If tea is not stored properly, it can easily lose its fragrant aroma. If you have the habit of drinking tea, you should aim to buy and consume it fresh. For tea stored at home, pay attention to the following 4 points:

Avoid Moisture

When the moisture content of tea reaches 8.8%, it may develop mold; at 12%, if the temperature is suitable, mold can rapidly multiply, leading to visible mold spots on the tea leaves. Therefore, do not store tea in damp environments like the kitchen.

Cool and Dark

Both sunlight and artificial light can affect the quality of tea. The higher the grade of green tea or scented tea, the more sensitive it is to light. Thus, avoid placing tea near windowsills or under spotlights.

Store Separately

After purchasing, wrap the tea in paper, then seal it with two layers of polyethylene food-grade bags before placing it in a dry location. Never store tea together with strong-smelling items such as mothballs, soap, perfume, or cigarettes.

Tin or Porcelain Containers are Best

Tea is best stored in tin or porcelain canisters. The next best options are iron boxes, wooden boxes, or bamboo boxes. Plastic bags or cardboard boxes can also be used. If using an iron box, ensure it is kept in a cool place away from direct sunlight to prevent the box from rusting and to slow down the tea's deterioration. Thick, food-grade plastic bags are also a viable option for storage.
