How to Brew Coffee with a Vietnamese Drip Filter

If you’ve tried just about every coffee gadget out there and are looking for something different—something compact, no-frills, and easy to use anywhere—then the Vietnamese drip filter might be your next favorite. It’s not just for traditional Vietnamese coffee; it’s a straightforward way to make a single cup using nothing but hot water, ground coffee, and gravity.

To make coffee with a Vietnamese drip filter, you’ll need about 2 to 3 minutes total: 15–20 seconds for the bloom, then slow pouring until full, and another 2–3 minutes for the full drip-through. The result is a mild, clean cup—lighter than espresso but richer than instant.

What Is a Vietnamese Drip Filter?

The Vietnamese drip filter, often called a ‘phin’ or ‘Vietnamese coffee dripper,’ is a small metal or stainless-steel device that works purely through gravity-based drip extraction. There’s no pump, no pressure, just a chamber for coffee grounds, a filter plate, and a drip spout. You pour hot water over the grounds, let it bloom, then add more water slowly. The brewed coffee drips directly into a cup or glass below.

It’s ultra-portable, requires no electricity, and is often used while traveling or in offices. Though it’s associated with traditional Vietnamese coffee culture, it can work with any coffee beans—not just the dark, strong Robusta typically used in Vietnam.

Why Use a Vietnamese Drip Filter?

This method is ideal when you want a simple, single-serve coffee without a machine. It’s great for travel, small kitchens, or offices where electric brewers aren’t available. The design is intentionally minimal—just a few parts to assemble—and relies entirely on gravity and time for extraction.

For coffee drinkers who enjoy espresso-like strength but don’t want to pull a shot, this method offers a middle ground. Though the default Vietnamese style uses sweetened condensed milk, you can easily customize the brew to be black or use alternatives like milk powder or creamer.

How to Make Coffee with a Vietnamese Drip Filter

What You’ll Need

• Vietnamese drip filter (phin)
• Coffee cup or glass (preferably clear to watch the drip)
• Ground coffee (1.5 scoops recommended for stronger flavor)
• Hot water (around 90°C / 194°F)
• Optional: milk, creamer, or sweetener

The process is straightforward, but small tweaks in grind size, water temperature, and blooming time affect the final cup. Here’s how to do it step-by-step:

Step 1: Add Coffee Grounds

Place about 1.5 scoops (more if you want a stronger brew) of ground coffee into the filter chamber. The article suggests using a medium to finer grind—similar to what you’d use for espresso or a very strong pour-over. The exact grind isn’t specified, but fine enough to slow the drip is key.

Step 2: Attach the Filter Plate

Screw down the filter’s top plate to gently compress the coffee. Don’t overtighten—it should be snug, not sealed. The tightness of this screw directly affects how fast the water drains. A looser fit means slower brew time and stronger flavor extraction; tighter means faster flow and a lighter cup.

Step 3: Bloom the Coffee

Pour a small amount of hot water—just enough to wet the grounds (no more than the volume of the coffee bed)—and let it sit for 15–20 seconds. This bloom step releases gases and prepares the coffee for better extraction. The water should be around 90°C (not boiling) to avoid scorching the grounds.

Step 4: Add More Water and Brew

After the bloom, slowly pour more hot water until the chamber is nearly full. Do this steadily and avoid dumping water quickly, which can cause uneven extraction. Then place the lid on top to retain heat and wait.

The coffee will begin dripping through the bottom—a process that takes roughly 2 to 3 minutes. Let it fully drain before removing the filter.

Step 5: Serve and Customize

Once the dripping stops, your coffee is ready. Traditionally, Vietnamese coffee is served with sweetened condensed milk (called ‘fresh milk’ locally but actually a thick, sweetened evaporated product), but the author prefers a milder option like milk powder or non-dairy creamer to avoid excessive sweetness.

You can also enjoy it black if you prefer a lighter, less intense cup. Either way, the final brew is milder than espresso, smoother than instant, and uniquely clean for a drip method.

Flavor Notes & Customization

The original Vietnamese style uses Robusta beans, which are more bitter, stronger, and less aromatic than Arabica. To avoid that profile, the author uses their own Italian-style beans instead. They recommend using 1.5 scoops to compensate for the naturally lighter extraction from the drip method.

The final taste is clean, straightforward, and easy-drinking. Without milk or sugar, it’s mild—but with additions, it becomes a customizable everyday drink. Adjust the coffee dose or brew time slightly to tweak strength as needed.

Frequently Asked Questions

What kind of coffee beans work best in a Vietnamese drip filter?

You can use any coffee beans, though medium to dark roasts tend to mimic the traditional Vietnamese style. For a less bitter, more nuanced cup, try a medium roast Arabica instead of robusta. The article’s author uses their own Italian beans rather than traditional Vietnamese Robusta for a better-tasting result.

What grind size should I use for a Vietnamese coffee filter?

The ideal grind is medium to fine—similar to espresso or a very strong pour-over. It should be fine enough to slow the dripping process but not so fine that it clogs the filter. The exact setting isn’t given, but aim for a grind that allows a 2–3 minute total brew time.

Do I have to use sweetened condensed milk?

No. While sweetened condensed milk is traditional in Vietnam, you can use milk powder, regular milk, non-dairy creamer, or drink it black. The author prefers a milder creamer to avoid the intense sweetness of condensed milk.

How long does the brew take?

Total brew time is around 2 to 3 minutes once all the water has been added. This includes a 15–20 second bloom, then slow pouring and dripping. The speed depends partly on how tightly the filter’s top screw is adjusted.

Can I make Vietnamese drip coffee without a special filter?

No—you need the specific Vietnamese drip filter (phin) with a built-in chamber, filter plate, and slow-drip mechanism. It’s a unique brewer that works only with its own design, relying on gravity and controlled flow.

Is Vietnamese drip coffee strong?

It can be, depending on the coffee dose and brew time. The author uses 1.5 scoops to increase strength since drip methods are generally milder. The final cup is lighter than espresso but stronger than instant coffee.
