How to Make Vietnamese Iced Coffee (Cà Phê Sữa Đá) at Home

TL;DR

How to make Vietnamese iced coffee: brew 25g coffee in a phin, bloom 20ml then pour 50ml, add 2 spoons of condensed milk, stir and serve over ice.

What is ca phe sua da

Ca phe sua da is the national drink of Vietnam: dark-roasted coffee brewed drip by drip in a small phin filter, mixed with sweetened condensed milk and poured over a full glass of ice. The deep bitterness of the coffee blends with the creamy sweetness of the milk to create a uniquely balanced flavor that is refreshing and energizing for the morning.

The heart of an authentic glass lies in the aluminum phin filter and the tamping technique. The phin lets the coffee flow slowly, extracting gradually so the brew is thicker, richer and more aromatic than fast machine espresso. This is also the detail many international readers are curious about when discovering Vietnamese coffee.

This guide walks you through every step with specific measurements so you can brew a glass of ca phe sua da as good as the cafe right at home, along with a few fun variations.

Ingredients you will need

For one standard glass you need: 25g of medium-ground dark-roast coffee, about 70ml of hot water at 92 to 96 degrees C, 2 teaspoons of sweetened condensed milk, and a glass full of ice cubes.

Tools include a medium aluminum phin filter, a heat-resistant glass and a long spoon for stirring. Use clean filtered water so the coffee aroma stays pure.

As for the beans, Robusta or a Robusta and Arabica blend at a 7 to 3 ratio gives a bold bitter taste, a sweet finish and a beautiful brown crema, perfectly suited to traditional ca phe sua da.

How to make ca phe sua da step by step

Step 1: Add 2 teaspoons of sweetened condensed milk to the bottom of the glass. Rinse the phin with a little hot water to warm it, then add 25g of ground coffee and shake gently to level the surface.

Step 2: Place the gravity press on top and press lightly to tamp the grounds moderately. Pour about 20ml of hot water to bloom and wait 30 to 45 seconds for the grounds to swell evenly, releasing a wonderful aroma.

Secrets to a perfect brew

The most important secret is tamping the phin just right: too tight and the water will not flow or drips very slowly, scorching the coffee and making it harshly bitter; too loose and the water rushes through, leaving the coffee weak and watery. Press until you feel slight resistance, then stop.

Blooming with 20ml of water before the full pour is a trick that helps the grounds swell evenly and open up all the aroma before extraction, giving a far more fragrant and intense brew. Do not skip this step.

Water temperature should be around 92 to 96 degrees C, meaning boiled water left to cool for about a minute. Water that is too hot makes the coffee bitter and astringent, while water too cool will not extract enough. Finally, use large ice cubes and a very cold glass so the ice melts slowly and the coffee does not dilute too fast.

Variations and serving at events

From the base recipe you can create many appealing non-alcoholic versions: coconut coffee with rich creamy coconut milk, bac xiu with more milk and less coffee for those who like it mild, or salted coffee with a savory salted cream layer that is hugely popular right now.

At events, weddings or conferences, a phin-brewed ca phe sua da station made on the spot is always a highlight guests love. The sight of the dripping phin and the cold iced glass feels both familiar and distinctly Vietnamese, making it an elegant non-alcoholic signature choice for all ages.

Frequently asked questions (FAQ)

Which coffee is best for ca phe sua da?

Dark-roast Robusta beans or a Robusta and Arabica blend at a 7 to 3 ratio give a bold bitter taste, a sweet finish and a lovely brown crema, perfectly suited to the traditional style.

How much condensed milk is just right?

About 2 teaspoons of sweetened condensed milk per glass is balanced; add a little more for a creamier sweet taste, or reduce to one and a half teaspoons for a stronger coffee flavor.

Why does the coffee drip too slowly or too fast?

Too slow is usually from tamping the phin too tight or grinding too fine; too fast comes from tamping too loose or grinding too coarse. Adjust the tamping pressure and grind size to fix it.

Do I need to bloom the coffee before the full pour?

Yes, pouring about 20ml of bloom water for 30 to 45 seconds helps the grounds swell evenly and open up all the aroma, giving a noticeably richer and more fragrant brew.

Can I book a ca phe sua da station for an event?

Yes, the mobile bar service at bartender.com.vn sets up on-site phin-brewed ca phe sua da stations with a non-alcoholic drink menu tailored to your event.
