How to Brew Vietnamese-Style Drip Coffee with a Phin

If you’ve ever sipped a thick, sweet, strong Vietnamese coffee and wondered how it’s made — the answer lies in the phin, deep-roasted beans, and a pour-over method unique to Vietnam. Whether you want the classic hot version or the refreshing iced variation, making it right means understanding the tools, technique, and tradition.

To brew Vietnamese-style coffee, you’ll need a phin dripper, sweetened condensed milk, finely ground dark roast coffee (about 15 grams), and hot water near 90°C. The entire brew takes around 3 minutes once water hits the coffee bed.

What Is Vietnamese Drip Coffee?

Vietnamese coffee culture is distinct. The style relies on dark-roasted beans brewed through a small metal drip filter called a phin (or “drip filter” in local terms). Unlike Western pour-overs, Vietnamese drip coffee is almost always prepared with sweetened condensed milk — a defining feature. When served over ice, it becomes the iconic Vietnamese iced coffee known globally for its bold sweetness and intensity.

Why Add Sweetened Condensed Milk?

Vietnam’s coffee tradition developed with limited access to fresh milk, so sweetened condensed milk became the standard dairy addition. Its thick texture and high sugar content balance the intense bitterness of dark-roast coffee, resulting in a rich, dessert-like cup. The combination is now a hallmark of Vietnamese coffee worldwide.

How to Use a Vietnamese Phin Filter (Step-by-Step)

Here’s the exact method for brewing a single serving of Vietnamese drip coffee using a phin, based on the original instructions:

• 1. Gather Your Tools: You’ll need a Vietnamese phin filter, sweetened condensed milk, finely ground dark roast coffee (preferably locally sourced in Vietnam), and a coffee spoon.
• 2. Disassemble the Phin: Take apart the filter and remove the press plate (also called the spreader or filter top).
• 3. Add Condensed Milk: Pour a small amount of sweetened condensed milk into your cup — adjust to taste. Typically around 1 to 2 tablespoons.
• 4. Add Coffee Grounds: Add freshly ground dark roast coffee directly into the cup. The grind should be very fine, similar to table salt or slightly finer.
• 5. Measure the Coffee: Use approximately 15 grams of coffee. A common estimate is two coffee scoops using a standard spoon.
• 6. Level and Press: Even out the coffee bed with your spoon or finger. Place the press plate on top and gently twist to compact the grounds evenly — not too tight, not too loose.
• 7. Assemble and Bloom: Lock the press plate into the base of the phin. Place the phin filter directly onto your cup. Pour just enough hot water (not boiling, ideally around 90°C) to saturate all the grounds — just enough to get them wet, without draining through yet. This is called the bloom, and you should let it sit for around 20 seconds.
• 8. Add Remaining Water: Slowly pour the rest of the hot water (around 100–150ml total, depending on your cup) into the phin until full. Do not overflow.
• 9. Wait for the Drip: Let the coffee brew slowly. This usually takes around 3 minutes for the full extraction. Do not stir or press during this time.
• 10. Serve: Once the dripping stops, your coffee is ready. Stir to mix the condensed milk. For iced coffee, pour the brewed coffee over ice.

What Grind Size Works Best for a Phin?

The ideal grind size for a Vietnamese phin is very fine — similar to espresso or slightly finer than table salt. A fine grind slows down the extraction to allow proper dripping through the small holes in the filter and ensures enough resistance for proper flavor development.

Can You Use Other Coffee Beans?

Traditional Vietnamese coffee uses locally roasted beans that are dark roasted — often to the point of heavy body, low acidity, and bold flavors like chocolate, caramel, and toast. While the recipe originated with local beans, you can replicate the style using any high-quality dark roast. Beans with notes of dark chocolate, nuts, or caramel complement the condensed milk well.

What’s the Best Ratio of Coffee to Condensed Milk?

There is no strict rule, but a typical starting point is around 15g of coffee and 1–2 tablespoons of condensed milk. Adjust to your taste — more milk for a sweeter, milder drink, less for a stronger, bitter edge.

Brewing Vietnamese Coffee Over Ice

To make iced Vietnamese coffee, follow the same steps but pour the hot brewed coffee directly over a glass filled with ice. The ice dilutes the concentrate slightly while cooling it instantly, resulting in a refreshing yet still intense coffee experience.

Is Vietnamese Coffee Strong?

Yes. Due to the fine grind, slow drip, and use of dark roast coffee, the brew is both concentrated and intense. Combined with condensed milk, it delivers a thick, sweet, and powerful coffee flavor in every sip.

Frequently Asked Questions

What is a Vietnamese phin coffee filter?

A phin is a small metal drip filter used to brew single servings of Vietnamese coffee. It consists of a base, a brewing chamber, a press plate, and a lid. It allows coffee to drip slowly through finely ground coffee, producing a strong, concentrated brew.

Do you need special coffee beans for Vietnamese coffee?

No, you don’t need special beans, but traditionally Vietnamese coffee uses dark-roasted beans with low acidity and bold flavors like chocolate and caramel. You can use any dark roast, including PWN Golden Mandheling or other deep-roasted coffees, to achieve a similar profile.

How fine should the coffee grind be for a phin?

The grind should be very fine—similar to espresso or table salt. A fine grind is essential to slow down the water flow through the phin and ensure proper extraction and flavor.

How much coffee do you use in a phin?

Most recipes use about 15 grams of coffee, typically equivalent to two level scoops with a standard coffee spoon. Adjust based on your phin size and taste preference.

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

Brewing time is around 3 minutes once water is added, including the initial 20-second bloom period. Total time may vary slightly based on grind size and water temperature.

Can you make Vietnamese coffee with milk instead of condensed milk?

Yes, but it won’t taste authentic. Sweetened condensed milk is a key ingredient in traditional Vietnamese coffee. Regular milk or cream lacks the same thickness and sweetness, altering the flavor profile significantly.
