The short answer
Vietnamese iced coffee uses a small metal phin filter to drip dark-roast coffee directly over 2–3 tablespoons of sweetened condensed milk, then it’s poured over a tall glass of ice. Brew time is about 4–5 minutes. Total hands-on effort: under 2 minutes.
The result is intensely sweet, creamy, and strong — the condensed milk balances the bold, sometimes slightly bitter dark roast that’s traditional in Vietnam. It’s arguably the world’s easiest iced coffee.
What you need
• A phin filter — a small stainless-steel dripper that sits on top of your glass. Available for $5–10 online.
• 2–3 tablespoons (14–20 g) of dark-roast coffee, ground medium to medium-coarse. Café Du Monde (with chicory) is the classic brand, but any bold dark roast works. For roast guidance, see light vs dark roast.
• 2–3 tablespoons of sweetened condensed milk (adjust to taste).
• ≈100 ml (3.4 oz) of hot water just off the boil (200–205 °F).
• A tall glass filled with ice.
Step-by-step recipe
1. Add 2–3 tablespoons of sweetened condensed milk to the bottom of a heatproof glass.
2. Place the phin filter on top of the glass. Add 2–3 tablespoons (14–20 g) of ground coffee to the chamber.
3. Place the press screen on top of the grounds and turn it clockwise until snug — firm but not cranked down. This controls drip speed.
4. Pour a small splash of hot water (≈20 ml) over the press screen to bloom the grounds. Wait 20–30 seconds.
5. Fill the chamber with the remaining hot water (≈80 ml). Place the cap on top to retain heat.
6. Let it drip. The brew should finish in 4–5 minutes. If it drips faster than 3 minutes, tighten the press screen or grind finer next time. If slower than 6 minutes, loosen it or grind coarser.
7. Remove the phin, stir the coffee and condensed milk together, then pour the mixture over a tall glass of ice. Stir and drink.
Variations worth trying
• Hot version (ca phe sua nong): skip the ice and drink it warm. The condensed milk dissolves more easily and the flavor is rounder.
• Black iced (ca phe den da): drop the condensed milk entirely for a bold, unsweetened iced coffee. Add a teaspoon of sugar if you want light sweetness without the cream.
• Coconut milk swap: replace condensed milk with 2 tablespoons of coconut cream + 1 teaspoon of sugar for a dairy-free version with tropical undertones.
• Egg coffee (ca phe trung): whip an egg yolk with condensed milk until fluffy and spoon it on top of hot black coffee — a Hanoi specialty that tastes like liquid tiramisu.
Each variation uses the same phin brew as the base. Once you own the filter, the possibilities expand quickly.
Tips for dialing it in
• Grind size matters. The phin has no paper filter, so too-fine grounds slip through and make the cup gritty. Start with a medium-coarse grind (slightly coarser than drip) and adjust. Our grind size chart has a visual reference.
• Condensed milk brand matters less than amount. Most brands (Longevity, Eagle Brand) taste similar. Start with 2 tablespoons and adjust next time.
• Brew a double. If you want a bigger drink, brew two phin rounds into the same glass or buy a larger 8 oz phin filter.
