Tea is a beverage rich in nutrients. Tea contains tea polyphenols, tannins, aromatic substances, amino acids and multiple vitamins. If you use a thermos cup to brew tea, the temperature is always kept very high, which will affect the taste and function of the tea. If you are more pursuing the taste and benefits of drinking tea, it is best to use a purple clay teapot or ceramic tea set to brew. On the one hand, it can keep the heat for a long time, and on the other hand, it can make up for the lack of nutrient loss. At the same time, pay attention to the water temperature.
