VietnamThe coffee matters here more than in most coffee drinks. Vietnamese coffee is traditionally Robusta, which has roughly twice the caffeine of Arabica and a stronger, earthier, more bitter flavor. Arabica brewed at the same strength tastes thin and flat by comparison. If you can find it, Trung Nguyen is the most widely available Vietnamese brand outside Vietnam. Café du Monde, the New Orleans chicory-coffee blend, is a common substitute that works surprisingly well — the chicory adds a roasted depth that approximates the Robusta character. A French roast Arabica is the weakest substitute but still makes a good drink. The condensed milk is non-negotiable — evaporated milk plus sugar is not the same thing. Condensed milk has been cooked down to concentrate both the fat and sugar, which gives it a slightly caramelized quality that plain sweetened milk doesn't have.
No phin? Use a French press: add 2 tablespoons of coarsely ground coffee to the press, pour 120 ml of hot water, wait 4 minutes, press, and pour. Alternatively, pull a double espresso shot and use it directly. The espresso version is faster and the result is very close — the main difference is that the phin brew is slightly less intense per millilitre but the 4 to 6 minute steep time extracts different compounds. Both are good. Keep a tin of condensed milk in the fridge at all times if you make this regularly — it keeps for weeks once opened.
Vietnamese Iced Coffee (Cà Phê Sữa Đá)
By Sergei Martynov
Cà phê sữa đá — coffee, milk, ice — is what happens when French colonial drip culture meets Vietnamese pragmatism. Fresh milk was scarce, so sweetened condensed milk became the standard. Robusta beans, grown abundantly in the Central Highlands, gave the coffee its distinctive strength and slight bitterness. The phin filter slows the brew to a deliberate drip, concentrating the flavor. The result: a drink that is simultaneously very strong and very sweet, poured over ice so the heat of the day doesn't stand a chance. You can replicate it at home without a phin — a strong espresso or French press shot works — but the ritual of watching it drip is worth the five minutes.

How to make it
Instructions
- 1
Set up the phin. Rinse the phin filter with hot water first — this preheats the metal and helps the coffee bloom and drip more evenly. Spoon the ground coffee into the phin chamber. Tap it gently to level the grounds, then place the press plate on top. The press sits on the grounds under its own weight and regulates flow — don't screw it down tightly, which would slow the drip to a trickle, but don't leave it loose, which would make it too fast.
- 2
Add the condensed milk. Spoon the sweetened condensed milk into a heat-proof glass or cup. The coffee will brew directly on top of it. This is the traditional order: milk first, coffee second, so that when you pour over ice the layers are visible briefly before you stir. How much condensed milk is personal — two tablespoons is a starting point; Vietnamese street coffee is often much sweeter.
- 3
Bloom and brew. Place the assembled phin on top of the glass with the condensed milk. Pour a small amount of hot water — about 2 tablespoons — over the grounds and wait 30 seconds. This is the bloom: the coffee degasses and the grounds absorb the water, which improves extraction. Then pour the remaining water slowly to fill the chamber. Put the lid on. The coffee will begin to drip. A well-set phin drips at roughly one drop per second — the full brew takes 4 to 6 minutes. If it drips faster the press is too loose; slower, slightly too tight.

Stir and pour over ice. Once the dripping stops, lift the phin off the glass. Stir the coffee and condensed milk together vigorously until fully combined — the condensed milk is thick and settles at the bottom, so stir properly. Fill a tall glass with ice. Pour the hot coffee mixture over the ice. It will cool immediately on contact. Stir once more.
- 5
Serve and drink immediately. Vietnamese iced coffee is meant to be drunk cold and without delay — the ice dilutes it slightly as it melts, which is part of the balance. A glass of plain cold water alongside is traditional. If you want to try the hot version (cà phê sữa nóng), skip the ice and drink directly from the brew glass, or warm the whole glass briefly in a bowl of hot water before serving.
Frequently Asked Questions
What makes Vietnamese coffee different from other iced coffees?
Three things distinguish it: the bean, the brew method, and the sweetener. Vietnamese coffee uses Robusta beans, which are stronger and more bitter than the Arabica beans used in most Western coffee. The phin filter produces a slow drip concentrate — not espresso, not filter coffee, something between the two in body and intensity. And sweetened condensed milk replaces fresh milk and sugar, adding a rich, slightly caramelized sweetness that fresh dairy doesn't produce. The combination of very strong, slightly bitter coffee with very sweet, thick condensed milk is the point — neither element works as well on its own.
What is a phin filter and do I need one?
A phin is a small, stainless steel single-serve drip filter — a chamber that holds the grounds, a press plate that sits on top of them, and a lid. It sits directly on top of your cup and the coffee drips through under gravity, taking 4 to 6 minutes for a full brew. Phins cost around £5 to £10, are widely available online, and last indefinitely. You don't need one — a French press or espresso machine works — but the phin produces a specific brew character that's slightly different from both. It's also compact, requires no electricity, and produces no waste beyond the grounds.
Can I make this without condensed milk?
Technically yes, but the result won't be Vietnamese coffee — it'll be strong iced coffee with milk and sugar. Condensed milk is partially caramelized through the canning process, which gives it a distinctive flavor that doesn't come from simply mixing evaporated milk with sugar. If you want to reduce sweetness, use less condensed milk rather than substituting it. One tablespoon instead of two gives a less sweet but still genuine version. Coconut condensed milk is an available and good dairy-free alternative — it's richer than regular coconut milk and works particularly well.
What coffee should I use if I can't find Vietnamese brands?
In order of preference: Trung Nguyen (the standard, available in most Asian supermarkets and online), Café du Monde (New Orleans chicory blend, widely available, excellent substitute), any dark or French roast Robusta or Robusta blend, and finally a dark roast Arabica. The key is that the coffee must be strong enough to hold its own against the condensed milk — a medium roast Arabica will taste washed out and thin. Whatever you use, grind it coarsely if using a phin, or use an espresso grind if pulling a shot.
What other Vietnamese coffee variations are there?
Cà phê sữa nóng is the hot version — the same drink without the ice, usually kept warm in a small glass sitting in a bowl of hot water. Cà phê đen đá is black iced coffee — no condensed milk, just strong coffee over ice. Cà phê trứng (egg coffee) is Hanoi's famous variant: coffee topped with a thick, sweetened whipped egg yolk foam — the texture is similar to a coffee dessert. Cà phê cốt dừa (coconut coffee) layers coffee with coconut milk and condensed milk. All of these start with the same strong phin-brewed coffee base.
