Vietnamese Iced Milk Coffee — the Nation's Favourite Drink

If you could pick only one drink to introduce Vietnam, many people would choose iced milk coffee — cà phê sữa đá. A glass full of ice, dark coffee swirled with condensed milk into a milky brown, strong, rich and sweet. It is everywhere, from sidewalk stalls to offices.

Why condensed milk?

One commonly told explanation: in the late 19th century, when coffee arrived in Vietnam with the French, fresh milk was hard to keep in the hot, humid climate. Canned sweetened condensed milk lasted much longer, so it became the natural choice. Its sweet richness also balances the bold, bitter taste of Robusta — the coffee grown most widely in Vietnam.

Whatever its origin, the combination of phin, condensed milk and ice has become part of everyday life, paired with the slow rhythm of sidewalk cafés and the mornings before work.

What you need

• A phin filter (aluminium or stainless steel, single-cup size).
• About 20–25 g of ground coffee, medium grind — finer than for pour-over, but not as fine as espresso.
• About 20–30 ml of sweetened condensed milk (2–3 tablespoons), to taste.
• Hot water at about 90–96 °C. Water that has just boiled and rested for about 30 seconds is right.
• A glass full of ice.

Step by step

1. Rinse the phin and cup with hot water to keep them warm.
2. Add the condensed milk to the bottom of the cup.
3. Add the coffee to the phin, shake gently to level it, place the press insert on top and press lightly.
4. Let it bloom. Pour in about 20 ml of hot water and wait 20–30 seconds for the grounds to swell.
5. Top up with water almost to the rim and put on the lid. The coffee drips through in about 4–5 minutes. If it runs too fast, grind finer or press harder next time; if too slow, do the opposite.
6. Stir the coffee into the condensed milk until fully blended.
7. Pour over ice, stir a few more times to chill evenly, and enjoy.

Because the ice melts and dilutes the drink, brew iced coffee a little stronger than you would for a hot cup.

A quick version with instant coffee

There isn't always time to wait for a phin. Instant coffee is the shortcut: dissolve it in a small amount of hot water following the pack instructions, stir in the condensed milk and pour over ice. It tastes a little different from phin coffee, but keeps the "strong, rich, sweet" spirit of the drink.

One drink, many stories

In Vietnam, a glass of iced milk coffee is rarely just a drink. It is a reason to sit down with friends, the first cup of a working day, a place to meet and do business. The articles in the "Vietnamese coffee culture" series continue with sidewalk café culture and the café as a "second office".
