Short answer: yes, usually it is. Vietnamese coffee is stronger than regular filter coffee, both in taste and caffeine content, for three reasons: bean type, brewing method, and dosage.
Let's go through them.
1. Robusta contains more caffeine
Most Vietnamese coffee is robusta, whereas most European filter coffees are arabica. The difference is not small: robusta typically has about twice as much caffeine as arabica.
Robusta is also fuller-bodied and darker in taste — less acidic, more body, dark chocolate, and roasted grain. This makes the cup both stronger-tasting and more invigorating.

2. Phin filter creates a strong extract
Vietnamese coffee is brewed using a phin filter, which slowly drips water through the coffee using only gravity. The long contact time between water and coffee extracts more — including more oils and flavor — than quick machine filtration.
The result is a concentrated, almost espresso-like extract that doesn't become diluted even with ice or condensed milk.

3. Dosage is more generous
Relatively more coffee is used in a Vietnamese cup: about 20–25 g of ground coffee for only about 80 ml of water. The same amount of grounds would be enough for a significantly larger cup in regular filter coffee. Less water and more coffee mean a stronger result.
How much caffeine is in Vietnamese coffee?
The exact amount varies depending on the bean, dosage, and brewing method, but as a rough guide:
- Regular cup of filter coffee (arabica): about 80–100 mg of caffeine
- Vietnamese phin coffee (robusta): often significantly more, as both caffeine content and dosage are higher
In other words, one small glass of Vietnamese coffee can be as invigorating as a larger cup of regular coffee.
Does stronger mean better?
Not automatically — "strong" is a matter of taste. But if you like a full-bodied, dark, and invigorating coffee, the Vietnamese style offers just that. And because the cup is concentrated, it carries sweetness well: that's why condensed milk and Vietnamese coffee go so perfectly together.
Frequently asked questions
Is robusta worse than arabica? No, it's different. Robusta has a bad reputation as a cheap filler, but well-grown and roasted Vietnamese robusta is full-bodied and nuanced — a different bean for a different purpose.
Can Vietnamese coffee be drunk mild? Yes. Add water or reduce the amount of coffee to taste. You can also choose a softer blend instead of strong robusta.
Does Vietnamese coffee have to be drunk with milk? No. Many drink it black (cà phê đen). Condensed milk is a popular, but optional, addition.
