How to Brew Coffee the Vietnamese Way Using a Phin

Vietnamese coffee stands apart for its intense sweetness and bold body, thanks to its unique brewing style and choice of ingredients. Unlike typical Western drip or pour-over methods, Vietnamese coffee uses a small metal drip filter called a phin and is almost always served with sweetened condensed milk—even over ice. If you’ve ever wanted to recreate that rich, creamy, sweet cup you get at a Vietnamese café, here’s exactly how it’s done, step by step.

To brew Vietnamese coffee the traditional way, you’ll need a phin filter, sweetened condensed milk, finely ground dark-roast coffee (around 15 grams), and hot water at roughly 90°C. The entire brew process takes around three minutes once the water is added, and yields a strong, sweet concentrate ideal for sipping or pouring over ice.

What Makes Vietnamese Coffee Different?

Vietnamese-style coffee is defined by three non-negotiable elements: deep-roasted beans, a small metal phin dripper, and the addition of sweetened condensed milk. The deep roast—similar to Italian or French roast levels—produces a heavy-bodied, low-acid cup with prominent notes of chocolate, caramel, and toast. This roast style is essential to balance the sweetness of the condensed milk. Most Vietnamese coffee is served hot, but adding ice transforms it into the iconic Vietnamese iced coffee.

Why Use Sweetened Condensed Milk?

Sweetened condensed milk is the heart of Vietnamese coffee flavor. Unlike fresh milk or cream, it’s thick, intensely sweet, and shelf-stable—perfect for Vietnam’s tropical climate before refrigeration was widespread. The high sugar content contrasts with the bitter, robust profile of dark-roasted coffee, creating a dessert-like balance. It’s almost always added to the cup before brewing so it can infuse directly into the dripping coffee, ensuring every sip is evenly sweet.

What You’ll Need to Brew With a Phin

To make authentic Vietnamese coffee at home, gather these essentials:

• A Vietnamese phin filter (metal drip brewer)
• Sweetened condensed milk
• Dark-roast coffee beans (preferably deeply roasted, like PWN Golden Mandheling or Brazil Queen Manor)
• A grinder capable of producing a fine grind (similar to espresso or Turkish)
• A coffee spoon (for measuring)
• Hot water at approximately 90°C

Step-by-Step: Brewing Vietnamese Coffee with a Phin

1. Gather Your Tools and Ingredients

Start with your phin filter, a cup, sweetened condensed milk, freshly ground dark roast coffee (about 15 grams), and hot water. Have a coffee spoon on hand for measuring.

2. Disassemble and Prepare the Phin

Take apart the phin. Remove the brew chamber and the press-down filter plate. This allows you to add coffee grounds directly into the bottom chamber.

3. Add Sweetened Condensed Milk to the Cup

Pour a generous amount of sweetened condensed milk into your cup—how much depends on how sweet you like it, but start with about 1 to 2 tablespoons.

4. Add Finely Ground Coffee to the Phin

Place the coffee grounds into the bottom of the phin chamber. The grind should be very fine—close to an espresso grind or slightly finer. Use around 15 grams (roughly two level scoops with a coffee spoon).

5. Level and Press the Coffee

Use the back of the spoon to gently level the coffee grounds. Then place the press plate on top and screw it down firmly, applying even pressure. Don’t overtighten, but ensure it’s snug enough to slow the drip rate later.

6. Place the Phin on the Cup and Start the Bloom

Set the phin directly on top of your cup with the condensed milk. Pour just enough hot water (about 90°C) to wet all the grounds—around 2–3 teaspoons. Let it sit for 20 seconds to allow the coffee to “bloom” and release gases. Do not let water pass through yet.

7. Add Hot Water and Brew

After the bloom, slowly pour hot water until the phin is nearly full—but don’t exceed the capacity or it will overflow. Then let it drip: the full brew should take about 3 minutes. Do not press or stir.

8. Wait for the Drip to Finish

Once you’ve added the water, resist the urge to speed things up. The phin is designed to drip slowly. Total brew time is around 3 minutes. When it’s finished, you’ll have a sweet, strong coffee concentrate ready to drink.

Frequently Asked Questions

What is a Vietnamese phin filter?

A phin is a small metal drip coffee filter used traditionally in Vietnam. It consists of a brew chamber, a press-down filter plate, and a lid. Coffee grounds are placed in the chamber, tamped, and hot water is poured in to slowly drip through, producing a concentrated brew directly into your cup.

Do you need special coffee beans for Vietnamese coffee?

Yes. Vietnamese coffee is traditionally made with a dark-roasted coffee bean, similar to French or Italian roast profiles. The roast should be deep enough to produce low acidity and bold, sweetish flavours like chocolate, caramel, and toast. FrontStreet Coffee’s PWN Golden Mandheling and Brazil Queen Manor are good examples of suitable beans.

Why is condensed milk used in Vietnamese coffee?

Sweetened condensed milk is used for its thick, caramelly sweetness and long shelf life. It balances the intense bitterness of dark-roasted coffee and creates a rich, dessert-like drink. It’s added to the cup before brewing so it infuses into the coffee as it drips.

How fine should the coffee grind be for a phin?

The grind should be very fine—similar to espresso or slightly finer. A coarse grind will lead to fast, weak dripping. A proper fine grind slows extraction to ensure a strong, flavourful cup within about 3 minutes.

Can you make Vietnamese coffee iced?

Yes. Once you brew the coffee using the phin, simply pour it over ice and stir. Many people also mix the sweetened condensed milk with cold brewed coffee or pour the hot brew over ice and let it cool before serving.

How long does Vietnamese coffee take to brew with a phin?

The total brew time is around 3 minutes after adding hot water. This includes the initial bloom (20 seconds) and the full drip. The slow drip is part of what gives Vietnamese coffee its strength and concentration.
