How to Use a Vietnamese Phin Drip Coffee Maker

You’ve seen the tiny metal cup sitting atop a glass of thick, sweet coffee—but how exactly does the Vietnamese phin drip work? Unlike a French press or pour-over, the phin relies on gravity and precision to extract rich, bold coffee straight into your cup. Here’s how to get it right every time.

To make traditional Vietnamese coffee with a phin, you’ll need: a phin dripper, very finely ground dark roast coffee (around 15 grams), sweetened condensed milk, and hot water at roughly 90°C. Total brew time is around 3 minutes after blooming. That’s the straightforward formula—but getting each step precise makes all the difference.

What Is a Vietnamese Phin and Why It’s Different

Vietnamese coffee culture is defined by a few non-negotiables: ultra-dark roasted beans, sweetened condensed milk, and brewing through a small metal filter called a phin. The result is a thick, bold, and intensely sweet cup—often served hot, but just as popular over ice. Unlike drip machines or pour-overs, the phin uses no paper filter, and gravity does the work. That means every element—from grind size to water pour—affects the final cup.

Why Vietnamese Coffee Uses Deep Roast and Condensed Milk

The style is built around strong contrasts: the intense bitterness of a dark roast balanced by creamy, thick sweetened condensed milk. Vietnamese coffee beans are typically roasted well into the second crack, producing notes of dark chocolate, caramel, and toast. The deep roast reduces acidity and enhances body. Adding condensed milk isn’t just common—it’s essential to the profile. For a chilled version, just pour the brewed coffee over ice.

What You’ll Need to Brew With a Phin

• Vietnamese phin drip filter (metal)
• Sweetened condensed milk
• Finely ground dark roast coffee (ideally 15g)
• Coffee spoon (for measuring)
• Coffee cup or glass (holds at least 12–15 oz)
• Hot water (approximately 90°C / 194°F)

Step-by-Step: Brewing Vietnamese Coffee With a Phin

1. Disassemble and Prepare the Phin

Start by taking the phin apart. Remove the press plate (also called the filter plate or spreader) and set it aside. This lets you add coffee directly into the base.

2. Add Condensed Milk to Your Cup

Pour a small amount of sweetened condensed milk into the bottom of your cup—how much depends on your taste, but start with about 1 to 2 tablespoons for a balanced drink.

3. Add Coffee Grounds to the Phin

Scoop approximately 15 grams of finely ground dark roast coffee into the phin’s base. The grind should be very fine—close to espresso grind—or even slightly finer. A coffee spoon is about right for estimating 15g, though a scale gives the best accuracy.

4. Level and Press the Coffee

Use the back of the spoon to gently level the grounds. Then place the press plate on top and twist it down until it’s snug against the coffee. Don’t force it too hard—you want even pressure, not a seal.

5. Place the Phin on the Cup and Start the Bloom

Set the assembled phin (with coffee inside) directly onto your cup. Pour just enough hot water (around 90°C) to wet all the grounds—roughly 2–3 teaspoons. This step is called the bloom, and it helps release gases for better extraction. Let it sit for about 20 seconds.

6. Pour the Rest of the Water

After the bloom, slowly pour hot water until the phin is full—usually around 100–150 ml depending on your cup size. Do not refill mid-brew; just pour once and let it drip through.

7. Wait for the Coffee to Drip Through

Now let the coffee brew undisturbed. Total brew time should be around 3 minutes from when you poured the full water. The slow drip is part of the experience—and the richness.

8. Stir and Serve

Once all the coffee has dripped through, remove the phin. Stir the concentrated coffee with the condensed milk until fully mixed. Serve hot, or pour over ice for a refreshing iced version.

Frequently Asked Questions

How much coffee do I use in a Vietnamese phin?

Use around 15 grams of finely ground dark roast coffee. A standard coffee spoon is a close estimate, but using a scale ensures consistency.

What grind size should I use for a phin?

The grind should be very fine—similar to espresso or slightly finer. A coarse grind will lead to under-extraction and slow, uneven dripping.

Do I need to bloom the coffee in a phin?

Yes. Blooming (pouring a small amount of hot water to wet all the grounds) for about 20 seconds improves extraction and flavor. Use around 2–3 teaspoons of water for the bloom.

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

Total brew time is around 3 minutes after the bloom. The slow drip is normal and contributes to the coffee’s body and strength.

Can I make iced Vietnamese coffee with a phin?

Yes. Brew the coffee hot using the phin as directed, then pour it over ice. The condensed milk is added to the cup first before brewing or mixed in afterward.

Why is my phin drip too slow or too fast?

A drip that’s too slow may be caused by too much coffee, overly fine grind, or pressing the plate too tightly. If it’s too fast, the grind may be too coarse or the coffee not pressed evenly.
