Learn how to use a Vietnamese coffee maker (phin): its parts, seven brewing steps, water temperature, drip-speed fixes and cleaning for a strong, balanced cup.
A Vietnamese coffee maker has no motor, no heating element and no paper filter; the whole brew depends on gravity and on how firmly the grounds are packed. That makes technique, more than gear, the thing to learn.

A phin is a small metal drip filter that rests on top of a mug. Knowing its pieces makes the brewing steps easier to follow.
Some phins use a gravity insert that simply rests on the grounds, while others use a screw-down insert that can be tightened like a press. Gravity versus screw-down inserts and filter sizes are compared under which vietnamese coffee maker to buy.
Use hot water just off the boil, in the range of about 195-205°F (90-96°C); water that is too hot is one cause of bitter coffee.
Most problems trace back to how the grounds are packed and how hot the water is. Adjust one thing at a time, since changing grind, amount and packing together hides which one fixed the cup. Expect some trial and error before a particular phin and coffee settle into a rhythm. The fixes below assume the grind the coffee's maker suggests for a phin.
| Symptom | Likely cause | Fix |
|---|---|---|
| Drips slowly or not at all | Over-packed or too fine | Loosen the plate, use a coarser grind |
| Drips fast, weak cup | Grind too coarse, plate too light | Grind finer, pack a little firmer |
| Bitter cup | Water too hot, over-extraction | Use water just off the boil |
Take the phin apart, rinse every piece with warm water and dry the parts thoroughly before storing them. Several stainless steel models are listed by their makers as dishwasher safe, but for any other phin, follow the maker's care instructions.
The same brew works hot or over ice, and the iced vietnamese coffee steps cover the milk ratio and the ice.
Yes, though results vary. Traditional phin coffee is a dark roast with a high robusta content, so a different coffee may taste less intense or simply different. Trying a few coffees is the quickest way to find the one you like.
A phin is closer to a drip coffee maker, because gravity pulls the water through the grounds. A French press steeps the grounds in the water, which puts it in a different category of coffee maker.
