Will vacuum packed tea expire? Tea leaves have a shelf life and will expire even when vacuum-packed. After the expiry date, the drinking value will be reduced, and there will be some changes. Therefore, it is better to buy the purchased tea before it expires.
Shelf life of different tea leaves
1. Green tea
The shelf life of green tea is usually about one year at room temperature. Since green tea is not fermented, the storage requirements are higher than other teas, and the shelf life is also the shortest. If stored properly, the shelf life can also be extended.
2. Black tea
Generally, the shelf life of black tea is relatively short, generally 1 year. The shelf life of black teas in secondary and autumn picking is 1-2 years, and the shelf life of Ceylon black tea is relatively long, which is more than two years. The shelf life of bulk black tea is generally 18 months, and the shelf life of general black tea in bags is 24 months. Black tea packed in cans or aluminum foil can be kept for about three years, and black tea packed in paper bags can be kept for about two years.
3. Black tea
It is generally believed that brick tea is stored for 10 to 15 years, Qianliang tea for 10 to 15 years, and loose tea for 5 to 10 years. It is economical and has a high drinking value. Fine tea made from high-end raw materials has a good taste for 1 to 2 years. .
Pu'er tea is divided into two kinds of raw tea and cooked tea. Generally speaking, the shelf life of raw tea is about 5 years. The cooked tea undergoes special fermentation and becomes more and more fragrant. The shelf life of tea is more than 15 years.
4. White tea
The general shelf life of tea is two years, because after the two-year shelf life, even if it is stored well, the aroma of the tea has disappeared, but the white tea is different. It is the same as raw Puer. The longer the storage year, the richer and richer the tea tastes. It is said that "one year of tea, three years of medicine, seven years of treasure", generally white tea of five or six years can be regarded as old white tea, ten or twenty years of old white tea is already very rare.
The longer the storage time of white tea, the higher its medicinal value, so the old white tea is extremely collectible. White tea is said to be as old as possible. Of course, it is also necessary to keep it well. White tea is generally sealed and stored, otherwise it will lose moisture or moisture. Only one year of tea, three years of medicine, and seven years of treasure are preserved.
5. Yellow tea
Yellow tea is a type of fermented tea. The production of yellow tea is similar to that of green tea. The difference is that there is one more boring process. Therefore, the retention period of yellow tea and green tea is only about one year.
6. Oolong tea (green tea)
Unlike Pu'er tea, the longer the storage period, the more mellow the taste. Under normal circumstances, oolong tea is refrigerated for 18 months. If it is roasted oolong tea, it can be pushed back for six months, up to 24 months. Roasted oolong tea does not need to be kept fresh. In a cool and ventilated place.
