Nowadays, there are many tea leaves available for everyone to choose from.
From the general direction, there are black tea, green tea, white tea, black tea, green tea and yellow tea.
Further subdivided, it can also be divided into small black tea, red crushed tea, Wuyi rock tea, Tieguanyin, white peony, white silver needle, West Lake Longjing, Biluochun...
It can really be said that a hundred flowers bloom, a hundred schools of thought contend, and people are overwhelmed.
There are so many types of tea, if you want to choose a tea that suits you, you need to take the time to understand, to study, to explore, to analyze, so as not to choose the wrong tea.
Careful tea friends have also found a rule in the tea circle that is tacitly accepted by everyone, and if you want to drink old tea, you must choose white tea and black tea, while black tea and green tea are not related to old tea.
At this time, new tea friends will ask why white tea can be stored in old age, but black tea and green tea cannot?
The answer to this question has to be said slowly.
Why white tea can be stored for a long time, mainly because of its simple process.
The process of white tea is mainly withered and dried.
Withering, in simple terms, is dehydration.
The harvested tea green is spread out in time and thinly dried on a water sieve 70 cm above the ground, so that it can be naturally dehydrated.
When the water content of the withered white tea is about 15%-20%, it is time to dry this step.
Using the method of slow drying, the water content of white tea is controlled below 8.5%.
Explaining the main process of white tea, it can be found that its production steps are relatively simple, there is no greening or kneading, and the nutrients in the tea leaves are more completely retained.
During the storage process, the nutrients in white tea will react with trace oxygen molecules to form new substances.
For example, as the aging year increases, the amount of caffeine and tea polyphenols in tea will gradually decrease.
Flavonoids will gradually become richer as the storage time increases.
According to various performances, white tea has the reputation of one year tea, three years of medicine, and seven years of treasure, with the characteristics of the more aged and fragrant.

Black tea and green tea are not recommended to be stored as old tea, which is the consensus in the tea circle.
Once, a tea guest read an article about green tea not being stored for a long time, leaving that appalling story in the comments section.
He said, who said that green tea can not be stored for a long time, I once drank green tea that has been stored under the old mansion in Shanxi for 30 years, and it tastes very good.
You just haven't drunk it, you don't have the resources in your hands, you won't be able to eat grapes and say grapes are sour.
belch......
What a wrong!
To be honest, regardless of whether the year in which this tea was stored is real or not, how it sounds terrible to dig out from under the old house.
Think about how many microorganisms there will be under the ground, whether they are good or bad, it depends on professional instrument testing.
But it is undeniable that there will certainly be a certain degree of harm, and it is not known how many are small.
In addition, the groundwater is full and the tea leaves are stored in the ground, which is simply self-seeking.
Tea is not daughter red, the existence of the underground time does not have to be too long, into inferior tea is inevitable.
Then combined with the process of green tea, its main process is to kill the green.
After experiencing the green tea leaves, the inner substance has long lost the ability to transform, stored for too long, it will not help at all.
In addition, after green tea is killed, tea polyphenols are more retained, and such substances are easily oxidized, and once they are oxidized, the flavor will be greatly reduced.
Therefore, many tea lovers who love green tea will buy a Xiaoice box for unopened tea, hoping to retain its flavor for a longer time.
Most green tea on the market is written on the outer packaging, and the shelf life is about 12-18 months.
Black tea is a tea with a high degree of fermentation, and a large number of substances have been transformed in the process of production, and long-term storage has no value.
When black tea and green tea are in hand, it is safest to drink them into the stomach as soon as possible.
Storing it as old tea is completely seedling-boosting.

Although white tea can be stored for a long time, not all teas have been stored for many years as high-quality old white tea.
Perhaps, such words may sound incomprehensible to some people.
In their view, as long as the vintage is enough, the quality of white tea is outstanding, it is outstanding.
In fact, this is not the case.
White tea wants to be stored as much as possible, the contents of tea need to be abundant, and the storage method needs to be in place, otherwise it will take a long time to be useless.
The reason why white tea can be aged for a long time is because its process is simple, a large amount of nutrients are retained, and in the process of storage, nutrients and trace oxygen molecules will react.
It can be seen that nutrients and trace oxygen molecules are the driving force for the aging of white tea.
If there is a problem with the quality of a tea, and the nutrients are scarce and shallow, so is it possible to store as much as possible?
The answer is, no.
Again, if a white tea is stored in vacuum packaging and there are no trace oxygen molecules inside, can it become more and more fragrant?
The answer, again, is no.
It can be seen that if you want to have high-quality old white tea, its quality is very critical.
Choose tea, it is recommended to choose alpine white tea.
In the high mountains, in terms of temperature, light, moisture, air quality and soil fertility, they are extremely suitable for tea plants to accumulate nutrients.
High-quality tea green, tea farmers will not be taken lightly when making it, and will use the process in place to make it and retain its nutrients intact.
For tea storage, it is recommended to use three layers of packaging.
The so-called three-layered one refers to aluminum bags, food-grade plastic bags and corrugated boxes with five thicknesses.
The finished white tea is stored in a sealed, moisture-proof, light-proof, odor-free environment to avoid interference with its quality by the external environment.
Although the three-layer packaging has good sealing performance, there is no need to worry about no oxygen molecules in it that can react with the tea leaves.
When packaging, the excess air is squeezed out manually, and the tea leaves are interlaced with the tea leaves, leaving a little air.
The oxygen molecules contained in the air are enough to transform the white tea substance, so that it has the characteristics of aging and fragrance.

Old tea has always attracted much attention.
Because it has gone through a long time, there is a charm that time has given it.
Time is priceless and never goes back.
Over the years, white tea will become mature, will become introverted, will become stable, and will become completely different from the new white tea.
Presumably, tea lovers like old tea, and what they love most is its charm.
However, not all teas are suitable for storing as old teas, just like the life path that everyone wants to take is different.
Green tea, black tea, etc. are not recommended for long-term storage.
Like old tea, please go to white tea, black tea to find, and when purchasing, pay attention to the quality of tea and storage methods.
Otherwise, spending a lot of money to buy tea home, the quality of the tea is not satisfactory.
That's a big loss!
