Keep things in the refrigerator if you can't finish them. Everyone understands this. However, not everything is suitable for refrigerators. For example, some tea leaves, if you don't pay attention, the good tea is gone.
For those who like to drink tea, the storage of tea leaves is a big problem. Tea has moisture absorption and strong adsorption, it is easy to absorb moisture and peculiar smell in the air (key point: tea can remove peculiar smell). Many people waste hard-won good tea because the tea is damp or deteriorated because it cannot store it. Light, temperature, moisture content of tea, air humidity, microorganisms, and odor pollution, any of them may cause the deterioration of tea.
How to store the tea? Different teas have different storage, but the total is 11 words: sealed, protected from light, pressure, moisture, and odor.
Which teas need to be put in the refrigerator?
Green tea, fragrance oolong tea, yellow tea
Green tea is best stored in the refrigerator, especially tea with high aroma such as Longjing tea. This is because it is easily decomposed under light and heat conditions, turning green and brown. If the storage time is short and you need to drink it at any time, you can put the green tea in the refrigerator and adjust the temperature to about 5 degrees Celsius; if it is unopened tea, you should put it in the freezer if you want to keep it for more than one year.
One prerequisite is that you can't put other things with peculiar smells and store them in the cold. The tea should be dry and sealed in a food-grade packaging bag with good airtightness. The tea can absorb the peculiar smell best. It is best to refrigerate in small packages, and then take out a small bag after drinking to avoid repeated storage and retrieval from the refrigerator.
The fragrant Tieguanyin is put in the refrigerator to reduce the oxidation rate of various components in tea and maintain the original color and fragrance. In the same way, the sealed tea can be put in the refrigerator, otherwise it will be discarded.
Yellow tea can also be stored in the refrigerator. As for dark tea, black tea, scented tea, white tea, and other oolong teas, they can’t be stored in the refrigerator, as long as they are placed in a relatively ventilated, dry and cool place, but they should not be kept with odorous things.
Oolong tea and black tea have a relatively low content of polyphenols, slow aging and deterioration, and are easy to store; while scented tea has a strong floral fragrance, and storage under low temperature conditions will inhibit its aroma and reduce the freshness and concentration of the aroma. Pu'er tea is best stored at room temperature in a ventilated and dry place. Because Pu'er tea is a fermented tea, it contains beneficial bacteria. The taste of Pu'er and the more fragrant as it ages are thanks to these enzymes. Enzymes need to work in a ventilated, cool, and dry environment, which is not enough if placed in the refrigerator, and they are prone to mildew when they are wet.
What are the conventional tea storage containers?
Generally speaking, tin cans, altars, and colored glass bottles are the best containers for storing tea.
Secondly, iron cans, wooden boxes, bamboo boxes, etc. should be used, and bamboo boxes should not be used in the dry north.
Plastic bags and cartons are the last.
Many tea houses choose a crock made of purple sand, wrap the tea leaves with film paper, and then seal them for preservation.
Now tea leaves are basically vacuum-packed in small bags, so you can choose the container you like. Here we take loose tea as an example to discuss.
What kind of tea should be put in what pot?
It is best to put it in a tin can, seal it and put it in the refrigerator.
Oolong tea is a semi-fermented tea, so it does not need to be stored as carefully as unfermented tea. It is easier to store. It is better to use tin cans for tea. If you don’t have one, you can also use iron cans, porcelain cans, or tinplate tea cans with double lids. Remember to seal them.
Dry black tea has a low water content and is easy to be damp or smelly. During storage, try to avoid mixed storage of different kinds of tea. Generally, it can be placed in a closed dry container, protected from light and high temperature, and can be packed in tin foil or tin foil. Tea is better. If possible, it is better to use purple sand cans or tin cans. It is difficult to guarantee that glass cans will not be exposed to sunlight. If you are using a plastic bag, remove the air from the bag before putting it in to better retain the tea aroma.
Keeping it ventilated and dry is the most important thing to pay attention to when storing black tea. It is best to use kraft paper, leather paper and other packaging materials with good permeability (a plastic bag should not be used) to seal it for storage. If you accidentally cause the tea to become moldy and white due to damp due to excessive humidity or too long, you should take it out in time to a ventilated and dry place, you can also dehumidify (just turn on the air conditioner), or dry it in the sun The mold hair that grows after days will naturally disappear, but if it is black mold, green mold, and gray mold, it is bad tea.
All in all, the container for storing tea should be dry, clean and free of odor. Can not be placed in humid, high temperature, unclean or exposed places. There should be no strong odor items such as camphor, medicines, cosmetics, cigarettes, and detergents. Put the refrigerator in the refrigerator, but also note that different types of tea cannot be mixed and stored.
