After choosing the tea that suits you, how to make it work is also a science. Experts said: "Different teas, methods of preservation, brewing and drinking have their own specialties."
Nutritional components of tea:
Through the separation and identification of modern science, tea contains more than 450 kinds of organic chemical components and more than 40 inorganic mineral elements. The organic and inorganic mineral elements in tea contain many nutrients and medicinal ingredients. The main organic chemical components are: tea polyphenols, plant alkaloids, proteins, amino acids, vitamins, pectin, organic acids, lipopolysaccharides, carbohydrates, enzymes, pigments, etc. The Tieguanyin contains organic chemical components, such as tea polyphenols, catechins, a variety of amino acids and other content, significantly higher than other tea. Inorganic minerals are mainly: potassium, calcium, magnesium, cobalt, iron, manganese, aluminum, sodium, zinc, copper, nitrogen, phosphorus, fluorine, iodine, selenium and so on. Tieguanyin contains inorganic mineral elements such as manganese, iron, fluorine, potassium, and sodium that are higher than other teas.
Tea preservation method: Tea is most afraid of damp odor
The containers preserved by tea are tin bottles, porcelain jars, and colored glass bottles; secondly, iron-listening, wooden boxes, and bamboo boxes are the best; plastic bags and cartons are the most frequent. Containers should be dry, clean, and have no odor. The well-preserved tea should be placed in a dry and ventilated place, and it should not be placed in a place exposed to moisture, high temperature, uncleanness or exposure. These places can not have camphor, drugs, cosmetics, cigarettes, detergents and other items with a strong smell. The new green tea of ​​that year can also be sealed and placed in the refrigerator freezer, which can save 3-6 months.
Tea brewing method: washing tea for up to 15 seconds
Now people like to drink tea, but do not agree with excessive tea. It was found in the experiment that the leaching rate of active ingredients in green tea was twice more than 70%, and that of black tea was more than 60%. In other words, if you over-wash your tea, nutrients will be lost. If tea has to be washed, do not wash the tea for more than 15 seconds. Green tea and white tea, it is best not to wash. “But there is an exception. Those who are more sensitive to caffeine can wash it before drinking tea, because caffeine is leached faster than tea polyphenols, and quick crock can remove some caffeine.â€
Tea drinking method: 12g per day is most suitable
For the average person, drinking about 12 grams a day, brewing 3 to 4 times is appropriate. People who eat more greasy food and have a large amount of tobacco and alcohol can increase the amount of tea. Pregnant women and children, neurasthenia, tachycardia, the amount of tea should be reduced.
The optimal water temperature for making tea: between 70°C and 80°C
With the popularity of Kung Fu tea, people are becoming more and more hot when they drink tea. This is very wrong. "People drink tea as health care, but drinking hot tea increases the incidence of cancers such as esophageal cancer, and it is not worth the candle.
What is the best water temperature for making tea? Amino acids in tea are good for the human body and they dissolve out when the water temperature is 60°C. Vitamin C is damaged when the water temperature is 70°C. Tea tannin and caffeine gradually dissolve out when the water temperature is 70°C. If the water temperature is too high, the taste of the tea is too bitter.
Therefore, in order to maintain the nutrition, taste and aroma of the tea, the water temperature of the tea is preferably between 70° C. and 80° C. It is generally preferable to pour boiling water into the thermos bottle first, and then it is better to make tea.

Especially the elderly, black tea, Pu'er tea can be appropriate to drink a little more, green tea, oolong tea to drink less, especially oolong tea, because it's tea is already relatively strong, pay attention to drink less.
According to the book or the tea artisan recommended the best ratio of brewing, the elderly can be lighter, especially the new tea is more cold, because the tea storage time is too short, more polyphenols, alcohols, aldehydes content. Therefore, although the new tea is fragrant, it should only be lighter and not suitable for drinking.
