Can black tea be soaked in cold water?

All kinds of scented tea, black tea and low-grade green tea should be brewed with 90- 100 degree boiling water. When the water temperature is low, the active ingredients in tea are precipitated less, and the tea taste is light.

Have another drink. People in China have the habit of drinking hot tea, which is the experience gained from drinking tea for a long time. Because tea contains a variety of effective components, it has high solubility in hot water. Therefore, drinking hot tea can give full play to the role of tea and maintain its color, aroma and taste.

Physiological experiments have proved that water cannot be absorbed in the stomach, and water entering the stomach needs to flow into the small intestine to be absorbed. It takes 40-50 minutes for 500 grams of cold water to completely flow into the small intestine. If you drink hot water, you can accelerate the contraction of the stomach wall, promote the opening of the pylorus of the stomach, and make water flow into the small intestine quickly and be absorbed. So drinking hot tea can meet the human body's demand for water as soon as possible. This is the truth of "drinking hot tea to quench thirst". Furthermore, hot tea can soften food, strengthen the contraction of stomach wall, promote the secretion of gastric juice and help food digestion. To sum up, drinking hot tea is more beneficial than drinking herbal tea.
