Thai Iced Tea
ชาเย็น
Thai Iced Tea (Cha Yen) is a sweet, vibrant orange drink made from strongly brewed black tea mixed with condensed milk and evaporated milk, poured over crushed ice. It's refreshing, rich, and the perfect antidote to spicy food.
Cultural Origin
Cha yen, Thai iced tea, evolved in mid-20th-century Bangkok as Ceylon black tea — imported through British-era trade — was sweetened with sugar and finished with evaporated and condensed milk for the local sweet-tooth palate. The orange colour comes from food colouring added to a proprietary spice-blend tea sold by brands such as ChaTraMue. It is now a default street-cart beverage nationwide and a fixture of Thai restaurants abroad.

The tea itself is strong and slightly astringent, brewed with spices such as star anise, which keeps the drink from tasting purely of sugar despite the heavy sweetening.
How Thai Iced Tea Is Made
- 1
Brewing
Thai tea mix is steeped in hot water for several minutes until dark orange and strongly flavoured.
- 2
Sweetening
Sugar is stirred into the hot tea while it is still warm, so it dissolves fully rather than settling at the bottom of the glass.
- 3
Cooling
The sweetened tea is poured over a full glass of crushed ice, which drops the temperature rapidly.
- 4
Layering
Evaporated milk is poured over the back of a spoon so it sits on top rather than mixing straight through, creating the two-tone look.
- 5
Finishing
Condensed milk is sometimes added as well, and the drink is served with a straw for the drinker to stir themselves.
When It’s Eaten
Drunk throughout the day rather than tied to a particular meal, and especially reached for alongside spicy food, where the sweetness and cold temperature cut the heat.
How to Order It
- ขอชาเย็นหนึ่งแก้ว
- kor cha yen neung gaew

What people get wrong
Assuming it is simply iced black tea with milk. The colour and flavour depend on the specific spiced tea blend, so a version made with ordinary tea bags tastes noticeably different.
Where to Try It
Every street stall, restaurant, and 7-Eleven in Thailand — it's one of the most ubiquitous drinks in the country.
Tips
- Stir slowly before drinking to create a gradient swirl — visually dramatic and it mixes the sweetness gradually.
- Ask for less condensed milk ('wan noi') if you prefer it less sweet.
