Good news first: any coffee works in a phin. You don't need a special brand or a special bag. But a few choices — the bean, the roast and above all the grind — make the difference between a thin, sour cup and the bold, chocolatey coffee you remember from a Vietnamese café. Here's how to choose.
Robusta, Arabica, or a blend?
- Robusta is the traditional backbone of Vietnamese coffee. It has a heavier body, more bitterness and more caffeine than Arabica, which is exactly why it stands up to sweetened condensed milk and ice. Look for “100% Robusta” or “Vietnamese-style” on the bag.
- Arabica is brighter and smoother. A medium-dark or dark roast makes a gentler phin cup that's lovely black over ice.
- A Robusta–Arabica blend is what many cafés use: body from the Robusta, a little brightness from the Arabica. A good place to start if you drink it with milk.
Which roast?
Classic Vietnamese coffee is dark: bold and chocolatey, built for milk and ice. If you usually drink light-roast pour-over, a medium-dark roast is a friendlier first step. Very dark, oily roasts can taste ashy — if yours does, let the boiling water rest 30–60 seconds before you pour.
The grind matters more than the bean
A phin has no paper filter and no pump, so grind size controls how fast the water passes through. Aim for medium-coarse: a bit coarser than table salt, somewhere between drip and French press.
- Espresso-fine: clogs the phin; the drip stalls.
- Drip / medium: works, but often slow.
- Medium-coarse: the sweet spot — about 4–6 minutes of steady drops.
- Coarse / French press: runs too fast and tastes thin.
If you grind at home, start one or two clicks coarser than your drip setting and adjust from there. If your cup comes out weak and fast, go finer — see why your phin drips too fast.
Pre-ground is fine
Many Vietnamese-style coffees are sold already ground for the phin, and they're a great place to start. Regular “drip” grind works too; just expect a slower drip.
How much coffee?
Start with 2 tablespoons per phin. Go up to 3 for a stronger, milk-ready brew — especially for Vietnamese iced coffee, where the ice dilutes it fast.
Keep it fresh
Store coffee in an airtight container away from light and heat, and use it within a few weeks of opening. Stale coffee tastes flat no matter how well you brew it.
Our advice: try two or three
We don't sell coffee, and we don't have a favorite brand to push. Buy two or three bags, brew each the same way, and write down which one you liked. That little log is worth more than any buying guide.
