How to brew Vietnamese coffee with a phin

To brew Vietnamese coffee with a phin, add about 2–3 tablespoons of ground Robusta to the filter, pour a splash of just-off-the-boil water to let it bloom for 30 seconds, then fill the phin, press the lid down lightly, and let it drip into your cup for 4–5 minutes. Pour over condensed milk, stir, and you've made cà phê sữa. That's the whole thing - but a few small details make the difference between muddy and magic.

A phin is the little metal drip filter that makes Vietnamese coffee what it is. It's cheap, unbreakable, and needs no electricity - just a few minutes and a bit of patience. Here's how to get it right.

What you'll need

• A phin filter (it has four parts: base, chamber, press/gravity insert, and lid)

• Ground Vietnamese Robusta, ground medium-coarse - a bit coarser than espresso, like coarse sea salt

• Hot water, around 90–96°C (just off the boil)

• Sweetened condensed milk (optional but classic)

• A cup or glass, and ice if you want it cold

Everything except the water and ice comes in our No Regrets Horse kit, so you can start without hunting down parts.

Step by step

Add the coffee. Spoon 2–3 tablespoons (about 15–20 g) of ground Robusta into the phin chamber. Give it a gentle shake to level it, then set the press insert lightly on top - snug, not cranked down.

1. Bloom. Pour just enough hot water to wet the grounds (around 20 ml) and wait 30 seconds. You'll see the coffee puff up slightly as it releases gas. This step makes a noticeable difference.

2. Fill and brew. Top up the phin with hot water (around 80–100 ml) and put the lid on. Now wait. The coffee should drip slowly and steadily for 4–5 minutes.

3. Adjust if needed. Too fast and weak? Tighten the press a little or grind finer next time. Stalled and dripping too slowly? Loosen the press or grind coarser.

4. Serve. For cà phê sữa, drip onto 1–2 tablespoons of condensed milk and stir. For cà phê sữa đá, pour the whole thing over a glass of ice. For black (cà phê đen), skip the milk.

Quick troubleshooting

• Bitter or harsh: your water may be too hot, or the grind too fine. Let the kettle rest a minute; coarsen the grind.

• Watery or sour: grind finer, tighten the press, or use a touch more coffee.

• Dripping too fast: the press isn't seated, or the grind is too coarse.

Vietnamese coffee rewards a little experimentation - once you find your grind and ratio, it's the same satisfying ritual every morning.
