Cold water can make tea. Cold tea making is to soak tea leaves in cold water at low temperature for about 10 hour, so that the fragrance and nutrients of tea leaves can be released slowly. The experiment found that compared with ordinary hot water tea, cold water tea has much more benefits. The amount of catechins and polyphenols dissolved in the original hot tea can be effectively extracted, and the contents of caffeine and tannic acid are much lower.
