Vietnamese Coffee: Robusta, Phin Filter and Sweet Condensed Milk

A country that drinks and exports almost only robusta

Vietnam is the world's second largest coffee producer after Brazil. Output for 2025 and 2026 is forecast at around 30 million 60-kilo bags. About 95 percent of that is robusta. That makes Vietnam by far the world's largest robusta producer, supplying more than 40 percent of the global robusta crop. Most of it ends up in instant coffee and industrial espresso blends in Europe and the Americas. A small, growing share stays in the country and is turned into Vietnamese coffee, the way Vietnamese people drink it themselves.

How coffee came to Vietnam

French missionaries brought the first coffee trees to Vietnam around 1857. With French colonial rule came plantations, especially in the Central Highlands around Buôn Ma Thuột. Robusta grew better there than arabica, was less prone to coffee leaf rust and produced higher yields. That decision still shapes the country today. After the Đổi mới reforms in the late 1980s, Vietnam's economy opened up and coffee farming exploded. In just a few years, an unimportant producer became the world's second largest.

The phin filter

Order a coffee in Vietnam and you'll usually get it served with a small metal filter sitting on top of your glass, slowly dripping away. That's the phin. The word comes from the French "filtre". The phin has four parts: a saucer that catches drips, a cup with small holes in the bottom, a press disc that keeps the grounds flat and a lid. You add about two tablespoons of coarsely ground coffee, press it lightly, pour a little hot water first for a short bloom, then add the rest. Then you wait. For four to five minutes, the coffee slowly drips into the glass below.

The result is dense, strong and in terms of mouthfeel close to a strong French press. Thanks to the high share of dark-roasted robusta it tastes bitter and chocolatey and has nearly double the caffeine of an arabica coffee. That's exactly what it was built for.

Cà phê sữa đá

The most famous Vietnamese coffee drink. Cà phê means coffee, sữa means milk, đá means ice. Before brewing, a generous layer of sweetened condensed milk sits at the bottom of the glass. The phin sits on top and drips. Once it's done, you stir coffee and condensed milk together, pour everything over a second glass full of ice cubes, and drink. The result is sweet, strong and cool. In the heat of the Mekong delta or Saigon, that makes more sense than any cold brew from up north.

The condensed milk isn't a coincidence. During the colonial era, fresh milk was scarce in Vietnam. What little there was spoiled fast in the heat. Imported sweetened condensed milk lasted longer and was cheaper. A necessity became a classic.

Cà phê trứng, the egg coffee from Hanoi

In the north, in Hanoi, there's another specialty. In 1946, Nguyễn Văn Giảng worked as a bartender at what was then the Sofitel Legend Metropole. Fresh milk was scarce. Instead of missing it, he whipped egg yolk with condensed milk and sugar into a dense, foamy crème and spooned it onto strong phin coffee. Shortly after, he opened Café Giảng, which still exists today. The drink is called cà phê trứng, egg coffee, and tastes more like a tiramisu you can drink through a straw. Sweet, velvety, with a faint vanilla note. A tourist draw, and rightly so.

More variations the country knows

Cà phê cốt dừa is coconut coffee. Instead of condensed milk you use coconut milk or a mix of both. Sometimes the coconut milk is frozen and served as a crushed-ice slush. Very popular in Hanoi.

Cà phê muối, salt coffee, is a relatively new invention from Huế. A small pinch of salt softens the bitterness of the robusta and brings out an almost caramel-like sweetness. Sounds strange, works surprisingly well.

Bạc xỉu is the Saigon version with considerably more condensed milk and less coffee. The name comes from Cantonese and means "a little bit of white". A friendly gateway drink for anyone who still finds regular cà phê sữa đá too strong.

Does Vietnam also have good specialty coffee?

The short answer: yes, but slowly. In the Central Highlands and the hills around Đà Lạt, more and more small farms and cooperatives have emerged since around 2010 focusing on arabica or on better processed robusta. There's now Fine Robusta, deliberately grown as a single variety, carefully fermented and dried. The result is surprising: less rubbery bitterness, more chocolate, tobacco, sometimes even dark berries. If you've only ever known Vietnamese coffee as bitter robusta, this opens up a different world.

How to recreate it at home

You need a phin filter, which Swiss Asian grocery stores or online shops sell for about CHF 10 to 20. Plus coarsely ground coffee, ideally a dark espresso blend with some robusta in it. Pure arabica specialty often tastes thin in a phin, because the whole brew method is built around dense, strong coffee. Sweetened condensed milk is in every larger supermarket, often in the baking aisle. Two tablespoons in the glass, phin on top, brew, stir, pour over ice.

If you want it more authentic, add a dark-roasted robusta. If you want it more elegant, try a good Fine Robusta or a Vietnamese arabica from Đà Lạt. Both paths work. If you're looking for Swiss specialty coffee with a higher robusta share, have a look at our marketplace. Most Swiss roasteries work with arabica, but some deliberately offer espresso blends with a small share of robusta.

Why it's worth trying

Specialty coffee often revolves around light roasts, fruity single origins and pour-over rituals. That's one world. Vietnamese coffee is another. Dense, dark, sweet, sometimes with egg or salt. Not better or worse, just a different understanding of what a cup of coffee can be. Anyone who knows both drinks their coffee with more curiosity and less dogma. And that's usually the better coffee.
