Cà phê sữa đá — literally “coffee, milk, ice” — is the drink most people mean when they say Vietnamese coffee. It looks simple, and it is, but there’s one thing that separates the real thing from a watery imitation: the brew has to be strong enough to survive the ice.
The amounts
These come straight from the calculator’s math at standard strength — condensed milk in the glass first, coffee dripped on top, ice added only after you stir:
| Cup | Coffee | Water | Cond. milk | Ice | Brew time |
|---|---|---|---|---|---|
| 180 ml | 20.5 g | 110 ml | 35 ml | ~65 ml | ~4:00 |
| 240 ml | 27 g | 150 ml | 50 ml | ~85 ml | ~5:10 |
| 350 ml | 39.5 g | 215 ml | 70 ml | ~120 ml | ~7:10 |
Notice the ratio: for an iced glass the coffee is brewed around 1:4 instead of the usual 1:5 for hot phin coffee. About a third of the finished glass is ice, and that ice melts. Brew at hot-coffee strength and by the third sip you’re drinking coffee-flavored water.
The order of operations matters
- Condensed milk goes in the glass first, under the phin. It sits there while the coffee drips on top of it.
- Brew the full 4–6 minutes (the step-by-step guide covers dose, bloom, and drip pace).
- Stir before the ice. Condensed milk is thick; it will not mix itself. Stir until the coffee turns a uniform caramel brown.
- Then pour over a separate glass packed with ice. Pouring the hot mix over ice — rather than dropping ice into the hot glass — chills it fast and keeps the dilution predictable.
Which coffee and which milk?
Robusta, or a robusta-heavy blend. Its bitterness and body are what condensed milk was paired with in the first place — a light arabica disappears under the sweetness. For the milk, any sweetened condensed milk works; in Vietnam it’s usually Longevity or Ông Thọ. Start with the table’s amount and adjust — sweetness is personal, and nobody measures twice.
Too sweet? Meet bạc xỉu’s opposite
If sữa đá is still too much coffee for someone at the table, there’s a drink that flips the ratio — mostly milk, a splash of coffee. That’s bạc xỉu, and it has its own guide.
