If you are new to this brew, you may be confused by the lot of information that is floating around Vietnamese coffee. Should you use Robusta or Arabica coffee beans? Is there a difference? Continue reading to clear all misconceptions that you may have about these two types of coffee beans in Vietnamese coffee.
Robusta vs. Arabica for Vietnamese coffee: Difference in taste
Traditionally, Vietnamese coffee is made using Robusta beans. Known for their bold, robust (no pun intended) flavor, Robusta beans give Vietnamese coffee its signature kick. The taste is strong, with a nutty, chocolatey, and somewhat earthy flavor that is often described as having a ‘burnt’ or ‘woody’ aftertaste.
Arabica beans, on the other hand, have a sweeter, softer taste, with tones of sugar, fruit, and berries. Their acidity is higher, with a wine-like flavor, compared to Robusta’s robustness.
- Arabica beans are more acidic than Robusta beans.
- Robusta has almost double the caffeine content per bean compared to Arabica.
- Robusta beans are generally cheaper to produce due to their resilience and the less intensive care needed.
Why are Robusta coffee beans better for Vietnamese coffee?
The strong, intense flavor of Robusta beans mixes perfectly with the sweetness of condensed milk. This combination results in a smooth, rich coffee that packs a punch but still leaves a sweet aftertaste.
Can you make Vietnamese coffee with Arabica beans?
Yes, you can make Vietnamese coffee with Arabica beans. However, the resulting brew will taste noticeably different from the traditional Robusta-based coffee.
Arabica beans will give your Vietnamese coffee a lighter, more acidic taste. The subtlety and complexity of Arabica can be an interesting twist, but it may not provide the same punch as Robusta.
💡 Learn if Vietnamese coffee is worth trying.
Growing conditions
Robusta beans are known for their hardy nature. They thrive in low altitudes (up to 800 m) and warmer climates (ideal is 24-30 Celsius) and are resistant to pests and diseases. This resilience makes them less expensive to cultivate and more widespread.
On the other hand, Arabica beans are high-maintenance. They prefer cooler temperatures (15-24 Celsius) and high altitudes (from 800 m to 2000 m) and require more care and attention. They are also more susceptible to diseases, which, combined with their specific growing conditions, makes them more expensive to produce.
Where are Robusta and Arabica beans grown in Vietnam?
Vietnam is the world’s second-largest coffee producer, with Robusta beans making up the majority of its yield. The Central Highlands of Vietnam is the heart of the country’s Robusta production.
Arabica beans are also grown in Vietnam. However, it is less dominant, considering that 95% of coffee production in Vietnam is centered around Robusta beans.
Preparation: Is there a difference in preparation?
Typically, Robusta beans used for Vietnamese coffee are medium to dark roasted. The traditional Vietnamese method involves using a small metal drip filter (known as a phin), placing the ground coffee inside, and pouring hot water over it.

The coffee then drips slowly into a cup containing a layer of sweetened condensed milk, creating a beautiful balance of strong and sweet.
Preparing Vietnamese coffee with Arabica beans may require a few tweaks. Given the beans’ more delicate and acidic flavor profile, a medium roast is often preferred to preserve the nuanced flavors and aromas.
The brewing process can remain the same. However, due to Arabica’s lighter, more acidic taste, you might want to adjust the amount of condensed milk used to ensure a balanced flavor.
How do you choose the best Robusta beans for Vietnamese coffee?
Here are a few pro tips to guide you:
- Origin: Look for beans that are grown in Vietnam, specifically from the Central Highlands region. This area is renowned for producing high-quality Robusta beans with a rich, bold flavor.
- Roast level: Traditional Vietnamese coffee uses medium to dark roasted Robusta beans. A darker roast reduces the natural bitterness of Robusta and enhances its strong, earthy flavors.
- Freshness: Freshness is key when it comes to coffee. Look for beans that have a roast date on the package, and aim to use them within a month of this date.
- Grind: If you’re using a traditional Vietnamese phin filter, a medium to coarse grind is ideal. This will ensure the water flows through the coffee at the right pace, extracting maximum flavor.
Final thoughts
Traditionally, Robusta beans have been the preferred choice for Vietnamese coffee owing to their bold and robust flavor, which harmoniously blends with the sweetness of condensed milk.
However, it’s not a one-size-fits-all scenario. You can indeed opt for Arabica beans, well-known for their sweeter, softer, and more acidic profile.
