If Vietnamese iced coffee hits harder than your usual iced latte, you might be wondering exactly how much caffeine is in it. Understanding caffeine in Vietnamese iced coffee is important whether you’re tracking your daily intake, comparing it to other iced drinks, or simply curious about why it feels so energizing. Vietnamese iced coffee is naturally strong because of how it’s brewed and the type of beans used.
Key takeaways: What will you learn?
- How much caffeine is in a typical Vietnamese iced coffee.
- Why this drink is naturally stronger than most iced coffees.
- How Robusta beans and the phin brewer affect caffeine levels.
- How Vietnamese iced coffee compares to espresso, drip coffee, cold brew, and iced lattes.
What Is Vietnamese Iced Coffee?
Vietnamese iced coffee is made with strong dark-roasted coffee, sweetened condensed milk, and ice. It is traditionally brewed using a phin filter, a small metal brewer that slowly drips hot water through the grounds to create a concentrated coffee base.
Most Vietnamese coffee is made using Robusta beans, which contain nearly twice the caffeine of Arabica and produce a deeper, more intense flavor.

How Much Caffeine Is in Vietnamese Iced Coffee?
A typical serving of Vietnamese iced coffee contains about 100 to 130 mg of caffeine, depending on how it is brewed.
Here is our calculation:
According to available caffeine data, Robusta coffee contains about 265 mg of caffeine per 8 fl oz. From that, we can estimate the caffeine in a standard phin brew:
- 265 mg / 8 fl oz = about 33 mg of caffeine per fl oz
- A typical Vietnamese phin produces about 3-4 fl oz of brewed coffee
- So a serving contains roughly 100-130 mg of caffeine
Factors That Change the Caffeine Level
The caffeine in Vietnamese iced coffee can vary depending on how you brew it. Here are the main factors that influence the final caffeine content:
- Bean type: Robusta beans contain almost twice the caffeine of Arabica. A blend will lower or raise caffeine depending on the ratio.
- Grind size: A finer grind extracts more caffeine because water stays in contact with more surface area.
- Brew time: A slow phin drip pulls out more caffeine than a fast drip. Longer extraction equals a stronger brew.
- Coffee dose: Using more grounds increases total caffeine. A larger filter chamber or heaping scoop raises the amount easily.
- Serving size: A bigger brew (5-6 ounces vs 3-4 ounces) increases total caffeine even if the concentration stays the same.
Why Vietnamese Iced Coffee Is Stronger Than Most Iced Coffees?
Traditional Vietnamese coffee uses Robusta beans, which naturally have almost twice the caffeine of Arabica beans. This higher Robusta caffeine content creates a bold and strong coffee brew that feels more energizing even in small servings.
Caffeine in Vietnamese Iced Coffee vs Other Coffee Drinks
Below is a quick comparison to show how Vietnamese iced coffee measures up against other popular coffee types in terms of caffeine strength.
Vietnamese Iced Coffee vs Espresso
- Vietnamese iced coffee (4-6 oz): 100-130 mg caffeine
- Espresso (1 oz): 63 mg caffeine
Vietnamese Iced Coffee vs Drip Coffee
- Vietnamese iced coffee: 100-130 mg caffeine
- Drip coffee (8 oz): 95-120 mg caffeine
Vietnamese Iced Coffee vs Cold Brew
- Vietnamese iced coffee: 100-130 mg caffeine
- Cold brew (12 oz): 150-200 mg caffeine
Vietnamese Iced Coffee vs Iced Latte
- Vietnamese iced coffee: 100-130 mg caffeine
- Iced latte (1-2 espresso shots): 60-120 mg caffeine
Can You Reduce the Caffeine in Vietnamese Iced Coffee?
Yes. If you want a lighter version with less caffeine, you can adjust the brewing method without losing the classic flavor.
- Use Arabica blends: Arabica beans have significantly less caffeine and produce a smoother, milder cup.
- Reduce the coffee dose in the phin: Use a level scoop instead of a heaping one to naturally reduce extraction.
- Switch to a medium roast: Medium roast has slightly less caffeine than a dark roast and creates a softer flavor profile.
Can You Make a High-Caffeine Version on Purpose?
If you want a stronger version, you can intentionally increase the caffeine level while keeping the flavor balanced.
- Increase the grounds: Fill the phin filter basket to the top with a heaping amount of coffee.
- Use a finer grind: A slightly finer grind extracts more caffeine during the brew. Just avoid going too fine or the phin may clog.
- Extend the bloom time: Let the coffee bloom longer before adding the rest of the water. This increases extraction and produces a stronger brew.
FAQ
Is Vietnamese iced coffee stronger than regular iced coffee?
Yes. Vietnamese iced coffee is brewed with a concentrated phin drip and often uses Robusta beans, which naturally contain more caffeine. Even though the serving size is small, the coffee is stronger and tastes more intense than regular iced coffee made with drip-brew or lighter roasts.
Does using Robusta beans increase caffeine?
Yes. Robusta beans have almost twice the caffeine of Arabica beans. If your Vietnamese iced coffee is brewed with 100 percent Robusta or a high-Robusta blend, the caffeine level will be noticeably higher.
Does adding more condensed milk change the caffeine content?
No. Condensed milk does not affect caffeine levels. Adding more condensed milk only increases sweetness and calories. The caffeine comes entirely from the coffee itself, not the milk.
