The reason for this regret is that the stored tea often does not have the expected flavor. Instead, the tea may have an ashy taste, mixed with strange odors, or even worse, dampness and moldy flavors that make it unpalatable. Have you encountered similar issues? Let's discuss how these problems arise and what you can do if you encounter them.

Everything happens for a reason, and the decline in the taste and quality of your stored tea can typically be attributed to one of the following factors:

1. Poor Quality of the Tea Itself

As the saying goes, “the proof of the pudding is in the eating.” When it comes to the taste of tea, the most crucial factor is the quality of the raw materials used. If the raw materials are subpar, even the best processing techniques and storage conditions cannot produce a high-quality tea with a rich, sweet taste, rapid and intense aftertaste, and a fragrant aroma.

2. Inadequate Storage Conditions

While the initial processing plays a crucial role in determining the quality of Pu'er tea, proper storage is equally important. Many enthusiasts, especially those who are particularly discerning, spend a lot of effort selecting and purchasing their tea. However, once they have the tea in their possession, they often neglect proper storage. Some store their teas without considering the issue of cross-contamination between different types of tea. Others fail to follow the recommended storage instructions, leading to dampness and mold.

These two factors are the main causes of changes in the taste of Pu'er tea. However, if you encounter such issues, there's no need to panic. Depending on the severity of the change in quality or taste, you can take appropriate measures.

For teas where the change in taste is not too significant, you can process the tea further by sun-drying it or increasing the number of rinses. Sun-drying helps evaporate any excess moisture within the tea cake and can also eliminate harmful bacteria, improving the tea's aroma and taste.

However, our tolerance for “off-flavored” tea should have limits, especially when it comes to protecting our health. If you encounter odors that trigger natural aversions, such as moldy or sour smells, which are irreversible, it's a sign that the tea's quality is compromised. In such cases, it's best to dispose of the affected tea.

Although Pu'er tea is known for getting better with age, it's still recommended to consume it soon after purchase for optimal taste. If you choose to store tea, try to minimize the storage period to ensure the best possible tasting experience. For storing tea, follow the specific guidelines and precautions for storing Pu'er tea. Even if you're not an expert, your tea will still maintain a decent flavor.
