Vietnamese Iced Coffee Recipe (Cà Phê Sữa Đá)

As a Vietnamese, I’ll show you exactly how to make authentic Vietnamese iced coffee (cà phê sữa đá) with the traditional methods locals use, including the “golden ratio” that perfectly balances the bold bitterness of Robusta coffee with the sweet creaminess of condensed milk.

What is Vietnamese Iced Coffee?

Vietnamese iced coffee is a distinctive drink that combines strong, concentrated Robusta coffee brewed through a traditional phin filter with sweetened condensed milk. This iconic Vietnamese beverage has gained worldwide recognition for its unique flavor profile, a perfect harmony of bitter, sweet, creamy, and refreshingly cold.

The “Golden Ratio”

Many beginners make Vietnamese iced coffee by feel, mixing coffee and milk without proper measurements. This often results in drinks that are too sweet or too bitter. Here are my recommendations:

• 1:1 Ratio (20g Coffee : 20g Condensed Milk): This is the Classic Street Style ratio. Moderately sweet, creamy, and very rich. I recommend this for first-timers.
• 1.5:1 Ratio (30g Coffee : 20g Condensed Milk): This is the Modern ratio. Less sweet with more pronounced coffee flavor. Perfect for those who want to appreciate the Robusta beans.

Vietnamese Iced Coffee Recipe

Equipment

• Vietnamese phin filter
• Glass cup

Ingredients

• 20g Vietnamese coffee grounds (medium dark roasted Robusta)
• 20g sweetened condensed milk
• 90ml boiling water (95°C / 203°F)
• Ice cubes

Instructions

Step 1: Add Condensed Milk

Add 20g of sweetened condensed milk to your glass.

Adding milk first allows the hot coffee dripping from the phin to “cook” the milk slightly, enhancing the aroma of your coffee. Vietnamese locals typically use Ông Thọ brand condensed milk, but any sweetened condensed milk will work.

Step 2: Preheat the Phin

Rinse the phin with hot water to increase heat retention and maintain stable temperature throughout the brewing process, which helps extract better flavor from the coffee.

Step 3: Bloom the Coffee

Add 20 grams of Vietnamese coffee grounds to the phin and shake gently to level it. Pour 30ml of boiling water over the grounds to cover them evenly. Let it bloom for 40 seconds, allowing the coffee to expand evenly.

Blooming is crucial, it helps the grounds expand uniformly, releases CO2, and extracts rich, aromatic flavors.

You can purchase Vietnamese coffee from brands like Trung Nguyên or Nguyen Coffee Supply.

Step 4: Add Water

After the coffee has bloomed evenly, gently press down the coffee grounds with the filter press, then add 60ml of boiling water to the phin and close the lid.

Pro-tip: Don’t press too hard, as this can block the flow.

Step 5: Wait for Extraction

You’ll see coffee starting to drip down. Wait until the extraction is complete and no more drops fall (approximately 5 minutes).

Step 6: Stir and Add Ice

Use a spoon to stir the milk and coffee layers together, add ice, and enjoy.

What Makes a Perfect Vietnamese Iced Coffee

If you’re new to this drink and wondering whether you’ve made it correctly, here are the telltale signs. An authentic Vietnamese iced coffee should meet these criteria:

Aroma

This is the easiest indicator to judge whether your cà phê sữa đá is good. From the moment you bloom the coffee, you should smell the distinctive Robusta aroma: strong, intensely fragrant, with hints of chocolate or caramel. The coffee scent remains prominent even after mixing with condensed milk and ice. There should be no burnt or charred smell.

Body

The coffee must have a heavy body. Even when mixed with condensed milk, it shouldn’t taste weak or watery. When you take a sip, you should feel the “weight” and richness—not thin like pour-over coffee.

Balanced Finish

The sweetness, creaminess, and bitterness should be perfectly balanced, without an overpowering sweetness that sticks in your throat. Despite the added milk, you should still clearly taste the coffee. The aftertaste is rich, with lingering aroma that lasts several seconds after swallowing.

Texture

The coffee and milk should blend smoothly without separating into layers. When shaken or stirred, it should have a uniform milk-chocolate color that looks silky and smooth.

Tips from a Local

Coffee Type

You must use Robusta. You can use 100% Robusta or blend it with 70% Robusta and 30% Arabica if you want a fruity aroma with a slight acidity.

You can find Vietnamese coffee from Trung Nguyên or Nguyen Coffee Supply, they sell in the US and many countries worldwide.

Grind Size

The beans should be ground to a medium-coarse consistency, similar to the size of sand grains.

Grind size comparison: Pour over < Phin < Espresso

Which Condensed Milk to Use?

Vietnamese people typically use “Sữa Ông Thọ” (Longevity Brand) or “Ngôi Sao Phương Nam” (Southern Star). You can find these on Amazon or at Vietnamese grocery stores in your area. If unavailable, you can substitute with low-sugar condensed milk, which won’t overpower the coffee flavor and helps the coffee taste more aromatic.

Ice

Use large ice cubes to prevent the coffee from becoming too diluted too quickly. If the coffee is still hot, let it cool slightly before adding ice.

How to Enjoy

Vietnamese iced coffee tastes best when enjoyed in the morning, sipped slowly and leisurely. If possible, pair it with some cookies to fully appreciate the difference.
