Does Tea Expire? How to Store Your Tea So It Lasts Longer

October 21, 2021

Although loose leaf tea is not perishable, tea does expire.

In fact, by the time most tea hits the supermarket shelves, those teas are already old and past their prime. 

What does this mean for tea lovers who want to know how long their teas should last?

We talked to the tea farmers themselves to find out how to store tea properly, how soon to drink tea after picking, and which teas actually get better with age.

Freshness matters. Fresh tea tastes sweeter, and fresh teas are more aromatic, more complex, and packed with more antioxidants. That's why everyone goes crazy for fresh spring tea, and that's why so many tea lovers want to make sure their favorite teas do not go bad. 

Luckily, expired tea is something you can avoid if you know what to look for and how to store your tea properly: seek out teas that list their picking date with transparency and keep your tea away from light, heat, and moisture to keep them tasting great.

Can Tea Expire?

To answer this question, it is important to understand what a tea expiration date really means. The expiration date printed on a tea package does not actually tell you if a tea is fresh or not. Instead, the expiration date on a bag of tea only shows how long the seller is willing to take responsibility for consistency and for product safety, not how long the tea actually tastes good.

So, does tea go bad? Not exactly. High quality tea kept dry and sealed is safe to drink indefinitely. In fact, that’s why people crafted tea in the first place - fresh tea leaves can’t last as long as teas that have been crafted into green tea, black tea, oolong tea, and others.

However, while good tea does not go bad, it can go downhill, losing sweetness, complexity, and antioxidants as the leaves undergo a variety of chemical changes - especially if your tea is left out.

Lighter teas like green tea “expire” the fastest, while black teas and roasted oolongs hold their flavor and quality much longer. Some teas like pu’er are finished in a special way that lets them actually get better with age, like wine.

How Long Does Loose Leaf Tea Last?

Before you worry about how long a tea has been in your cupboard, consider how old a tea might be before it even reaches the shelf. Most tea stores do not source teas directly from the farmers growing and making their teas. Instead, teas pass through layers of distributors and importers around the world, and this means teas can easily be over a year old before you even buy them.

On the other hand, teas coming directly from small family farms are more likely to be fresh and flavorful. Direct sourced teas provide clear picking dates, and these teas have a much shorter journey from the farm to your cup. 

In general, your tea should taste great for about one year after it was picked. Different tea styles do have different shelf lives, but if you get a fresh tea and you store it carefully, you can get the most out of your tea while it is still good. 

How Long Does Black Tea Last?

The first black teas came from Wuyishan, China, and became an overnight hit in Europe thanks to their long shelf life. Black teas are fully oxidized - this gives them a longer shelf life than green tea, as well as sweet and malty flavors. 

Because of oxidation, quality black tea can last for two years, and certain aged black teas can be enjoyed even longer. 

  • • Always look for loose leaf black tea with a picking date listed

  • • Drink black tea within two years to enjoy their full flavor and aroma

  • • Expect aged black tea to take on deep woody flavors

Does Oolong Tea Expire?

Green oolongs are meant to be enjoyed within one year, while roasted oolongs can generally last for two years. Some oolongs are actually finished with aging in mind and last for decades, getting better, like wine. It all depends on how the tea was crafted.

  • Greener oolongs are aromatic and hyper seasonal. 
      Make sure to choose teas with clearly listed picking dates

  • • Most roasted oolongs are allowed to rest for a few months after they are crafted.
      Once release, roasted oolongs last for about two years

  • Aged oolong teas are crafted specifically to last decades.
     Look for aged oolongs with a clear age statement

How Long Is Pu’er Tea’s Shelf Life?

Pu’er (普洱) - sometimes spelled pu erh or pu-er - was an accidental discovery that proved some teas can actually become even better with age. Pu’er teas do not expire, and both sheng pu’er and shu pu’er are prized for the complexity they can develop over decades.

Interested in aging your own pu’er? Explore our top picks, and follow these tips:

  • Avoid big factory labels that do not disclose their growers and sources

  • Look for pu’er from small family workshops and biodiverse plots

  • Good in, good out: pu’er with aging potential should also taste great when it is young

Does Green Tea Expire?

Green tea has the shortest shelf life of all teas. Fresh seasonal green tea is sweet - not bitter - and deeply aromatic. It can last for up to a year but, because green tea does “go bad,” it is best to drink green tea within six months.

  • Look for seasonal green tea that lists both picking date and farmer

  • Drink spring harvest in the spring and autumn harvest in the autumn

  • Use older green tea for cold brew or cooking

How Long Does White Tea Last?

White tea is finished to lock in the freshest “tea” flavor possible, and well made white tea lets the natural flavor of the fresh leaves shine for months after picking. For fresher, green flavor, drink white tea within one year of harvest

White tea can also be aged and - if properly stored - white tea does not expire. Instead, well-crafted white tea can develop deeply woody and herbaceous flavors over time.

  • For fresh, sweet, floral flavors, drink white tea within a year of picking

  • After a year of aging, white tea becomes darker and more toasty

  • After many years of aging, white tea becomes cooling and spiced

Does Herbal Tea Expire?

Herbal tea’s shelf life is no different than green tea. Since most herbal teas (also called tisanes) are generally finished through simple drying, they are not ‘heat-fixed’ like black teas. Therefore, herbal teas are best brewed within a year of picking

Some tea farmers - like the He Family in Laoshan and the Zhenyuan Dongsa Cooperative in Qianjiazhai -  are applying experimental tea craft to herbal teas. This additional craft extends the shelf life of our partners’ herbal teas

  • Look for herbal tisanes that say when they were picked

  • Try herbals from farmers that are applying tea finishing techniques to herbal tea

  • Use stale herbal tea for mixed drinks and cooking

How to Store Loose Leaf Tea

So you’ve found some great teas - congratulations! Now you might be wondering about the best way to store loose leaf tea so that it lasts as long as possible. This part’s easy!

Keep your tea away from light, moisture, and heat. Tea goes bad if it is left out.

Fun fact: Tea professionals are so concerned about the way the environment changes a tea that even teaware for tasting is regulated for competition judging to keep everyone on the same playing field.

How to Store Green Tea and Green Oolong

Green tea and greener oolong teas are the most delicate and seasonal teas. Proper storage locks in their sweet flavors and aromas. A little effort means better tea for you year-round:

  • Protect tea from air and moisture: Do not let your tea oxidize. Instead, store green tea and greener oolong teas in an airtight container to keep your tea fresh.

  • Protect green teas from light: Do not use glass canisters to store your tea. Light can damage your tea and decrease its shelf life, so choose your material carefully and keep storage containers away from direct sunlight.

  • Protect teas from heat: If it’s too hot for you, it’s too hot for the tea. Heat accelerates chemical changes, so store your tea away from direct heat sources.

  • Enjoy green teas when they are fresh: Drink your most seasonal teas in the season they are picked to get the most out of them. Don’t save them - drink them!

How to Store White Tea, Black Tea, and Dark Oolong

Not all loose leaf teas go bad.

White tea, black tea and roasted oolong tea can last for several years if they are properly stored, and well-made teas can even become deeper and more complex over time. All you need to do is follow the same basic storage guidelines you would with green tea:

  • Moisture is the enemy: Moisture control is very important to aging white tea, black tea and oolong. Keep your teas airtight!

  • Protect teas from light: Glass may be pretty, but if your teas are left in the sun, you will have stale tea!

  • Protect teas from heat and cold: Heat promotes chemical changes and can “overcook” teas, while cold creates conditions for condensation, moisture, and even mold.

  • Enjoy your tea for years: Proper storage means you do not need to worry about your favorite tea going bad.

How to Store Pu'er Tea

When thinking about tea shelf life and the best way to store tea, pu’er tea breaks all the rules. Pu’er is made specifically to age for decades, and unlike other teas, pu’er tea is not sensitive to air or controlled moisture. In fact, pu’er tea requires some air flow and ambient humidity to continue aging. 

Properly stored pu’er tea is an investment that yields deep, complex brews over time.

  • Pu’er likes the same weather you do: Keep your pu’er happy with stable room temperature and comfortable humidity. Aim for 65-74 F and about 40%-65% humidity. 

  • Don’t seal your pu’er: Pu’er needs airflow to keep aging and to protect against mold

  • Protect from strong smells: Keep your pu’er away from spices and the kitchen or it will absorb those smells in the air. Linen closets or office drawers work well.

  • Do not drink moldy pu’er: if you notice white mold spots on your pu’er, throw it away. Pu’er stored with too much humidity and condensation can go bad, so avoid storing your pu’er in basements, bathroom closets, or similarly damp environments. 

How to Tell If Tea Is Still Fresh

It’s easy to tell if you have stale tea. Simply open your bag or canister and smell. 

If you cannot smell anything, then the tea is stale. 

All good tea is aromatic. Most of our sense of taste is tied to smell. If the tea has no aroma left, it has no flavor left, and it’s time to shop for fresh tea.

What to Do With Old Tea

Can you drink expired tea? Of course! 

If the tea was made and stored safely, it is still safe to drink, even if it’s old. 

The best way to use stale tea is to find a recipe that relies more on the tea’s texture as a background note and less on showing off big aromatics.

Our top picks include using the tea in homemade chai, cold brewing big batches of iced tea for summer sipping, or even using the tea in recipes like ochazuke.
