Pu'er tea is properly stored, it will indeed become more fragrant over time. However, you might notice a Shelf life indicated on the packaging. This is because food products are required by law to have an expiration date, but consumers do not need to pay much attention to it when drinking Pu'er tea. If you detect a moldy smell in the tea, it is likely due to improper storage, and such tea should not be purchased.
New Pu'er tea has a strong, intense flavor that can be less appealing to those accustomed to high-altitude teas or aged Pu'er teas. Older Pu'er teas, having undergone significant post-oxidation, become milder and less stimulating. They are said to promote blood circulation, be non-irritating to the Stomach, and even have Health benefits. As the tea ages, the degree of oxidation increases, resulting in a smoother taste.
Three Key Factors for Storing Pu'er Tea
1. Stable Temperature: The temperature where Pu'er tea is stored should not be too high or too low. It is best to maintain the natural room temperature, ideally between 20°C to 30°C (68°F to 86°F). High temperatures can cause the tea to ferment too quickly and turn sour. Regardless of the season, avoid exposing the tea directly to sunlight and keep it in a cool place.
2. Circulating Air: Oxygen in circulating air helps microorganisms thrive, accelerating the changes in the tea. However, do not hang the tea out in the open or in direct sunlight, as this can cause the tea to lose its flavor and aroma. A moderate level of air circulation is ideal, but avoid placing the tea near vents or in areas with strong odors from daily life or industry, as these can affect the tea's taste.
