Tom Yum Coffee: What It Is, How It Tastes & Where to Try It
By the Thongyib Thongyod team · Updated 12 July 2026
Tom yum coffee is exactly what the name threatens: a coffee that borrows its soul from Thailand’s most famous soup. Ours is an iced espresso built with ginger, lemongrass, bergamot, chili and lime, lifted with soda — every aromatic from a proper tom yum, minus the broth, the shrimp and the fish sauce. It sounds like a dare. It drinks like a discovery. And because it’s the drink guests mention most in our reviews, this page is the full story from the people who actually pour it.
In short:
- Tom yum coffee = espresso + the herbs of tom yum soup: ginger, lemongrass, bergamot, chili, lime — over soda and ice
- No broth, no shrimp, no fish sauce; it borrows the soup’s aromatics, not its stock
- Tastes like a bright sparkling espresso with a citrus-herb edge, not like soup
- 99฿ at Thongyib Thongyod in Ao Nang, one of eleven house signature coffees
- Vegetarian, iced, and photographed roughly as often as it’s ordered
We run Thongyib Thongyod, a brunch cafe and specialty-coffee shop near Nopparat Thara Beach in Ao Nang, and “the tom yum coffee — is that serious?” is a counter conversation we have most days of high season. It is serious. Here’s what’s in the glass, why it exists, and how to decide whether it’s your kind of strange.
What is tom yum coffee?
Start with the soup. Tom yum is Thailand’s hot-and-sour signature — a broth whipped into fragrance by lemongrass, galangal or ginger, kaffir lime, chili and a squeeze of lime juice. Strip away the stock and the seafood, and what’s left is a perfume: citrus, warmth, a green herbal snap. That perfume is the whole idea.
Tom yum coffee takes those aromatics and rebuilds them around espresso. In our version, a shot of espresso meets ginger, lemongrass, bergamot and lime, gets lengthened with soda, and arrives iced, garnished the way the soup would be — lemongrass stalk, kaffir lime leaf, one glossy red chili lying across the top like a warning label it doesn’t really need. The chili is theatre more than fire; nobody has ever needed a glass of milk afterwards.
If you know the modern espresso-tonic family of drinks, you already know this drink’s cousins. Coffee and citrus are old friends — that’s the entire logic of our Yuzu Coffee and the lemon-mint Secret N.9 — and coffee with herbs is barely more radical. Tom yum coffee just sources its herbs from the most Thai place imaginable.
Does it actually taste like soup?
No — and this is the answer that unlocks the order for most hesitant people. Close your eyes and you’re drinking a sparkling, citrus-forward iced espresso: the lime and bergamot arrive first, the lemongrass gives it that unmistakably Thai green freshness, the ginger warms the back of the sip, and the espresso holds the middle so it never turns into a soft drink. What you will not taste is broth. There’s no fish sauce, no shrimp, no savoury anything. The soup lends its herbs and keeps its stock.
One of our guests put it better than we ever have, in a Google review we’ve quoted ever since: “I had the tom yam coffee (cold brew) that was such a unique flavor!” Unique is the fair word. It isn’t a crowd-pleaser in the way our caramel-popcorn Popular Coffee is a crowd-pleaser — it’s the one you order because you’re in Thailand, the sun is out, and a coffee that tastes faintly of lemongrass suddenly makes perfect sense in a way it never would at home.
Who should order it: anyone who likes espresso tonics, sours, yuzu anything, or simply a story. Who should maybe start elsewhere: if your coffee ceiling is a smooth latte, ease in with the Coco Flower — espresso with coconut-flower juice — and work your way up to the soup aisle.
Curious enough to taste it? We pour tom yum coffee daily from 8:00 to 18:00, five minutes from Nopparat Thara Beach. See the coffee menu · Get directions
How did a soup end up in an espresso?
Because we had time, and stubbornness, and a bar to ourselves. Thongyib Thongyod opened in 2020 — twin sisters from Isan, launching a tiny cafe into the least hospitable year in tourism history. The silver lining of empty seasons was empty afternoons, and the signature-coffee board became the project: What flavours are ours? What would a coffee that could only come from Thailand taste like?
Some experiments earned their menu spot politely — yuzu and espresso were always going to get along. Tom yum was the audacious one, and it went through the most rounds: getting the lemongrass to read as fragrance instead of potpourri, letting bergamot bridge the citrus and the coffee, keeping the chili decorative. When guests started photographing it before drinking it, then telling the next table what it was, we knew it had stopped being an experiment.
It’s been the most-talked-about pour on the board ever since — the drink reviews name-check, the one that gets ordered “for the table” alongside safer coffees. For the traditional side of Thai coffee culture (the sock-filtered oliang your grandfather would recognise), we wrote a separate guide to Thai iced coffee; tom yum coffee is what happened when that heritage got a modern espresso machine and a sense of humour.
What else is on the signature board?
Tom yum coffee has ten siblings, all at 99฿, all built on the same principle: espresso plus one genuinely Thai or genuinely playful idea. The full lineup lives on the coffee page, but here’s the family portrait:
| Signature | What it is | Order it if |
|---|---|---|
| Tomyum Coffee | Espresso, ginger, lemongrass, bergamot, soda, chili & lime | You want the story and the bright, herbal sparkle |
| Popular Coffee | Espresso, milk, caramel & popcorn | You want the crowd-pleaser — it’s our most-ordered coffee |
| Yuzu Coffee | Espresso with yuzu jam & soda | You like citrus doing the heavy lifting |
| Secret N.9 | Espresso, lemon, mint, raw sugar & soda | You want refreshing with a riddle of a name |
| Coco Flower | Espresso with coconut-flower juice | You want gentle, tropical and a little elegant |
| O-No Coffee | Espresso with fresh orange juice | You’ve always wondered (it works) |
| Dirty Coffee / Dirty Bloom | Double ristretto over cold milk (Bloom adds Milo) | You take coffee seriously but not solemnly |
| Sweet & Sour | Espresso, lime, mint & raw sugar | You want Secret N.9’s straightforward cousin |
| Berry Land / Rose Valley | Espresso with mixed-berry juice / rose syrup | You drink with your camera first |
Where can you try tom yum coffee?
At our counter, most easily. Thongyib Thongyod Brunch & Cafe sits inside Ao Nang Landmark (the Sealay Village side) in Khlong Haeng — a five-minute walk from Nopparat Thara Beach, a few minutes’ drive from Ao Nang Beach, open every day from 8:00 to 18:00, no bookings needed. The drink is 99฿, iced, vegetarian like the rest of the board, and takes about as long to make as it takes to find a seat by the water table and the fish pond.
The sensible pairing advice, since you’ll ask: it’s a bright, sharp drink, so it loves rich food — banana pancakes, a chocolate croffle, or the golden Thai desserts we’re named after. And if the person across the table wants nothing to do with chili on a coffee, the full menu runs to 151 dishes and drinks, including plenty of much tamer choices; everyone leaves happy, one of you leaves with a better story.
One last honest note: we didn’t patent the idea of putting Thai herbs in coffee, and we wouldn’t want to — Thailand’s cafe scene is inventive from Chiang Mai to the deep south. But if you’re in Krabi and the phrase “tom yum coffee” has been rattling around your head since you read it, this is where the glass with the chili on top is waiting.
