Introduction
Under normal circumstances, the reasons why Pu'er tea is not suitable for drinking by boiling include destruction of nutritional components, deterioration of taste, increased extraction of soluble substances, difficulty in controlling aroma, and possible irritation to the gastrointestinal tract. To preserve the nutritional components, taste, and aroma of Pu'er tea, and to avoid excessive extraction of undesirable substances and gastrointestinal irritation, it is recommended to drink Pu'er tea by steeping it in hot water.
Generally speaking, there are several reasons why Pu'er tea is not suitable for boiling: destruction of nutrients, deterioration of taste, increased extraction of substances, difficulty in controlling aroma, and possible gastrointestinal irritation. Details are as follows:
1. Destruction of Nutrients
Pu'er tea contains various nutrients, including polyphenols, minerals, carbohydrates, and more. When boiled, high temperatures may destroy these nutrients, reducing the tea's nutritional value and health benefits. In particular, antioxidants such as tea polyphenols may lose their activity at high temperatures, thus reducing their health-promoting properties.
2. Deterioration of Taste
When Pu'er tea is boiled, the extended brewing time causes excessive release of tea components, resulting in a highly concentrated infusion with a bitter, astringent, or overly strong taste. In contrast, steeping Pu'er tea in hot water better preserves its aroma and flavor, producing a smoother and more mellow tea infusion.
3. Increased Extraction of Substances
Boiling Pu'er tea increases the extraction of substances from the tea leaves, including potentially undesirable compounds such as excessive caffeine. Too much caffeine may stimulate the cerebral cortex, cause nervous excitement, and affect sleep quality.
4. Difficulty in Controlling Aroma
When Pu'er tea is boiled, it is difficult to properly control the aroma and flavor. In contrast, steeping allows better regulation of the tea's strength and aroma by adjusting the amount of tea leaves and steeping time.
5. Possible Gastrointestinal Irritation
Boiling Pu'er tea often results in an overly concentrated infusion, which may irritate the stomach and intestines, causing discomfort. Individuals with weak digestive systems may experience increased gastrointestinal stress after consuming boiled Pu'er tea.
To preserve the nutrients, taste, and aroma of Pu'er tea, and to avoid excessive extraction of undesirable substances and gastrointestinal irritation, it is recommended to consume Pu'er tea by steeping it in hot water. By controlling the amount of tea and steeping time, one can prepare a more delicious and healthier cup of tea.
