What is Vietnam's Most Famous Coffee Bean? Robusta Flavor! How to Make Drip Coffee? Is Condensed Milk Coffee Delicious?

The Vietnamese didn't originally drink coffee—it was the French who brought it, and only then did coffee weave itself into Vietnamese daily life. Mention "Vietnamese coffee" today and most people think immediately of Robusta. Of the millions of tons of coffee Vietnam produces each year, nearly 97% is Robusta. Vietnam's total output trails Brazil's, but if you count Robusta alone, Vietnam is the world's undisputed number one producer.

"Vietnamese coffee," however, doesn't just mean beans grown and exported from Vietnam—it's also shorthand for the country's signature local drink. From coffee lounges in upscale hotels to unassuming street-corner stalls, you can find this uniquely Vietnamese specialty everywhere. The drink combines condensed milk and strong black coffee. Since that black coffee is built on deeply roasted Robusta—whose bitterness becomes sharp and intense—people add sweetened condensed milk to soften it. Condensed milk and Robusta collide at opposite extremes to create something sweet, rich, and unmistakably Vietnamese.

But condensed milk alone wouldn't have made this a national icon. For that you need the tool the Vietnamese use to brew it: the phin filter. This small device, shaped rather like a water glass, is the soul of Vietnamese coffee.

In a sense the phin is a type of dripper—it, too, is a gravity drip extractor. It has three parts: the filter body, the press plate, and the lid. Using it is simple: add coffee grounds to the chamber, press them down firmly with the plate, pour in hot water, and wait for the coffee to seep through.

The holes aren't especially fine, so smaller particles will slip through. Don't worry, though: once the grounds are firmly compressed, very few escape. Rather than feeling gritty, those fines actually add richness—though the brew may look slightly cloudy. So let's walk through how a traditional Vietnamese coffee is made!

Vietnamese Coffee Preparation

First, the extraction parameters. The phin is a pure drip device—simpler and more direct than most—and since its slow, undisturbed water flow creates no turbulence, we compensate by nudging extraction efficiency up. The parameters I used:

Beans: Sumatra Golden Mandheling
Grind: Ek43 setting 10.5, coarse-sugar texture, 70% pass-through on the #20 sieve
Dose: 15g
Ratio: 1:10
Water temperature: 94°C

Next, prepare the receiving cup—here's where you add the condensed milk in advance. I used 10ml, which gives moderate sweetness; adjust to your own taste. With everything ready, set the phin on the cup and pour in the grounds!

Gently tap the bed level, drop the press plate in horizontally, and press down firmly—this keeps too many grounds from escaping, though it also matters for flow: the harder you compress the bed, the slower the water passes through. I press it down as hard as I can, so under-extraction isn't a concern. Then pour in the water!

Finally, cap it with the lid. The lid isn't there to keep the water warm—it's there to keep the press plate from floating! Hot water makes the plate rise, and without the lid holding it down, grounds would scatter everywhere.

Now just wait for the dripping to finish, and a cup of Vietnamese coffee is ready.

Drink it without stirring: sip slowly from the top and enjoy how the concentration and sweetness shift from light to deep as you descend through the layers. But if the bitterness is too much for you, take a spoon and stir away.

FrontStreet Coffee Recommendation

The deep-roasted Robusta backbone is what makes Vietnamese coffee what it is, but the bean choice shapes the cup. For this brew we used Sumatra Golden Mandheling—but FrontStreet Coffee's PWN Golden Mandheling works just as beautifully in a phin: beans above 18 screen size, Grade G1 quality, triple hand-sorted, and medium-dark roasted for herbal, dark chocolate, and caramel depth with almost no acidity to fight the condensed milk.

If you'd like a softer, more approachable cup, the FrontStreet Classic Blend—Brazil's creamy nuttiness layered with Mandheling's wildness and a touch of Robusta for richness—stands up to sweetened condensed milk effortlessly. And for something fruitier in the Vietnamese style, the low-bitterness FrontStreet Strawberry Candy blend brings strawberry-gummy sweetness that plays wonderfully against the milk syrup.
