Method
- Spoon the condensed milk into the bottom of a tall glass. The amount is personal: 2 tbsp for less sweet, 4 for the full Vientiane street-cart sweetness.
- Place the phin filter on top of a small bowl or cup (not yet over the glass). Add the ground coffee, level it, then place the press disc on top.
- Pour 20ml of boiling water over the grounds. Wait 30 seconds for them to swell — the bloom step.
- Pour the remaining 100ml boiling water in. Place the lid on the phin. The water should drip slowly through the grounds — a properly tightened phin produces about 50–80 drops per minute, finishing in 4–5 minutes.
- Once dripping is complete, lift the phin off and pour the hot coffee directly over the condensed milk. Stir vigorously with a long spoon for 30 seconds; the mixture should turn a uniform creamy caramel colour.
- Add ice to the glass — to the brim. The hot coffee-milk mixture pours over the ice and chills almost instantly. Stir once. Serve with a long spoon and a straw.
Common questions
Can Kafe Lao be made ahead?
Kafe Lao is best made and eaten the same day, but the components can be prepped earlier — chop and measure the ingredients up to a day ahead, refrigerated separately. Final cooking takes about 5 minutes.
Is Kafe Lao spicy?
Kafe Lao as written is mild to mildly warming — the heat comes from aromatics rather than chili. Add fresh sliced chili or chili oil at the end if you'd like to push it spicier.
Is Kafe Lao vegetarian or gluten-free?
This recipe is suitable for most diets. If you have specific restrictions, the substitutions section in each ingredient note covers the most common swaps.
How hard is Kafe Lao to make at home?
Kafe Lao is approachable for a home cook with basic stove skills — total time about 10 minutes, no special technique required.
Can Kafe Lao be scaled up or down?
This recipe is written for 1 servings. To scale, multiply each ingredient proportionally; the cooking times stay the same up to about double the volume. Beyond that, expect to cook in batches because of pan size and heat distribution.
Cultural Note
Lao coffee comes primarily from the Bolaven Plateau in southern Laos — the country's prime coffee-growing region, producing both Robusta (cheaper, used for everyday) and Arabica (the premium beans). The brewing technique is essentially identical to Vietnamese ca phe sua da, with the same phin filter and condensed milk; the Lao version tends to be slightly milder in roast and uses more Arabica blend. Vientiane has thriving cafe culture with both traditional kafe Lao and modern espresso bars; the morning kafe-and-baguette is the classic Lao breakfast.
