How many years is the shelf life of tea? Can you still drink tea that has been left out for three ye

Generally, the shelf life is about one to two years, and if you leave it for a long time, try not to drink it, because these tea leaves have gone bad and the taste is gone.

The shelf life of different tea leaves is different. If it is a dark tea, then the shelf life is very long, and the longer it is stored, the better it tastes.

The storage environment and method of tea are the most important!

1. Generally speaking, the shelf life of green tea and yellow tea is short, and it is only about a year to make it early at room temperature. The shelf life of black tea is also not long, the bagged one is 1-2 years, and the canned one can be stored for three years. The shelf life of green tea is not very long, generally around 18 months.

2. In the case of proper preservation, Lu Heng, white tea can be aged as much as possible, known as one year of tea, three years of medicine, seven years of treasure. When storing white tea, it is generally necessary to seal and store it to avoid moisture. Whereas, black tea can also become more fragrant as it ages, without an expiration date, but it does not need to be stored completely sealed.

3. Once the tea has passed the expiration date, it may deteriorate, affecting the taste, and it is not recommended to drink it again. No matter what kind of tea, if it is not stored properly and there is mildew, it can not be drunk again, otherwise the damage to the wide body of the body is relatively large.

1.Tea has a shelf life green tea - unfermented, the shortest shelf life is about 1 year Generally speaking, the shelf life at room temperature is about 1 year, if it is not stored properly, it may start to wither yellow in 9 months, and some taste.

2.If you have a space dedicated to storing green tea, the shelf life can be extended to about 18 months.

3.Black tea - fully fermented tea, the shelf life is about 2 yearsGenerally speaking, even if it is stored properly, there will be a phenomenon of taste change after more than 2 years, so try not to wait until 2 years later to drink, which will also affect the taste.

4.Oolong tea - semi-fermented tea, about 2 years or 18 months has not been roasted or the degree of roasting is very light, the shelf life is not as long as imagined, generally speaking, it is about 18 months if it is refrigerated in the refrigerator.

5.And those that have been roasted, like Wuyi rock tea, can still be drunk even if they are left for 2 years.

6.White tea - 1 year tea, 3 years of medicine, 7 years Bao white tea has the characteristics of aging and fragrant, and the longer the storage year is when stored properly, the higher the value and taste.

7.Black tea - loose tea for 3-5 years, pressed tea for 10-15 years in a clean, moisture-proof, odor-free environment, can be stored for a long time.

8.Generally speaking, loose tea is 3-5 years old, and the taste has reached the best level, and pressed tea for 10-15 years is about the same.

9.Yellow tea - the shelf life is 1 year, and the production process is more sullen than green tea (refers to the unique process of piling up the tea leaves while they are hot after finishing or rolling or initial roasting, so that the tea blank gradually turns yellow under the action of damp heat.

10.Its shelf life is about 1 year, and it has not grown because of the dull yellow.

11.Pu'er tea - ripe tea for 15 years, the older raw tea is, the more valuable ripe tea is, generally more than 15 years.

At the same time, it depends on the degree of tea fermentation, Pu'er tea is a fully fermented tea, of course, the longer it is put the better, Tieguanyin pure powder is a semi-fermented tea, so the shelf life can not be stored like Pu'er tea, if you want to put it for a long time before you drink it, it is recommended that you put the sealed tea leaves in the refrigerator freezer. This allows it to be stored for a longer period of time. It also does not affect the taste.

The shelf life of tea is related to the variety of tea, and the shelf life of different tea leaves is also different. Like Pu'er tea, black tea, etc., are fully fermented products, and the shelf life can reach 10 to 20 years. Therefore, the state does not set a shelf life for it.

Similar teas include Wuyi rock tea, Guangxi Liubao tea, etc., as long as this kind of tea is stored properly, not only will not deteriorate, but can improve the quality of tea.

In general, it is better to be fresh. Like green tea, the shelf life is generally about one year at room temperature. However, the main factors that affect the quality of tea are temperature, light, and humidity.

If stored properly, these factors are reduced or eliminated, and the tea leaves can be shelved for a long time. To judge whether the tea is expired, there are mainly the following aspects: to see whether it is moldy or old; Whether the green tea turns red, and the soup color turns brown and dark; The concentration, astringency and freshness of the taste decrease, in addition to the shelf life on its packaging, and if it is a loose tea, it is best not to drink it for more than 18 months.

1. The shelf life of green tea should take into account the material of the packaging and the ambient temperature. Since green tea is easy to absorb moisture, the quality will change when the moisture reaches more than 60%, and green tea stored for a long time will lose the unique flavor of fresh tea even if it is not opened. Generally speaking, the fragrance of fresh tea leaves can be maintained for 3 months after picking and making tea leaves, so it is best to drink them while they are fresh.

Green tea can be stored for about 1 year at the right temperature, and it is best to pour it into an airtight container after opening and drink it within 1 month.

3. As long as Pu'er tea is placed in a cool, dry, ventilated and odorless environment, it can be stored for a long time, and the older it is, the more fragrant it becomes.

Pu'er tea is divided into raw Pu and ripe Pu, raw Pu refers to the storage and dry, ventilated place, so that the tea leaves are naturally transformed and fermented, at least five years to store for more than five years, in order to achieve the effect of Zaoyu aged tea fermentation; The aroma reaches its best when it is left for 20 to 30 years, and some can even be stored for 50 years; Ripe Pu is to accelerate the fermentation of Pu'er tea by artificial methods, and the aging rate is faster than that of raw Pu, which can be left for 3 to 5 years, but the taste is not as good as that of naturally fermented raw Pu.

4. The shelf life of oolong tea is not as long as that of Pu'er tea, usually after oolong tea is processed and made, it must be drunk within 1 to 2 years after being put into the package.

In a drier environment, you can place a small glass of water next to the tea to increase the humidity in the air slightly. The humidity should be artificially controlled, the average annual humidity should not be higher than 75%, due to the warm marine climate along the coast, the humidity will be higher than 75% in the rainy season, so more attention should be paid to open the windows in time to ventilate and dissipate moisture.
