How to Brew Coffee with a Vietnamese Phin Filter

If you’ve ever sipped thick, sweet Vietnamese coffee with a velvety layer of condensed milk at the bottom, you know there’s something uniquely satisfying about it. But replicating that rich, bold cup at home isn’t always straightforward—especially if you’ve never used a Vietnamese phin, or ‘drip filter.’

To make traditional Vietnamese-style coffee with a phin, use finely ground dark roast coffee, 15 grams per cup, two tablespoons of condensed milk, and brew for around three minutes. That’s the core formula—but getting the grind, water timing, and pressure just right makes all the difference.

What Is a Vietnamese Phin Filter?

Vietnamese coffee culture is distinct for its use of dark-roasted beans and a simple metal drip filter called a phin (or “dripper”). Unlike pour-over cones or espresso machines, the phin sits directly atop your cup and drips coffee slowly through a single filter chamber. The result? A strong, concentrated brew that’s customarily mixed with sweetened condensed milk.

Why Add Condensed Milk—and Why Go Dark Roast?

Vietnamese coffee almost always includes sweetened condensed milk. This addition is nearly unique to Vietnam and creates a creamy, dessert-like contrast to the intense bitterness of the dark roasted beans. Most traditional recipes also call for ice, turning the drink into a refreshing iced coffee. The deep roast—similar to a French or Italian style—brings out heavy chocolate, caramel, and toasted notes that stand up to the milk and enhance body.

How to Use a Vietnamese Phin Filter Step by Step

Here’s exactly how to brew one cup using the traditional method:

• What you’ll need: A Vietnamese phin filter, finely ground dark roast coffee (~15g), condensed milk, a coffee spoon, and a cup.
• Step 1: Disassemble the phin and remove the press plate.
• Step 2: Pour 1–2 tablespoons of condensed milk into your cup.
• Step 3: Add approximately 15 grams (about two coffee spoons) of freshly ground dark roast coffee. Grind size should be very fine—closer to espresso than pour-over.
• Step 4: Level the coffee grounds gently with the back of the spoon, then place and tighten the press plate over them.
• Step 5: Place the phin directly on your cup. Pour just enough hot water (just off boil, around 90°C / 195°F) to soak the coffee grounds—but not so much that it drips through. This is essentially a bloom, and you should let it sit for about 20 seconds.
• Step 6: After the bloom, pour more hot water to fill the phin and cup. Do not tamp again.
• Step 7: Let the coffee drip through—this should take roughly three minutes. No need to stir. Once it’s fully dripped, your coffee is ready.

What Makes the Phin Unique?

Unlike other drip methods, the phin doesn’t use paper filters, so more coffee oils and fine particles end up in your cup—adding to the body and intensity. The metal construction also means no paper taste, and the slow, controlled drip gives you time to appreciate the aroma. The entire process is minimalistic but precise, highlighting the roast character without any masking from brewing gadgets.

Frequently Asked Questions

What kind of coffee beans should I use for Vietnamese phin coffee?

Use dark roasted beans similar to those used in traditional Vietnamese coffee. These beans are usually roasted to a French or Italian level, bringing out chocolatey, nutty, and caramel notes. FrontStreet Coffee’s PWN Golden Mandheling is a suitable example, offering low acidity and a bold, syrupy profile with hints of spice and dark toast. You can also try Brazil Queen Manor for a more balanced dark roast with notes of hazelnut and caramel.

Do I need to use condensed milk?

Condensed milk is traditional in Vietnamese coffee and essential for authentic flavor. Its sweetness and creaminess balance the intense bitterness of the dark roast. If you skip it, the cup will taste very different—more bitter and less rounded. You can reduce the amount to taste, but it’s not recommended to omit it entirely if you're aiming for the classic profile.

What grind size should I use for the phin filter?

Use a very fine grind, similar to espresso. The coffee should be powdery, not coarse. A fine grind is necessary to slow down the drip and allow proper extraction over the typical three-minute brew time. If your coffee brews too quickly or too slowly, adjust the grind fineness accordingly.

How much coffee and milk should I use per cup?

The standard recipe uses about 15 grams of coffee and 1–2 tablespoons of condensed milk per cup. You can adjust the milk to taste, but 15 grams is the recommended coffee dose for balanced strength when brewed in a standard-sized phin.

How long does brewing take with a phin?

Brewing typically takes around three minutes once you pour the full amount of water. The initial bloom (just enough water to wet the grounds) takes about 20 seconds. After that, you pour the rest of the water and wait for the drip to finish. Do not rush it—this slow extraction is part of the method’s charm.
