What to check first

Brewer type and filter type

You’ll need a Vietnamese coffee filter, often called a phin. These are typically metal, with a perforated plate and a press. Make sure yours is clean and all parts are present. It’s a simple tool, but crucial for the right result.

Water quality and temperature

Use good, filtered water. Tap water can sometimes add off-flavors. Heat it to just off the boil, around 195-205°F. Too hot and you can scorch the grounds; too cool and you won’t extract enough flavor.

Grind size and coffee freshness

This is a big one for how to make the best Vietnamese coffee. You want a fine grind, almost like espresso, but maybe a touch coarser. Freshly ground beans make a world of difference. Stale coffee just won’t deliver that punch.

Coffee-to-water ratio

A good starting point is about 1-2 tablespoons of coffee grounds per 4-6 oz of water. It sounds like a lot of coffee, but remember this is a concentrated brew. You can adjust this to your taste later.

Cleanliness/descale status

Make sure your phin is sparkling clean. Any old coffee oils can make your new brew taste bitter. If you use a kettle to heat water, ensure it’s also descaled. A clean setup means a clean cup.

Step-by-step (brew workflow)

1. Prepare the phin. Place the filter plate on top of your mug.

• What “good” looks like: The plate sits securely on the mug rim.
• Common mistake: Using a plate that doesn’t fit your mug, leading to leaks. Avoid this by checking compatibility beforehand.

2. Add coffee grounds. Spoon your finely ground coffee into the phin.

• What “good” looks like: The grounds fill about ¼ to ½ of the chamber.
• Common mistake: Overfilling the phin, which can cause the water to overflow or clog the filter. Don’t pack it down too much.

3. Insert the press. Place the screw-down or gravity press on top of the grounds.

• What “good” looks like: The press is snug against the grounds, not too tight, not too loose.
• Common mistake: Screwing it down too hard, crushing the grounds and blocking the flow. Just apply gentle, even pressure.

4. Add a little hot water. Pour just enough hot water (about 1-2 oz) to wet the grounds.

• What “good” looks like: All the grounds are saturated, and you see a slight bloom.
• Common mistake: Pouring too much water at once, which can lead to uneven extraction. Let it bloom for about 30 seconds.

5. Wait for the bloom. Let the coffee grounds expand and release gases.

• What “good” looks like: The grounds puff up and you might see a few bubbles.
• Common mistake: Skipping this step. The bloom allows for better flavor development. Patience is key here.

6. Fill the phin. Gently pour the remaining hot water into the phin, filling it up.

• What “good” looks like: The water level reaches the top of the phin chamber.
• Common mistake: Pouring too fast or unevenly. This can disturb the grounds and create channels for water to pass through too quickly.

7. Let it drip. Place the lid on and wait for the coffee to slowly drip into your mug.

• What “good” looks like: A slow, steady stream of dark coffee. It should take about 4-5 minutes.
• Common mistake: The drip is too fast or too slow. If it’s too fast, your grind might be too coarse. Too slow means it’s likely too fine or packed too tightly.

8. Add condensed milk. Once the dripping stops, stir in sweetened condensed milk.

• What “good” looks like: A rich, creamy, sweet coffee. Start with a tablespoon or two and adjust.
• Common mistake: Not adding enough condensed milk. Vietnamese coffee is meant to be sweet and decadent.

9. Stir well. Make sure the condensed milk is fully incorporated.

• What “good” looks like: No streaks of condensed milk at the bottom, just a uniform color.
• Common mistake: Not stirring enough, leaving a thick layer at the bottom that you miss.

10. Serve. Pour over ice for an iced coffee (cà phê sữa đá) or enjoy hot.

• What “good” looks like: A refreshing or comforting coffee beverage.
• Common mistake: Drinking it too hot if you prefer it iced. Let it cool slightly before pouring over ice.

Common mistakes (and what happens if you ignore them)

Decision rules (simple if/then)

• If your coffee tastes weak, then add more coffee grounds for the next brew because you are likely under-extracting.
• If your coffee tastes bitter and the drip was very slow, then your grind is likely too fine because it’s choking the filter.
• If your coffee tastes sour and the drip was very fast, then your grind is likely too coarse because the water is rushing through.
• If you see grounds in your cup, then your filter plate has a hole or the press isn’t seated correctly because something is allowing solids to pass.
• If the water doesn’t drip at all, then your grind is too fine or the press is too tight because the flow is completely blocked.
• If your coffee is too sweet, then use less condensed milk next time because you can always add more.
• If your coffee isn’t sweet enough, then add more condensed milk because that’s the signature of Vietnamese coffee.
• If you want a stronger coffee flavor without more caffeine, then try a darker roast because darker roasts are generally more intense.
• If you’re making iced coffee and it tastes diluted, then brew it a little stronger or use less ice because the melting ice will water it down.
• If you’re short on time, then consider a different brewing method because the phin is about the ritual.
• If you’re having trouble finding condensed milk, then check the international aisle of your grocery store or an Asian market because that’s where it’s usually stocked.

FAQ

What kind of coffee beans are best for Vietnamese coffee?

Dark roast beans are traditional and provide the bold, rich flavor. Robusta beans are often used for their strong kick, but a dark roast Arabica blend can also work well.

Can I use a different type of filter?

While you can use other methods, the phin filter is what gives Vietnamese coffee its unique character and slow drip. For the authentic experience, stick with the phin.

How much condensed milk should I use?

This is entirely up to your personal taste! A good starting point is 1-2 tablespoons per serving. Taste and add more if you like it sweeter.

What’s the difference between cà phê sữa nóng and cà phê sữa đá?

“Nóng” means hot, so cà phê sữa nóng is hot Vietnamese coffee with condensed milk. “Đá” means ice, so cà phê sữa đá is the popular iced version.

My coffee is dripping too fast. What did I do wrong?

Your grind might be too coarse, or you didn’t pack the grounds down enough with the press. Try a finer grind or ensure the press is snug.

My coffee isn’t dripping at all. What’s the problem?

This usually means your grind is too fine, or you’ve packed the coffee too tightly. Loosen the press slightly or use a slightly coarser grind.

Can I make Vietnamese coffee without condensed milk?

You can, but it won’t be traditional Vietnamese coffee. It will just be a strong, slow-dripped coffee. Many people enjoy it black, but the condensed milk is a defining element.

How do I clean my phin filter?

After brewing, discard the grounds. Rinse all parts of the phin with hot water. You can use a mild soap occasionally, but rinse thoroughly to remove any residue.
