1. What kind of tea set is the best for making tea?
At present, the common teas are porcelain, pottery (mainly purple sand ware), glass, plastic and so on. When brewing black tea and oolong tea, I will choose pottery, because from the perspective of tea tasting, porcelain and pottery are the best, with good heat preservation, good color and fragrance, beautiful shape and artistic appreciation value. But when brewing green tea, especially Biluochun and Yinzhen, I usually use a glass tea set, which can present the beauty of light fog, green and blossoming tea buds in the cup. As for enamel and plastic tea sets, although they have the advantages of portability and durability, they are generally used for temporary thirst quenching.
2. Does the water quality have an effect on making tea?
There are many kinds of water and their properties are different. Different kinds of water have different effects on the quality of brewed tea soup because of different dissolved substances. Tea is natural and pure, and improper use of water will bring you a lot of regrets. Lu Yu's Tea Classics says:? Its water is used for mountains, rivers and wells. Its landscape, milk-collecting springs, stone pools, overflowing, its waterfalls rushing, don't eat? Those rivers take people far away, and those wells take more people away. ? This shows that it is best to use spring water to make tea, and the spring water should flow out slowly. The best spring water is the one with the least calcium and magnesium compounds. Making tea in river water is generally not ideal, and well water is not as good as river water. As for rain, it is generally pure. But the time of rain is different, and the water quality is different. Autumn rain is the best, followed by plum rain and thunderstorm is the worst.
3. What is the best temperature and time for making tea?
The control of tea temperature mainly depends on what kind of tea to drink. Green tea, especially all kinds of tender buds and leaves, such as silver needles and hairy tips, cannot be brewed with boiling water at 100℃, and 80℃ is generally appropriate. It is appropriate to brew all kinds of scented tea and black tea with boiling water at 100℃.
4. How should tea be stored?
Tea adopts advanced preservation technology, which can ensure that tea does not deteriorate for a long time. But the best preservation condition is room temperature, dark and odorless environment. If the water content of tea is high or it has been wet, it can be dried or fried at about 80℃ and then stored. Large quantities of tea can be divided into 0, 25-0 and 5 kilograms, wrapped in white paper and put into dry pots and cans, and some desiccant can be put in the middle of the bottom layer. The type of desiccant may depend on the availability of tea and materials. Green tea can be stored with massive deliquescent lime, black tea and scented tea can be stored with dry charcoal, and color-changing silica gel can also be used if conditions permit. The lids of cans and jars should be covered with multi-layer toilet paper and tightly pressed to prevent moist air from entering. If the amount of tea leaves is small, it can also be wrapped in paper, sealed with two layers of polyethylene food bags, placed in biscuit boxes and covered tightly. In order to prevent tea from absorbing odor, it is forbidden to put tea together with substances with serious odor, such as moth balls, soap, perfume, cigarettes, etc. Newly bought tea cans often have a layer of oil stains on the metal surface in the cans, which must be wiped to dry, and then wiped with a small amount of waste tea leaves to remove the odor before filling tea.
5. How much tea and water should I put in making tea?
To make a good cup or pot of tea, we must first master the amount of tea. There is no uniform standard for how much tea to use each time. It mainly depends on the type of tea, the size of the tea set and your drinking habits. If you are used to making tea in cups, I suggest you use teabags. 2 grams of tea bags per bag, brewed in ordinary cups, just the right amount, regardless of the amount of tea, you can drink a cup of natural and pure good tea. If you use a pot, master it according to its size. Generally, the ratio of tea to water is controlled at 1:50-60, that is, about 3g of dry tea is put into each cup, and 150-200ml of boiling water is added.

6. How about drinking tea and taking medicine?
Can you drink tea and take medicine? You can't generalize. In most cases, you don't advocate taking medicine with tea, especially western medicines containing iron, such as ferrous sulfate, ferrous carbonate, citric acid, ferric amine and aluminum hydroxide. When polyphenols in tea soup combine with metal ions to precipitate, they will reduce or lose their efficacy. In addition, tea contains caffeine (also known as? Caffeine ) has an exciting effect, so when taking sedative, hypnotic and antitussive drugs, it is not advisable to take them with tea to avoid drug conflicts and reduce the efficacy. When taking preparations, such as protein and starch, it is not advisable to drink tea. Polyphenols in tea can combine with it and reduce its activity. Some alkaloid preparations and drugs such as atropine and aspirin should not be taken with tea. Taking furazolidone and methyl, drinking a small amount of tea will cause insomnia, and drinking a lot of tea will raise blood pressure. It is generally believed that drinking tea should be stopped within 2 hours after taking the medicine. However, when taking vitamins, stimulants, diuretics, drugs for lowering blood fat, lowering blood sugar and raising white blood cells, you can generally take tea. For example, drinking tea after taking vitamin C, green tea is rich in catechins, which can help the human body absorb and accumulate vitamin C. Moreover, tea itself has the functions of excitement, diuresis, lowering blood fat, lowering blood sugar and raising white blood cells. When taking such drugs, tea has a synergistic effect.
7. White precipitate sometimes appears when green tea is brewed. Is there something wrong with tea?
The phenomenon of white precipitation when brewing green tea is mainly caused by water, which proves that the water you use is hard water, that is, there are too many compounds containing calcium and magnesium in the water. The main component of this white precipitate is calcium oxalate. Because there is a high content of oxalic acid in tea, it can combine with calcium ions in water to form insoluble calcium oxalate, and even precipitate, which has nothing to do with the quality of tea.
8. The surface of black tea will be turbid after cooling. What is this?
The surface of black tea will be cloudy after cooling. What is the academic name of this turbidity produced by cooling black tea? Cold and muddy? This turbidity is mainly caused by the combination of caffeine, theaflavins and thearubigins. Is the tea soup normal? Cold and muddy? Phenomenon is generally the appearance of good tea quality, which can be used as a method to choose black tea.
9. Is Kuding tea real tea?
Real tea leaves are processed from fresh leaves picked from plants of Theaceae and Camellia. Ilex kudingcha belongs to Ilex, so it is not tea strictly. Kuding tea is made from Kuding tea through tea processing. According to clinical experiments, Kuding tea has good effects of diminishing inflammation and relieving pain, cooling and detoxifying, lowering blood fat, lowering blood pressure and losing weight, and is known as health tea, beauty tea, antihypertensive tea and longevity tea.
10. I am not familiar with tea. Can you give me some advice on what kind of tea is best for me?
Generally speaking, the nutrition and medicinal components of delicate and famous tea are higher than those of coarse and old tea, and green tea is higher than black tea. For specific individuals, I offer the following suggestions according to the efficacy of various teas. You should be able to find out which kind of tea suits you: people who are weak should drink black tea, and add some sugar or milk to the tea to increase energy and supplement nutrition. Ginseng tea, Korean ginseng tea and ginseng tea have the effects of nourishing and strengthening the body, which is very helpful to the weak; Young people are in the developmental stage, so it is better to drink green tea. Women can drink scented tea before and after menstruation and menopause, especially jasmine tea, which has the effects of soothing the liver and relieving depression, regulating qi and regulating menstruation; People who want to lose weight can drink more oolong tea. People who are often exposed to toxic substances can choose green tea as a labor protection drink.
1 1. When is the best time to drink tea?
Drinking a cup of tea in the morning helps to refresh yourself, and drinking tea in the workplace can eliminate fatigue, enhance vitality and improve thinking and judgment. Drinking tea while smoking can reduce the toxicity of tobacco oil and nicotine, and drinking tea while watching TV can help restore vision and alleviate the harm of weak radiation. As mentioned above, the most suitable time for drinking tea varies from person to person, from environment to environment, and from working conditions. Drinking tea at a certain time is not necessarily beneficial. Drinking tea for quenching thirst is more casual, and you can drink it when you are thirsty.
12. Can strong tea really sober you up?
? Drinking tea can relieve alcohol? Everyone says so, but many people are not sure whether they can really solve the problem. In fact, drinking strong tea can really relieve alcohol. After drinking, people mainly rely on the hydrolysis of alcohol by human liver to hydrolyze alcohol into water and carbon dioxide, which requires vitamin C as a catalyst. Therefore, drinking a few cups of strong tea or oolong tea at a banquet or after drinking can supplement vitamin C on the one hand, and caffeine in tea has diuretic effect on the other hand, which can make alcohol excreted quickly. Drunk people often have symptoms such as dizziness, headache, and uncoordinated body functions due to cerebral palsy. Drinking strong tea can stimulate the central nervous system of cerebral palsy, effectively promote metabolism, and thus play a role in sobering up. If you drink too much, you might as well drink a cup of ginseng tea. Ginseng tea is made by mixing high-quality China people with green tea, and some people participate in the functions of nourishing and strengthening green tea and promoting metabolism. And the hangover effect is better.
13. Is the tea hot or cold for health?
Answer: Many people like to drink hot tea. As we all know, drinking strong tea above 80℃ will cause tannic acid in tea to precipitate in the burned part of esophagus, which will constantly stimulate the epithelial cells of esophageal wall and make them mutate. Mutant cells can evolve into tumor tissue after a large number of proliferation, which makes people suffer from digestive tract cancer. It is best to cool the boiled tea below 70℃ before drinking, that is, when touching a ceramic or glass teacup with your hands, it is most suitable when it is no longer hot.
14. Why can drinking tea refresh you? Are there any side effects?
Caffeine contained in tea can excite the nerve center and produce refreshing effect, and its excitement depends on the dosage. Moreover, caffeine can also eliminate fatigue and resist the toxic effects of alcohol, nicotine and morphine. After all, the side effects of caffeine are temporary. Caffeine does not accumulate in human blood, but is usually excreted with human metabolism within a few hours. If you want a better refreshing effect, you'd better drink American ginseng tea.

15. Sometimes drinking too much tea leads to insomnia. Is there a solution?
Caffeine and flavanol in tea can promote the activity of adrenal gland and prevent the degradation of catechol in blood. In addition, it can also induce the biosynthesis of catecholamine, which can promote excitement. If you are a person who is prone to insomnia when drinking tea, please don't drink tea or strong tea at night to ensure a good dream.
16. Will you really get drunk after drinking tea?
Tea contains compound polysaccharide catechin, which is an effective water-soluble component for lowering blood sugar. When drinking tea on an empty stomach, people's blood sugar is already very low, and then taking compound polysaccharide and catechin will further reduce people's blood sugar, which will cause dizziness, palpitation, weakness of hands and feet, trance and other symptoms. Tea? . If you don't want to put down the teapot, you can have some snacks to get rid of it? Tea? .
17. How to identify the quality of tea when buying tea?
In fact, when identifying the advantages and disadvantages of tea, we should first pay attention to the following two aspects: one is dryness, and the other is freshness. When buying bulk tea, you can hold the tea bar with two fingers. If it can be ground into powder, it means that tea is relatively dry, and its water content is about 6-7%, which is a qualified standard. If it can't be ground into powder, it can only be ground into fine pieces, indicating that the tea has absorbed water, and the dryness is insufficient, and the water content is often above 9%. It is not suitable to buy this kind of tea with high water content. New tea has a unique new tea fragrance, and the aroma and taste have a fresh feeling. From the appearance color, we can preliminarily identify whether the tea leaves are fresh. New green tea is dark green and shiny, and black tea is shiny. In addition, grab a dry-smelling tea, and all the products without musty smell are normal products. When buying small packages of tea, look carefully or ask about the packaging date. Generally, small packaged tea leaves are easy to absorb moisture and deteriorate, and the shelf life is more than one year. In addition, pay attention to identify the quality, integrity and moisture-proof performance of packaging materials when purchasing.
18. Tea leaves will smell during storage. How to deal with and prevent?
Tea has a strong adsorption, especially the olefinic substances it contains. Therefore, when storing tea, it is best not to store tea in an environment with peculiar smell, and the packaging materials must not have peculiar smell. At the same time, the packaging of tea must be sealed to reduce contact with the external environment.
19. How much tea should people drink every day?
There is no strict standard for the amount of tea to drink, which varies from person to person. Generally speaking, healthy adults who have the habit of drinking tea should drink 6- 10g every day and brew it 2-3 times. People who engage in physical activities and eat a lot drink about 20 grams of tea every day; People who eat greasy food and have a large amount of alcohol and tobacco can also increase appropriately; For the elderly with blood deficiency and spleen and stomach deficiency and cold, pregnant women and children should appropriately reduce the amount of tea.
20. How about strong tea?
Strong tea refers to excessive tea (usually 3-4 grams per cup) when making tea. Drinking strong tea is good for people with damp heat, excessive alcohol and tobacco, greasy meat, urination, oral inflammation and sore throat, but I advise others not to drink strong tea.
2 1. Can I have herbal tea and overnight tea?
From the point of view of nutrition and hygiene, I think overnight tea is generally not suitable for drinking. As for Leng Cha, if it doesn't go bad, you can drink it. But you can't put a part of the tea soup you have been drinking for a long time before drinking it. At present, all the canned teas on the market belong to Leng Cha, and they can only be drunk after strict sterilization. It should also be noted that elderly people with weak qi and blood and deficiency of spleen and stomach cannot drink herbal tea or overnight tea.
22. How many times should I make a cup of tea?
This is a very general question, and the impact resistance of different teas is different. Generally, black tea, green tea and scented tea should be brewed for three times, and after three times, the tea fragrance will be gone. Oolong tea can be brewed 5-6 times because of its large amount of tea.
23. Why is tea soup bitter? Why do different teas have different degrees of bitterness?
The bitterness in tea soup is mainly caused by polyphenols contained in tea and anthocyanins caused by caffeine. The bitterness of tea is determined by the variety, season and production technology of tea. For example, tea trees with small leaves contain more polyphenols, and the anthocyanin content of summer tea is higher than that of spring tea. In the production process, polyphenols and anthocyanins are transformed more, and their bitterness is low or not, while insufficient transformation produces bitterness.
24. How about drinking tea that has been soaked for a long time?
There is a great difference in the chemical composition between tea that has been brewed for a long time and tea that has just been brewed. Polyphenols and amino acids in tea are oxidized and polymerized, and the taste becomes worse. Lipids and carotene are hydrolyzed and oxidized to produce sour taste, vitamins are oxidized, aroma substances are volatilized, the content of heavy metals in tea soup increases, and the content of bacteria in tea soup increases after long-term exposure to air. So tea should not be soaked for a long time.
25. There are often bubbles on the surface when making tea. What are these bubbles? Can you tell the quality of tea from the amount of foam?
Tea leaves foam in the brewing process, mainly because tea leaves contain tea saponin, which has strong foaming ability. However, its content in tea is very low, which has no effect on the quality of tea, such as color, aroma and taste. Therefore, we can't judge the quality of tea by how much it is brewed.
26. Can adding tea leaves to food achieve the same effect as drinking tea?
Generally, only water-soluble substances are consumed when drinking tea, and the water-soluble substances in tea only account for about 40% of the dry weight of tea. Most water-insoluble substances are mainly dietary fiber, protein, lipids, pectin, starch, fat-soluble vitamins and so on. These are not used when eating. Drinking tea directly will be more beneficial to your health.

27. What are the main applications of tea in food?
This question cannot be answered in a few words.

I can only say a few: among them, tea is the most important natural antioxidant, which is widely used in animal and vegetable oils, baked goods, aquatic products, meat products, seasonings, beverages and so on. Adding tea as a food ingredient improver to food is more and more popular among consumers. If tea leaves are used as tea bread, because tea leaves contain some special chemical components, it can increase the volume of bread and increase the anti-corrosion ability of bread, so the tea bread made is not only fragrant and delicious, but also very loose and storage-resistant. In addition, tea leaves are also used as natural health food additives, such as tea polyphenols extracted from tea leaves and added to other foods to make anti-cancer and anti-aging health food. If you think the above content is not enough, please continue to contact us.
28. Is there any other use for tea residue after making tea?
Most people will throw away the tea residue after drinking tea. In fact, tea residue is rich in dietary fiber, inorganic substances, water-insoluble protein, fat-soluble vitamins and so on. These substances are not used. Some Japanese experts devoted to tea research have established with doctors and chefs? Tea and Cooking Research Association? Advocates are not only talented? Tea? More? Tea? In short, it is to eat tea residue, that is, the tea residue is slightly heated and dried in an electric oven and stored for later use, and various dishes are cooked in batches like ordinary vegetables. Pass? Tea? You can eat about 1 1- 18% dietary fiber, which is especially necessary after eating a high-fat or high-cholesterol diet, and is of great significance for preventing colon cancer, treating diabetes, constipation and lowering cholesterol.
-"The Application of Tea in Food" by Yang Xiaoping
I want to cook some tea at home. Any good suggestions?
Of course there is. In fact, home-made tea food has become very popular in Japan. For example, in recent years, there is a fashion of eating tea and rice in Japan. When cooking, scented tea is used instead of clean water, which makes the rice have attractive natural flower fragrance and tea fragrance, and can also preserve health, eliminate diseases and prolong life, especially in summer and autumn, and can dispel wind and dissipate heat and prevent dysentery. Cooking fish with tea can relieve fishy smell, and cooking beef with tea can quickly rot and increase flavor; Noodles made of tea do not paste the pot and taste fresh; There are also tea chicken soup, tea boiled eggs, tea steamed bread and so on. Clever use of tea to prepare food can not only stimulate appetite, be beneficial to health, but also add some interest to life, which is really worth advocating.
30. Will the quality of tea be affected if it is stored for a long time?
The main factors affecting the quality of tea are temperature, light and humidity. If these factors are reduced or eliminated by correct storage methods, the quality of tea can be guaranteed for a long time. However, if it is stored improperly, the chemical composition of tea will change obviously, mainly in the following aspects: (1) has stale taste; The soup turns brown and black; The concentration, convergence and freshness of the taste decrease.
3 1. Why can't I make tea with cold water?
It is important for tea to smell its fragrance, observe its color and taste. The volatilization of aroma is the aromatic substance brought out by steam evaporation when hot water is brewed. Its color and taste are determined by the amount of water extract. Because some components in tea are hot-soluble, only by brewing with hot water can we quickly understand the color, fragrance and taste of tea.

38. Is it better to make tea with pure water or tap water?
Urban tap water is generally disinfected and filtered, which is relatively clean and hygienic and suitable for drinking. However, sometimes excessive chloride disinfection will have an odor, and minerals in water have an impact on the quality of tea. For example, when high-priced iron oxide contains 1ppm, the quality of tea soup is not good, when calcium reaches 4ppm, the taste becomes bitter, and when magnesium reaches 2ppm, the tea soup becomes weak. Pure water basically contains no other dissolved substances except CO2, which does not affect the taste of tea and is beneficial to tea tasting. Of course, it is best to use spring water to make tea.
39. Can you provide some tea-making skills?
Of course. Good tea, good water, and proper brewing are needed to make a good pot of tea.
