Some brewing methods are designed for speed – Vietnamese coffee is not one of them.
The traditional phin filter turns coffee into a ritual. There are no flashing lights, complicated machines, or timers counting down. Just coffee, water, patience, and a slow drip that transforms a simple cup into an experience.
For generations, Vietnamese families have brewed coffee this way. The process is simple, but the results are rich, full-bodied, and deeply satisfying.
If you’ve recently discovered Vietnamese coffee and want to recreate the experience at home, a phin filter is the perfect place to start.
What Is a Vietnamese Phin Filter?
A phin is a traditional Vietnamese brewing device made of metal that sits directly on top of your cup or glass. Hot water slowly passes through the coffee grounds, creating a concentrated and flavorful brew.
Unlike many modern brewing methods, the phin doesn’t rely on pressure, electricity, or paper filters. The slow extraction highlights body, sweetness, texture, and depth while creating a brewing experience that feels intentional and unhurried.
The phin has become one of the defining symbols of Vietnamese coffee culture because it encourages people to slow down and enjoy the process rather than rushing straight to the caffeine.
What You’ll Need
Before you begin, gather the following:
- Vietnamese phin filter
- 20 grams of coffee
- 120–140 ml hot water
- A kettle
- A mug or glass
- Sweetened condensed milk, optional
- Ice, optional
The beauty of phin brewing is its simplicity. Once you have the filter itself, there isn’t much else required.
If you’re exploring different brewing methods beyond the traditional phin, we also recommend reviewing our complete Coffee Brewing Guide. It includes recommended ratios, grind sizes, temperatures, and brewing techniques for pour over, French press, espresso, cold brew, and more.
The Best Grind Size for Vietnamese Coffee
Grind size plays a major role in how your coffee tastes.
For phin brewing, you’ll want a grind that falls between fine and extra-fine.
If the coffee is ground too coarse, water will pass through too quickly and the resulting cup may taste weak or under-extracted.
If the grind is too fine, the brew can become overly bitter or clog the filter entirely.
A properly ground coffee should allow for a slow, steady drip that takes approximately four to six minutes to complete.
The Ideal Coffee-to-Water Ratio
For a traditional Vietnamese phin brew, we recommend:
20 grams coffee : 120–140 ml water
This ratio creates a concentrated cup with excellent body and structure.
Once you’re comfortable with the process, feel free to experiment. Some coffee drinkers prefer a stronger extraction, while others enjoy a slightly lighter cup. Small adjustments can dramatically change the final result.
Step 1: Add Coffee to the Phin
Place your phin filter on top of your cup or glass.
Add 20 grams of ground coffee into the brewing chamber and gently shake the filter to create an even coffee bed.
This helps ensure the water moves through the grounds consistently during brewing.
Step 2: Insert the Press
Place the metal press on top of the coffee.
If your phin uses a screw-style press, tighten it lightly.
A common mistake is pressing too firmly. Excessive pressure can restrict water flow and lead to over-extraction. The goal is gentle contact with the coffee, not compression.
Step 3: Bloom the Coffee
Pour a small amount of hot water over the grounds.
Allow the coffee to bloom for approximately 30 seconds.
This initial wetting releases trapped gases and helps prepare the grounds for a more even extraction.
You may notice the coffee swell slightly as it absorbs water.
Step 4: Fill the Phin
After blooming, slowly add the remaining water until the brewing chamber is full.
Place the lid on top and allow the coffee to drip naturally.
Now comes the most important step:
Wait.
The slow drip is part of the experience. Resist the urge to rush the process.
A proper phin brew should take approximately four to six minutes.
Step 5: Enjoy Your Coffee
Once brewing is complete, remove the phin and enjoy.
You have several options:
- Drink it black to experience the coffee’s full character.
- Add sweetened condensed milk for a traditional Vietnamese preparation.
- Pour over ice for Vietnamese iced coffee.
- Adjust strength to your personal preference.
Each approach highlights different aspects of the coffee.
Why Vietnamese Coffee Tastes Different
The brewing method itself contributes significantly to the flavor, but it is only part of the story. Vietnam’s growing regions, coffee varieties, and processing methods all play a role in creating the distinctive character found in the cup.

The slower extraction creates a cup with greater body and texture than many paper-filter brewing methods. The oils remain in the coffee, adding richness and mouthfeel.
Vietnamese coffees are also often selected and roasted in ways that complement phin brewing, producing a cup that feels bold, layered, and satisfying.
When paired with sweetened condensed milk, the result becomes one of the most recognizable coffee experiences in the world.
But don’t overlook the beauty of drinking it black. High-quality Vietnamese coffee offers remarkable complexity on its own.
More Than a Brewing Method
Learning how to brew Vietnamese coffee is about more than following instructions.
The phin is deeply connected to Vietnam’s coffee culture and history. What began as a practical brewing device eventually became part of daily life across the country. To learn more about how coffee became woven into Vietnamese culture, explore The History of Coffee in Vietnam.
It’s about embracing a different pace.
The phin asks you to slow down. To wait. To pay attention. To enjoy the anticipation as the coffee gradually fills the cup.
In a world built around convenience, that simple act feels increasingly rare.
For many Vietnamese families, coffee has always been tied to connection, conversation, and ritual. The brewing process is part of the experience itself.
At Triều Đại Coffee, we believe that experience matters.
Coffee should be more than something you consume on the way to your next task.
It should be something you experience fully.
Start Your Vietnamese Coffee Ritual
The best way to understand Vietnamese coffee is to brew it yourself.
Whether you’re discovering the phin for the first time or reconnecting with a familiar tradition, the process offers a deeper appreciation for the culture, craftsmanship, and history behind every cup.
Slow down. Let it drip. Enjoy the ritual.
