Bought a good tea, a moment is not so fast to drink, or want to share with friends, then how to store it? The main factors that cause tea deterioration are: light, temperature, tea moisture content, atmospheric humidity, oxygen, microorganisms, odor contamination. So, if you want to store your tea well, you must pay attention to these problems. Here is a look at the common methods of tea storage with the editor.

"Tea storage methods"

1, plastic bags, aluminum foil bags storage method

The best choice of sealing and for the plastic bags used for food, the material is thicker, higher density is better, do not use the taste or re-produced plastic bags. Filled with tea after the bag of air should be squeezed out as much as possible, if you can use a second plastic bag reverse set on the better to transparent plastic bags after the tea should not be exposed to sunlight. Aluminum foil bag tea principle and plastic bags are similar. In addition, will buy back the tea bag packaging, sealed device in the refrigerator, and then brewed in batches to reduce the opportunity to open the tea leaves and air contact, to delay the production of quality deterioration.

2, metal cans storage method

Can choose to use iron cans, stainless steel cans or dense texture of the tin cans, if it is a newly purchased cans, or the original storage of other items to stay in the flavor of the cans, you can use a little tea in the cans, cover the lid, up and down, left and right, shake the walls of the cans lightly rubbed and discarded, in order to remove the odor. Commercially available two-layer lid stainless steel tea cans, simple and practical, such as with a clean and odorless plastic bags filled with tea, and then placed in the can with a lid to tape to seal the lid mouth is better.

Metal cans with tea should be placed in a cool place, do not put in direct sunlight, odor, humidity, heat sources, so that the tin cans are not easy to rust, but also to slow down the aging of tea, deterioration of the speed. Another tin cans dense material, moisture, oxidation, blocking light, anti-odor has a very good effect.

3, low-temperature storage method

The tea storage environment to maintain below 5 ℃, that is, the use of cold storage or freezer to save tea, the use of this method should pay attention to:

Storage period of six months or less, the refrigeration temperature to maintain the 0 ℃ -5 ℃ the most economically effective; storage period of more than half a year, in order to freezing (-10 ℃ -18 ℃) is better. Tea storage to special refrigerated (freezer) library is best, such as must be with other food *** refrigerated (frozen), the tea should be properly packaged, completely sealed to avoid adsorption of foreign flavors. The air circulation inside the refrigerator (freezer) is good in order to achieve the cooling effect. When purchasing a large quantity of tea at one time, it should be packed in small packets (cans) and put into the refrigerator (freezer), and then take out the required amount of tea each time; it is not advisable to freeze and thaw the same packet of tea repeatedly. When you take out the tea from the refrigerated (frozen) warehouse, you should let the temperature of the tea in the tea canister rise to a temperature similar to room temperature before you take out the tea, otherwise, if you open the tea canister suddenly, the tea will be easy to condense and increase the water content, which will accelerate the deterioration of the tea that has not been brewed.

4, ceramic altar storage method

Select dry, odorless, airtight ceramic altar, with kraft paper to the tea package, placed in the altar around the middle of the embedded lime bag, the top and then put the tea bag, filled altar, with cotton bags covered tightly. Lime every 1-2 months replacement. This method uses lime hygroscopic properties, so that the tea is not damp, the effect is better, can maintain the quality of tea for a longer period of time, especially Longjing flag gun generous and some other valuable tea, the use of this method is particularly appropriate.

5, tea long-term storage and reprocessing methods

Tea moisture content control in 3% -5% to be preserved for a long time, roasting and drying degree of tea storage period has a fairly important relationship; in general, the roasting is heavier, lower moisture content can be stored for a longer period of time.

When the optimal storage period of tea leaves expires, it should be taken out and roasted again. Can wash the rice cooker to no smell, wipe dry after pouring tea on a porcelain plate or aluminum foil into the rice cooker, open the concern to the "heat preservation" position, the lid half-covered, turn it over at the right time, about half a day time, the tea from the old taste to the clear ripe incense, to the food thumb pinch that is broken for the appropriate, cool down and cool down, and then can be packaged for storage.

Some people use microwave oven drying, baking tea, only its heating time is short, and the door needs to be closed, the fire is not easy to control, often leading to the surface of the tea charcoal or stale flavor can not escape the shortcomings of the technology is still to be overcome. The most secure method is to collect the tea leaves and ask the familiar tea master or tea farmers to do the roasting on behalf of the tea master.

Summary:

Tea is actually one of the food, in addition to fermented tea Pu'er, other tea has a shelf life. According to the different varieties of tea, growing conditions, etc., the shelf life is not the same. If not properly preserved, such as moisture caused by excessive moisture content, tea may expire early.

And determine whether the tea is expired, can be identified by the following methods: to see whether the moldy or stale taste; green tea is not red, dark soup color; tea flavor concentration, freshness and so on. In addition, you can look at the shelf life on the packaging, if it is bulk tea, it is best not to drink more than 18 months.

The preservation of tea in today's world is still a major problem, there is no one way to make tea fresh for a long time, can only try to prolong the freshness of tea and their own. Even if the best way to save, due to the differences in the production process of tea, so that the freshness of different teas are different, green tea, white tea, yellow tea due to unfermented or light fermentation, the most difficult to keep, generally new tea listed three months after the beginning of the flavor.

Green tea (oolong tea) is semi-fermented can be preserved for about half a year, can still have the fresh flavor of tea.

Black tea is fully fermented and can be kept longer.

Black tea is post-fermented tea, due to the special production process. Make the black tea can save the more the quality of the better, known as "tea antiques" and "black gold" known.

Tea and absorb moisture and strong flavor, it is easy to adsorb moisture in the air and odor, if the storage method is a little improper, will lose flavor in a short period of time, and the more light fermentation and high fragrance of the precious tea, the more difficult to save. Usually tea in storage for some time, aroma, color, taste, color will change, the original new tea flavor disappears, the old taste gradually revealed.
