Green Tea is a popular type of Tea, but it typically has a short shelf life and requires proper storage. Here are some methods for storing green tea:

How to Store and Preserve Green Tea

To preserve the freshness of green tea, consider the following:

1. **Refrigeration:** Store green tea in the refrigerator. Place the tea leaves in an airtight container and then put them in the fridge. This slows down the oxidation process and keeps the tea fresh.

2. **Humidity Control:** Green tea is susceptible to moisture, so it's important to keep it dry. Store the tea in an airtight container in a dry, well-ventilated area away from direct sunlight.

3. **Avoiding Odors:** Tea can easily absorb odors due to its strong adsorption capacity. When storing green tea, avoid keeping it near items with strong smells and store it in a scent-free environment.

4. **Avoiding High Temperatures:** High temperatures accelerate the oxidation process, leading to spoilage. Keep green tea away from high temperatures, such as direct sunlight or near heat sources like stoves.

5. **Regular Inspection:** Regularly check the expiration date and quality of the tea. Discard any spoiled tea promptly.

Specific Methods for Storing Green Tea

First, organize the green tea and place it into aluminum foil bags, squeezing out excess air and sealing the bag tightly. Then, place the sealed bag in a metal tin and close the lid securely before refrigerating.

If the green tea is already sealed, you can directly refrigerate it at a temperature between 0-10°C. Be sure to separate it from any items with strong odors in the refrigerator and prevent moisture from entering.

Note that after removing the tea from the refrigerator, do not open the packaging immediately to prevent moisture absorption.

The correct procedure after removing the tea from the refrigerator is: let the green tea slowly warm up to room temperature before opening the package and brewing. The optimal time for consumption is within half a month.

Two Methods for Household Tea Storage

1. **Room Temperature Storage Method**

For teas intended for consumption within one month, use metal containers like iron or stainless steel cans, or tins made of dense materials like tin. Place the tea in a bag and then into the can, securing the lid. Store the metal container in a cool place.

Avoid placing it in areas exposed to direct sunlight, strong odors, humidity, or heat sources.

2. **Refrigerated Storage Method**

For long-term storage exceeding two months, first place the tea in aluminum foil bags and squeeze out the air, then place the bagged tea in a container and seal it before refrigerating. Avoid frequently opening the container; prepare a two-week supply of tea for daily use and store the rest in the refrigerator.
