How to Prepare Your CoffeeKorean Mix Coffee
Mix coffee is South Korea's everyday cup: instant coffee, sugar and powdered creamer stirred into hot water in one motion, no machine anywhere in sight. It descends from the dabang, the coffee houses that spread from Myeongdong to Jongno through the 1920s, where the coffee was instant and every regular told the server their own proportions — the golden ratio is still argued over and no two accounts agree. Dongsuh Foods fixed it commercially in 1976 with the first three-in-one packet, then moved to the stick in 1987 so drinkers could tip in only part of the sugar. What survives is less a brew than a reflex: office pantries, convenience stores, vending machines, and a spoon that never goes near a grinder.
Ratio breakdown
Ingredients run from the top of the cup to the bottom; the last item is the bottom layer. Values are normalized to a true 100% stack.

Steps
Put the coffee, creamer and sugar into the cup dry
All three are powders, and they dissolve as one if the water hits them together. Pour the water first and the creamer lands on a hot surface and clumps, leaving fat-speckled lumps that no amount of stirring fully breaks up.
Pour in 120 ml of water just off the boil
Creamer is built on vegetable fat and starch, not milk protein — a rolling boil scorches it and the cup turns flat and faintly burnt. Water a few degrees below boiling dissolves everything while keeping the body round.
Stir until nothing rides the surface
The creamer has to emulsify rather than merely wet, so it needs real agitation. Undissolved grains are what make a cup taste thin at the top and cloyingly sweet at the bottom.
Adjust the proportions once, then keep them
The dabang convention was personal calibration — the server mixed to each regular's remembered proportions. There is no single correct cup here, only the one you have settled on, which is why the ratio is still a national argument.
Tips
- Tear a mix stick only part way and tip in some of the sugar — that control is exactly what the 1987 stick format was designed for.
- Warm the cup before you start — 120 ml loses heat fast in ceramic, and the creamer stays properly in suspension only while the cup is hot.
- Stir from the bottom, not the top — the sugar sinks first, so a surface swirl leaves the last mouthful twice as sweet as the first.
Common mistakes
- Boiling water straight onto the powder — it scalds the creamer's vegetable fat, and the finished cup tastes flat with a faint burnt edge.
- Treating one ratio as the authentic one — Korean sources circulate several incompatible golden ratios, so copying a single figure guarantees a cup somebody would send back.
- Swapping in fresh milk — creamer is a non-dairy fat-and-starch powder, and milk thins the body while losing the specific round sweetness that defines the drink.
FAQ
What is the real dabang golden ratio?
There isn't one, and that is the honest answer. Accounts of dabang service agree that each customer told the server their own coffee-to-creamer-to-sugar proportions, and Korean sources circulate several incompatible golden ratios — 2:2:2, 1:2:2, 1:2:1.5 and 1:1:1 all have defenders, while a Korea Times piece quotes 2 coffee : 2 creamer : 3 sugar from a television drama. The proportions here sit mid-range at 1 coffee : 2 creamer : 1½ sugar; the credible range brackets the rest.
Is coffee mix the same as instant coffee?
No. Instant coffee elsewhere is dried coffee alone, to which you add whatever you want. Korean coffee mix is a three-in-one: coffee, sugar and non-dairy creamer pre-measured into one packet, designed to be a finished cup in a single tear-and-pour. Dongsuh Foods introduced it in 1976 and has held the overwhelming majority of the domestic market ever since.
Why creamer rather than milk?
Creamer — prim, in Korean usage — is a shelf-stable powder of vegetable oil, starch syrup and a little milk protein. It needs no refrigeration, which is precisely why it took hold in dabang counters, offices and vending machines, and it gives a rounder, slightly heavier body than fresh milk does at this strength.
