How to Make Vietnamese Coffee Using a Phin Filter

If you’ve ever seen a small metal coffee dripper slowly percolating atop a glass cup, you’ve probably witnessed a Vietnamese coffee being made. But how exactly does it work? This classic brewing method—rooted in Vietnam’s strong coffee culture—is simple, hands-off, and produces a bold, sweet shot of coffee that’s hard to replicate with other brewers.

To make Vietnamese coffee the traditional way, you’ll need a phin filter, hot water around 95°C, 10–12g of coffee grounds, and either a creamer ball or a bit of sweetened condensed milk. The entire brew takes about 3 minutes, resulting in a rich, concentrated cup ready to enjoy straight or with your preferred sweetener.

What Is a Vietnamese Coffee Phin?

The Vietnamese coffee phin (or phin filter) is a small, single-serving metal drip brewer consisting of a base, a brewing chamber, and a perforated lid. Unlike espresso machines or pour-over cones, the phin relies purely on gravity and time to extract coffee. Its compact design makes it ideal for brewing one strong cup at a time, directly into your drinking vessel—usually a heatproof glass.

Why Add Sweetened Condensed Milk or Creamer?

Traditional Vietnamese coffee is almost always served with sweetened condensed milk—or a creamer ball for a lighter option. The reason is simple: the coffee is brewed strong, often using dark-roasted beans, and the sweetness balances the intensity. In Vietnam, condensed milk became popular both for its flavor and because refrigeration was historically limited. Today, it defines the signature taste of a classic Vietnamese coffee.

How to Brew Coffee with a Vietnamese Phin Filter: Step-by-Step

Follow these steps to brew a classic Vietnamese coffee using a phin:

• Step 1. Add a creamer ball or a small amount of sweetened condensed milk to the bottom of your cup. This sweetens and tempers the strong brew.
• Step 2. Remove the small press-down lid (also called the filter top or spreader) from the phin.
• Step 3. Add approximately two level scoops of coffee grounds—about 10–12g—into the brewing chamber of the phin.
• Step 4. Reinsert and tighten the small lid onto the coffee grounds. This helps ensure even extraction by applying slight pressure.
• Step 5. Pour roughly 95°C hot water evenly over the coffee grounds. Start with a small amount to let the coffee bloom, then fill the chamber.
• Step 6. Let the coffee drip slowly—this should take about 3 minutes. The slow extraction is part of what gives Vietnamese coffee its strength and body.
• Step 7. Once all the water has passed through, remove the phin and stir your coffee. Your brew is now ready to enjoy.

Common Mistakes to Avoid

When brewing with a phin, avoid these pitfalls:

• Using water that’s too cool (below 90°C) or too hot (above 100°C), which can under-extract or scorch the coffee.
• Not tightening the filter lid properly, leading to uneven flow or fast dripping.
• Overfilling the coffee chamber, which can clog the filter and stall the brew.
• Rushing the brew time—waiting less than 3 minutes often results in underdeveloped flavor.

Frequently Asked Questions

What kind of coffee should I use in a Vietnamese phin?

Traditionally, Vietnamese coffee is made with a dark roasted robusta or a dark robusta-arabica blend. These beans produce a bold, bitter profile that pairs well with sweetened condensed milk. You can also experiment with medium or dark roasted single origins if you prefer a more nuanced cup.

Do I need to use sweetened condensed milk?

No, sweetened condensed milk is traditional but optional. You can use a creamer ball, regular milk, sugar, or drink it black depending on your taste. The original style, however, uses condensed milk for balance against the strong, dark brew.

How much coffee should I put in a phin?

Use about two level scoops of ground coffee, roughly 10–12g, for a standard single serving. Adjust based on your phin size and taste preference, but this is the typical range used in traditional preparation.

Why is my phin dripping too fast or too slow?

A drip rate that’s too fast usually means the coffee grind is too coarse, the filter pressure is too low, or the coffee bed isn’t tamped evenly. If it’s too slow, the grind may be too fine, or the filter may be clogged. Aim for a slow, steady drip over about 3 minutes.

Can I make iced Vietnamese coffee with a phin?

Yes. Brew the coffee hot using the phin as directed, then pour it over ice. For traditional iced Vietnamese coffee, add condensed milk first over ice, then pour the hot brew on top so it melts slightly into the milk.
