The shelf life of different tea leaves is different, so what is the shelf life of different teas?

In addition to fermented tea, the general shelf life of other teas ranges from 12 months to 24 months, oolong tea can generally be stored for 2 to 3 years, Hunan black tea, Hubei's green brick tea, Yunnan's Pu'er tea can be stored for about 10 years, and green tea is generally preserved for 8 months to 9 months.

Generally speaking, the shelf life of raw tea is about 5 years, and the more ripe tea is aged after special fermentation, the more fragrant it is, and the shelf life of tea is more than 15 years. Generally, the shelf life of black tea and green tea is relatively short, generally 1 year.

Generally, the shelf life of sealed packaged tea is generally between 12 months and 14 months, if it is green tea, if you want to be fresh and delicious, it is generally about half a year, oolong tea is generally 2 to 3 years, like black tea, if the quality is particularly good, then its shelf life can be as long as several decades.

Generally, the shelf life of tea is related to the variety of tea, and the shelf life of different teas is not the same as Xiangyan:

1. The shelf life of sealed tea is 12 months to 24 months, which will be indicated on the packaging bag of tea.

2. The shelf life of bulk tea is shorter, so when purchasing, try to choose the new tea of the year.

3. Fresh tea, such as green tea, has a shelf life of about one year at room temperature. However, the main factors affecting the quality of tea are temperature, light and humidity. If stored properly, these factors are reduced or eliminated, and the tea leaves can last for a long time.

To determine whether the tea is expired, there are mainly the following aspects:

1. See if it is moldy or stale; Whether the green tea turns red, and the soup color turns brown and dark;

2. The concentration, astringency and freshness of the taste decreased;

3. Look at the shelf life on its packaging, and if it is a bulk tea, it is best not to drink it for more than 18 months.

The storage time of various types of tea is as follows:

1. Green tea. Green tea has the shortest shelf life, generally speaking, the shelf life at room temperature is about 1 year. Of course, if you have a refrigerator dedicated to storing green tea, the shelf life can be extended to about 18 months.

Green tea is unfermented tea, and the storage requirements are relatively high, and new tea is generally left for half a month or a month to drink after drinking. Green tea has the shortest shelf life compared to other teas, and because it has not been fermented, it requires higher preservation requirements. If it is not stored properly, it may start to turn yellow and change its flavor after a few months.

2. Black tea. Black tea is a fully fermented tea with a relatively long shelf life and can be stored for more than 2 years. However, even if it is stored properly, it will change its flavor after more than 2 years, so try not to wait until 2 years later to drink it.

Generally speaking, black tea is best tasted in the second year. Because the aroma of black tea that year is better, but the taste is not so mellow; If you drink it after one year, the aroma will be more elegant, and the tea soup will be softer and smoother. If you store it for more than 2 years, it may spoil, so it is recommended to buy it in moderation and do not wait until it has spoiled.

3. Oolong tea.

Oolong tea is a semi-fermented tea, and generally speaking, it will only take about 18 months if it is refrigerated in the refrigerator. And those that have been baked, like Wuyi rock tea, can still be drunk even if they are left for 2 years.

Because the production process requires a roasting process, the new tea should be left for at least 2 months after it is made, and then drink it after the fire subsides, so that the taste is better, and there is no need to worry about getting hot after drinking. However, the shelf life of the fragrant Tieguanyin, which has not been baked or has a slight degree of baking, is not as long as expected.

4. White tea. "1 year tea, 3 years of medicine, 7 years of treasure" white tea has the characteristics of the older the more fragrant, white tea is drunk in the year, it is cool, so it is best to put it in a certain year and then drink, the taste is mellow. And the longer the storage year, the value and taste will not decrease but rise, of course, this means that if it is stored properly, if it is not stored properly, no matter how good the tea is, it will become slag.

5. Black tea. Big black tea also has the characteristics of getting older and more fragrant, and can be stored for a long time in a clean, moisture-proof, and odor-free environment. However, due to the post-fermentation, there is no unlimited potential of raw pu and white tea, generally speaking, the taste of loose tea has reached the best level, and 10 to 15 years of pressed tea is not about the same, and there is not so much room for appreciation.

6. Yellow tea. As the most low-key and non-existent yellow tea, the production process is just more dull yellow than green tea, and its shelf life has not grown much because of the dull yellow. In about 1 year, it's about the same.

7. Pu'er tea.

Pu'er tea is classified as dark tea in the classification of the six major tea categories, and it has the same characteristics as black tea, which is more fragrant the older it gets. However, Pu-erh tea is slightly different from dark tea, and Pu-erh tea is divided into raw tea and cooked tea.

As the most popular Pu'er tea in recent years, the older it is, the more fragrant it is, and it has been "fried" by the majority of collectors. Generally speaking, ripe tea is more than 15 years old, and raw tea is more and more valuable as it ages.

The shelf life of different tea leaves is different. The storage time of various tea leaves is determined according to the variety of tea and how fresh it is. Fresh green tea will be stored for a shorter period of time, and the taste and color will change after a long period of storage, that is, it will become an aged tea.

Black tea is a fermented or semi-fermented tea, so it will be stored for a longer time, such as Pu'er tea, which can even be stored for decades or even hundreds of years.

1. The shelf life of tea is affected by temperature, light, humidity, etc., and the shelf life of tea in sealed packaging is usually 12 months to 24 months.

2. The shelf life of bulk tea is shorter, and bulk tea is easy to absorb moisture, taste, and is also more prone to deterioration, so it is recommended not to exceed 18 months. The shelf life of different tea leaves is different: the shelf life of black tea is relatively short, the shelf life of bulk black tea is generally 18 months, and the shelf life of bagged black tea is 24 months.

Green tea and yellow tea for a year and a half.

Drink fragrant oolong for half a year.

Black tea is stored for two or three years.

Pu'er white tea is forever alive.
