Tea has an expiration date, and it is not allowed to be drunk after it expires. The shelf life of tea is related to the quality of the tea, and the shelf life of different tea leaves is different. For example, the aging quality of Yunnan Pu'er tea is better, and the shelf life can be as long as 10-20 years; Wuyi Rock Tea has a more fragrant aroma and a more mellow taste, so it has a long shelf life.

The shelf life of tea will have a lot to do with the type of tea, the shelf life of green tea and jasmine tea loved by Beijing people will be relatively short, generally 12 months or 18 months, but if the quality of the tea product itself is excellent, it is mainly to be dried and stored, and there is no problem with more than double the time.

Theoretically, tea leaves that have passed their expiration date should not be consumed again. Because the quality may have changed and no longer meet the standards and requirements of the product.

After all, the deterioration of tea is a continuous and gradual process, not a sudden.

The shelf life of green tea is shorter, usually about 1 year, and the word "fresh" is paid attention to when tasting, that is, the fresher it is, the better the taste. After the expiration date, although the tea leaves will not necessarily spoil, the flavor will inevitably go downhill.

White tea is the only two of the six major tea categories that meet the requirements of "the older the more fragrant".

Otherwise, it will deteriorate in two or three months, black tea, Pu'er, and rock tea can be put for a long time, but the taste will be differentGenerally speaking, the tea that has passed the shelf life, as long as there is no mold, can be drunk, but the experience will be different, especially green tea, fragrant Tieguanyin, etc., which are more likely to change the taste.

Usually, the shelf life of tea leaves in sealed packaging ranges from 12 months to 24 months, which will be indicated on the packaging bag of the tea. The shelf life of bulk tea is shorter, and when buying, try to choose the new tea of the year to buy.

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 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 drinking, 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 last 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.

Tea has a shelf life, and whether it can be drunk after expiration depends on the specific situation.

The expiration date of tea is divided into two situations, one is that although the tea has passed the expiration date, the quality is good, there is no sign of moisture and mildew, and the aroma is normal, the soup is bright and the taste is strong, then it can still be drunk. Second, the tea has passed the shelf life, and the tea has a musty smell, miscellaneous taste or peculiar smell, the dryness of the tea body is low, the soup color is turbid, and the aroma is unknown, then it can not continue to drink.

We must know that tea is a food and has a shelf life, according to GB7718 2011 "General Principles for the Labeling of Prepackaged Food of National Food Safety Standards", the shelf life must be marked on the outer packaging of tea.

The so-called "shelf life" can be understood as the best drinking period for tea under the premise of meeting the storage conditions indicated on the package. In order to ensure the best taste, it is of course the best and safest to drink within the expiration date.

Storage of tea:

Just put the tea leaves you bought from the market in a clean jar. However, in order to better keep the inside of the jar dry, you can put 1-2 sachets of silicone or preservative in the jar, which is more effective.

In addition, the tin cans or bamboo boxes containing tea should be placed in a cool place to avoid dampness and direct sunlight. If the canned tea is not drunk temporarily, it can be sealed with transparent adhesive tape to prevent humid air from penetrating. Although the canning method can slow down the aging and deterioration of tea, the effect is not as good as that of the altar storage method.

Tea generally has a shelf life and cannot be drunk after expiration. Drinking expired tea leaves can be a safety hazard and may have adverse effects on the body, expired tea leaves can be used as plant fertilizer or used to remove refrigerator odors.

When the tea leaves expire, not only will the composition change, but also the nutritional value will gradually be lost. After the tea leaves expire, they will gradually become wet, and there will be a moldy smell after the lump is finished, producing mold or bacteria, aflatoxins, etc. Therefore, be cautious when drinking expired tea.

Whether it is green tea or black tea, it has a certain shelf life.

If the expired tea leaves produce a peculiar smell, the damp mildew will not be drunk to drink. The shelf life of green tea and jasmine tea is relatively short, generally 12 or 18 months.

What else can tea do after it expires

Fill the ashtray with a layer of expired tea leaves, add a little water, and flick the ash inside, or extinguish the smoke in it, which is less likely to let the smoke and smell fly away.

Make pillows or sachets. If there are a lot of expired tea leaves, then you can consider using tea leaves as a filler for pillows. If there is not enough tea, you can also make a small sachet, hang incense everywhere, but whether it is a pillow or a small sachet, do not soak in water.

Expired tea can also absorb the odor in the environment, find a breathable cloth bag to fill the expired tea, or you can directly use an open container, and then put it in the refrigerator, which can absorb the odor in the refrigerator in a short time, and at the same time bring the fragrance of tea.
