Disadvantages: cold water tea is kept for a short time, and cold tea should not be kept for too long. Try not to drink cold tea for more than 8 hours, so as not to hurt your stomach.

Green tea can also be cooled first and then heated. After putting the tea leaves in, soak them in a little drinkable cold water at room temperature for about three minutes, so that the tea leaves can absorb enough water and fully stretch, and then inject enough hot water at one time. At this time, the temperature of hot water can be slightly higher, 85-95℃.
