This is a practical tea storage manual tailored for ordinary people, aiming to guide you in using simple techniques to properly store tea and prevent spoilage and waste:
I. The Four Archenemies of Tea Storage
1. Humidity: Tea is hygroscopic and prone to mold and spoilage in damp environments.
2. Temperature: High temperatures can accelerate tea oxidation, leading to the loss of aroma.
3. Odors: Tea easily absorbs surrounding smells, such as kitchen smoke or perfume.
4. Light: Direct sunlight can damage the components in tea.
II. General Rules for Home Tea Storage
1. Strictly Sealed
– Recommended containers:
– Food-grade aluminum foil bags (ensure tightly sealed) + clip seals
– Sealed jars with rubber rings (glass, ceramic, or stainless steel)
– Avoid using: regular plastic bags, paper bags, open-top cans
– Storage tips: For long-term storage, place in food desiccants (avoid direct contact with tea).
2. Avoid Light and High Temperatures
– Storage location: Choose a cool and dry place, such as inside cabinets or drawers
– Avoid placing near: heaters, stoves, balconies, or windows
3. Isolate Odors
– Precautions: Keep away from kitchens, bathrooms, and cosmetic storage areas, avoid mixing with spices or dry goods (such as star anise, cinnamon).
4. Divide and Store
– Advice: Divide large quantities of tea into smaller portions (e.g., 50-100 grams per pack) to reduce frequent opening and air exposure.
III. Storage Tips for Different Types of Tea
Tea Type Storage Key Points Suitable for Refrigeration
Green Tea, Yellow Tea Prevent oxidation, need to maintain freshness Sealed and refrigerated (0-5°C)
White Tea, Pu-erh Tea Promote natural transformation, maintain appropriate ventilation Stored in a cool and dry place at room temperature
Black Tea, Oolong Tea Sealed at room temperature, avoid light No need for refrigeration
Dark Tea (Brick Tea, Tuocha) Moderate ventilation, keep original packaging Avoid excessive sealing
IV. Avoiding Storage Misconceptions
1. Is all tea suitable for storage in the refrigerator?
– White tea, dark tea, and Pu-erh tea can become damp when refrigerated, affecting later transformation.
– Only green tea and light-flavored oolong tea require refrigeration.
2. Can transparent glass jars be used to store tea?
– Light exposure can accelerate tea spoilage, so it is recommended to use opaque containers.
3. Tea left unconsumed for a long time after opening
– It is best to consume tea within 3-6 months after opening to prevent dampness.
V. Signs of Tea Spoilage
– Visual: The color becomes dull, and mold spots appear.
– Olfactory: The original tea aroma is lost, and musty or sour odors appear.
– Tactile: The tea becomes soft (moist), and there is no crisp sound when crushed.
VI. Purchase Suggestions
1. Buy in moderation: It is recommended for ordinary families to purchase tea based on consumption over 3-6 months.
2. Preference for small packages: It is advisable to choose individually small-pouched packages first, as they are convenient for storage.
