How to store tea and how to preserve tea leaves

It is best to use a drying oven to preserve the tea leaves. Because the temperature of the drying oven is stable and the air is also isolated, the tea leaves will not be damp or oxidized when stored in the drying oven.

Tea polyphenols, polyphenols, vitamin C and carotene in tea are highly oxidized, so ambient temperature, relative humidity, odor, light, air and microorganisms will affect the quality of tea. In order to keep it from deteriorating, it must be careful to avoid high temperature, high humidity, light and oxygen.

The materials used to preserve tea in daily life are aluminum-platinum composite bags, utensils, and a combination of the two. Tin pots are preferred, but other clay pots, metal boxes, etc. are also acceptable. It is best to put an appropriate amount of tea preservative in the packaging bag to preserve the tea leaves in a composite bag.

Of all the tea leaves, green tea is best stored in the refrigerator. If the storage time is short and you need to drink it at any time, you can put the green tea in the refrigerator and adjust the temperature of the refrigerator to about 5 degrees Celsius; However, if it is an unopened tea leaf and you want to keep it for more than a year, you should put it in the freezer.

In addition, in order to prevent tea from becoming the "deodorant" of the refrigerator, the tea should be sealed and packaged before being put into the refrigerator, and a sufficient amount of special preservative should be filled into the packaging bag, and the packaging material should be preferably an aluminum foil composite bag.

It should be noted that after taking out the tea leaves from the refrigerator, do not open the package immediately, the correct way is: take out the tea leaves in the refrigerator and let it slowly heat up, and after it rises to room temperature (usually every other day), open the packaging bag, and then brew and drink. And it is best to drink it in half a month.

Compared to green tea, oolong tea, black tea, and jasmine tea do not have to be stored in the refrigerator. Due to the relatively low content of polyphenols in oolong tea and black tea, the aging and deterioration rate is slower and easy to store. Flower tea has a strong floral aroma, and storage at low temperature will inhibit its aroma and reduce the freshness and concentration of the aroma.

Therefore, as long as it is placed in a dry, airtight, light-proof container and odor-free container, it can be stored for a long time. Pu-erh tea is best stored at room temperature and does not need to use desiccant.

The storage methods for different tea leaves are as follows:

1. The preservation of green tea needs to be kept away from high temperature, light, and anti-oxidation, and it is best to keep it in the refrigerator for refrigeration, and if it is to be stored for more than a year, it needs to be put in the freezer. Before putting the tea in the refrigerator, an appropriate amount of tea preservative should be filled into the sealed bag, preferably in aluminum foil.

2. Because black tea is fermented, it is much easier to preserve than green tea, just put it in a closed container, pay attention to moisture-proof and high-temperature protection, if possible, it is recommended to use clay pots, purple sand jars for preservation, and if you use glass bottles, you should pay attention to prevent direct sunlight.

3. The preservation of black tea needs to pay attention to dryness, moisture-proof, ventilation, in daily life, black tea is easy to get damp, and needs to be stored in a dry and ventilated place without peculiar smell.

4. White tea is different from green tea, it does not need to be stored in the refrigerator, as long as it is stored in a dry container, ventilated, dry and protected from light.

5. Oolong tea is relatively dry, but it is easy to absorb moisture and odor, so you need to pay attention to it when preserving.

6. The preservation method of yellow tea is similar to that of oolong tea, and it is necessary to pay attention to moisture and odor intrusion.

Extended Materials. Choice of container when making tea:

1. Choose a transparent glass for green tea.

West Lake Longjing, Dongting Biluochun, Junshan Yinzhen, Huangshan Maofeng and other delicate and precious green tea, suitable for drinking in a transparent glass, easy to observe the slow stretching, swimming, and changing process of tea in the water, people call it "tea dance".

Medium and high-end green teas such as first- and second-class fried green, pearl tea, and roasted green tea focus on taste or thirst quenching, and can be brewed in a porcelain cup. Medium and low-grade green tea contains a lot of fiber, is resistant to brewing, and has a strong tea flavor, which is suitable for brewing in a teapot. If you use a teapot to brew delicate and famous tea, because there is a lot of water, it is not easy to cool down, and the tea will be ripe, so that the tea will lose its fresh fragrance.

2. Choose white porcelain or glass bowl for black tea.

On the one hand, the soup color of high-grade black tea is required to be red, and the white or milky white porcelain can truly reflect the soup color of black tea, which is convenient for tea guests to watch. On the other hand, brewing with a gaiwan can bring out the inherent aroma and taste of black tea, without compromising the quality of tea, and it is very convenient for tasting and smelling tea.

3. Oolong tea should be purple clay pot.

For Minnan oolong, especially Tieguanyin, in addition to tasting tea soup, it is also very important to smell the fragrance and appreciate the bottom of the leaves. For Northern Fujian Oolong and Guangdong Oolong, brewing with a gaiwan can highlight the original taste and aroma of tea, easy to observe the bottom of the leaves, and brewing with a purple clay pot can make the tea soup mellow and the aroma will not disperse.

In life, we often encounter such a problem, some tea leaves are damp or spoiled when they are put away, if the tea is damp or tasteless, then the brewed tea, the taste is really bad. How can I prolong the freshness of this tea? What is the best way to store tea?

Today, I will talk to you about the problem of storing tea, no matter what kind of tea it is, it itself has been dried, so the storage environment of tea is very important. In a damp environment, tea leaves can easily absorb moisture, and at the same time, they will also absorb some peculiar smells. In this case, it is easy to change the composition of the tea, as well as the quality of this tea.

That's why we pay attention to tea storage. Of course, some good tea is also quite expensive, if the tea is damp or tasteless, this is a waste in itself, and this kind of problem must be solved.

The way tea is stored, in general, to remember these keywords, we must keep these key points in mind. It must be moisture-proof, sealed, pressure-proof, light-proof, and odor-proof. When we choose a container for storing tea, it is generally best to use tin cans, jars, and tinted glass bottles.

Because tea is afraid of light, you must remember not to use transparent glass bottles. You can also use iron cans, wooden boxes, bamboo boxes, etc., if you choose bamboo boxes, then it is not suitable for use in the dry north.

What is the best way to store tea? If you choose stainless steel tea cans, or iron cans to store tea, the problem to pay attention to here is that after putting the tea leaves into the container, you should tighten the lid to keep it sealed and block air from entering. Only by storing the tea in this way can the nutrients in the tea be better maintained.

Because this kind of method is relatively simple and easy to implement, it is favored by many tea lovers. Of course, there are many varieties of tea, in fact, in general, it is enough to do a few points, I hope these can help you.

What is the best way to preserve tea?

How tea should be preserved. Tea storage strictly prohibits tea from contact with peculiar smells: tea has a fragrance is one of the reasons why people love tea.

If the tea loses its original aroma and is replaced by other peculiar smells or even disgusting smells, then people will not want to drink it even if the other quality conditions are good. Tea is active and sensitive to other strong flavor products, especially pesticides, cigarettes, Chinese herbal medicines, soaps and other odor products have a strong absorption function, and it is easiest to absorb odors, so it is also very important to prevent tea leaves from coming into contact with odors when storing tea. Tea leaves are easy to absorb odors.

2. Do not have more water content in tea: how much water is in tea directly affects the decisive role of tea deterioration, and experiments have proved that in the process of tea storage, the speed of tea water absorption and moisture is related to the relative humidity of the surrounding environment. For example, the water content of tea leaves was measured after 10 days of exposure to different humidity conditions of the air, and the water content of tea rose to 42% under the condition of 42% relative humidity of the air; Under the condition that the relative humidity of the air is 57%, the water content of tea rises to; Under the condition that the relative humidity of the air is 90%, the water content of tea rises to.

If the dried tea leaves are exposed to the air during the rainy season, the water content of the tea leaves can increase by about 1% per hour. Therefore, to store the tea, the receptacle and the environment around the receptacle must be dry. Otherwise, even if the tea leaves are dry, they will absorb moisture and return to moisture due to the high humidity of the surrounding environment.

3. Prevent tea extrusion: In addition to pressed tea and various broken teas, most of the tea leaves are intact. Tea leaves are not broken, there are buds and leaves, and they remain intact, which is an important sign of good tea quality.

Therefore, except for special needs, tea leaves, such as Yunnan Pu'er tea Asluozhai, even if there are crumbs produced during processing, must be screened and removed. Because the tea is required to be dry during storage, most of the tea leaves are relatively loose, if they are squeezed, it is easy to become fragments, so that high-grade tea is misunderstood as low-grade tea, and when the soup is brewed, it also lacks ornamental value because of the many pieces. Therefore, it is inappropriate to use squeezing, pressing, and rubbing when storing tea.

4. Choose storage utensils: If you want to store tea well, it is also very important to choose good storage tools. The commonly used utensils are:

1) Purple sand clay pot, wrap the tea leaves with film paper and seal them, and then cover the lid of the clay pot, which is relatively sealed, and many tea houses are preserved in this way. (2) Put the box together in the refrigerator for preservation, so that the tea leaves are dry and odorless. Of course, you can also wrap it in a moisture-proof film paper and put it in the refrigerator.

There are already refrigerators dedicated to storing tea. (3) Buy a large glass tea caddy in the supermarket, this kind of jar has a rubber ring around the lid, which perfectly seals the internal tea leaves and is not breathable. Convenient and practical.

4) Moisture-proof box storage.

First: Generally speaking, it is best to use iron cans, jars, and colored glass bottles to store tea. Secondly, it is advisable to use iron cans, wooden boxes, and bamboo boxes, among which bamboo boxes should not be used in the dry north.

Plastic bags and cartons are the worst. Many teahouses choose purple clay pots, which wrap tea leaves in film paper. Once the lid is closed, the tea leaves are sealed.

Second: stainless steel teapot, tin plating is also a good tea container, you can directly put the tea leaves into the container and lid, which can play a sealing effect, so that the air can not enter, you can better maintain the nutrients of the tea, and the method of making tea is also very convenient.

Third: For the ordinary family, the amount of tea is not much, it can be stored through the box in the refrigerator, so that the effect of saving tea can rise to dry, no peculiar smell, (now tea, generally have a tea vacuum machine, after buying tea to help you vacuum, back to the refrigerator at home, as long as you don't open it is to put the gear to keep the original tea.) One thing to note, once opened, be sure to pay attention to the peculiar smell) can also be wrapped in moisture-proof film paper, and now in many developed places there are refrigerators dedicated to preserving tea, and the effect is better.

However, it is important to note that oolong, black, and jasmine tea do not have to be stored in the refrigerator. Due to the relatively low polyphenol content in oolong tea and black tea, the aging and deterioration rate is slow and easy to store. However, flower tea has a strong floral aroma.

Cryopreservation inhibits its aroma and reduces its freshness and concentration. Pu-erh tea is best kept at room temperature and kept in a ventilated and dry place.

Fourth: There is a relatively simple way to buy a large glass teapot in the supermarket, which is generally equipped with rubber rings around the teapot, which can achieve a perfect sealing effect, which is convenient and practical.

Tea containers should be kept away from light.

Direct sunlight can change the internal substance of tea, and the more obvious this change is when strong sunlight is directly irradiated. Therefore, white and translucent tea containers should never be placed in direct sunlight. If you want to use colorless transparent glass bottles for tea, be sure to cover the bottle wall with 1-2 layers of clean paper, seal it and put it in a cabinet or cupboard.

If you use cans, tubes, and boxes of tea, do not put them on a table or cabinet top or window sill that has seen light for a long time, so as to prevent light from affecting the quality of tea.

Tea containers should be kept in a dry place to prevent moisture.

The more water in the tea leaves, the more difficult it is to preserve the quality of the tea leaves, so the tea leaves cannot be damp. The container for holding tea, some are not necessarily completely sealed, placed in a dry place, and absorb moisture'The chances will be relatively small, which is beneficial for tea preservation.

Tea containers should not be placed at too high a temperature to prevent the tea from "aging".

The "aging" of tea leaves, in addition to the storage time, is also related to the temperature of the storage place. Experiments have shown that for every 10 times the temperature increases, the "aging" rate can increase by 4 times. Therefore, in the hot summer, especially in the south, the container of tea should be placed in a cool and dry place.

The container for placing tea leaves must be clean and odorless to prevent the smell of tea from deteriorating.

It is not possible to directly wrap tea leaves with mimeographed newspapers, because the ink will soon be adsorbed by the tea leaves and the tea will deteriorate; Do not use plastic bags (or boxes) such as packaged cakes, milk powder, biscuits, and preserved fruits to directly serve tea; Tea, even if it is packaged tea, should not be put in the kitchen, vegetable cabinet, wardrobe and camphor wood box, especially do not mix with soap, mothballs, etc., to prevent serious flavor and deterioration of tea.

Tea containers should be tightly sealed.

The better the container is airtight, the easier it is to maintain the quality of the tea leaves, and the longer the tea leaves in the container will be preserved. For containers that are prone to outgassing, seal them with 1-2 layers of clean paper on their lids or mouths to prevent moisture or odors from being inhaled from the inlet.
