Short answer: yes, usually. Vietnamese coffee is stronger than regular filtered coffee, both in taste and caffeine content, for three reasons: bean type, preparation method, and dosage.
Let's go through them.
1. Robusta contains more caffeine
Most Vietnamese coffee is robusta, while most European filtered coffees are arabica. The difference is not small: robusta typically has about twice as much caffeine as arabica.
Robusta also has a fuller, darker flavor — less acidic, more body, dark chocolate, and roasted grains. This makes for a cup that is both stronger in taste and more invigorating.
2. The phin filter makes a strong extract
Vietnamese coffee is made with 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. The 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 of regular filtered 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 preparation method, but as a guide:
- A regular cup of filtered coffee (arabica): about 80–100 mg of caffeine
- Vietnamese phin coffee (robusta): often significantly more, as both the 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 rich, dark, and invigorating coffee, the Vietnamese style offers just that. And because the cup is strong, it carries sweetness well: that's why condensed milk and Vietnamese coffee go together so perfectly.
Frequently asked questions
Is robusta inferior to arabica? No, it's different. Robusta has a bad reputation as a cheap filler, but well-grown and roasted Vietnamese robusta is rich 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 milder 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.
