How to Make Vietnamese Iced Coffee with Condensed Milk

If you’ve ever craved a strong, sweet, and refreshingly cold coffee on a hot day, you’ve likely heard of Vietnamese iced coffee. But making it the traditional way—with slow drips through a metal phin filter, layered with creamy condensed milk and served over ice—isn’t as simple as tossing grounds into a cup. Here’s how to get that velvety texture and bold flavor the Vietnamese way.

The entire process takes just seven minutes—but the secret is in the details: 12 grams of medium-ground coffee, 3–4 teaspoons of sweetened condensed milk, hot water between 96°C–100°C, and ice added only after brewing. Done right, it’s rich, smooth, and perfectly balanced.

What Makes Vietnamese Iced Coffee Different?

Vietnamese iced coffee stands out due to its use of sweetened condensed milk and a slow-dripping phin filter. Unlike espresso-based iced drinks or quick cold brews, this method relies on hot water extracting flavor through a fine metal filter—then cooling instantly with ice. The result? A thick, dessert-like coffee with deep roasted notes and creamy sweetness.

Key Ingredients for Authentic Vietnamese Iced Coffee

To brew Vietnamese iced coffee the traditional way, you’ll need:

• Medium-ground coffee: Avoid too fine or too coarse—a medium grind (around standard drip or slightly finer) prevents excessive sludge and ensures proper flow.
• Phin filter (drip filter): The iconic small metal filter that slowly drips brewed coffee drop by drop.
• Sweetened condensed milk: Around 3–4 teaspoons (adjust to taste).
• Ice cubes: Use large, plentiful cubes to keep the drink cold without diluting it too fast.
• Hot water: Between 96°C and 100°C (just off boil).

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

Here’s the precise, traditional method used in Vietnam every day:

1. Start with condensed milk: Add 3–4 teaspoons of sweetened condensed milk to the bottom of your serving glass. Adjust amount to your preferred level of sweetness.
2. Add coffee to the phin: Place 4 teaspoons (approximately 12 grams) of medium-ground coffee into the phin filter. Shake gently to level the bed.
3. Adjust the brewing speed: Screw down the press plate firmly. The tighter it is, the slower the brew—control drip speed by adjusting pressure.
4. Bloom the coffee: Place the phin on your glass, pour in a small amount of 96°C–100°C hot water (just enough to wet the grounds), and wait 30 seconds for the coffee to bloom and begin dripping.
5. Complete the brew: Add more hot water until the phin is about 50–60% full. Put the lid on and let it drip. Ideal speed is around 65 drops per minute, taking roughly 5–6 minutes for a full brew. Too fast means under-extracted and weak; too slow leads to bitterness or cooling too soon.
6. Assemble and serve: Once brewing finishes, add plenty of ice cubes to the glass, stir well to combine the condensed milk, brewed coffee, and ice. Serve immediately.

Why Timing and Temperature Matter

The 5–6 minute brew time isn’t arbitrary. That slow drip extracts the coffee’s body and sweetness while balancing the intensity. The near-boiling water (96°C–100°C) ensures proper extraction from the medium grind, and pouring over ice at the end creates that signature contrast of hot extraction and cold refreshment.

Frequently Asked Questions

What kind of coffee grind should I use for Vietnamese iced coffee?

Use a medium grind—similar to table salt or slightly finer. It should be finer than what you’d use for French press but not as fine as espresso. This ensures proper flow through the phin filter without clogging or over-extracting.

Can I use regular milk instead of condensed milk?

Traditionally, Vietnamese iced coffee uses sweetened condensed milk for its thick, caramelized sweetness. Substituting with regular milk and sugar won’t replicate the same creamy texture or balance of flavors, though it can be done if desired.

How tight should the phin filter’s press plate be?

Tighten the press plate firmly—the tighter it is, the slower the coffee drips. Adjust based on your preferred brew time. A slower drip (around 65 drops/minute) typically produces a richer cup, but if it’s too slow, the coffee may over-extract or get too cold.

Do I need to preheat the phin or glass?

The original method doesn’t require preheating, but doing so could help maintain brew temperature during the initial bloom. However, the coffee is designed to drip over ice, so rapid cooling is part of the intended experience.

Why does my Vietnamese iced coffee taste bitter or weak?

Bitterness often results from over-extraction (too fine a grind, too slow a drip, or overly long brew time). Weak or sour coffee usually means under-extraction (too coarse a grind, too fast a drip, or insufficient bloom). Adjust grind size and drip speed accordingly.

Can I make Vietnamese iced coffee without a phin?

Technically, you can try using other drip methods, but the unique slow extraction and pressure control of the phin filter are key to the traditional flavor and texture. Without it, the result will be a different style of iced coffee.
