Tea goes bitter when the leaves stay in it. That is the whole problem a one-cup tea maker solves: you brew in one place, then separate the leaves from the water when you decide it is ready, rather than when the mug is finished. A tea bag does that too, but it does not give you loose leaf.
Our tea infuser mug guide covers mugs with a basket inside, where you lift the basket out. This page is about brewers built for one person, mainly those that drain, press or lock the leaves away, and we have limited it to glass and stainless steel. The popular bottom-dispensing plastic models are good tools, but we left them out on purpose, and we explain why below.

Quick verdict: which one cup tea maker to buy
Buy the ZENS One Touch Tea Maker, 9 oz if you want the true one-cup idea: press once, the tea drops into a glass mug and the leaves stay behind. Choose the Hario ChaCha Kyusu 300 ml for a simple glass pot. The FinalPress Original is the stainless, portable option, and the Adagio ActiviTEA is the glass one to carry to your desk.

Our picks for the best one cup tea maker
We searched for independent reviews of these small brewers and found none we could cite for any of these models. What came up was about automatic machines and iced tea makers. So each write-up here rests on the listing and the maker’s own details, and we do not claim anything about how the tea tastes. Sizes vary more than the name suggests, and a one-cup brewer can hold up to 17 ounces, so we give the listing’s number for each.
1. ZENS One Touch Glass Tea Maker, 9 oz – Press Once, Leaves Stay Up Top
ZENS built this around the idea this page is about. You add leaves, pour in hot water and steep, then press once. The tea drops into the 9-ounce insulated mug below, and the leaves stay in the top with no more contact. That is the fix for over-steeping, without a basket to fish out.
It is borosilicate glass with a 316 stainless steel microfilter, which the listing says has more than 1,600 fine holes, so small leaves should stay put. This version comes in the walnut color. ZENS sells mostly on Amazon, so treat it as one of our two such brands here, and check parts availability if the seal ever wears.
The listing is honest about one limit: this is a portable brewing system, not a leak-proof travel bottle or a thermos. Keep it upright, and carry it only as far as your desk.
Why we like it
- One press separates tea from leaves
- Glass with a 316 stainless filter
- Comes with a 9-ounce insulated mug
- Small enough for a desk
Key specifications

| Capacity | 9 oz |
| Body | Borosilicate glass |
| Filter | 316 stainless microfilter |

Why we recommend it
It suits someone who makes one careful cup at a time and wants the leaves out at an exact moment.
Skip it if you want to carry it in a bag; the listing says it is not leak-proof.
Pros and cons
Pros
- Stops steeping when you say
- No plastic basket to lift
- Tidy desk size
Cons
- Glass needs care
- Amazon-first brand
- Small for a big mug drinker
2. Hario ChaCha Kyusu Maru Tea Pot, 300 ml – A Small Glass Pot From Hario
Hario is a Japanese glass maker with a long record in coffee and tea, and this little pot is about as plain as tea gear gets. It holds 300 ml, a bit over 10 ounces, which makes one decent cup. A large strainer lets the leaves open, and because you pour from the pot, the leaves stay behind.
The listing describes heatproof glass treated to resist shattering, and it says the pot is dishwasher and heat safe. It does not say whether it can go on a stove, so heat your water separately in a kettle.
Pouring is how you stop the steep, so you do need to pour it all out, and a small pot leaves no second cup waiting on the leaves. The seller we saw had an odd name for a teapot, GJG audio USA, so check the seller’s ratings and the return terms before you order.
Why we like it
- Holds about one cup at 300 ml
- Heatproof glass
- Large strainer lets leaves expand
- Dishwasher safe
Key specifications
| Model | CHJMN-30T |
|---|---|
| Style | Small glass pot |
| Capacity | 300 ml |
| Body | Heatproof glass |
| Filter | Large strainer, material not stated |
| How it stops the steep | Pour out |
| Care | Dishwasher safe |
| Warranty | Not stated |
Why we recommend it
It suits a tea drinker who likes watching the leaves and wants a small proper pot, not a gadget.
Skip it if you dislike third-party sellers; check who is selling it on the day.
Pros and cons
Pros
- Simple and easy to clean
- Good size for one
- Trusted glass maker
Cons
- Odd third-party seller
- Strainer material not stated
- Glass can break
3. FinalPress Original Coffee and Tea Maker – Stainless Press With a Plunger
FinalPress is mainly sold for coffee, but its listing names tea too, and for one reason it belongs here: it is hard to break. The body is solid 304 stainless steel, machined rather than stamped, and it packs small. You add loose tea, stir, wait and press the plunger.
The listing covers hot, iced and cold brew, with no paper filters or pods to buy. The brewing action is the same as a tiny French press, so the leaves are pressed and held rather than lifted out. The steep stops when you pour it off, so pour it all at once.
Most of the selling copy is about coffee, and the claim of more flavor than other brewers is the maker’s. We found no independent report on tea from this brewer. Capacity is not given in the features we read, so check the listing’s dimensions before you plan your mug around it.
Why we like it
- Solid 304 stainless steel
- Works for hot and cold tea
- No filters or pods
- Portable
Key specifications
| Model | 195893306367 |
|---|---|
| Style | Micro press |
| Capacity | Not stated |
| Body | 304 stainless steel |
| Filter | Press filter |
| How it stops the steep | Press and pour |
| Care | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits a traveler or camper who wants real loose-leaf tea and has already broken a glass brewer.
Skip it if you like to watch your tea brew, or want a brewer designed mainly for tea.
Pros and cons
Pros
- Hard to break
- No consumables
- Hot or cold
Cons
- Coffee comes first in the listing
- Capacity not stated in features
- Cannot see the tea
4. Adagio Teas ActiviTEA Portable Infuser, 10 oz – Glass, With a Carry Strap
Adagio is a tea company rather than a housewares brand, and this 10-ounce infuser and tumbler is its glass option for tea on the go. It is borosilicate glass and dishwasher safe, and a flexible strap lets you carry it from the kitchen to wherever you sit down.
The listing is very short. It covers those facts and little else, so we cannot tell you about the filter or how well the lid seals in a bag. Buy it as a brew-and-carry cup for a walk down the hall, and hold off on trusting it in a backpack until you have seen for yourself.
Adagio is also known for the IngenuiTEA, a bottom-dispensing brewer that drains straight into your cup. As far as we can tell from its BPA-free wording it is plastic, which is why it does not make this glass-and-steel list, and why this smaller glass model does.
Why we like it
- Borosilicate glass
- 10 ounces is one proper cup
- Dishwasher safe
- Flexible carry strap
Key specifications
| Model | 010049001 |
|---|---|
| Style | Portable infuser tumbler |
| Capacity | 10 oz |
| Body | Borosilicate glass |
| Filter | Not stated |
| How it stops the steep | Not stated |
| Care | Dishwasher safe |
| Warranty | Not stated |
Why we recommend it
It suits someone who steeps at home or the office and moves around with the cup.
Skip it if you want full details before buying; this listing says very little.
Pros and cons
Pros
- From a tea company
- Easy to clean
- Good size for one cup
Cons
- Very short listing
- Seal not described
- Glass can break
5. Bodum Travel Press, 15 oz – Insulated Steel That Pours Into You
Bodum’s Travel Press works like a small French press built into a travel mug. You add leaves and hot water, seal the lid, press the plunger and drink from the same container. It is double-wall, vacuum-sealed stainless steel that the listing says keeps drinks hot or cold for several hours.
There is one point to be plain about: because the leaves stay in the bottom, the tea sits on them after you press, so it keeps steeping a bit. Herbal blends and sturdy black teas forgive that more than a delicate green does. Pressing slows it, but pour off to stop it fully.
It holds 15 ounces, has a spill-resistant lid and a silicone grip, and is dishwasher safe. Bodum recently recalled some glass French presses, which we explain in the questions below. This steel travel press is not one of the models named.
Why we like it
- Vacuum-sealed double-wall stainless
- Spill-resistant lid
- Built-in plunger
- Dishwasher safe
Key specifications
| Model | 11057-01BUS |
|---|---|
| Style | Press mug |
| Capacity | 15 oz |
| Body | Stainless steel, double wall |
| Filter | Built-in plunger |
| How it stops the steep | Press, drink from same mug |
| Care | Dishwasher safe |
| Warranty | Not stated |
Why we recommend it
It suits a commuter who drinks a big mug of sturdy tea slowly and wants it to stay hot.
Skip it if you drink delicate green teas; pressed leaves stay in contact with the water.
Pros and cons
Pros
- Keeps hot
- Travel friendly
- Sold by Amazon
Cons
- Leaves stay in the mug
- Coffee flavor can linger if shared
- Extra lid no longer included
6. Teabloom Personal Tea Maker Cup – Double-Wall Glass, Lid as Rest
Teabloom calls this a personal tea maker, and it is the closest thing on this page to an infuser mug, so read our mug guide if that style is what you want. It earns a place because the kit treats brewing as a separate step: steep with the lid on, then lift the stainless basket out and rest it on the upturned lid.
The cup is double-walled borosilicate glass, which keeps tea warmer and the outside cooler, and the listing says an air-relief hole at the base makes it safe for the dishwasher and microwave. The basket is 304 18/8 stainless steel with laser-cut holes, roomy enough for leaves to expand.
Being a cup, its limit is simple: you have to lift the basket out at the right time. There is no drain or press step. Teabloom is a tea-gear specialist, sold here direct, and the listing is the source of everything above.
Why we like it
- Double-walled borosilicate cup
- 304 stainless steel basket
- Lid doubles as basket rest
- Dishwasher and microwave safe, per the listing
Key specifications
| Model | W32 / Q4 |
|---|---|
| Style | Cup with basket |
| Capacity | Not stated |
| Body | Double-wall borosilicate |
| Filter | 304 18/8 stainless basket |
| How it stops the steep | Lift basket out |
| Care | Dishwasher safe |
| Warranty | Not stated |
Why we recommend it
It suits someone who wants an easy daily cup with less to clean than a pot and no moving parts.
Skip it if you want the steep to stop on its own; a basket has to be lifted.
Pros and cons
Pros
- Few parts
- Stays warm longer
- Lid catches drips
Cons
- Close to a plain infuser mug
- Capacity not stated in features
- Double-wall glass can be fragile
7. Bodum Assam Tea Press, 0.5 Liter – A Press Sized for a Large Mug
The Assam is a tea press that brews in a glass pot. The listing says to press the plunger once the tea reaches the color and strength you like, with no infuser to take out. Bodum calls the half-liter a 4-cup pot, using a small cup measure. In ordinary terms it is about 17 ounces, or one big mug.
The listing describes a borosilicate glass body and a filter with an elastic silicone rim that keeps leaves inside. It suits loose tea and bags alike, by the listing’s account. Pouring it soon after pressing is still the safer habit with a strong tea.
Two things to check. The seller we saw was Amazon’s UK store, so check shipping and returns. And Bodum announced a recall of some glass French press coffee makers in October 2026. The Assam is not one of the named models, but look at the recall if you own Bodum presses.
Why we like it
- Press stops the steep
- Borosilicate glass body
- About a large mug at 0.5 liter
- Works with loose tea or bags
Key specifications
| Model | 1807-16 |
|---|---|
| Style | Glass tea press |
| Capacity | 0.5 L (about 17 oz) |
| Body | Borosilicate glass |
| Filter | Filter with silicone rim |
| How it stops the steep | Press plunger |
| Care | Not stated |
| Warranty | Not stated |
Why we recommend it
It suits a big mug drinker, or someone who likes a second small cup from the same brew.
Skip it if you drink only a small cup; this is more than one small serving.
Pros and cons
Pros
- Plunger stops the steep
- See the tea
- Holds more than most here
Cons
- Ships via Amazon’s UK store
- More parts to wash
- Glass can break
How to choose a one cup tea maker
Decide how the steep should stop. Some brewers drop the tea away from the leaves, which ends it cleanly. Presses reduce contact but leave leaves in the pot, so pour off soon after. Basket cups need you to lift the basket. If you tend to walk away, choose one that drains.
Choose the material. Glass lets you watch the color and holds no flavors, but it can break. Stainless steel survives a bag and a commute, but you cannot see into it, and insulated steel keeps tea hot enough to go on steeping. We kept this page to those two because that is what many people look for once they have had enough of plastic. We make no health claim here; it is a preference about taste, looks and durability.
Check the real size. A cup means different things to different makers, and these range from 9 to 17 ounces. Measure your mug if a brewer pours into it.
Look at the filter. Fine leaves like rooibos and broken green tea need fine holes. A fine stainless filter usually keeps them back better than a coarse basket, and a filter you can reach is easier to clean. See our tea infuser guide if you already have a mug you love and only need the basket.
Think about cleaning. Tea leaves are messy. Dishwasher-safe parts help, and tea oils stain, so check how easily you can get a hand or brush inside.
Why the plastic bottom-dispensers are not here
The Adagio IngenuiTEA and the GROSCHE Aberdeen are probably the best-known single-serve brewers. You set them on your mug, and the tea drains from the bottom. Adagio’s listing says BPA free and GROSCHE names Tritan, a plastic, and at 16 and 17.7 ounces they are fine tools. We left them out only because this page is for people who have decided on glass or steel. If plastic does not bother you, they are worth a look, and they are the easiest way to get the draining action.
How we picked these seven tea makers
We looked for small brewers in glass or stainless steel from identifiable makers, holding roughly one mug, with stock on the day. We skipped anything on our other tea pages, including the Kinto one-touch and Rishi glass teapots, and we skipped infuser mugs apart from the one that comes as a brewing kit. We did not brew in these. Our search found no independent review of these exact models, so we rely on listings and say so.
One cup tea maker questions, answered
What is the difference between a tea maker and an infuser mug?
A mug holds a basket that you lift out when you are ready. A tea maker usually handles that step for you, by draining or pressing, and often pours into your own cup.
How much tea should I use for one cup?
Follow the seller of your tea. A common starting point is a rounded teaspoon of loose leaf for 8 ounces of water, and larger leaves take more by volume.
Can I brew tea in a French press meant for coffee?
You can, and the Bodum and FinalPress listings both name tea. Wash them well between uses, since coffee oils can linger and flavor delicate tea.
Is the Bodum recall about these?
CPSC’s October 2026 recall names Bodum 8- and 12-cup French press coffee makers with replaceable glass carafes, in the Bistro, Brazil, Caffettiera, Chambord, Crema, Java, Jesper and Kenya models. The Assam and Travel Press are not named in it. Check the notice if you own a Bodum press.
Do any of these work for iced tea?
FinalPress lists cold brew. For larger batches, see our iced tea maker guide.
Our final pick for a single good cup
The ZENS is the closest match to the idea of one cup, made and separated with a single press, and the Hario is the one for those who just want a small, plain glass pot. For a larger pot to share, try our teapot guide. If it is lunch you are after and not tea, see Julia’s menu and call to order.
