Thai Tea vs Chai: What's the Difference?

★★★★★Explainer·Updated June 2026

Both are spiced black milk teas, so they get mixed up constantly. But they come from different countries, use different spices, and taste nothing alike. Here's how Thai tea and chai really compare.

The short answer

Thai tea (cha yen) is a Thai drink: heavily roasted black tea spiced with star anise and tamarind, dyed bright orange, sweetened with condensed milk, and served over ice. Chai (masala chai) is an Indian drink: black tea simmered with cardamom, ginger, cinnamon, and cloves, mixed with milk and sugar, and usually served hot. Same family, very different flavor.

The spices set them apart

This is the real difference. Thai tea leans on star anise and tamarind for its licorice-sweet, faintly tart backbone. Chai leans on warming baking spices - cardamom first, then ginger, cinnamon, and clove. One tastes like sweet creamy spice over ice; the other tastes like a warm, peppery hug.

FAQ

Is Thai tea the same as chai?

No. Both are spiced black milk teas, but Thai tea (cha yen) uses roasted black tea with star anise and tamarind, is bright orange, and is usually served iced with sweetened condensed milk. Chai (masala chai) uses cardamom, ginger, cinnamon and cloves, is brown, and is usually served hot.

Which has more caffeine, Thai tea or chai?

They're similar - both are built on strong black tea, roughly 40-65 mg per serving. The exact amount depends on how strong it's brewed and whether a chai is made from a concentrate or tea bags.

Is Thai tea or chai sweeter?

Thai tea is usually sweeter because of the sweetened condensed milk. Chai's sweetness varies by how much sugar is added, but it's typically less sweet than a classic cha yen.
