How to Make Authentic Vietnamese Iced Coffee

If you’ve ever craved a coffee that’s thick, sweet, and refreshingly cool all at once, you’ve likely heard of Vietnamese iced coffee — the kind that drips slowly into a glass of ice, layered with creamy condensed milk. But making it right at home? That means getting the drip just right, balancing sweetness, strength, and chill. Here’s exactly how the Vietnamese do it, step by step.

To make authentic Vietnamese iced coffee, use 4 teaspoons (about 12g) of medium-ground coffee, 3–4 teaspoons of condensed milk, and brew through a Vietnamese drip filter with 96–100°C water. The entire process takes around 7 minutes, and the coffee should drip at roughly 65 drops per minute for ideal balance.

What Makes Vietnamese Iced Coffee Different?

Vietnamese iced coffee stands out because it’s brewed strong, sweetened with sweetened condensed milk, and served over ice — but the real magic is in how it’s brewed. Unlike espresso or French press, it uses a small metal drip filter called a phin. This slow, controlled drip extracts bold flavours and lets you adjust strength and speed by tightening or loosening the filter’s press.

Why the Drip Speed Matters

The speed at which your Vietnamese coffee drips directly affects taste. Too fast, and the coffee will be weak and under-extracted; too slow, and it becomes overly bitter or cold before it’s done. The ideal drip rate is about 65 drops per minute, and the whole brew should finish in around 5–6 minutes. That pace ensures balanced extraction and allows the hot coffee to interact with the ice properly later for full flavour.

What You’ll Need

• Medium-ground coffee (about 12g or 4 tsp) — avoid too fine a grind to prevent clogging
• Vietnamese coffee drip filter (phin)
• 3–4 teaspoons of sweetened condensed milk (adjust to taste)
• Plenty of large ice cubes
• Hot water between 96–100°C

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

1. Prep the Glass: Pour 3–4 teaspoons of condensed milk into your serving glass and set aside.
2. Measure the Coffee: Add 4 teaspoons (around 12g) of medium-ground coffee into the phin. Shake gently to level the grounds.
3. Set the Drip Rate: Screw the filter press down. The tighter it is, the slower the drip — adjust based on your preferred strength and brew time.
4. Bloom the Coffee: Place the phin on the glass, pour a small amount of 96–100°C hot water to wet the grounds. Let it bloom for about 30 seconds — this helps extraction.
5. Brew the Coffee: Fill the phin with 50–60% hot water, then top up after a moment. Keep the water level about ⅝ full. The coffee should now begin dripping steadily. Total brew time should be around 5–6 minutes at ~65 drops per minute.
6. Serve Over Ice: Once brewing finishes, add a generous amount of large ice cubes to the glass, stir everything together until fully combined, and enjoy.

Common Mistakes to Avoid

• Using water that’s not hot enough (below 96°C) — it leads to under-extraction and weak flavour.
• Grinding coffee too finely — it can clog the phin and drastically slow the drip or over-extract.
• Not letting the coffee bloom — skipping this step reduces aroma and clarity.
• Rushing the drip by loosening the press too much — results in thin, sour coffee.
• Using small or melted ice — large, solid cubes keep the drink cold without diluting it too fast.

Why Vietnamese Coffee Uses Condensed Milk

Vietnamese iced coffee traditionally uses sweetened condensed milk instead of fresh milk or cream. This is partly due to historical access to preserved ingredients, but also because condensed milk’s thick, caramelly sweetness balances the intense, bold brew from the dark-roasted coffee. It creates a rich, dessert-like drink that’s both cooling and indulgent.

How to Adjust Strength and Sweetness

The beauty of the Vietnamese drip method is control. To make it stronger, use more coffee or tighten the press. For a sweeter drink, add more condensed milk. For a lighter version, reduce either — or serve the brewed coffee black over ice and add milk separately.

Frequently Asked Questions

What is the ideal drip rate for Vietnamese iced coffee?

The ideal drip rate is around 65 drops per minute, with the total brew time taking approximately 5–6 minutes. This ensures proper extraction and flavour balance. If it drips too fast, the coffee may taste weak; too slow, and it risks becoming bitter or overly concentrated.

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

Traditionally, Vietnamese iced coffee is made with a dark-roasted coffee, often a robusta-blend for boldness. However, you can experiment with different roasts. Just make sure to use medium grind to avoid clogging the phin filter and to maintain proper drip speed.

How much condensed milk should I use?

The standard amount is 3–4 teaspoons, but you can adjust to your taste. Start with 3 teaspoons for a balanced sweetness, then add more if desired. The condensed milk is key to the drink’s signature creamy, sweet profile.

Why is my Vietnamese coffee dripping too fast or too slow?

Drip speed is controlled by how tightly you screw down the press on the phin. A tighter press slows the drip, while a looser one speeds it up. Adjust the tightness to aim for around 65 drops per minute and a total brew time of 5–6 minutes.

Do I have to use ice cubes? Can I use crushed ice?

Large ice cubes are ideal because they melt slowly, keeping your drink cold without diluting it too quickly. Crushed ice melts faster and can water down the coffee’s flavour, so it’s better to avoid it if possible.

Can I make Vietnamese iced coffee without a phin?

While a phin is traditional and gives you control over drip speed, you can try alternatives like a pour-over with a slow pour or even cold brew methods. However, these won’t replicate the same slow-dripped, bold intensity of the original phin-brewed version.
