How to Make Vietnamese Drip Coffee with a Phin Filter

If you’ve ever ordered Vietnamese coffee and been told to wait ten minutes, you’re not just waiting for service—you’re waiting for a slow, deliberate brew that defines the country’s coffee culture. The iconic Vietnamese drip coffee, often called 'drip gold' or '', isn’t just a drink. It’s an experience built around a unique metal filter, a steady drip, and often, sweetened condensed milk.

To make authentic Vietnamese drip coffee the traditional way, you’ll need a phin filter, hot water (around 90°C), coffee grounds, and—if you want it sweet—sweetened condensed milk. The entire brew typically takes three to ten minutes, depending on grind and pressure. That slow drip is part of the charm.

What Is a ‘Drip Gold’ Coffee?

Vietnamese coffee, locally referred to as '' (drip gold), is traditionally brewed using a small metal drip filter called a phin. This method produces a strong, slow-dripping cup of coffee, often served with sweetened condensed milk. The phin sits directly atop a glass, allowing the coffee to drip one drop at a time—often taking several minutes. The name 'drip gold' reflects both the golden brew and the precious patience required to enjoy it.

Why Does Vietnamese Coffee Take So Long to Brew?

The extended brew time—anywhere from three to ten minutes—is due to the design of the phin filter and the grind size. Unlike espresso machines or pour-over setups that push water through quickly, the phin relies solely on gravity. A properly tamped coffee bed and fine to medium-fine grind slow the flow rate down, extracting flavour gradually. Many Vietnamese drinkers deliberately let it take longer to savour the ritual.

What You Need to Brew Vietnamese Coffee

• A phin filter (metal drip brewer with a press plate)
• A transparent coffee cup or glass (essential to watch the dripping)
• Fine to medium-fine coffee grounds
• Hot water at approximately 90°C
• A small pouring kettle (with a narrow spout for control)
• Sweetened condensed milk (optional, but traditional)

Step-by-Step: How to Brew Vietnamese Drip Coffee

1. Add Condensed Milk (Optional): If you're making sweetened coffee, add your desired amount of sweetened condensed milk to the bottom of your glass. This is a signature feature of Vietnamese iced or hot milk coffee.
2. Load the Phin: Place coffee grounds into the phin filter and shake gently to level them. Do not tamp yet.
3. Tamp the Coffee: Screw down the press plate to gently compress the coffee. The goal is a brew time of about three minutes. Adjust the tightness accordingly—if it drips too fast, tighten more.
4. Bloom the Coffee (Optional but Recommended): Pour a small amount of hot water (not enough to drip) over the coffee grounds to wet them fully. Let it sit for about 20 seconds. This step, known as the bloom, helps release gases and improve extraction.
5. Pour Hot Water: After blooming, fill the phin with about 90°C water until full. Place the lid on the phin to help maintain heat.
6. Wait for the Drip: Allow the coffee to slowly drip into the cup. Total brew time should be around three to ten minutes depending on your grind and tamp pressure.

How to Serve and Drink Vietnamese Coffee

Once brewed, stir the concentrated coffee with the condensed milk until fully mixed. For iced versions, pour the mixture over ice. Traditionally, black coffee is served without a straw, while milk coffee comes with a straw. Sip slowly—the slow brew process is meant to be savoured, not rushed.

Frequently Asked Questions

What is a phin filter and where does it come from?

A phin filter is a small, single-serving metal drip brewer traditionally used in Vietnam. It consists of a chamber for coffee grounds, a perforated plate, and a drip spout. It was introduced during the French colonial period in the 19th century and has since become a cultural icon in Vietnamese coffee preparation.

How long should Vietnamese coffee take to brew?

A properly brewed cup of Vietnamese coffee using a phin typically takes between three to ten minutes. The exact time depends on factors like grind size, coffee bed tamping, and water temperature. Slower drips generally produce stronger, more extracted coffee.

Do you need to use condensed milk in Vietnamese coffee?

No, condensed milk is optional but traditional. Many Vietnamese coffee drinkers use sweetened condensed milk, especially for iced or hot milk coffee. For black coffee, no milk is added, and straws are usually not provided.

What grind size should I use for a Vietnamese phin filter?

Use a fine to medium-fine grind, similar to table salt or slightly finer than pour-over grind. The grind affects brew time—finer grinds slow the drip and increase extraction time, while coarser grinds may cause it to drip too quickly.

Can I make Vietnamese coffee with other brew methods?

Authentic Vietnamese drip coffee relies on the phin filter for its signature slow-drip character. While you can replicate the flavour with other methods, the experience and brewing pace are unique to the phin’s gravity-fed design.
