How to Make Vietnamese Iced Coffee with Condensed Milk

When summer heat hits, nothing beats the slow, sweet chill of a well-made Vietnamese iced coffee. But if you’ve only ever had syrupy, instant versions, you’re missing out on the real deal: a slow-dripped, bold espresso cut with creamy condensed milk and served over crushed ice. That’s the version that’s been cooling off Vietnamese coffee drinkers for decades—one careful drop at a time.

To make traditional Vietnamese iced coffee the authentic way, you’ll need 4 teaspoons of condensed milk, 4 teaspoons of medium-ground coffee (about 12g), hot water between 96–100°C, and plenty of large ice cubes. The full process takes around 7 minutes from start to sip.

What Makes Vietnamese Iced Coffee Different?

Vietnamese iced coffee stands apart thanks to its unique brewing method and bold flavor balance. Unlike filtered or espresso-based iced coffees, it’s made using a small metal drip filter called a phin. This tool slowly drips a strong, dark brew directly over sweetened condensed milk in a glass. The coffee is brewed hot, then poured over ice—letting the temperature contrast amplify aroma and sweetness. It’s creamy, intense, and built for slow sipping.

Why Use a Drip Filter? The Role of the Phin

The heart of Vietnamese iced coffee is the phin—a small metal single-serve dripper that works entirely by gravity. There’s no paper filter, pump, or electricity involved. Instead, ground coffee is tamped down under a screw-down filter plate. The tighter you screw it, the slower the drip. That control lets you fine-tune extraction for a brew that’s neither too weak nor overly bitter. The metal construction also lightly infuses the coffee with iron notes over time, adding subtle complexity.

How to Make Vietnamese Iced Coffee: Step-by-Step

Here’s the classic method used in Vietnam, broken down for clarity:

• Step 1: Pour 4 teaspoons (about 2 tablespoons) of sweetened condensed milk into a tall glass. Set aside.
• Step 2: Add 4 teaspoons (around 12g) of medium-ground coffee to the phin. Shake gently to level the grounds.
• Step 3: Screw the filter press down firmly—but adjust based on your preferred drip speed. A tighter press slows extraction.
• Step 4: Place the phin directly over the glass with condensed milk. Add a small amount of 96–100°C hot water (just enough to wet the grounds), and wait about 30 seconds for the coffee to bloom.
• Step 5: Fill the phin to about 50–60% full with more hot water. Secure the lid. In ideal conditions, the coffee will drip at a rate of 65 drops per minute, finishing in roughly 5–6 minutes. If it drips too fast or slow, check your grind, water temp, or how tightly the press is screwed.
• Step 6: Once brewing is complete, add a generous amount of large ice cubes to the glass. Stir gently until the condensed milk, coffee, and ice are fully mixed. Serve immediately.

What Ice Should You Use?

Don’t skimp on ice. The recipe specifically calls for “big, plentiful ice cubes.” That’s because the coffee is initially hot, and the contrast between hot brew and cold ice is essential to unlocking the full aroma. Small or melted ice will water down your drink too quickly and dull the flavors. Use freshly frozen cubes, and add enough to fill at least half the glass.

Flavor Profile & Customization

The result is a thick, sweet, and intensely caffeinated iced coffee. The condensed milk balances the bitter edge of the dark roast, while the slow drip preserves the coffee’s body and complexity. If you prefer it less sweet, reduce the condensed milk. For a stronger kick, increase the coffee dose slightly or use a finer grind (but expect a faster drip time).

Frequently Asked Questions

Can I use any type of coffee for Vietnamese iced coffee?

Traditional Vietnamese iced coffee is typically made with a dark roasted robusta or dark robusta-arabica blend, which gives it a bold, bitter edge that pairs well with condensed milk. However, you can experiment with medium or dark roasted arabica if you prefer a smoother, less intense flavor. Just avoid very light roasts, as they lack the body needed for this style.

Do I have to use condensed milk?

Condensed milk is essential for authentic Vietnamese iced coffee. Its thick, sweet profile is what gives the drink its characteristic creaminess and balances the strong brewed coffee. Substituting with regular milk and sugar will change the flavor and texture significantly. If you must avoid condensed milk, try a very thick sweetened plant-based alternative, but it won’t be the same.

How important is the drip speed?

Very. A proper Vietnamese iced coffee should drip at around 65 drops per minute and take roughly 5–6 minutes total. If it drips too quickly, your coffee will be under-extracted and sour; if too slow, it may over-extract and taste bitter. Adjust the tightness of the filter press to manage the speed.

Can I make this without a phin?

You can try alternatives like a pour-over with a very fine drip or a small espresso shot, but the unique flavor and slow extraction achieved with a traditional phin are hard to replicate exactly. The phin’s design controls brew time and concentration precisely in a way other methods can’t.

Why does the ice need to be big and plentiful?

Large ice cubes melt slower, keeping your coffee colder for longer without overly diluting it. Since the coffee is brewed hot and then poured over ice, rapid melting can ruin the balance of flavors. Plenty of ice ensures the drink stays chilled and refreshing from the first to the last sip.
