Black Tea, being a fully Fermented tea, typically has a shelf life of 18 months for loose-Leaf varieties; sealed cans or aluminum foil packaging can extend this to 2–3 years. Additionally, the shelf life is influenced by the production method: if traditionally charcoal-baked, black Tea can be preserved for an additional 6–12 months, allowing a total storage period of 3–5 years.
One. Plastic Bag Storage
Storing tea in plastic bags is simple and convenient, a common method. The bags used should be clean, odorless, and undamaged. First, wrap the tea in kraft paper before placing it in the bag.
Two. Tin Can Storage
Tin cans provide excellent moisture protection and sealing, making them ideal for storing tea. When placed in a tin can, the tea retains its aroma and remains dry even in humid weather. After filling the can with tea, seal the opening with tape and store it in a dry place.
Three. Porcelain Jar Storage
Porcelain jars are airtight, making them a standard tool for tea storage. Before putting the tea in the jar, ensure there are no odors inside and that it is clean. Before placing the tea in the jar, wrap it in small packets using thick kraft paper. Then, include a small bag of lime in the jar.
Four. Thermos Storage
In addition to their excellent heat retention, thermoses are also great for storing tea. Ensure the thermos is dry before placing the tea inside. Fill the thermos completely to prevent air from entering. Once filled, tightly seal the thermos mouth, seal the edges with beeswax, and wrap with tape.
Five. Low-Temperature Storage
This method is straightforward: after sealing the tea in a metal can, wrap it in a plastic bag and seal it, then store it directly in a freezer at around -5°C. Storing black tea in this manner keeps it fresher.
Storage Precautions for Black Tea
1. Avoid Light: Do not place the container holding black tea in direct sunlight. Store it in a cool, dry place. Direct sunlight can degrade the components in the tea, altering its color and flavor.
2. Low Temperature: As black tea is fully fermented, low-temperature storage is recommended, such as sealing it and keeping it in the refrigerator.
3. Maintain Dryness: Drying is the final step in black tea production, so the tea readily absorbs moisture. Moisture absorption can degrade the tea's quality and cause mold growth.
4. Sealed: Ensure the tea is stored in a sealed container. Exposure to air can cause oxidation, which degrades the tea's quality.
5. Prevent Odors: If stored near strong-smelling items, black tea can easily absorb these odors, compromising its quality and rendering it unpleasant or even unsafe to drink.
