The phin is a small metal filter that sits on top of the cup and drips dark, concentrated coffee through a perforated press. It belongs to Vietnam's café culture, where the coffee falls onto a spoonful of sweetened condensed milk and takes four or five minutes to finish. Stirred and poured over a tall glass of ice, it becomes cà phê sữa đá; drunk hot, it is cà phê sữa nóng. Dark-roast robusta gives the bitterness the sweet milk needs, which is why the drink works at all.
Steps
Spoon condensed milk into the cup
The milk goes in first and the coffee drips onto it, so the two meet in the cup and only need a stir at the end.
Set the coffee in the phin and press it down
The press holds the grounds in a flat bed so the water passes evenly; a level, snug press is what turns a drip into a steady one.
Pour a little water and let it bloom for about 30 seconds
A small first pour swells the grounds and lets them release gas; the phin then settles into an even flow rather than stalling halfway through.
Fill with the rest of the water and let it drip
The slow drip takes four or five minutes, and that contact time is what builds a concentrate strong enough to stand up to the sweet milk.
Stir well and serve hot, or pour over a tall glass of ice
The milk stays at the bottom until you stir. Mixing it in fully before adding ice keeps the drink even from the first sip to the last.

Tips
- Be patient — the drip takes 4–5 minutes, and rushing it shortchanges the extraction.
- For the iced version, brew a little stronger — the melting ice dilutes the glass, so a slightly larger dose or a little less water keeps it from going thin.
Common mistakes
- Pushing the press down hard or fast — it channels the water through gaps in the grounds and the drip turns erratic.
- Stirring during the drip — it dislodges the bed and the flow collapses, stalling or flooding the extraction.
Variations
Within the Vietnamese tradition, the preparation above takes these familiar shapes:
Indonesian Kopi Susu
The family resemblance is real — robusta and sweetened condensed milk — but phin coffee drips clean through a metal filter for a more concentrated cup, while kopi susu is tubruk-style, steeped with the grounds left right in the glass.
Vietnamese Bạc Xỉu
The milk-forward glass bạc xỉu inverts this recipe's balance: the same phin and condensed milk, with the milk rather than the coffee taking most of the glass.
FAQ
Why is condensed milk used in Vietnamese coffee?
Because fresh milk was scarce and spoiled quickly in the tropical heat. When the French brought coffee to Vietnam, sweetened condensed milk, which keeps without refrigeration, took its place. Its sweetness also balances the bitterness of dark-roast robusta.
How strong is Vietnamese phin coffee?
Strong. Vietnamese recipes put roughly 20–25 g of coffee through 100–200 ml of water, about 1:4 to 1:10, much denser than a typical drip brew. It is usually robusta, which carries close to twice the caffeine of arabica, so it is paired with condensed milk and often ice.
