Small knowledge of tea shelf life. We often entertain guests with tea drinks, but there are many kinds of tea, and different teas have different shelf life. I collected and sorted out the relevant information about the knowledge of tea shelf life for everyone. Let's have a look.
Knowledge of tea shelf life 1 shelf life of different kinds of tea
Shelf life of green tea
Green tea belongs to unfermented tea. The average shelf life of green tea is about 18 months. If it is kept for too long, it will begin to fade. But under certain conditions, the shelf life can still be extended to more than three years. You should stay away from five enemies: light, air, heat, moisture and smell.
Shelf life of black tea
Black tea is completely fermented and has a longer shelf life than green tea. Generally speaking, the shelf life of bulk black tea is about 18 months, while the shelf life of bagged black tea in Chaze is 24 months. Black tea pots or aluminum foil bags can be kept for about 3 years, and paper bags can be kept for 2 years.
Shelf life of oolong tea
Oolong tea belongs to semi-fermented tea, and its shelf life is about 2 years. But for loose-leaf oolong tea, the shelf life will be shorter. In addition, the shelf life of oolong tea depends on the fermentation degree and storage method, and it is more necessary to choose a sealed container and put it in a dry, dark, closed and odorless place.
Shelf life of white tea
White tea is a special treasure. People say that the longer it is stored, the higher its medicinal value will be. If stored properly, the shelf life of bagged tea is usually 2 years. After this period, even if the best way is maintained, the aroma will gradually disappear. When it comes to white tea, it's completely different. Just like raw Pu 'er tea, the longer it is stored, the richer it becomes. Also known as "one year tea, three years medicine, seven years treasure" (one year tea, three years medicine, seven years treasure). Most of the aged white tea we buy from the market or tea shop is 5-6 years old. If you have a tea for more than 10 or 20 years, you have a very valuable tea.
Shelf life of black tea
Shelf life of black tea (black tea) Pu 'er is a subset of black tea. According to the way of making tea, Pu 'er tea has two kinds: raw tea and cooked tea. Is its maximum storage limit 5 years or 50 years? It's hard to answer. There is no definite time limit for the preservation of Pu 'er tea. Proper storage of Pu 'er tea will improve the quality and produce delicious fragrance.
Knowledge of tea shelf life 2 Which kind of tea has the longest shelf life?
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 are a local tyrant and have a refrigerator dedicated to storing green tea, the shelf life can be extended to about 18 months.
black tea
Black tea is a kind of fully fermented tea, which has a long shelf life and can be preserved for more than 2 years. But generally speaking, even if it is properly preserved, it will go bad after more than 2 years, so try not to wait until 2 years later.
oolong
Oolong tea is semi-fermented Generally speaking, if it is kept in the refrigerator, it can be kept for about 18 months. Baked tea, like Wuyi Rock Tea, can be drunk even after 2 years.
white tea
"1 year-old tea, 3-year-old medicine, 7-year-old treasure" white tea has the characteristics of more aging and more fragrant. The longer it is stored, the more its value and taste will increase. Of course, this means that even the best tea leaves, if stored improperly, will also become slag.
Dark tea
Black tea also has the characteristics of fragrance as it ages, and can be stored for a long time in a clean, moisture-proof and odor-free environment.
However, after post-fermentation, it has no unlimited potential like raw tea and white tea. Generally speaking, the taste of loose tea has reached the best level within 3 or 5 years. If the tea leaves are pressed, it will be almost from 10 to 15, and there is not much room for appreciation.
Yellow tea
As the lowest-key non-existent yellow tea,
In the production process, there is only one more dull yellow than green tea.
Its shelf life has not been greatly improved because of stuffy yellow.
About 1 year, that's about it.
Pu'er tea
As the most popular Pu 'er tea in recent years,
The characteristics of Chen Nianxiang were "fried" by collectors.
When the tea leaves are ripe, they are generally over 15 years old.
Raw tea, the more fragrant, the more valuable.
