Tea Storage

I did a web search on the subject of tea storage and like most searches, what I discovered was a lot of conflicting information. What a surprise. It isn’t that complicated. The rules for storing tea are kind of like the rules in the movie Gremlins. Don’t expose them to light, don’t get them wet and never ever feed them after midnight. Ok maybe the rules are a little different. Mostly you just need to use common sense. The idea is to avoid exposure to heat, light, air, odors, and obviously moisture. Simple isn’t it?

Heat, light, and air will cause the tea to become stale before its time, losing its flavor. Think of it like crackers. You open the cellophane and leave them on the counter, when you go back to get one later it is no longer an enjoyable experience. Ideally tea should be stored in a cool place in an airtight non-clear container. Clear is ok if you are putting the container in a cabinet as this will block the UV rays.

Some people put their tea in the refrigerator or freezer in order to keep it cool. The more I read on this subject, the more I have become convinced this is not a good practice. Have you ever grabbed some ice cubes out of the freezer and thought to yourself these taste like leftovers? Well that is one of the problems with storing tea in the fridge. Refrigerators are full of odors and tea is an excellent absorber or odors. You may have the tea in a waterproof container but that does not mean it is airtight or odor proof. For this reason, don’t store tea near spices or coffee.

Intentionally adding water to tea leaves creates a wonderful drink. Small unintentional amounts of moisture added to tea leaves can cause it to rot or mold. Try leaving your used tea leaves in a cup and see how long it takes them to turn blue and fuzzy. Not a pretty picture is it? Keeping tea in the refrigerator can cause it to absorb moisture through condensation. Lots of experts will disagree with me here but I don’t think it is worth the risk. Using the cracker analogy again, you wouldn’t store a box of crackers in the refrigerator and expect them to remain fresh so why would you store your tea there?

Even in the pantry an unopened box of crackers will eventually go stale. Tea will do the same. Tea does have a shelf life even when properly stored; so how long will it remain fresh? On various websites I have seen loose-leaf tea blends with ranges from a couple months to a year for green tea and up to two years for most black teas. That’s quite a range. Prepackaged tea has an even longer useful lifespan marked on the box often up to three years.

Tea Bag Storage

Prepackaged bagged tea remains pretty stable for quite some time if you take care of it. If the tea company tells you their product is good for three years, it will probably be good for a little while longer. They are not likely to chance turning you off to their tea by selling it to you stale.

I just recently discovered some Bigelow tea in the back of my cupboard that I had forgotten about. It had expired long ago according to the date on the box. The teabags were sealed in individual foil wrappers so I thought I would brew it and see how badly it had deteriorated. To my surprise it tasted just like I remembered. It had been kept in a dry airtight environment all that time and survived very well. I am not suggesting this is good practice; just stating tea is more resilient than is often stated.

So how should you store your teabags? I usually leave them in the original box. The majority of the boxes I buy come with the bags sealed in individual foil wrappers. I feel this offers the longest possible lifespan. Some come in a recloseable bag. One brand I use has the bags packed in a zip-lock bag. The rest come with the bags either in paper envelopes or loose in the box. The last category (paper envelopes or loose in box) are the most likely prepackaged teas to go stale once the shrink-wrap is removed from the box. Even then, unless you have too many boxes open at once, you may not have problems if you keep the box closed to minimize the air circulating around the bags.

If you have destroyed the lid or have more bags than you can comfortably use in a reasonable amount of time put them in a canister with a tightly sealing lid. Short term a zip-lock bag, or tea chest, are acceptable options. This should increase the useful lifespan of your tea. However, note that if you store various unsealed teabags together in the same bag or chest the flavors may mingle.

Loose Leaf

The biggest threat to the lifespan of your tea is most likely inadequate packaging or improper storage resulting in too much exposure to air. Every time you open the container you expose the entire batch to air and light. Buying in bulk can be a lot less expensive. Buying in smaller quantities is less likely to result in stale tea. What to do? One thought is to buy in bulk and divide the tea into smaller more manageable amounts that are kept sealed in separate containers. One for long term storage and a smaller one for everyday use.

Some people use zip-lock bags to hold their tea. For short-term storage maybe this will work be aware that the bags are not odor proof or necessarily air tight.

Avoid plastic unless you are sure it is odor-proof. I’ve read of a good test for this is to seal up the container and leave it a few days. Now open it and smell the insides. If it has an odor, don’t use it unless you want your tea tasting like that smell. Plastic should also be avoided unless you know it is safe for food storage. They need to be BPA free.

Many brands of loose-leaf tea come in a metal tin. This is a great option and I recommend you keep the empty tin for future use. Some teas come in a bag. Keep it sealed as best you can. If it is a resealable mylar or similar heavy duty bag it should keep well. If it is a lighter weight bag it will probably start to break down or tear at some point before you have emptied it so you might consider putting it in something else to start with. I often use the bag for short term use and store the biggest portion of the tea in a something else.

Besides the tea tins previously mentioned ceramic, glass, and metal canisters will work well if they have a good sealing lid. If glass is used it should not be clear. Green or brown glass work well to prevent UV rays from breaking down the tea. I use a stainless steel canister from Wal-mart for my loose-leaf tea.

No matter what you choose to store your tea in avoid leaving it sit on a counter where it could be exposed to sunlight coming through a window. Even inside a tin, it won’t take but a few hours to destroy the contents. Remember, the idea is to avoid exposure to heat, light, air, odors, and moisture

  3. Thank you for all this information. I am a big-time tea drinker :) I discovered a box of Barry's Irish Breakfast tea a friend gave me a long time ago I set it aside in a panty in the garage, still cellophane wrapped. The expiration date was 12/2015. I feared I was too late to enjoy it. My friend found it too strong for her, But I drink my tea dark and strong. I have often received a coffee "refill" at restaurants! I, too, add sweetener to my tea. This tea may not have its finest, original flavor, but it is still full-bodied. A little too astringent for my tongue, I needed to add a little more sweetener and now it is better, but not a favorite. Thank you for letting me know it was safe to try.

  6. Does tea expire? Yes and no. Expiry date depends on a type, storing conditions, freshness of tea and many other factors. Let's start with the basics.
