How often is it appropriate to change the brewed tea?

Different types of tea have different degrees of brewing resistance

1. Very delicate high-grade tea is not resistant to brewing, and it generally has no tea flavor after brewing 2 times.

2. Ordinary red and green tea can often be brewed 3-4 times.

3. The degree of brewing resistance of tea is related to the tenderness of tea, but more importantly, it is determined by the integrity of tea after processing. The finer the processing, the easier it is to brew the tea juice, and the coarser and older the complete tea leaves, the slower the tea juice brewing out.

4. But no matter what kind of tea, the first brewing and leaching amount can account for more than 50% of the total soluble matter, and the second brewing of ordinary tea is generally about 30%, the third time is about 10%, and the fourth time is only 1-3%. From a nutritional point of view, vitamin C in tea

and amino acids, after the first brew, 80% is leached, and after the second brew, more than 95% are leached. Other active ingredients such as tea polyphenols.

Caffeine and other substances are also the largest leaching amount for the first time, and after three brews, the full amount is basically leached.

5. It can be seen that the brewing times of general red, green and flower tea are usually three times. Oolong.

Due to the large amount of tea during brewing, it can be brewed several times; Tea bags processed and packaged from black crushed tea are usually suitable for one-time brewing because they are easy to leach.

The brewing of tea leaves does not stipulate that the tea leaves should be changed within a certain period of time, but is mainly defined according to the taste of the drinker and the different types of tea. The key to the brewing of tea is to worry about the problem of pesticide residues in tea, experts said that the pesticide content of spring tea is much less, and the pesticide residues of summer and autumn tea are relatively more. How to tell whether tea contains pesticides Just by looking at the shape, color, and smell of tea, it is almost impossible to distinguish whether tea has pesticides, and it can only be tested by professional testing.

However, for the vast majority of tea, it is normal to contain pesticides, as long as the pesticide residue is controlled within the national standard, it is a safe product for the human body. Other ingredients, such as lead in tea, are almost insoluble in tea soup when brewed, and most of the residual pesticide components contained in tea brewed with ordinary water within two hours cannot be brewed. Therefore, there are two things to keep in mind when drinking tea:

One is not to chew the tea leaves, and the other is not to change the tea leaves from morning to night with a cup of tea. It is still relatively safe to drink tea in this way.

The number of brewing times of various tea leaves is different, and whether to wash the tea or not should be determined according to the tea variety. Generally, green tea is a non-fermented tea that should be used no more than 4 times. If a cup of tea is brewed from the morning, it is not advisable to continuously add boiling water and drink it until the evening.

The best brewing trend is to make a cup of tea in the morning and remake a cup of tea in the afternoon every day, which is both fresh and tea-flavored.

Semi-fermented teas like white tea, yellow tea, and green tea can be brewed five to seven times, and this type of tea is bright in color, suitable for brewing in a glass, with a certain ornamentality. Fully fermented teas like black tea and dark tea can be brewed more times, after all, the degree of fermentation is relatively high, and there is no problem in brewing about 10 times.

Due to the long processing time and complex process, oolong tea, Tieguanyin, Dahongpao, etc., will inevitably be mixed with dust and dirt during the production process. It is best to wash it before drinking, which helps to remove impurities on the surface of the tea leaves, and the leaves of this type of tea are relatively thick, and in boiling water, substances beneficial to the human body will not dissolve immediately.

Green tea is generally brewed three to four times, and Pu'er Tieguanyin can be brewed seven or eight times.

It also depends on the length of the water, and you can make tea several times.

Depending on the mood or the scene!

When drinking tea by yourself or by people who are very familiar and close to you, the tea soup is so light that you can change it when you can't drink it;

If you are entertaining guests, no matter how many times you have brewed the tea leaves in the bowl, be sure to replace it with new tea to show etiquette and respect.

Tea leaves generally have no taste of tea after 2 to 3 times, so tea leaves generally need to be replaced after 2 to 3 times. To sum up, look.

According to the taste of tea soup, different teas have different brewing resistance.

Green tea 1 3 brews.

About 5 brews of black tea.

Pu-erh tea 8 10 bubbles.

The brewing resistance of tea is also affected by the brewing equipment and the amount of tea, and the specific problems still need to be analyzed in detail, and there is no conclusion.

Brewed tea, generally within a day without the amount, is drinkable, this will not cause deterioration, but using a thermos cup to hold tea, may cause the thermos cup not to keep warm, I hope my advice will help you.

1. Don't drink tea water overnight, there will be a lot of nitrite in it, and it will be spoiled in summer.

2. Green tea should not be brewed too many times, the water temperature is 80 degrees is the best, and do not soak in hot water for a long time, it is easy to soak some heavy metals in the tea into the tea, which is not good for the body.

3. If it is black tea or oolong tea, you can brew it several times, and the color of the tea and the concentration of the tea soup depend on your own acceptance, and decide whether to rebrew.
