How to Make Vietnamese Coffee

Vietnamese coffee is coffee made from beans grown in Vietnam, brewed through a phin filter and traditionally finished with sweetened condensed milk. The bean is what actually defines it: over 90% of what Vietnam grows and exports is robusta, not arabica. It's served hot as cà phê sữa nóng or over ice as cà phê sữa đá. Here's exactly how to make both, the full picture of why it tastes the way it does, and what to use if you don't have a phin filter.

Robusta vs. Arabica

Vietnam is the world's second largest coffee producer and the single largest producer of robusta, accounting for roughly 70% of all robusta grown and consumed worldwide. Robusta and arabica are different species within the same genus, and they differ in a few concrete ways that matter for how this coffee tastes and brews:

• Caffeine: robusta runs about 2.7% caffeine versus roughly 1.5% for arabica, close to double.
• Flavor: robusta has less sugar and fat, which is why it tastes bolder and more chocolatey rather than bright or fruity.
• Plant and crop: robusta grows taller, tolerates a wider range of climates, and resists disease and pests far better than arabica.

Why This Coffee Comes Out So Strong

Two things compound. First, the bean: robusta's nearly double caffeine content compared to arabica. Second, the brew: the phin filter uses a much higher coffee to water ratio than a typical drip method, producing something closer to a concentrate than a standard cup. Together, that's a cup that's stronger on two separate axes at once, not just one, which is why getting the ratio right in the steps below matters as much as the bean itself.

How Vietnamese Coffee Is Traditionally Brewed

In Vietnam, coffee is most commonly brewed in a phin filter, something like a cross between a pour-over dripper and a French press. Ground coffee sits in a small chamber under a gravity press, and hot water steeps through it slowly, producing a concentrated brew closer to espresso than a standard drip cup. The phin filter is central to Vietnamese coffee culture, but it isn't required. Vietnamese coffee can be brewed however you like, auto-drip, cold brew, espresso, or otherwise, as long as the grind size is dialed in for that method. For the full mechanics of the method itself, see our complete phin brewing guide.

A Little History

Vietnam's relationship with coffee traces back to French colonization in the mid-19th century, when coffee culture arrived along with the rest of the French empire's exports. Plantations spread through the central highlands, a region whose climate and soil turned out to be especially suited to robusta. Over the following century and a half, Vietnam grew into the coffee power it is today, and in the last decade specifically, the industry has shifted from a volume driven market toward a quality driven one, with more farmers investing in specialty grade single-origin robusta rather than the cheap, bulk product the crop was historically known for.

Common Misconceptions

• Condensed milk doesn't make it Vietnamese. Plenty of countries put condensed milk in coffee. What defines Vietnamese coffee is the bean, grown in Vietnam.
• It isn't only served iced. Cà phê sữa đá (iced) is the most recognized version outside Vietnam, but hot Vietnamese coffee, cà phê sữa nóng, is just as traditional.
• The phin filter isn't required. It's the traditional method and produces the closest result to the original, but French press, pour-over, and espresso all work.

Iced Variation: Cà Phê Sữa Đá

This is the version most people picture when they hear “Vietnamese coffee.” Brew as above directly over 2 to 3 tablespoons of condensed milk in a glass, then pour the finished coffee over a full glass of ice and stir well. Because the ice will dilute the drink as it melts, brew slightly stronger than you would for a hot cup: use a scant half tablespoon more coffee, or slightly less water, to compensate. For more iced-specific tips, see our Vietnamese iced coffee guide.

Vietnamese iced coffee isn't the only iced style worth knowing. Cà phê đá is the same coffee served black over ice, no condensed milk, and cà phê bạc xỉu flips the ratio, using more condensed milk than coffee for a lighter, sweeter cup. All three use the same brewing method underneath, the difference is just what goes in the glass with it.

How Long Does Vietnamese Coffee Last?

Whole beans keep for about six months after roasting if stored away from sunlight in a dry, airtight container, and closer to a year in a proper coffee canister. Robusta in particular tends to hold its flavor a little longer than arabica thanks to its higher antioxidant content, often one to two months longer when stored properly. In the freezer, in small sealed packets, beans can stay good for up to three years.
