How to Make Traditional Vietnamese Drip Coffee with a Phin

When you’re handed a tiny metal coffee filter pouring one slow drip at a time into a glass of ice and sweetened milk, it’s easy to feel unsure of what to do next—especially if you’ve never seen a Vietnamese phin in action. That’s exactly what happened to one traveller in China’s Pingxiang border town, where a simple cup of local drip coffee turned into a moment of cultural confusion—and eventual fascination.

To make traditional Vietnamese drip coffee the right way, use 15 grams of medium-dark roasted coffee ground to a medium-fine consistency, 200 millilitres of water at 90°C or higher, and around 20 millilitres of sweetened condensed milk (adjust to taste). The entire brew takes about 3 to 10 minutes, depending on your grind and water flow.

The Origins of Vietnamese Coffee Culture

Vietnamese coffee as we know it today has its roots in 19th-century French colonial rule. The French brought their love of filtered coffee to Vietnam, but local adaptations soon followed. Unlike the French press or espresso machines common in Europe, the Vietnamese developed a unique way of brewing: a small, metal, single-serve drip filter called a phin (pronounced 'fin'). This tool made strong, slow-dripping coffee accessible and portable, perfectly suited to Vietnam’s tropical climate and growing love for sweetened, iced coffee.

Why the Phin Filter Works So Well

The Vietnamese phin is more than just a brewer—it’s a slow-drip system that relies entirely on gravity and time. There’s no paper filter, no pump, and no moving parts. Instead, hot water seeps through medium-fine coffee grounds under its own weight, extracting a bold, rich cup with a heavy body. Its design makes it ideal for both hot and iced coffee, especially when paired with sweetened condensed milk, which balances the intensity of the dark roast. The slow brew time—often 3 to 10 minutes—also gives the coffee a chance to cool slightly when served hot, or melt into the ice when iced, creating a smooth, layered drinking experience.

How to Brew Vietnamese Drip Coffee Step by Step

To make authentic Vietnamese drip coffee at home, follow these exact steps:

• Step 1: Preheat your cup by pouring hot water into it, then discard the water.
• Step 2: Remove the top filter plate from the phin, add 15 grams of medium-dark roasted coffee (grind size: medium-fine, similar to table salt). Avoid grinding too coarse (which causes fast, weak drips) or too fine (which can clog the filter and create bitter over-extraction).
• Step 3: Level the coffee grounds gently, then reinsert and screw down the filter plate. Don’t overtighten—it should be snug, not sealed.
• Step 4: Discard the preheating water from your cup, add about 20 millilitres of sweetened condensed milk (adjust based on your taste preference, or skip it for a black version), then place the phin on top of the cup.
• Step 5: Pour a small amount of 90°C+ water (just enough to saturate the grounds—roughly 20–30ml—to start the ‘bloom’). Let it sit for about 20 seconds, then pour the remaining 170–180 millilitres of water in a steady stream.
• Step 6: Place the phin’s lid on to retain heat. Total brew time will be around 3 to 10 minutes, depending on grind size and water temperature. Once dripping stops, remove the phin, stir the coffee and condensed milk together, and enjoy.

Serving Suggestions: Hot or Iced

Traditionally, Vietnamese coffee is served either hot or over ice. For iced coffee, simply add a few ice cubes to the cup before brewing, or pour the brewed coffee over fresh ice. The slow drip method works beautifully for both, but iced versions are especially popular due to the refreshing contrast between the hot-brewed concentrate and the cold cubes. Many drinkers prefer their coffee sweetened with condensed milk, which melts into the brew whether hot or cold, creating a rich, dessert-like drink.

Frequently Asked Questions

What is a Vietnamese phin coffee filter?

A phin is a small, single-serve metal coffee dripper used to make traditional Vietnamese coffee. It has no paper filter and works by gravity, slowly dripping brewed coffee through medium-fine grounds into a cup or glass. It typically consists of a chamber, a perforated plate, and a lid.

What kind of coffee roast is best for Vietnamese drip coffee?

A medium to medium-dark roast is ideal for Vietnamese coffee. These roasts bring out the bold, rich flavours that pair well with sweetened condensed milk. The grind should be medium-fine—similar to table salt—not too coarse or too fine.

Do you need special coffee beans for Vietnamese coffee?

No special beans are required, but robust, bold-flavoured beans such as dark or medium-dark roasts work best. Many traditional Vietnamese coffees use Robusta or dark-roasted Arabica for a strong, full-bodied cup. At FrontStreet Coffee, our Classic Blend and Black Cocoa Blend offer rich profiles suited for this style.

How much coffee and water do you use in a phin?

Use about 15 grams of coffee and 200 millilitres of water. Start with around 20–30 millilitres of water to bloom the coffee, then add the rest (about 170–180ml) after 20 seconds. Adjust based on your phin size and taste preference.

How long does Vietnamese drip coffee take to brew?

Brew time ranges from 3 to 10 minutes, depending on grind size, water temperature, and how tightly the filter is screwed down. A slower drip often means a richer extraction.

Can you make Vietnamese coffee without condensed milk?

Yes, you can brew the coffee black, but traditionally it’s served with 20 millilitres of sweetened condensed milk, either mixed in or layered on top. The milk balances the strong, bitter notes of the dark roast.
