How to store tea at home

For everyday storage, keep tea dry, clean and protected from light, heat and other smells. Start with the label: the storage method and shelf life depend on the particular tea and packaging.

Steps

Choose a place and check the container. Use a cool, dark cupboard away from the stove, steam, radiators, spices and cleaning products. A kitchen cupboard can work if it is not hot, damp or strongly scented. Choose a tightly closing food-safe pouch or a clean, dry, odour-free container. Glass is fine inside a dark cupboard; metal or glazed ceramic works if the lid fits well. Paper alone offers little protection against moisture and smells. An opaque outer bag does not make up for damaged inner packaging.
Keep a small daily supply. For a large reserve, set aside a small amount for the coming weeks and close the rest tightly. Use a dry spoon, keep the open bag away from kettle steam and close it promptly. Retain the name, batch number and label dates, and note when you opened it. Keep different teas in separate closed packs, especially scented and smoked teas.
Use cold storage when appropriate. Cold can help preserve some green and yellow teas and light oolongs. If the producer recommends it, store reserves in small airtight portions protected from smells. Let the entire closed pack reach room temperature before opening; otherwise moisture in the air can condense on cold leaves. Do not open a cold pack for every cup. A tightly closed daily portion is easier to use in a cool cupboard unless the instructions say otherwise. Freeze only when recommended for that product.
Protect white tea and pu-erh from damp too. White tea can be kept tightly sealed, including for ageing. Pu-erh does not need to sit open or in a draught: a food-safe outer bag around the paper-wrapped cake helps protect the tea from moisture and smells. Conditions influence how tea changes, but sealing does not instantly stop every process. Do not add water or create damp conditions to speed up ageing. White tea, pu-erh and other teas do not automatically improve each year.
Distinguish faded aroma from spoilage. A faint aroma alone does not mean mould. But if tea has become wet, developed suspicious growth or acquired a musty, mouldy smell, do not taste it to check. Rinsing, boiling water and pan-toasting cannot reliably make it safe. If only the aroma has faded and storage and condition give no cause for concern, try brewing normally. Heating cannot restore lost compounds and may simply add a roasted taste.

Questions and answers

How long does opened tea keep?

There is no single period for every tea. Follow the producer’s instructions and consider packaging, moisture and temperature. Buy an amount you can enjoy while it still tastes good; see the shelf-life guide for more detail.

Do I need a particular room humidity?

For an everyday supply, the priority is keeping dry tea from taking up moisture. Room humidity does not tell you the condition of leaves inside a pack. A universal 50–70% setting cannot replace suitable packaging and attention to storage conditions.
