How to Brew Vietnamese Coffee Using a Drip Filter (Phin)

In Vietnam, coffee isn’t a luxury—it’s a daily ritual enjoyed everywhere from bustling streets to quiet neighbourhood shops. Locals sip slowly, often watching the world go by as a single cup drips drop by drop through a small metal filter. The result? A bold, sweet, and deeply satisfying brew unique to the region.

To make traditional Vietnamese coffee, you’ll need just four things: a phin filter, medium-fine ground Vietnamese coffee, sweetened condensed milk, and around ten minutes of patience. That’s all it takes to craft one of Southeast Asia’s most iconic coffee experiences.

What Is a Vietnamese Phin Coffee Filter?

The ‘drip filter’ used in Vietnam is called a phin (or in Chinese). Unlike a French press or pour-over, the phin is a small metal single-serve dripper that sits directly atop your cup. It works purely through gravity and doesn’t require pumps, paper filters, or machines. The result is a thick, rich brew that highlights the full body and intensity of dark-roasted coffee—often enhanced with plenty of sweetened condensed milk.

Why Vietnamese Coffee Tastes the Way It Does

Vietnamese-style coffee is characteristically strong, sweet, and slow-dripped. Most locals use medium-dark to dark roasted beans, often locally grown, and almost always brew with sweetened condensed milk. The slow extraction through the phin—usually taking around 10 minutes—results in a concentrated coffee that balances bitterness with the sweetness of the milk. Adding ice turns it into a refreshing iced version, popular year-round.

How to Brew Coffee with a Vietnamese Phin Filter: Step by Step

Here’s the exact method used in Vietnam, using a traditional phin, local coffee beans, and condensed milk:

• What you’ll need: Vietnamese phin filter, sweetened condensed milk, medium-fine ground Vietnamese coffee beans, coffee spoon, cup
• Step 1: Disassemble the phin and remove the press plate.
• Step 2: Pour a small amount of sweetened condensed milk into your cup—adjust to taste.
• Step 3: Add approximately 15 grams (about two coffee spoons) of finely ground coffee into the phin chamber. Level it gently with the spoon.
• Step 4: Place the press plate back on top of the coffee grounds and screw it down firmly—but not excessively tight—to allow proper water flow.
• Step 5: Place the phin directly on your cup (which already has condensed milk in it).
• Step 6: Add just enough hot water (just off boil, around 90°C / 194°F) to soak all the coffee grounds—this is the bloom stage. Let it sit for about 20 seconds.
• Step 7: After the bloom, fill the phin with more hot water until it reaches near the top. Do not press or tamp again.
• Step 8: Let the coffee drip slowly—this entire brew process should take around 10 minutes. No need to stir; just wait.
• Step 9: Once the dripping stops (roughly 10 minutes later), stir the brewed coffee with the condensed milk. Enjoy hot, or pour over ice for a chilled version.

Mistakes to Avoid When Using a Phin

Several common errors can ruin your phin-brewed coffee:

• Over-tightening the press plate, which restricts water flow and slows or stops brewing entirely.
• Using too coarse a grind—this leads to under-extraction and weak flavour.
• Not blooming the coffee first with a small amount of water before filling the phin.
• Brewing for less than 10 minutes, resulting in an underdeveloped and thin cup.
• Adding too much water at once, which can flood the filter and disrupt even extraction.

Can You Use Other Coffee Beans in a Phin?

Yes—but traditional Vietnamese coffee uses locally roasted beans, typically dark or medium-dark. These beans are chosen for their bold, sometimes earthy profile that stands up to sweetened condensed milk. However, you can experiment with other full-bodied beans such as dark roasted blends or single origins with chocolatey or nutty characteristics. Just avoid extremely light or fruity roasts, which may clash with the milk.

Frequently Asked Questions

What is a Vietnamese phin filter and where does it come from?

A phin is a small metal single-serve coffee dripper used traditionally in Vietnam. It sits directly on top of a cup and brews coffee through gravity alone. It’s widely used across Vietnam for making strong, slow-dripped coffee, usually served with condensed milk.

Do I need special coffee beans to brew Vietnamese coffee?

No special beans are required, but traditional Vietnamese coffee uses medium to dark roasted beans, often locally sourced. These beans have a bold, sometimes earthy or chocolatey profile that pairs well with sweetened condensed milk. You can also experiment with full-bodied blends or dark roasted single origins.

How long does it take to brew coffee with a phin?

Brewing coffee with a phin typically takes around 10 minutes. This includes a short bloom period (about 20 seconds) and the main drip, which should take roughly 10 minutes in total for a full, concentrated extraction.

Can I make iced Vietnamese coffee with a phin?

Yes. Brew your coffee using the phin as described, then pour it over ice. Many Vietnamese drinkers prefer their coffee cold, and the slow extraction method works great for iced coffee when you want a strong, sweet, and refreshing drink.

Why is my phin coffee brewing too fast or too slow?

If the coffee brews too fast, your grind may be too coarse or the press plate may be loose. If it brews too slowly or not at all, the grind might be too fine or the press plate is screwed on too tightly. Adjust grind size and press pressure for a brew time close to 10 minutes.
