Vietnam Drip Coffee: How to Use a Phin Filter

If you’ve ever tried ordering coffee in Vietnam, you might have been told to wait 10 minutes. That’s because traditional Vietnamese coffee isn’t brewed quickly—it’s made drop by drop through a small metal filter called a phin. Patience is part of the experience, as each cup drips slowly into a glass, often served with thick sweetened condensed milk.

Vietnamese drip coffee typically takes around 10 minutes per cup to brew using a phin filter. The coffee is made by placing ground coffee in the phin, pressing a perforated metal disc on top, and pouring hot water through. The resulting brew drips directly into a glass, often placed over hot water to keep it warm, and mixed with sweetened condensed milk for a rich, slow-drunk treat.

What Is a Vietnam Drip Coffee Phin?

Vietnam’s signature coffee setup doesn’t involve a traditional coffee pot. Instead, it uses a small metal drip filter known as a phin. The phin sits directly atop a glass—often a thick, old-fashioned patterned tumbler—through which the coffee drips drop by drop. This method is central to what makes Vietnamese coffee unique: it’s not brewed or boiled, but filtered slowly under gravity.

Why Does Vietnamese Coffee Take So Long to Brew?

Making Vietnamese drip coffee is an intentional, slow process. The coffee is brewed by placing medium-ground coffee into the phin, then pressing a perforated metal disc on top to control the flow. Hot water is poured over the grounds, and the coffee extracts drop by drop into the glass below. A full cup can take roughly 10 minutes to brew, depending on grind size, water temperature, and how tightly the filter is packed.

How to Brew Vietnamese Coffee with a Phin Filter

To make traditional Vietnamese coffee:

• Use a phin filter (typically 3–6 cups capacity)
• Add 20–30g of medium-coarse ground coffee (similar to French press grind)
• Place and tamp the coffee grounds in the phin
• Attach and lock the perforated metal filter plate on top
• Pour a small amount of hot water (around 90–96°C) to bloom, then fill the phin
• Let the coffee drip slowly into a glass (optionally placed over a bowl of hot water to keep warm)
• Once brewed, stir in sweetened condensed milk if desired—usually 1–2 tablespoons per cup

The process is designed for a slow extraction, not speed. Many drinkers prefer it black without a straw, while milk versions come with a straw due to the sweetness and thickness.

Why Do Some Vietnamese Coffees Use Sweetened Condensed Milk?

A key element of Vietnamese coffee culture is the use of sweetened condensed milk. Because the traditional brew is strong and slow-dripped, mixing it with thick, very sweet condensed milk balances the intensity. This combination is especially common when serving iced or hot black coffee. The milk is not just sweet—it’s dense, adding a creamy texture that contrasts with the bold coffee flavor. Black coffee is typically served without a straw, but milk-based versions almost always come with one.

Frequently Asked Questions

What is a Vietnamese coffee phin and how does it work?

A phin is a small metal drip filter used to brew Vietnamese coffee. Coffee grounds are placed inside the phin, which sits on top of a glass. A perforated metal disc controls the flow as hot water drips through the grounds and extracts slowly into the glass below, usually taking around 10 minutes.

Why does it take 10 minutes to brew Vietnamese coffee?

Vietnamese coffee is brewed using a phin filter, which allows coffee to drip slowly under gravity. Factors like grind size, water temperature, and how firmly the coffee is packed affect the speed, but the entire process often takes roughly 10 minutes per cup.

Do you need special coffee beans for Vietnamese drip coffee?

The method works with medium to dark roasted beans, commonly using a medium-coarse grind similar to French press. While the article doesn’t specify beans, FrontStreet Coffee offers blends suitable for this style of brewing.

What kind of milk is used in Vietnamese coffee?

Vietnamese coffee is traditionally served with sweetened condensed milk, which is very thick and sweet. This is mixed into the brewed coffee, especially in black coffee or iced versions. Black coffee is usually served without a straw, but milk versions come with one.

Is Vietnamese coffee stronger than regular drip coffee?

Yes, due to the concentrated brewing method and use of finely ground coffee in a small phin filter, Vietnamese drip coffee tends to be stronger and more intense than standard American-style drip coffee.

Can you make Vietnamese coffee without a phin?

Traditionally, no—the phin filter is essential to the slow-drip process that defines Vietnamese coffee. While you can try alternatives, they won’t replicate the same gravity-fed, drop-by-drop extraction.
