For a Vietnamese phin, start with 12-18g coffee for one person. Use the lower end for a small 4oz phin and the higher end for a 6oz phin or iced drink. If you do not have scales, start with 2-3 level tablespoons and adjust by taste.
The direct answer is simple, but the best dose depends on phin size, grind, roast, condensed milk and ice. A phin makes concentrated filter coffee, so small changes show up quickly.
Starting Dose Table
| Phin size | Coffee dose | Water amount | Best for |
|---|---|---|---|
| 4oz | 12-15g | 70-110ml | Small strong drink |
| 6oz | 15-18g | 100-160ml | Everyday phin coffee |
| 8oz | 18-24g | 150-230ml | Larger cup or iced base |
Use these ranges as a starting point. Different coffees absorb water differently, and some phins drain faster than others.
Tablespoons Versus Scales
Scales make phin coffee easier because tablespoons vary with grind size and bean density. A spoonful of fine dark coffee can weigh differently from a spoonful of lighter, coarser coffee.
If you are using spoons, start with 2 level tablespoons for a 4oz phin and 3 level tablespoons for a 6oz phin. Keep the water amount steady for a few brews so you know what changed.
Dose For Condensed Milk
Condensed milk softens bitterness and adds sweetness, but it can also make weak coffee taste flat. For condensed milk coffee, use enough coffee to remain present after stirring. A 15-18g dose in a 6oz phin is a sensible starting point.
For the drink method, read Vietnamese coffee with condensed milk.
Dose For Iced Coffee
Ice dilutes the drink, so iced Vietnamese coffee needs a stronger base. Try 15-20g coffee with 90-130ml water, then pour over ice after stirring with condensed milk. If the final glass tastes watery, reduce water before adding more milk.

Adjusting Strength
| Taste problem | Adjustment |
|---|---|
| Weak and watery | More coffee, less water or slightly finer grind |
| Bitter and dry | Coarser grind, less coffee or slightly cooler water |
| Sour or hollow | Finer grind or longer contact |
| Muddy | Coarser grind and gentler insert placement |

Conclusion
Start with 12-18g coffee for a single phin and write down what you used. The best dose is the one that tastes balanced with your phin, cup and drink style. Change one variable at a time and the method becomes much calmer.
Frequently asked questions
How many grams of coffee should I use in a phin?
Start with 12-18g for a single-cup phin, then adjust by drink size, coffee strength and whether you are adding condensed milk or ice.
Can I use tablespoons instead of scales?
Yes, but scales are more repeatable. As a rough start, use 2-3 level tablespoons depending on phin size and coffee density.
Why is my phin coffee weak?
You may be using too little coffee, too much water, too coarse a grind or a phin that is too large for the dose.
How much coffee for iced Vietnamese coffee?
Use a slightly stronger base, often around 15-20g coffee with 90-130ml water for one iced drink.
