How to save West Lake Longjing
Lime storage
The traditional household storage method generally uses the lime cylinder drying method and has a good effect.
Select containers with appropriate volumes and good sealing properties such as iron boxes, glass bottles, rice cylinders, and ceramic jars. The size depends on the number of tea leaves to be packed. It requires drying, cleaning, tasteless, and rust-free. First place the lime bag in the center of the container, then wrap the dry tea in a clean tissue paper. Care should be taken not to use old newspapers to prevent the tea from absorbing ink. About half a kilogram of each package, tied with a string, layer by layer into the tank around the seal can be.
Carbon storage
The specific method is similar to the lime storage method. The difference is that charcoal is used instead of quicklime as a desiccant, which means that 1kg of charcoal is put into a cloth bag and replaced every other month or two.
If charcoal absorbs moisture, charcoal must be red-hot and then put into a cloth bag after cooling. Each bag weighs about 1 kilogram; every two months, the charcoal should be removed and dried.
Plastic bag, aluminum foil bag storage method
It is better to use a plastic bag that is sealed and used for food packaging. The material is thick and has a high density. Do not use plastic bags with flavor or remanufacturing. The air in the bag after the tea is packed should be squeezed out as much as possible. If it is possible to use the second plastic bag to reversely cover it, it is better. After the tea is packed in a transparent plastic bag, it should not be exposed to sunlight. The principle of aluminum foil bagged tea is similar to that of plastic bags. In addition, the bought tea is packaged in bags, sealed in a refrigerator, and then brewed in batches to reduce the chance of the tea coming into contact with the air after opening and delaying the deterioration of quality.
Metal tank storage
Tin cans, stainless steel cans, or densely tinned cans can be used. If it is a newly purchased jar, or a jar that has previously been stored with other items, it can be placed in a jar with a little tea, covered with a lid, and shaken up and down. Gently brush the wall and discard it, or bake the can with a fire to remove the odor. There are two types of stainless steel tea pots sold on the market, which is simple and practical. If it can be combined with clean and odorless plastic bags of tea, the lid can be placed inside the cans and the lids can be sealed with tape. Metal cans with tea should be kept in a cool place. Do not place them in direct sunlight, smelly, humid, or heat-producing areas. In this case, iron cans are not prone to rust, and they can slow down the aging and deterioration of tea. Another dense tin material, moisture, oxidation, light block, anti-odor have a good effect.
Cryogenic storage
Keep the tea storage environment below 5°C, that is, use cold storage or freezer to preserve the tea. If you store for the family, you can use the refrigerator. This method should pay attention to:
(1) The storage period is less than six months, and the coldest storage temperature is 0~5°C, which is the most economical and effective; the storage period is more than six months, and the freezing (-10°C to -18°C) is preferred.
(2) It is best to store tea with a special cold storage (freezer). If it is necessary to refrigerate (freeze) with other foods, the tea should be properly packed and completely sealed to avoid odor absorption.
(3) The air circulation in the refrigerated (freezing) storehouse is good to achieve a cooling effect.
(4) When purchasing a large amount of tea at a time, it should be packaged in small packets (cans) first, and then placed in a refrigerated (frozen) library. Each time the required amount of brewing is taken out, it is not appropriate to repeatedly freeze and thaw the same tea.
(5) When removing the tea leaves from the cold (freezer) storage, the temperature of the tea leaves in the tea pot should be brought up to the same temperature as the room temperature before the tea leaves can be taken out. Otherwise, the tea pot can be opened and the tea leaves can easily condense moisture and increase the moisture content. Make unbleached tea accelerate deterioration.
