How to Make Vietnamese Salt Coffee (Cà Phê Muối) From Huế
Share
Salt in coffee sounds like a mistake until you try a cup of cà phê muối. In this Vietnamese drink from the old imperial city of Huế, strong, dark coffee is poured over sweetened condensed milk and topped with a thick, lightly salted cream. The salt does not make it taste salty; it makes it taste rounder, sweeter and somehow more like caramel. If you want to know how to make Vietnamese salt coffee at home, you need four things: strong coffee, condensed milk, heavy cream and a pinch of salt. A Vietnamese phin filter helps, but it is not essential.
Below: the real origin story, the recipe in hot and iced versions, the best coffee to use and the mistakes that turn it into seawater.
Key takeaways
- Cà phê muối is generally credited to a small Huế café run by a couple in the early 2010s.
- It is made of three layers: condensed milk, strong phin coffee and salted cream foam.
- Use only a pinch of salt: the goal is a salted-caramel effect, not a salty drink.
- Dark, bold coffee works best; Robusta or a Robusta blend is the classic Vietnamese choice.

Where Vietnamese salt coffee comes from
Like many famous drinks, salt coffee has a tidy legend and a messier history. Popular folk tales tell of a newlywed who mixed up the sugar and the salt, or a nervous suitor who drank a salty coffee on a first date out of politeness. They are charming, and almost certainly invented.
The origin generally accepted today is more practical. Around the early 2010s, a couple in Huế, Trần Nguyễn Hữu Phong and Hồ Thị Thanh Hương, created the drink to draw customers to their small coffee shop, which they named Cà Phê Muối, simply “salt coffee”. They never protected the idea, and they have kept their exact recipe to themselves.
The drink spread quickly through Huế cafés and then along the central coast to Đà Nẵng and Hội An. It is now a staple of Vietnam’s south central coast and has won fans in Hanoi too. If you are new to Vietnamese coffee, our guide to Vietnamese coffee covers the phin, Robusta and condensed milk basics.
Why salt works in coffee
A small amount of salt changes how we perceive bitterness and sweetness: the coffee tastes less harsh and the condensed milk tastes more rounded. That is the same effect that makes salted caramel taste better than plain caramel. We explain the science and the right amounts in our article on salt in coffee, so here we will focus on the drink itself.
In cà phê muối, the salt goes into the cream, not the coffee. That matters: the first sips hit the salted foam, then the bold coffee, then the sweet condensed milk as you stir. Each sip shifts slightly, which is a big part of its appeal.
How to make Vietnamese salt coffee
Ingredients (1 serving)
| Ingredient | US | Metric |
|---|---|---|
| Dark-roast ground coffee (medium-fine) | 2 tbsp, heaped | 18–20 g |
| Hot water, just off the boil | 3–4 oz | 90–120 ml |
| Sweetened condensed milk (for the cup) | 1–2 tbsp | 20–40 g |
| Heavy cream (for the foam) | ¼ cup | 60 ml |
| Sweetened condensed milk (for the foam) | 1 tbsp | 20 g |
| Fine sea salt | 1 small pinch (about ⅛ tsp) | about 0.5 g |
Steps
- Brew the coffee. Put the coffee in a phin filter set over your cup or glass. Pour in about 1 oz (30 ml) of hot water to bloom it for 30 seconds, then fill the chamber and put the lid on. It should drip slowly, in about 4–5 minutes. No phin? Use a moka pot or a double shot of espresso plus 1 oz of hot water.
- Add condensed milk to the cup. If you are not brewing directly over it, spoon the condensed milk into the bottom of a small heatproof glass and pour the coffee over it.
- Make the salted cream. In a small bowl or jar, combine the cream, 1 tablespoon of condensed milk and the salt. Whisk or froth until it thickens to soft, pourable peaks, like melted ice cream. About 30 seconds with a handheld frother, or 1–2 minutes by hand.
- Taste the foam. It should taste sweet first, with a gentle salty finish. Too salty? Add a spoon of cream and whisk again.
- Layer. Spoon the salted cream gently over the coffee so it floats on top.
- Drink it the Huế way. Sip the layers first, then stir everything together for the rest of the cup.
Iced, lighter and dairy-free versions
Iced salt coffee
Brew the coffee over the condensed milk, stir, then pour over a glass full of ice. Top with the salted cream. Make the foam slightly thicker than for the hot version so it sits on the ice. For more on Vietnamese iced coffee style, see Vietnamese iced coffee.
Lighter version
Replace the heavy cream with whole milk and froth it with a handheld frother. Use 1 teaspoon of condensed milk in the foam and skip it in the cup. It will be less rich, but still has the salty-sweet contrast.
Dairy-free
Use condensed coconut milk instead of condensed milk, and whip chilled full-fat coconut cream with the salt for the foam. The coconut adds a tropical note that suits dark coffee.
Which coffee to use
Vietnamese coffee culture is built on Robusta: bold, low in acidity, with a heavy body and more caffeine than Arabica. It stands up to both condensed milk and salted cream, where a light, fruity Arabica would disappear. Feel Espresso’s Robusta from West Java, Indonesia, has cacao, Brazil nut and malt notes and plenty of body, which makes it a natural fit. If you prefer a classic dark roast, Italian Roast blends Arabica and Robusta for an intense, smoky cup, and French Roast gives a bold, bittersweet chocolate base with low acidity. Order it ground for Espresso if you use a phin or moka pot.
Common mistakes
| Mistake | What happens | Fix |
|---|---|---|
| Too much salt | Tastes like seawater | Start with a tiny pinch; you can always add more |
| Salt stirred into the coffee | Flat, oddly savory drink | Put the salt in the cream foam |
| Weak or light-roast coffee | Cream and sugar overpower it | Use a dark roast and a strong ratio |
| Over-whipped cream | Stiff blob that will not blend | Stop at soft, pourable peaks |
| Coarse salt flakes in the foam | Salty bursts | Use fine sea salt so it dissolves |
Vietnamese salt coffee FAQ
What does salt coffee taste like?
Like a strong, sweet iced coffee with a salted-caramel edge. The salt is subtle; it softens bitterness and makes the cream taste richer.
Is salt coffee the same as egg coffee?
No. Egg coffee, from Hanoi, uses whipped egg yolk with sugar and condensed milk. Salt coffee uses salted cream. See our Vietnamese egg coffee recipe for the other classic.
Can I make salt coffee without a phin?
Yes. Espresso or moka pot coffee works well. Avoid weak drip coffee, which gets lost under the cream.
Is salt coffee served hot or cold?
Both. In Vietnam it is commonly ordered either way; the iced version is especially popular in hot weather.
Who invented salt coffee?
It is generally credited to Trần Nguyễn Hữu Phong and Hồ Thị Thanh Hương, who served it at their Huế café, Cà Phê Muối, in the early 2010s. Stories about accidental salty coffee are folk tales.
