Can I drink old black tea?
Question 1: Can I drink old black tea? Old black tea can be drunk for 30 minutes, and its efficacy is not diminished, provided that the preservation method is correct.

1. tin can storage method: tinplate double-cover colored tea supplied in the market is selected as the container. Before storage, check whether the tank body and the tank cover are sealed to avoid air leakage. When stored, dry tea leaves should be canned and the cans should be tightly packed. This method is convenient to use, but it is not suitable for long-term preservation.

2. Hot water bottle storage method: choose a hot water bottle with good warmth as a container. Put the sun-dried tea leaves into a bottle and fill it up to reduce the air retention in the bottle. Cover the bottle mouth tightly with a cork, seal the brim with white wax, and then wrap it with tape. Because there is little air in the bottle and the temperature is stable, this method is also effective and simple.

3. Storage method of the ceramic jar: select a dry and sealed ceramic jar, wrap the tea with kraft paper, put it around the jar, put a lime bag in the middle, put the tea bag on it, and cover it tightly with a cotton bag after filling the jar. Lime should be replaced every 1-2 months. This method makes use of the hygroscopicity of quicklime, so that tea leaves are not affected by moisture, and the effect is good, and the quality of tea leaves can be maintained for a long time, especially for some precious tea leaves such as Longjing Banner and Bangdafang.

4. Packaging bag storage method: firstly, wrap the tea leaves with clean and odorless white paper, then wrap them with a piece of kraft paper, then put them into plastic food bags without air holes, gently squeeze out the air in the bags, then tie the bag mouth tightly with a soft rope, take a plastic food bag, cover it outside the first bag, similarly gently squeeze out the air in the bags, and tie the bag mouth tightly with a rope; Finally, put it into a dry, odorless and airtight iron cylinder.

5. Low-temperature storage method: the method is the same as "food bag storage method", and then the tea with tight bag mouth is put in the refrigerator. The internal temperature can be controlled below 5 degrees Celsius and can be stored for more than one year. This method is especially suitable for storing famous tea and jasmine tea, but it is necessary to prevent the tea from getting wet.

6, charcoal sealed storage method: using charcoal to absorb water to store tea. First burn the charcoal, immediately put it out with a brazier or an iron pot cover, dry it, wrap it in a clean cloth, and put it in the middle of a crock to make tea. The charcoal in the cylinder should be replaced in time according to the situation in Hu Chao.

Question 2: Is the older the aged black tea, the better? No, it depends on the way it is preserved. The longer the suitable environment, the better. A Taobao shop in St. Qingyun has been in existence for five years. The Pu 'er in it is not bad for three years, but after all, it is not cheap for three years. I wonder if it's sold out. If you don't have it, you still have to buy it, otherwise you will only have Dahongpao.

Question 3: Can old tea be drunk? Old tea can be drunk if it is not mildewed, but for green tea such as Longjing, it will turn yellow and its quality will decline. As you said, the situation may be well preserved, the taste is mellow, and it is not as rich as new tea; There is no basis for saying that old tea is not moldy, but it has special effects. Longjing belongs to green tea. Chlorophyll and polyphenols in tea will slowly oxidize if left for too long, which is not conducive to the quality characteristics of Longjing. Black tea such as Pu 'er tea is different. Through microorganism and extracellular enzyme fermentation, the quality of black tea is promoted. This process takes a certain amount of time and will also form some unique substances of black tea. But if it takes too long, the nutrients in tea will definitely be consumed. In fact, you still have to find something that suits your taste, and the right one is the best!

Question 4: Some people say, "Choose black tea, choose aged black tea. The new black tea has a rustic flavor. " Excuse me: Is this view correct? Personally, I don't think it can be so conclusive. The new black tea smells better. I haven't played the name of old black tea when I sell black tea. They are usually sold out before they get old. But bright red tea has a high fire smell, so it will be better to drink it after a while. But it can't be aged until the next year, so the aroma is easy to fade. The word "fishy smell" can only be said that the race of Zhengshan is not good enough. Good camellia has no earthy taste, but it smells like mud. I don't know if this answer will be satisfactory!

Question 5: Can I drink aged tea? According to the situation, some teas just need to be preserved for a long time.

Supplement: Tea refers to the leaves or buds of tea trees. Alias tea? (Ji m:), Ming,? F (chu γ n) is a shrub or small tree of Camellia, with or without hairless twigs. Generally, it refers to the leaves of the evergreen shrub tea tree that can be used to make tea, and the drinks brewed with these leaves, and later it is extended to all herbal teas brewed with flowers, leaves, seeds and roots of plants, such as "chrysanthemum tea"; "Herbal tea" brewed with various medicinal materials is also called Leiya in China literature. Some countries also use tea made from leaves of other plants, such as fruits and herbs, such as "fruit tea". The leaves are leathery, oblong or oval, and can be directly soaked in boiling water. It is divided into six categories according to varieties, production methods and product shapes. Tea beverage is called one of the three largest beverages in the world. Tea contains catechins, cholesterol ketone, caffeine, inositol, folic acid, pantothenic acid and other ingredients, which can improve human health. The hometown of tea is in China, and drinking tea began in China.

Question 6: Can I drink old tea? Yes, and the longer the tea, the more valuable it is.

Question 7: Can I drink aged Pu 'er tea? The older Pu 'er tea is, the better. The more fragrant it is, the more valuable it is. Many people like to collect Pu 'er tea. But if it is not well preserved, it will be moldy. Generally speaking, moldy tea means that tea is bad and cannot be drunk. Is there anything special about Pu 'er tea? Let's look at the answer in this article. Q:? Shame. What should I do? Also, what should you do if you judge that Pu 'er tea is moldy? A: It's better not to drink! It's not worth it if it's bad for your health Keep Pu 'er tea in a dry environment! It's best not to let it get moldy, or it will lose its value! Smell it or soak it to see if it smells musty. Generally, Pu 'er tea smells musty, but it is different from musty. The four keys to selecting Pu 'er tea are "clear, pure, upright and healthy": the first is to smell its taste. No matter whether Pu 'er tea is raw or cooked, old or new, good or bad, shape or price, the first thing to smell is tea. After aging and fermentation, Pu 'er tea will definitely smell stale, but it should not smell musty, indicating that the space in Chen Fang is humid or too humid and not ventilated. The so-called old but not moldy, the old taste will disperse with the hot air when making tea, and the moldy taste is the smell of tea that goes bad and moldy from the inside out; The second is to simply distinguish its color. Smell the tea before brewing to see if it is clear (no peculiar smell, no peculiar smell), and then soak it. Pu 'er tea is stored in normal environment, even if it is stored for 30 years, 50 years, or even 100 years, the color of tea (tea soup) will never turn black and will not produce strange smell; Third, put it in its original place, and store Pu 'er in a clean and ventilated environment; Fourthly, tea is good at absorbing the nearby flavor, and the washed tea gas can judge the aging environment and oxidation time of tea. At present, the Pu 'er tea market is not perfect enough, few tea merchants have the ability to identify Pu 'er tea, and many tea shops can't tell its true quality. Driven by interests, some people take the name of time-honored brand, and Pu 'er, a treasure that has existed for twenty or thirty years or even fifty or sixty years, is getting drunk more and more. There are also many tea merchants who store their tea products in a dark and high humidity environment to accelerate aging. Artificial watering often leads to mildew and deterioration of tea leaves. After the rapid deterioration of tea leaves, air-dry the tea cakes, and you can get wet-stored tea that looks like aged Pu 'er in a short time. There is no musty smell, and the tea soup after making tea is reddish brown and has no peculiar smell ~ then you can rest assured to taste it. It looks moldy. Maybe it's your illusion. Because the buds of Pu 'er tea are extremely rich and dense, the processed tea leaves are densely covered, which at first glance looks a little moldy. It is said that it would be nice if it were white hair. Pu 'er tea paste has its unique aging cycle. Theoretically, the time is about 60 years. After the transformation of internal substances in tea cream, with the deterioration of crystal water, the quality of tea cream showed a downward trend. The paste has weathered, too? Are you kidding? On the one hand, don't trust the so-called high-aged tea cream in the market; On the other hand, even if there is, the nutrients contained in it are lost and have no drinking value. What needs to be pointed out here is that in recent years, some Pu 'er tea paste products have appeared intermittently among the people, and even some so-called old tea cream have appeared. Basically, they are all modern imitations made by the cauldron boiling method, which is very different from the production technology of the royal teahouse in Qing Dynasty. Several so-called old tea cream circulating in the market in recent years were tested by relevant institutions, and almost all of them were found to have residues of modern pesticides, which proved that these tea cream were made from current tea seeds, and the production technology was far from that of Pu 'er tea paste made by Qing Palace Imperial Tea Room. ? I believe that through the explanation of this article, everyone will understand this. I remind you again, don't drink Pu 'er tea if it is moldy, but think about your health. More specifically: 1.

If the old green tea is moldy, you can't drink it.

Black tea, white tea, black tea, the older the better.
