How to Brew Vietnamese Coffee with a Phin

The phin is a small metal drip filter and a daily ritual. No pressure, no gadgets — just ground coffee, hot water, and about five unhurried minutes.

What is a phin?

A cup that asks you to slow down

Cà phê phin — “phin coffee” — is the everyday way coffee is brewed across Việt Nam. The phin itself is a simple four-piece metal filter: a base plate, a brewing chamber, a gravity insert that sits on the grounds, and a lid. It brews one strong cup at a time, drip by drip, with nothing but gravity.

That slowness is the feature, not a flaw. While the phin drips you wait — and that small pause is half of why Vietnamese coffee feels the way it does. Here is how to do it well.

Before you start

What you’ll need

A phin filter — the classic 4-piece Vietnamese drip filter.
Ground coffee — about 3 tablespoons, ground medium-coarse. Robusta is the traditional choice for its bold, low-acid body.
Hot water — 195–205°F, just off a full boil.
A cup or heatproof glass to brew into.
Optional: sweetened condensed milk and ice, if you’re heading toward cà phê sữa đá.

Phin at a glance

Grind: Medium-coarse
Coffee: ~3 tbsp (about 20 g)
Water temp: 195–205°F
Bloom: ~1:2 coffee–to–water
Water volume: ~½ cup (100–120 ml)
Drip time: 4–5 minutes

The method

Brew it in five steps

Total time is about seven minutes, most of it spent watching the drip.

Set up your phin

Set the phin filter on top of your cup or glass. Add about 3 tablespoons of medium-coarse ground coffee to the brew chamber, give it a gentle shake to level the bed, and rest the gravity insert on top.
Bloom the grounds

Pour in just enough hot water (195–205°F) to saturate the grounds — roughly twice the volume of the coffee, a 1:2 bloom. Wait 30–45 seconds while the grounds swell and release gas. This is the step most people skip, and it is the one that makes the cup taste complete.
Fill and cap

Top up the phin with hot water to about half a cup (100–120 ml) for a strong single serving. Set the lid on top to hold the heat and let the drip begin.
Let it drip

A good phin drips slow and steady for 4–5 minutes. If it races through, press the gravity insert down a little; if it stalls, loosen it a quarter turn. Patience here is the whole point of cà phê phin.
Serve it your way

Lift off the phin. Drink it black as cà phê đen, or pour the hot coffee over sweetened condensed milk and a glass of ice for cà phê sữa đá.

Tips for a better phin

Chase a steady drip. Aim for a slow, even fall of drops rather than a stream. Too fast and the cup tastes thin; too slow and it turns bitter.
Adjust with the insert, not the grind, first. Press it down to slow the flow, lift it slightly to speed it up. Only change your grind if you can’t get there.
Preheat for a hotter cup. A splash of hot water in the cup and phin before you brew keeps the coffee from cooling too fast.
Go coarser than espresso. A medium-coarse grind lets water move through evenly; too fine and the phin clogs and stalls.

What to brew

The phin was made for robusta

A phin and a bold robusta are a natural pair. Robusta’s low acidity and heavy, chocolatey body stand up to the concentrated brew and to condensed milk. Our Robusta Vietnamese Brew is grown in Dak Lak and roasted for exactly this cup — but any of our roasts will drip beautifully.
