Storage method
There are five reasons that affect the quality of tea: moisture, temperature, air, light and peculiar smell. Generally, low temperature and sealed vacuum are needed to ensure the color and fragrance of Tieguanyin in a short time. However, in actual preservation, it often happens that the color and fragrance of tea leaves are not as good as when brewing, because of the dryness after fermentation.
1, in modern storage methods, the effect is better:
Pumped nitrogen storage method
In a closed container, nitrogen is used instead of air, so that tea leaves can be preserved under oxygen-free conditions.
The specific method is as follows: first, put the dried tea leaves into a tea pot or aluminum foil bag with a crimping cover, then remove the air, fill in pure nitrogen, and finally seal.
Tea leaves are stored in nitrogen-filled containers, which can prevent the deterioration of tea contents due to Geng nitriding. At room temperature, the quality can be kept unchanged for one year. If it can be preserved at low temperature, the preservation effect will be better.
Low temperature storage method
In order to prevent tea from oxidative deterioration at low temperature. Specifically, dry tea leaves (the water content of tea leaves is below 5%) are put into a well-sealed container and stored at a low temperature below 3 degrees Celsius. For bulk tea storage, a special cold storage should be built to prevent moisture and heat, and the relative humidity of the air in the storage should be kept at about 50%.
2, drink a small amount of tea at home, often take:
Canning
It is best to use tin cans or tin cans with double lids. Wrap the tea leaves in paper, or put them directly in a jar. Shake tightly as far as possible, leaving no gap, reducing the air in the pot, which is conducive to maintaining the quality of tea.
After installation, cover the double cover and seal the cover with adhesive tape. The pot is covered with two layers of nylon bags, and the bag mouth is tightly tied. If this pot of tea is stored in the refrigerator or dryer, the effect will be better.
Simple methods such as nylon bag storage
Nylon bags should be stored in nontoxic, odorless and sealed nylon bags.
First, wrap the tea with clean white paper, then put it in the bag and squeeze it gently to exhaust the air in the bag and tighten the bag mouth. Then, take a nylon bag and cover it outside the bag filled with tea leaves. After exhausting, tie the bag tightly and store it in a dry and odorless iron pipe.
