High-grade green tea, especially all kinds of famous teas with delicate buds and leaves (green tea famous tea), cannot be brewed with 100 boiling water, and it is generally advisable to use about 80.
The more tender and green the tea leaves, the lower the brewing water temperature, so that the tea soup brewed must be tender and bright, the taste is fresh, and the tea vitamin C is less damaged. At high temperatures, the tea soup is easy to turn yellow, the taste is bitter (the caffeine in the tea is easy to leach), and the vitamin C is destroyed in large quantities.
As usual, the water temperature is high, and the tea leaves are "hot".
To brew a variety of flower teas, black teas, and medium and low-grade green teas, you need to brew with 100 boiling water. If the water temperature is low, the permeability is poor, the active ingredients in the tea are leached less, and the tea taste is weak. To brew oolong tea, pu'er tea and flower tea, the amount of tea used each time is large, and the tea leaves are very old, so they must be brewed with 100 boiling water.
Sometimes, in order to maintain and increase the temperature of the water, it is also necessary to blanch the tea set with boiling water before brewing, and pour boiling water on the outside of the pot after brewing. Ethnic minorities drink brick tea, which requires a higher water temperature, and the brick tea is broken and boiled in a pot.
Generally speaking, the water temperature of tea brewing is positively correlated with the solubility of the active substances in the tea in the water, the higher the water temperature, the greater the solubility, and the stronger the tea soup; On the contrary, the lower the water temperature, the smaller the solubility, the lighter the tea soup, generally 60 warm water leaching amount is only equivalent to 100 boiling water leaching amount of 45-65.
It must be noted here that as mentioned above, high-grade green tea is suitable for brewing with 80 degrees of water, which usually means that the water is boiled (the water temperature reaches 100 degrees) and then cooled to the required temperature; If it is raw water, it only needs to be boiled to the desired temperature.

This depends on what kind of tea it is.

Different teas require different water temperatures to dismantle filial piety.
Tea is divided into black tea, black tea, white tea, green tea, yellow tea, oolong tea, the brewing water temperature of black tea is 90, the brewing water temperature of black tea is 100, the brewing water temperature of white tea is 100, the brewing water temperature of green tea is 85, the brewing water temperature of yellow tea is 85, and the brewing water temperature of oolong tea is 100.
To make a good tea, the right water temperature and time are very important. To put it simply, the basic but not absolute principle of suitable water temperature is that the water temperature of brewed green tea is the lowest, followed by black tea, and oolong is the highest, or the water temperature of young bud tea is lower, and the water temperature of large leaf and old leaf tea is higher.
The brewing time should be determined according to the amount of tea, water temperature, water volume, utensils and methods, the general principle is that the first or second brewing time is the shortest, and the brewing time is gradually lengthened. Depending on the situation and to suit your taste preferences, the right temperature and time are met.
Precautions for making tea:
1. Pay attention to making tea with a thermos cup. Although the thermos cup can keep warm, the multivitamins and aromatic oils in the tea are easy to be lost in high temperature or long-term constant temperature water, and the utility and taste of tea are also reduced. The tea set should be the first to recommend pottery, which has a certain degree of air permeability, keeps warm in winter, is not rancid in summer, and does not have any chemical reaction.
So the purple sand teapot is famous. A regular bubble tea glass is most suitable.
2. Brew with boiling water, pay attention to control the temperature. Some people like to use freshly boiled water to make tea leaves, which is actually very harmful. The high temperature of freshly boiled water can destroy a large number of nutrients in the tea that are not resistant to high temperatures, and the aroma of the tea will disappear quickly.
The water temperature of making tea should be divided according to the old and tender tea leaves, and the old tea can be directly washed into the boiling water of 95; Tender tea should be lower, around 80 is more suitable.
3. The first tea should be filtered. Some people think that the first tea is strong and refreshing, so they love to drink the first tea. As everyone knows, tea is polluted by pesticides and other substances in the process of cultivation and processing, and there are always some pesticides left on the surface of tea, and the corresponding concentration of harmful substances such as pesticides in tea is also high.
Therefore, the first tea should be allowed to play the role of "washing tea" and discarded it.

Different varieties of tea, the temperature of the water is different, taking black tea as an example, the appropriate water temperature is around 90 -95. Tea brewing is an invention of the Chinese, and it is the turning point of the development of Chinese tea culture, which has led to the development of tea utensils, tea ceremony, tea art and tea culture.
Tea making pays attention to tea utensils, water use, water temperature, environment, mood, clothing, etc. Tea brewing technology makes tea drink truly popular.
To make a cup of tea or a pot of tea, you must first master the amount of tea you use. There is no unified standard for how much tea is used each time, mainly according to the type of tea, the size of the tea set and the drinking habits of consumers.
There are many types of tea, different types of tea, and different dosages. The ratio of tea to water is roughly 1:50-60, that is, about 3 grams of dry tea per cup, and 150-200 ml of boiling water is added.

Brewing different kinds of tea requires different water quality and temperature, which are generally divided into the following categories:
1.Green tea: Green tea needs to be brewed with 70 -80 water, and the water quality is better than drinking water or mountain spring water, and boiling water or mineral water should not be used. Because hot water destroys the nutrients and aromas in green tea, wild oranges, and makes the taste bitter.
2.Yellow tea: Yellow tea needs to be brewed with 80 -85 water, and the water quality is preferably drinking water or mineral water. This preserves the original flavor of the yellow tea and the yellow color of the soup.
3.White Tea: White tea needs to be brewed with 85 -90 water, preferably drinking water or spring water. The aroma of white tea itself is very light, and if you brew tea with boiling water, it is difficult to taste its unique flavor.
4.Green tea: Green tea needs to be brewed with 90 -95 water, and the water quality is preferably drinking water or spring water. This activates the various active ingredients in the green tea and gives the tea a richer and more tangy taste.
5.Black tea: Black tea needs to be brewed with 95 -100 boiling water, and the water quality is preferably drinking water or mineral water. Boiling water can effectively activate the organic compounds in black tea, giving the tea soup a thick reddish-brown color.
6.Other teas: Other teas include black tea, pu-erh tea, etc., and the brewing temperature of each tea is different, depending on the specific situation.
In short, the water quality and temperature required for different types of tea are different, which will affect the nutrients, flavor and taste of tea. Before making tea, you must carefully understand the brewing method of each tea and operate it carefully in order to taste the perfect taste of tea.

The influence of water temperature on tea soup cannot be ignored. Many tea people obviously bought high-quality tea (good quality tea is also very important, it is recommended that you can go to the hospitality nine products to book tea, under the tea tree to raise pheasants, less pests, strict quality control. However, the annual tea production of Hospitality Jiupin is small, and it needs to be booked in advance! , but because he didn't grasp the temperature of the tea, the good tea was ruined. So, how much water is good for making tea?
Because green tea belongs to the non-fermented tea category, it is most particular about the shape and color of the outer acres of tea, and it is made of young buds. If you choose to brew green tea with high-temperature boiling water, it will destroy the leaf structure of green tea, resulting in only one result - the tea soup is bitter and astringent.
Therefore, in general, famous green tea is brewed with water at a low temperature of 70-80, and other green teas are brewed with a starting point of 95-100.

First of all, you have to confirm what kind of magnet it is, wind turbines need to use better rare earth permanent magnets, taking samarium cobalt magnets and NdFeB magnets as examples: 1) Samarium cobalt magnets: low temperature is not limited (can not be used with liquid nitrogen), as long as the use temperature does not exceed 350, the magnetic part will not affect the normal use; When the Curie temperature is reached at 800 degrees, the samarium cobalt magnet is demagnetized and has no magnetism. >>>More
The temperature at which water boils is called the boiling point of water, and we usually say that "the boiling point of water is 100", which means that it is at one atmospheric pressure (standard atmospheric pressure). >>>More
