Is Pu'er tea still drinkable if it has a moldy taste

Pu erh tea has a moldy taste and is usually not recommended for continued consumption. The moldy taste may be caused by improper storage or deterioration of tea leaves. Mild mold growth may only affect the taste, while severe mold growth may produce harmful substances. Pu erh tea is prone to moisture and mold in humid environments, and the moldy taste is a signal of mold growth. The slight moldy smell may be caused by environmental odors adsorbed on the surface of tea leaves, which may be removed by ventilation, air drying, or brief high-temperature treatment. But if the moldy smell is accompanied by obvious discoloration, clumping, or pungent odor, it indicates that the mold has penetrated into the interior of the tea. Harmful molds such as Aspergillus flavus may produce toxins, and long-term consumption poses health risks.

Some aged Pu erh teas naturally produce an aged aroma similar to earthy smell, which can easily be mistaken for a moldy taste. This type of tea usually has a dry texture, a rich and non irritating aroma, and the tea soup is clear and odorless after brewing. But if the storage process is affected by moisture, even slight mold should be discarded to avoid the risk of misjudgment. Old tea drinkers can assist in judging by observing the tightness of the tea cake, the color of the tea soup, and the aftertaste of the throat.

It is recommended to store Pu'er tea in a cool and dry place, avoiding direct sunlight and high temperature and humidity environments. Regularly check the condition of tea leaves and promptly deal with any mold or mildew found. Smell the dry tea before drinking, observe whether the tea soup is cloudy after brewing, and taste whether there is any odor. Choose legitimate channels to purchase Pu erh tea with guaranteed quality, and store the new tea for 3-5 years before drinking it for a better flavor. People with gastrointestinal sensitivity or weakened immunity should avoid drinking any tea leaves that may have concerns about mold growth.
