Dear, cold tea-making is mainly a tea-making process developed and popularized in recent years, and it is a tea-making process with purified water filtered at normal temperature and high density. In cold water, the sweet amino acid molecules in tea are easy to dissolve out first, which reduces the release of caffeine, does not hurt the stomach or affect sleep, reduces the release of tea tannin, avoids bitterness, enhances natural sweetness and is easier to eat.

Traditional high-temperature boiling water brewing may lead to the release of theophylline, tannic acid, caffeine and other harmful substances in tea due to high water temperature and long soaking time.

Cold soaking can reduce the caffeine content in tea soup and reduce the burden on the stomach wall: caffeine in tea can be easily dissolved at high temperature, thus increasing the secretion of gastric acid, and some people with bad stomachs will feel a little uncomfortable when drinking a lot; Cold-brewed tea leaves "catechins" and "tea polyphenols" in tea, which can effectively promote gastrointestinal peristalsis and remove stool, and has a very effective role in slimming and preventing cancer.

Herbal tea can be brewed as long as there is pure water, mineral water or boiled and cooled water, without heating, which can save huge energy such as electricity, gas and charcoal fire. Simple and convenient, you can drink it whenever you need it: in places where you can't boil hot water, you can drink tea as long as you have pure mineral water. It's really healthy to drink without essence.

Honey, it is generally not recommended to brew herbal tea now, because it requires a certain release process of tea soup. However, Yadaogong tea has herbal tea to take away, and it is made of high-quality Qimen black tea. I bought it. It tastes really good.
