Dalgona Coffee originated in South Korea during the COVID‑19 pandemic as a viral social‑media trend, offering a simple way to make a café‑style drink at home using instant coffee and a handheld frother.

While the classic version uses instant coffee, brown sugar, and hot water, some Korean cafés serve it with added cocoa powder, matcha, or flavored syrups to create seasonal twists.

It is typically served over a glass of cold milk and ice, with the thick coffee foam spooned on top, allowing the drinker to stir the layers together before sipping.

Dalgona Coffee became a popular at‑home treat during lockdowns, but it is now enjoyed year‑round as a refreshing summer beverage or a quick pick‑me‑up during work breaks.

Its appeal lies in the dramatic visual contrast between the dark, airy foam and the bright milk, as well as the simple, no‑brew technique that anyone can replicate with minimal equipment.

Authentic ingredients are instant coffee, brown sugar, and hot water for the foam, plus cold milk and ice. Substitutes include espresso powder for coffee, white or coconut sugar for brown sugar, and plant‑based milks for dairy.

Dalgona Coffee pairs nicely with Korean pastries such as hotteok or sweet red bean buns, and it can be enjoyed alongside a light fruit tea or a chilled barley drink (bori‑susu).

Common errors include using lukewarm water (which prevents proper foam formation), under‑frothing the mixture, and adding too much water, which results in a runny texture.

A handheld frother incorporates air much faster and creates a stable, glossy foam in about two minutes, whereas a whisk requires significantly more effort and time to achieve the same consistency.

The foam can be stored in an airtight container in the refrigerator for up to 24 hours; re‑whisk briefly before topping the milk. The milk‑and‑ice base should be assembled just before serving.
