Strong-brewed black tea with star anise and cardamom, sweetened with condensed milk and topped with evaporated milk over ice — bright orange from food coloring in the Thai tea blend.
Cha yen developed in mid-20th-century Bangkok street stalls and shophouse restaurants, where pre-blended cha thai powder sold by brands like ChaTraMue (founded 1945) made the drink reproducible. The black tea base came from Northern Thai plantations established during the early 1900s; the orange dye and added spices were part of the commercial blend, not a folk recipe. The drink is now ubiquitous at street stalls, food courts, and night markets, almost always poured over crushed ice in a tall plastic bag with a rubber band.
Bangkok shophouse drink standardised by ChaTraMue (founded 1945), whose pre-blended powder gave street stalls a reproducible orange-coral colour. The black tea base comes from Northern Thai plantations of the early 1900s; the dye and spices are part of the blend, not folk recipe.
The colour hits first — a Day-Glo orange-coral that doesn't exist in any other tea on earth. The first sip up the straw is cold, very sweet, and tannic enough to scrape your tongue clean; star anise and cardamom drift in behind. The evaporated milk on top is creamier and less sweet than the tea below — stir it through and the whole thing turns pale apricot. Without the food colour it would still taste the same, but the colour is the dish. Too watery and the spices vanish; too long-steeped and it goes bitter and chalky.
Two engineering details. First, the tannin level: cha thai is brewed roughly four times as strong as Western iced tea because dilution from ice and dairy is enormous — under-brew and you get pink milk water. Second, the layered float: evaporated milk has lower sugar than the sweetened tea, so it's denser and sinks; add it to a still glass and you get the streaky two-tone look that defines the drink at Thai stalls.
Variations
ChaTraMue (the 1945 brand reference); Number One brand (the budget shop alternative); cha yen yen-yen (extra ice, weaker); cha dam yen (no milk, sweet black-tea-only); cha manao (lime instead of milk); modern third-wave specialty cafés brew Assam OP grade without dye.

4 steps · 10 min active + 5 min waiting
- 15 min
Bring 1L water to a rolling boil. Add 60g Thai tea mix (cha thai — black tea blended with star anise, crushed cardamom pods, and orange food coloring) into a cha thai sock filter or large tea bag.
- 28 min
Steep the sock in the boiling water for 5 minutes. Lift, drain, lower back in for another 3 minutes — the brew should be opaque dark mahogany. Pull out and discard leaves.
Watch outSteep until the brew is opaque dark-mahogany — brew it four times stronger than Western iced tea, or the ice and milk dilute it to pink milk-water.
- 32 min
Stir in 6 tablespoons sweetened condensed milk and 4 tablespoons sugar while still hot. Taste — it should be aggressively sweet at this stage; ice and milk will dilute it.
Watch outSweeten it while hot until it tastes almost too sweet — the ice and evaporated milk to come will pull it right back.
- 45 min
Cool to room temperature. Fill 4 tall glasses with crushed ice; pour the tea to three-quarters. Float 3 tablespoons cold evaporated milk on top of each — it sinks in pale-orange streaks. Serve with a long spoon and straw.
Watch outPour the cold evaporated milk gently onto still tea — it's denser than the sweet tea, so it sinks in pale-orange streaks for the two-tone look.
