How to Brew Vietnamese Ultra-Fine Coffee Using a Drip Filter

If you’ve ever craved that rich, sweet Vietnamese coffee with thick crema and the perfect balance of bitter and creamy—but weren’t sure how to make it at home—this is your guide. The traditional Vietnamese method using ultra-fine coffee grounds and a metal drip filter delivers bold, syrupy results every time. Here’s how to get it right without guessing.

The classic Vietnamese drip coffee method uses 30g of ultra-fine coffee, a metal drip filter (phin or “”), plus sweetened condensed milk and sugar. Total brew time is around 10 minutes. You control strength and sweetness by adjusting the amount of milk and sugar to taste.

What Is Vietnamese Ultra-Fine Coffee?

Vietnamese-style coffee typically uses a very finely ground roast—finer than espresso—to create a slow, heavy extraction. This grind allows for a dense, intense brew that pairs perfectly with sweetened condensed milk. The coffee is often dark roasted, contributing to its bold, slightly burnt flavor profile. The use of a metal drip filter, known locally as a (phonetic: “dī dī hú”), ensures a slow, controlled drip that builds layers of flavor.

Why Use a Metal Drip Filter?

The metal drip filter, or , is essential for the Vietnamese coffee experience. Unlike paper filters, it lets more coffee oils and fine particles through, enhancing body and intensity. Its small chamber and slow drip rate allow for full extraction even with ultra-fine grinds. The design also makes it easy to brew a single serving directly into your cup, maintaining heat throughout the process.

Step-by-Step: Brewing Vietnamese Coffee with a Drip Filter

Here’s the classic method using 30g of ultra-fine coffee:

• Preheat your tools: Before brewing, rinse your coffee cup and the drip filter with hot water to maintain temperature.
• Add coffee: Place 30g of ultra-fine coffee grounds into the drip filter. Do not tamp—just level the grounds gently. Secure the filter’s lid.
• Brew with boiling water: Slowly pour just enough boiling water to wet the grounds, then fill the filter to the top. Place the drip filter on top of your cup.
• Collect the coffee: Let the coffee drip slowly into your cup. For best results, place your receiving cup in a bowl of hot water to keep it warm.
• Add condiments: Stir in sweetened condensed milk and sugar to your taste. For iced coffee, add a few ice cubes after brewing.

The entire process takes about 10 minutes. Don’t rush it—the slow drip is part of what gives this coffee its deep, layered flavor.

Vietnamese coffee made this way is typically very strong, sweet, and creamy due to the condensed milk. The ultra-fine grind and slow extraction produce a thick, almost syrupy brew with a heavy body and intense roast character. You can adjust the amount of condensed milk and sugar to suit your preference—from a lightly sweetened version to a thick, dessert-like coffee.
