To make Vietnamese coffee at home, brew a small concentrated coffee in a phin, then serve it black, with sweetened condensed milk, or over ice. For a small phin that holds the dose comfortably, begin with 20g coffee and 100g water. Add about 20g condensed milk only if you want a milk version.
Choose the finished drink before buying equipment. A hot black cup needs little beyond a phin and kettle; an iced milk drink also needs a heatproof brewing cup, a larger serving glass and plenty of ice. The complete Vietnamese coffee guide explains how these drinks fit together.
Choose your first drink
| What you want | Make this | Main adjustment |
|---|---|---|
| A small black coffee | Ca phe den | Taste before diluting |
| A sweet hot drink | Coffee with condensed milk | Start with less milk |
| A cold, sweet coffee | Ca phe sua da | Brew strong enough for ice |
| A cold black drink | Ca phe den da | Add ice after checking strength |
There is no obligation to start with the sweetest version. If you normally drink black coffee, keep the milk separate so you can compare the base and the finished drink.
Set out a compact brewing kit
Use a phin with a stable base, a kettle, coffee, a heatproof cup and a spoon. Scales help you repeat the recipe. Check that the phin sits safely on your cup before pouring; narrow glasses and very wide mugs can be awkward matches.
Pre-ground coffee is a reasonable first purchase if it is intended for phin brewing. Buying a grinder immediately is unnecessary. Our bean guide explains robusta, arabica and blends; the filter overview helps you choose a size.
Brew the coffee base
- Rinse the phin and cup with hot water, then empty the cup.
- Add 20g medium-fine coffee and gently level it. Fit the insert without pressing hard.
- Add 20g hot water, wetting the bed evenly. Wait about 30 seconds.
- Add another 80g water, or enough to reach the total without overfilling your chamber. Fit the lid.
- Let the coffee drip into the cup. Several minutes is normal, but judge the flow and taste rather than insisting on one timer reading.
- Remove the filter to a heatproof drip tray and stir the coffee.
Start around 92-96C if you have temperature control. For a dark roast that tastes harsh, try slightly cooler water on the next brew. Manufacturers may specify different ratios for their filters; use their recipe when this starting dose does not fit. The phin technique guide gives the detailed dial-in process.
Finish it hot or iced
For black coffee, taste a cooled spoonful and add hot water in small amounts if the concentration is uncomfortable. Do not confuse a strong brew with a requirement to drink it undiluted.
For hot milk coffee, stir in 15-20g sweetened condensed milk, taste, then add more if needed. An initial smaller amount leaves room to adjust. Use the condensed milk guide to compare ingredients and substitutions.
For iced coffee, stir coffee and condensed milk while warm, then pour over a separate glass of ice. The coffee should taste concentrated before dilution. See the iced recipe for a complete serving method and the ratio guide if it becomes watery.
Make your second cup better
Keep a short note: coffee, dose, water, grind, drip time and what you would change. If the first cup is weak, reduce the brew water slightly or grind a little finer. If it is harsh and drying, try a coarser grind or lower temperature. Change one thing, rather than simultaneously changing coffee, milk and water.
A fast-dripping phin and a slow-dripping phin need different fixes. Adding more milk can hide the problem without improving the coffee base.
When you do not own a phin
A moka pot, cafetiere or espresso machine can produce a useful base for a Vietnamese-style milk drink. Follow that brewer’s own instructions and adjust the milk to the output. The texture and extraction will differ, so present it as an adaptation.
Our French press method is useful when you already own a cafetiere. Begin with what fits your kitchen, learn one repeatable drink, and buy additional equipment only when it solves a real inconvenience.
Frequently asked questions
Can I use coffee I already own?
Yes. Choose a grind that lets your phin drip steadily. Medium-dark coffee is a practical starting point for milk drinks, but Vietnamese origin is not essential to practise the method.
Should I add milk before brewing?
Condensed milk can go in the cup first or be stirred in after brewing. Mixing thoroughly before adding ice matters more than the layering.
Can I brew without scales?
You can use the same spoon and water mark each time, but weighing once makes adjustments much easier. Spoon volume varies with the grind and how tightly it is filled.
Do I need an espresso machine?
No. A phin needs hot water and gravity. Espresso can be an alternative coffee base, but is a different brewing method.
