What Is Egg Coffee? Hanoi’s Strangest, Best Drink, Explained
Vietnamese egg coffee, or ca phe trung, is a Hanoi specialty made by whisking egg yolk with sugar and condensed milk into a thick, pale foam, then pouring it over hot Vietnamese-style robusta coffee. It was invented in 1946 by Nguyen Van Giang, a bartender at Hanoi’s Metropole Hotel, during a wartime milk shortage, and the shop he opened afterward — Cafe Giang — still serves it in the Old Quarter today. Done right, it tastes far closer to a warm tiramisu than anything eggy.
What Exactly Is Egg Coffee, and What Does It Taste Like?
Egg coffee is built from two layers: hot, strong Vietnamese robusta coffee on the bottom, and a whisked topping of egg yolk, sugar, and condensed milk on top, beaten until it is pale, thick, and airy. The result tastes closer to a warm tiramisu or a liquid custard than anything egg-flavored — done correctly, the yolk is not detectable as “egg” at all, just rich, sweet foam floating on strong, slightly bitter coffee. Some shops gently double-boil the cup in a bowl of hot water afterward so the foam holds its texture while you drink.
Where Did Egg Coffee Come From?
Egg coffee was invented in 1946 by Nguyen Van Giang, who was working at the Sofitel Legend Metropole Hotel in Hanoi during the First Indochina War, when fresh milk was scarce. Giang began whisking egg yolk with sugar as a milk substitute for coffee, and the drink caught on quickly enough that he left the hotel to open his own shop. That shop, Cafe Giang, still operates today in Hanoi’s Old Quarter, now run by Giang’s son, Nguyen Van Do.

TTC Verdict: Egg coffee is not a gimmick invented for tourist cameras — it is a genuine wartime improvisation that has been refined in the same Hanoi shop for nearly 80 years. Order it hot the first time you try it, close to how Nguyen Van Giang served it in 1946, before trying any of the iced or flavored spin-offs now common around the Old Quarter.
No, not when it is made correctly. The egg yolk is whisked with sugar and condensed milk until it is pale, thick, and airy, similar to a zabaglione or the custard layer in tiramisu — the coffee’s bitterness and the sugar mask any eggy flavor.
Cafe Giang and other established Hanoi cafes have served egg coffee daily since 1946 using fresh eggs, and it is considered a safe, everyday local specialty. As with any dish containing lightly cooked egg, travelers who are pregnant, immunocompromised, or have an egg allergy should ask about preparation before ordering.
Cafe Giang in the Old Quarter is the original shop, still run by the founder’s family, and remains the most famous place to try it, though many cafes around Hoan Kiem Lake now serve their own versions.
