What Is Vietnamese Drip Coffee (‘Drip Jin’)?

If you’ve ever ordered coffee in Vietnam and been told it’ll take ten minutes, you’re not just waiting for a barista—you’re waiting for a ritual. The drink behind the delay is called ‘drip jin’ , a uniquely Vietnamese way of brewing coffee that turns a simple cup into a slow, deliberate experience.

Vietnamese drip coffee, or ‘drip jin’, takes around 10 minutes to brew using a small metal drip filter called a phin, poured over a glass of sweetened condensed milk. The entire process—from setup to your first sip—is designed to unfold slowly, making patience part of the flavor.

The Origins of ‘Drip Jin’ in Vietnam

Vietnam’s relationship with coffee began 150 years ago, when French missionaries introduced coffee plants to the country. Over time, locals adapted European brewing methods to local tastes and resources—most notably, by embracing strong Robusta beans and sweetened condensed milk. This blending of techniques and ingredients gave rise to Vietnam’s distinctive coffee identity, of which ‘drip jin’ is a central tradition.

Why Does Drip Jin Take So Long?

The wait for a cup of drip jin is built into its brewing method. Unlike espresso machines or filtered drip pots, drip jin uses a small metal phin filter that sits atop a glass. Hot water is poured over medium to coarse ground coffee inside the phin, and the liquid drips slowly through—a process that can take up to ten minutes for a single cup. The long brew time extracts a bold, rich shot of coffee that balances the sweetness of the condensed milk it’s often mixed with.

How Drip Jin Is Actually Made

To prepare a traditional cup of drip jin, follow these steps:

• Place a phin filter—typically made of stainless steel or aluminum—on top of a heat-resistant glass, often a vintage-patterned glass tumbler.
• Add finely ground coffee (usually medium-fine to mimic traditional pressurized extraction) into the phin. A standard serving uses about 15–20 grams.
• Press down a perforated metal filter plate (often included with the phin) to tamp the grounds lightly.
• Pour a small amount of hot water (just off boil, around 90–96°C) to bloom the coffee, then fill the phin to the top.
• Let the coffee drip slowly into the glass below. The entire brew may take 8–10 minutes depending on grind size and water temperature.
• Once brewed, mix the strong black coffee with a layer of sweetened condensed milk sitting at the bottom of the glass. For black coffee, no straw is typically given; for the sweetened version, a straw is provided.

Some enthusiasts serve the glass in a bowl of hot water to keep the coffee warm during the long drip, especially in cooler climates or air-conditioned rooms.

Misconceptions and Patient Pleasure

There’s a common belief that drip jin is merely slow coffee. In truth, it’s a mindful ritual where the act of waiting becomes part of the enjoyment. Those who rush the process miss the point: the slow extraction, the layering of flavors, and the meditative pace are essential to appreciating what makes this style unique. Patience isn’t just advised—it’s required.

Frequently Asked Questions

What is ‘drip jin’ coffee?

‘Drip jin’ , also known as Vietnamese drip coffee, is a slow-brewed coffee made using a metal phin filter. It typically drips hot coffee into a glass of sweetened condensed milk over 8–10 minutes, creating a strong, sweet, and rich drink.

Why does it take 10 minutes to make drip jin?

Drip jin takes around 10 minutes to brew because it uses a small metal phin filter that allows coffee to drip slowly through medium to coarse grounds. The slow extraction process is integral to the flavor and texture of the final cup.

Do you use a coffee maker for drip jin?

No, drip jin is not made with a typical coffee maker. It is brewed using a small metal drip filter called a phin, which sits on top of a glass and lets the coffee drip through under gravity.

Is condensed milk always used in drip jin?

Condensed milk is commonly used in drip jin, especially in the sweetened version. However, black drip jin—without milk—is also popular, especially among those who prefer their coffee unsweetened.

What grind size is used for drip jin?

The typical grind size for drip jin is medium to medium-fine, similar to what you’d use for a pour-over or espresso, to ensure proper extraction through the phin filter within the 8–10 minute brew window.

Can I make drip jin without a phin?

Technically, you can try alternatives, but the traditional drip jin experience relies on the phin filter’s design to control flow rate and extraction. Without a phin, the result and timing will differ significantly.
