⏳ Vietnamese Phin Brew Guide
Slow-drip, condensed-milk-sweetened, and unmistakably bold
Vietnamese coffee is brewed through a small metal phin filter that sits directly on top of the serving glass, using nothing but gravity to draw hot water through the grounds over several unhurried minutes. The result is a concentrated, syrupy cup traditionally paired with sweetened condensed milk — served hot (cà phê sữa nóng) or, more commonly today, poured over ice (cà phê sữa đá).
Coffee
20g
freshly ground
Water
150ml
filtered
Temp
95°C
203°F
Grind
Medium-coarse
Like kosher salt — coarser than pour over. The phin's metal disc has wider holes than a paper filter, so grounds this fine would clog it or overflow the chamber; too coarse and the drip finishes in seconds instead of minutes.

Set Up
For iced coffee (cà phê sữa đá), spoon 1–2 tbsp of sweetened condensed milk into your serving glass first. Set the phin's brew chamber on top of the glass, add 20 g of grounds, and level them gently — don't pack them down.

Recipe Steps
1
Set Up 0:30
For iced coffee (cà phê sữa đá), spoon 1–2 tbsp of sweetened condensed milk into your serving glass first. Set the phin's brew chamber on top of the glass, add 20 g of grounds, and level them gently — don't pack them down.
2
Bloom 0:40
Set the perforated press plate on top of the grounds and turn gently until it sits flush. Pour about 30 ml of hot water over it to saturate the grounds evenly. Wait 30–40 seconds — you should see the water darken and a few bubbles rise.
3
Main Pour 0:20
Pour the remaining water to fill the chamber near the rim — about 120 ml total. Place the lid on top; it traps heat and slows evaporation so the drip stays hot for its full run.
4
Slow Drip 3:30
Let gravity do the rest, undisturbed. The full drip takes 3–5 minutes — resist stirring or pressing the plate, which would rush extraction and pull through bitterness. A slower, steadier drip is a sign of a good grind and even bed.
5
Stir & Serve 0:30
Once dripping slows to occasional drops, remove the phin and set it on its lid. Stir the concentrated coffee into the condensed milk until fully combined. Drink as-is while hot, or pour over a full glass of ice for the classic iced version.
Frequently Asked Questions
What grind size is right for a phin filter?
Medium-coarse — like kosher salt, noticeably coarser than pour over or drip. The phin's metal filter disc has larger holes than paper, so a fine grind clogs it and can overflow; too coarse and the water rushes through in under a minute instead of the ideal 3–5.
Why is Vietnamese coffee served with condensed milk?
Fresh dairy was scarce and hard to keep in Vietnam's climate during the coffee's French colonial-era origins, so shelf-stable sweetened condensed milk became the standard pairing. It also balances the bold, low-acid, often robusta-forward profile the phin produces — the sweetness and body complement the coffee rather than mask it.
What's the difference between cà phê sữa nóng and cà phê sữa đá?
They're the same brew, served two ways. Cà phê sữa nóng is hot: the phin drips straight into a glass with condensed milk. Cà phê sữa đá is iced: the same hot concentrate is stirred into the milk, then poured over ice. Iced is far more common today, especially outside Vietnam.
Do I need special coffee for a phin?
Traditionally, Vietnamese coffee uses dark-roasted robusta beans (sometimes blended with a little butter or flavoring during roasting), which gives it a bold, chocolatey, low-acid character. You can absolutely use a dark or medium-dark arabica roast at home — look for chocolate, nutty, or caramel tasting notes for the closest match to the traditional cup.
Why does Vietnamese coffee take so much longer to brew than drip coffee?
The phin relies purely on gravity with no assist from paper-filter capillary action or pump pressure, so the 3–5 minute drip is inherent to the method, not a mistake. That slow, full immersion-like contact time is exactly what builds the concentrated, syrupy body strong enough to stand up to condensed milk and ice without tasting watered down.
