Storage method:

Tea has a shelf life, but it is related to the variety of tea, and the shelf life of different teas is different. As long as it is stored properly, it will not deteriorate and even improve the quality of tea.

Fresh-keeping skills:

1. If possible, you can pump the air out of the tea in the tin, and then weld and seal it, so that the tea can be stored for two or three years. If the conditions are not enough, you can put it in a thermos bottle, because the water bottle is isolated from the outside air and the tea leaves are put in the bottle. Cover the plug tightly, seal it with white wax, and then stick it with adhesive tape. It is simple and convenient to keep it at home.

2, ordinary bottles, cans, etc. To preserve tea, it is best to use a pot with double covers inside and outside or a pot with a big mouth and a big belly, which can reduce the air contact in the container. The container cover should be closely combined with the container body to prevent moisture from entering.

3. Tea packaging materials should be tasteless, tea containers and usage methods should be as airtight as possible, with good moisture-proof performance to reduce contact with air. Store in a dry, clean and odorless place.

Store in the cold room or refrigerator, and pay attention to seal the tea leaves before putting them in.

5. Use quicklime or advanced desiccant, such as silica gel, to absorb the moisture in tea, which has a good fresh-keeping effect.

6. Based on the principle that the air in the pot is thin and the tea leaves in the pot are isolated from the outside world after sealing, the tea leaves can be dried until the water content is about 2%, immediately put into the pot, and then sealed, or stored at room temperature for one or two years.
