To properly store Sheng tea, it's essential to use packaging materials that are odorless and have excellent moisture resistance. The containers should be as airtight as possible to minimize exposure to air, and the storage area should be dry, clean, and free from any strong odors. This helps preserve the quality and flavor of the tea over time.
For everyday storage, you can use ordinary bottles or cans. To reduce air exposure, consider using a double-layered container—such as a small pot inside a larger one. Ensure that the lid fits tightly with the container body to prevent moisture from entering. This simple method can significantly extend the shelf life of your tea.
If you have access to a vacuum pump, you can place the tea in a sealed tank, remove the air using the pump, and then weld the tank shut for an airtight seal. This technique can help preserve the tea for up to two or three years. If vacuum equipment is not available, you can use a hot water bottle (gall bladder) instead. Fill the bottle with tea leaves, seal the lid tightly, and then cover it with white wax and tape. This method is easy to do at home and provides good protection against moisture and air.
Cold storage or refrigeration is another effective way to store tea. However, it's crucial to ensure the tea is well-sealed before placing it in the fridge. This prevents moisture and odors from the refrigerator from affecting the tea.
Another technique involves drying the tea to a moisture content of around 2% before sealing it in a container. Once sealed, the tea can be stored at room temperature for one to two years. This method works best when the tea is fully dried and kept in a stable environment.
Using desiccants like quicklime or silica gel can also enhance the preservation of tea. For example, wrap the quicklime in a double layer of white cloth and mix it with the tea, which is wrapped in thin kraft paper. Place them together in a jar or barrel in a ratio of 6.5:1. Make sure the lime is placed in the center of the container. Seal the jar with kraft paper and cover it with a straw mat. Store it in a dry, cool place. When the lime becomes damp and loses 80% of its effectiveness, replace it. Typically, new tea requires lime replacement after about three months.
When using silica gel, monitor its color change. If the blue particles turn translucent, reddish-white, or white, they need to be reactivated by sun-drying or gently heating them until they return to blue. This makes silica gel a cost-effective and reusable option for long-term tea storage.
By following these methods, you can effectively maintain the quality of your Sheng tea and enjoy it for a longer period.
