Vietnamese coffee is typically prepared using dark-roasted robusta beans with a phin filter and served with sweetened condensed milk and ice. 

There are 4 defining components of Vietnamese coffee:

  1. Origin — Vietnam is the second largest producer of coffee in the world. The rich, volcanic soil, perpetual growing season, and hefty rainfall mark the perfect conditions for cultivating coffee.
  2. Brew — Traditional Vietnamese coffee is brewed using a phin. This small metal filter sits on top of a mug and creates a slow-drip brewing process. The result is similar to an espresso but has up to two times the caffeine content, a thicker consistency, and a stronger taste.
  3. Preparation — Sweetened condensed milk is an essential ingredient in Vietnamese-style coffee, creating a delicious fusion of bold, creamy, and sweet flavors.
  4. Species — Traditional Vietnamese coffee is made exclusively from Coffea robusta, renowned for its strong, slightly bitter, and nutty flavor profile.

In this article, we explore the traditional Vietnamese brewing and serving process that sets it apart from other types of coffee.

What Makes Vietnamese Coffee Special?

One of the most obvious things that differentiates Vietnamese coffee from other types is that it’s grown in Vietnam. 

Unlike other types of coffee, which tend to use the Coffea arabica bean or a blend of beans with a higher concentration of arabica, Vietnamese Coffee is made using only Coffea robusta.

Robusta contains up to two times the amount of caffeine compared to arabica and a much stronger flavor. In order to balance this bold, intense flavor, Vietnamese coffee also contains sweeteners (usually condensed milk).

The hot climate in Vietnam also means coffee prepared here is typically iced rather than kept hot.

A Brief History of Vietnamese Coffee

Vietnam was a French colony from 1883 to 1954. During this time, the French installed a rich coffee culture throughout the country, which continued to flourish over generations to evolve into what it is today.

Early French colonists were attracted to the fertile volcanic soil of Vietnam — particularly in Ninh Bình and Quảng Bình provinces. 

Throughout France’s occupation, they could never get the coffee industry to boom. Labor shortages and devastating plant diseases like coffee rust destroyed their arabica plantations — leading to a significant shift towards the more resistant robusta variety. 

After overcoming setbacks from the Vietnam War and the end of French rule, the Vietnamese government encouraged coffee production in the highlands through incentives such as tax exemptions and subsidies. This led to a resurgence in coffee farming, particularly of robusta, which saw a significant boom in the late 20th century. 

Vietnam became a key player in the global coffee industry in the 1990s and has maintained this title ever since.

Vietnam is the Second-Largest Coffee Exporter in the World

In 2023, Vietnam exported 29.7 million bags of coffee — establishing them as the second largest producer in the world (behind Brazil at 39 million bags). 

The majority of Vietnamese coffee exports consist of Coffea robusta (95%), but the country also produces arabica, cherri, moka, and culi coffee beans. Vietnam accounts for 50% of the world’s supply of robusta beans.

In terms of land mass, Vietnam ships roughly 2.9 tons of coffee per hectare of land. Compare this to Brazil, which produces about 1.4 tons per hectare.

How To Brew Authentic Vietnamese Coffee

The brewing process of Vietnamese coffee is important to get right if you want to achieve the bold, intense flavors this coffee is famous for.

Vietnamese coffee is traditionally brewed using a phin filter — which is a small metal filter that works like a cross between a French press and a drip coffeemaker.

A phin employs a slow-drip brewing process that allows the coffee to steep slowly and thoroughly over several minutes. This results in a stronger, more heavily caffeinated cup. 

Once brewed, it's traditional to combine other ingredients, such as heavy condensed milk and ice, into the mix. Some people choose to add other flavors as well, such as caramel, cardamom, or vanilla, to further reduce bitterness. 

If you want to try to make some at home, you can buy a phin from Cafely.com.

Tools & Ingredients

  • Phin Filter — A small metal filter that combines immersion brewing (like a French press) and drip coffee systems to brew a strong, full-bodied coffee.
  • High-quality Vietnamese Coffee — Choose freshly roasted Coffea robusta for best results. The stronger, the better. We recommend our Saigon OG blend (Robusta and Arabica blend), Hanoi (100% Vietnamese Peaberry Robusta) or Da Lat (Vietnamese Arabica)
  • Sweetened Condensed Milk — Canned condensed milk provides the sweetness to balance the bold flavors of dark-roasted Vietnamese Robusta. You’ll need 2 tablespoons (30 mL) per 5 oz (148 ml) of coffee.
  • Coffee Grinder — A burr grinder is preferable, but a blade grinder or small blender will do the job. Aim for a fine grind with a sand-like consistency.
  • Hot water — You will need a ratio of around 1:2 or 1:4 coffee to water. The amount of water required will depend on the size of your phin kit.
  • Ice (Optional) — Fill your cup to the brim with ice and pour freshly brewed coffee over the top. Skip this ingredient if you want a hot cup of coffee.
  • Heat Resistant Mug or Glass Cup — Traditional Vietnamese iced coffee is served in a glass cup, but make sure it is heat resistant. The final brew will be cold, but you’ll still need to use hot coffee for the first pour.

Step-By-Step Instructions for Brewing Vietnamese Coffee

Check out our full brew guide to learn the ins and outs of brewing authentic Vietnamese-style coffee:

  1. Measure & Grind the Coffee — Use a medium-fine grind or order Cafely’s pre-ground coffee to skip this step.
  2. Assemble the Phin Filter — Place the filter plate on your cup and add the brew chamber. The gravity press and lid will be required later, so keep them on hand.
  3. Add Coffee Grounds — For a 6 oz filter, add about 21 grams (3 tablespoons) of coffee. Adjust depending on which filter you’re using.
  4. Add the Gravity Press — Even the coffee grounds by shaking the filter. Add the gravity press using very light pressure for even distribution.
  5. Add the Water (Bloom Stage) — First, add a small amount of water to "bloom" the coffee. This helps eliminate air pockets trapped between grinds to ensure a more consistent and efficient extraction. Pour enough water to cover the gravity press slightly, and allow 45 seconds for the gases to escape.
  6. Add the Rest of the Water (Extraction Stage) — Now, fill the chamber to the top with hot water and leave your phin to sit for 5–6 minutes to finish extracting.
  7. Add Sweetener — Traditional Vietnamese coffee is made with sweetened condensed milk, but you can use regular milk, sugar, or other creams to sweeten. We recommend 2 tablespoons (1 oz) of condensed milk.
  8. Add Ice (Optional) — Add enough ice to fill the volume of your cup. You want to bring the core temperature of the coffee down as quickly as possible. Let it sit for two minutes before drinking so it is nice and cool.

Feel free to experiment with the ratio of coffee to water and different sweeteners to suit your preferences.

Other Ways to Make Vietnamese Coffee

While the phin filter is the most traditional method of making Vietnamese coffee, you can use pretty much any brewing system to make it, too. The best Vietnamese coffee comes from brewing techniques known for crafting concentrated coffees. This means more diluted brewing methods like pour-over, drip coffeemakers, and siphon coffee aren't ideal. To compensate for this, some people simply use more coffee grounds than they normally would during brewing to get a stronger, more intense extraction.

Here are 4 brewing systems that can be used to make delicious Vietnamese coffee:

  1. French PressBrew extra strong with a 1:2 or 1:3 ratio of coffee to water.
  2. AeroPress — Use like a phin filter, allowing the hot coffee to drip through the press and into your cup. If the brew is taking to long, use the included plunger to force the coffee into your cup.
  3. Espresso Use 1 shot of espresso for every 2 ounces of Vietnamese coffee. 
  4. Moka Pot Opt for Vietnamese robusta for the most authentic taste possible. Brew as normal and combine with condensed milk over ice.

The Vietnamese Phin Filter

At the heart of Vietnamese coffee culture sits the phin filter — a compact, drip-style coffee maker crafted from metal. It’s perfectly suited to the deep, rich, and intense flavors extracted by Vietnamese robusta coffee.

It was invented sometime in the 20th century and was quickly adopted for its low cost, simple design, and absence of disposable filters or waste. A good phin filter will last a lifetime of use.

This device is straightforward to use but might require some practice to get it just right. 

Anatomy of a Phin Filter

The phin consists of 4 key parts: 

  1. The Cap — Used to maintain the water's heat as the coffee brews.
  2. The gravity press — A small tamper to ensure a thorough and consistent extraction. 
  3. The brew chamber — This is the body of the phin where the coffee steeps in water.
  4. The filter plate — A built-in filter separates the fresh coffee from the grounds (no paper filters needed). 

What is Vietnamese Robusta Coffee?

Coffea arabica has been the world’s go-to coffee for a long time, but this bean is very finicky to grow. It requires very high altitudes, plenty of rain, and year-long growing seasons to thrive. Arabica grown in lower altitudes, even in tropical areas, develops a strong acidic flavor.

In Vietnam, the highest mountains rarely exceed 1500 meters in elevation. While there are farms in the higher central highlands growing arabica, most farms have switched to growing robusta — which thrives in lower altitudes, is drought-resistant, and produces consistent, high-quality yields all year long.

Through climate adaptations, along with a rich basalt soil that supports some of the highest quality coffee plantations in Southeast Asia, Vietnam has earned a name for the often maligned robusta bean.

The traditional brewing process for Vietnamese coffee is specially adapted for brewing robusta. The phin filter ensures a full extraction of the beans rich, earthy flavors, and the sweetened condensed milk does a perfect job of cutting the more bitter side of this intense bean.

Coffee may have been introduced to Vietnam by the French, but over the years, the local population has put their own spin on things to create coffee that the world has never seen before. You might think that we’re inventive in the Western world with our mochas, frappuccinos, and flavored lattes, but these likely wouldn’t cut the mustard in a place that has introduced egg, condensed milk, fermented rice, yogurt, and fresh fruit into their drinks. 

Vietnamese Coffee vs. Other Southeast Asian Coffees

Coffee is popular throughout most of Southeast Asia, especially in Vietnam, Indonesia, and Malaysia. All 3 have developed their own unique culture, complete with distinctive recipes and bean varieties developed over generations.

The tropical climate of Southeast Asia is perfect for growing coffee. This part of the world accounts for 29 million bags of coffee annually.

Southeast Asian coffee styles typically use robusta (which thrives better in hotter regions with low altitudes), are prepared over ice, and combine local fruits and spices (such as coconut, chocolate, or cinnamon).

Examples of other Asian coffee styles:

  • Thai Coffee (Oliang) — A blend of coffee, sesame seeds, and sometimes corn, served sweetened and iced.
  • Indonesian Coffee (Kopi Tubruk) — Coffee where grounds are boiled along with sugar and served without filtering.
  • Kopi Luwak — Made from coffee beans that have been digested and excreted by the civet, known for its distinctive and smooth flavor. (Called Cà Phê Chồn in Vietnam and Kapeng Alamid in the Philippines).
  • Malaysian Coffee (Kopi-O) — Black coffee brewed using robusta and a traditional sock filter, served with sugar. Coffee served with milk is called Kopi Susu.
  • Ipoh White Coffee — Coffee beans roasted with palm oil margarine and served with condensed milk. Very similar to Vietnamese butter-roast coffee. Popular in Malaysia.
  • Filipino Barako Coffee — Made with Coffea liberica and known for its very strong flavor. Served hot, cold, black, or with milk.
  • Laotian Coffee — Mostly robusta and arabica blends, often served strong and with sweetened condensed milk, similar to Vietnamese styles.
  • Burmese Coffee (Café Yauk) — Typically brewed strong and served sweet with condensed milk, similar to Thai and Vietnamese coffee styles.
