The phin is Vietnam's everyday coffee maker: a small metal filter that sits on your cup while hot water seeps through the grounds and drips down, one drop at a time. No electricity, no machine. But to get a cup that is rich and aromatic rather than harsh, a few simple principles matter.
What you need
- A phin, with four parts: the base plate, the chamber, the press (inner filter) and the lid. Aluminium phins are light and cheap; stainless steel holds heat better and lasts longer.
- 20–25 g of ground coffee (about 2 heaped tablespoons), ground medium to slightly coarse, like fine sea salt. 1021 Pre-Ground Coffee is ground to exactly this size.
- 100–120 ml of water just off the boil, rested for about 30 seconds (roughly 92–96 °C). Furiously boiling water tends to make coffee bitter and astringent.
- A glass or ceramic cup, plus condensed milk and ice if you like.
Step by step
- Warm up. Pour hot water through the phin and into the cup, then discard it. A warm phin keeps the brewing temperature steady from the first drop.
- Add coffee. Tip the coffee into the chamber and shake gently to level it. Set the press on top and push very lightly, just enough for it to sit flat. Pressing hard is the most common reason a phin clogs.
- Bloom. Pour about 20 ml of water, just enough to wet the grounds, and wait 30–45 seconds. Freshly roasted coffee will swell and bubble as it releases CO₂. This helps the water extract evenly.
- Fill. Pour the rest of the water almost to the top and put the lid on to hold the heat.
- Wait. It should drip steadily, about 1–2 drops per second, and finish in 4–6 minutes.
Tip: When it's done, turn the lid upside down on the table and rest the phin on it. It catches the last drips.
Too fast or too slow?
| What happens | Usual cause | Fix |
|---|---|---|
| Done in under 3 minutes; weak, sour cup | Grind too coarse, too little coffee, press too loose | Use 25 g and tighten the press slightly |
| Over 8 minutes or barely dripping; harsh, bitter cup | Grind too fine, pressed too hard, water too hot | Loosen the press, let the water rest 30 s, grind coarser |
| Grounds float up when you pour | Skipped the bloom, poured too hard | Always bloom; pour slowly in a circle |
Four classic ways to drink it
- Đen nóng: hot and black, to taste the bean itself.
- Đen đá: brew 20 g with only 80 ml of water for a stronger shot, sweeten if you like, and stir over ice.
- Nâu đá (cà phê sữa đá): put 1–2 tablespoons of condensed milk in the cup first, brew on top, stir, then pour over ice.
- Bạc xỉu: mostly milk, a little coffee. About 3 parts condensed and fresh milk to 1 part coffee.
Robusta or Arabica for the phin?
Robusta gives the bold, heavy, bittersweet body of traditional phin coffee. Arabica is lighter, with brighter acidity and more complex aroma. Many people like a blend of both. Read more in Arabica vs Robusta.
