The difference between hot water and cold water brewing tea what are the effects of cold brewing black tea and oolong tea on the body

When summer lotus and cicadas sing open the prelude to summer, at this time, you might as well brew a pot of cold fragrant tea to cool the cold tea to quench your thirst and release the annoyance in your heart. [soak the tea in cold water for a long time and slowly release sweetness] Cold tea, as the name implies, is to brew the tea directly in cold water, so that the tea slowly releases sweetness in cold water, rather than chilling it after brewing it in hot water. When the tea is soaked in hot water and then cooled, the bitter theophylline and tannic acid in the tea are released when heated, even if they are still stored in the tea soup after cooling, soaking the tea directly in the cold water, the tea is not easy to release theophylline and tannic acid, and the taste of the tea is softer and sweeter than the way of cooling after hot soaking. Where does the sweet charm of cold brewed tea come from? Cold brewed tea is brewed in cold water to reduce bitter factors such as caffeine, theophylline and tannic acid. "soaking and releasing sweet amino acids for a long time" is cold extracted at low temperature for a long time, while sweet ingredients such as amino acids in tea are doubly dissolved because they are soaked at low temperature for a long time, which is the reason why cold tea tastes good.

[how to make cold tea] it is easier to soak cold tea than to master the temperature. Just take an appropriate amount of cold boiled water and put the tea in a container. Tea and water are 1g:100c.c. In proportion, cover the bottle and put it in the refrigerator. According to the type of tea, it is chilled for 4 to 8 hours (4 hours for green tea, 4 hours for black tea and 8 hours for oolong tea). The failure rate is low, and ordinary people can easily use it. The way of "cold soaking tea" is different from hot tea first smelling fragrance, and then drinking tea soup taste. When tasting cold tea, the tea soup first sends out taste in the mouth, but can first feel its sweetness. With the rise of oral temperature, the tea soup slowly releases the fragrance of tea, and after drinking it, the throat rhyme will not stop, small mouthfuls or big mouthfuls are suitable. Cold brewed tea has a supple taste and low caffeine content, and people with sensitive constitution can also enjoy drinking tea.
