Tea quality does not end at the point of purchase. How tea is stored at home plays a major role in how it tastes in the cup, sometimes more than brewing technique itself.
Assam tea, in particular, is prized for its rich aroma, malt depth and full body. But exposure to air, light, moisture and heat can quickly dull these characteristics if tea is not stored correctly.
This guide explains how to store tea properly, why it matters, and how small changes can help preserve the flavour, aroma and integrity of Assam tea and herbal infusions alike.
For a broader understanding of Assam tea’s origin, craftsmanship and character, our Ultimate Guide to Assam Tea offers the full story behind the leaf.
Why Proper Tea Storage Matters
Tea leaves are naturally aromatic and highly absorbent. This means they react easily to their environment.
When tea is exposed to oxygen, humidity or strong surrounding smells, its flavour compounds slowly degrade. Over time, this results in a flat, stale or lifeless cup, even if the tea was originally high quality.
Storing tea properly helps maintain freshness, protect volatile aromas and ensure that each brew reflects the character intended by the grower and maker.
The Five Enemies of Tea Freshness
All teas, whether black, green or herbal, share common storage sensitivities.
- Air causes oxidation, which dulls flavour over time.
- Light, especially sunlight, degrades delicate compounds.
- Moisture introduces staleness and can damage leaf structure.
- Heat accelerates flavour loss.
- Odours from surrounding foods or spices can be absorbed into the tea.
Understanding these factors makes it easier to store tea in a way that preserves its quality naturally.
How to Store Assam Black Tea
Assam black tea is relatively robust compared to green tea, but it still benefits from thoughtful storage.
The best approach is to keep black tea in an airtight container, stored in a cool, dark place away from heat sources such as ovens or windows. Metal tins with tight-fitting lids or opaque, resealable pouches work particularly well.
When stored correctly, high quality Assam black tea can retain its character for many months, allowing its malt richness and body to shine.

How to Store Assam Green Tea
Green tea is more delicate and sensitive than black tea due to its lighter processing.
Assam green tea should always be kept tightly sealed and protected from light and heat. Once opened, it is best consumed sooner rather than later to enjoy its fresh, clean profile.
Avoid storing green tea near spices or coffee, as it easily absorbs surrounding aromas. Proper storage helps maintain its smoothness and prevents bitterness from developing over time.

How to Store Earl Grey Tea
Earl Grey tea requires special consideration because of its aromatic oils.
The bergamot oil used to scent Earl Grey is volatile, meaning it fades more quickly if exposed to air or light. For this reason, Earl Grey should always be stored in a fully airtight container, away from heat.
Storing Earl Grey correctly helps preserve its distinctive citrus fragrance and prevents it from becoming muted or flat.
How to Store Herbal Teas
Herbal tea infusions such as chamomile, hibiscus and blue tea are not made from the tea plant, but they are just as sensitive to their environment.
Whole flowers and petals should be kept dry and airtight to prevent moisture absorption. Because herbal teas are naturally aromatic, they should be stored separately from strongly scented items.
When stored properly, herbal teas retain their colour, aroma and gentle functional qualities, making each cup as enjoyable as intended.
Should You Store Tea in the Fridge?
This is a common question and the answer is generally no.
Refrigerators introduce moisture and fluctuating temperatures, which can harm tea leaves. Unless tea is vacuum sealed and stored under very specific conditions, refrigeration often causes more harm than good.
A cool cupboard away from heat and light is almost always the better choice.
How Long Does Tea Stay Fresh?
Tea does not usually spoil, but it does lose vibrancy over time.
Black tea typically stays fresh for longer than green tea, while herbal teas fall somewhere in between depending on the ingredient. The key factor is not the date but how the tea has been stored, which affects the smell and taste when brewed.
If a tea has lost its aroma or tastes flat, storage conditions may be the reason.
Freshness, Quality and the Assam Difference
High quality tea rewards care. Assam teas grown, harvested and processed with attention to detail deserve storage that protects that effort.
At Dehing Tea, freshness begins at our estate, from plucking the fresh tea leaves through to quick processing in our on-site tea factory, ensuring the tea is kept fresh through production and careful packaging. Proper storage at home completes that journey, ensuring that each cup reflects the richness, balance and integrity of the leaf.
Understanding how to store tea properly is one of the simplest ways to elevate your daily tea experience.
