Storing tea well is the difference between a fresh, vibrant cup and a flat, stale one. The four enemies of tea are the same across every type: light, heat, oxygen, and moisture. Get those four right and your tea will hold its flavour for the full shelf life. Get them wrong and even the best tea will fade fast.

The good news is, proper storage doesn't need anything fancy. A cool, dark cupboard, a sealed container, and a dry spoon are all you really need.

The four things to protect tea from

Light. Especially direct sunlight. UV breaks down chlorophyll, which is what gives green teas their colour and a lot of their flavour. Even bright indoor light over weeks will dull tea. Store in opaque containers or in a closed cupboard.

Heat. Above 20 degrees Celsius, the delicate amino acids and aromatic compounds in tea start to break down. Keep tea away from the stove, oven, kettle, dishwasher, and any sunny windowsill.

Oxygen. Once a pack is opened, oxygen starts oxidising the leaf compounds, dulling colour and aroma. Reseal tightly between uses. The original Teafy canisters and pouches are designed with this in mind, so just keep them closed when you're not scooping.

Moisture. The biggest enemy. Even small amounts of moisture clump tea, accelerate spoilage, and can lead to mould in the worst cases. Always use a dry spoon. Never store tea above the kettle or anywhere steam reaches.

Storage by tea type

Loose leaf green tea (Asamushi Sencha, Fukamushi Sencha, Genmaicha): store in a sealed, opaque container in a cool, dark cupboard. Drink within 6 to 9 months of opening for best flavour. Unopened, good for around 12 months from manufacture date.

Roasted tea (Hojicha loose leaf, Hojicha powder): store sealed and dry. Roasted teas are slightly more forgiving than green teas because the roasting process stabilises some of the more delicate compounds, but light, heat, and moisture still degrade them. Drink within 6 to 12 months of opening.

Matcha and powdered tea (Ceremonial Grade Matcha, Kyoto Uji Matcha, Hojicha Powder, Yuzu Matcha, Superior Culinary Grade Matcha): store sealed in a cool, dark place. Drink opened matcha within 30 days for best flavour. Unopened, good for around 12 months. For a deeper guide on matcha storage specifically, see our matcha-specific question linked at the bottom.

Should you refrigerate or freeze tea?

For unopened tea, refrigeration or freezing can extend shelf life beyond 12 months. Just bring the can or pouch to room temperature before opening, otherwise condensation will form on the leaves the moment you crack the seal, which is exactly the moisture problem we're trying to avoid.

For opened tea, do not refrigerate. Every time you take the container out of the fridge to use it, condensation forms on the leaves. That moisture builds up over time and accelerates spoilage. A sealed container in a cool cupboard is better for opened tea than the fridge.

Common storage mistakes

Storing tea above the stove, kettle, or oven. The combination of heat, steam, and indirect light is brutal. Even high cupboards near these appliances are too hot.

Decanting into clear glass jars on display. They look beautiful, but they expose tea to constant light. If you want display jars, use opaque ceramic or dark glass.

Using the same wet teaspoon between brews. Even a tiny amount of moisture from your last cup will sit in the can and slowly degrade the tea around it.

Leaving the lid off while you brew. Even a few minutes of open air exposure adds up over a few weeks. Reseal as soon as you've scooped.
