Let’s dive into the wonderfully spiced world of Thai iced tea.


🧂 Traditional Spices in Thai Iced Tea

While recipes can vary, traditional Thai iced tea includes a combination of the following key spices:

🌱 1. Star Anise

  • Flavor Profile: Sweet, licorice-like, and mildly peppery.

  • Role: One of the most prominent spices in Thai tea. It provides a distinct, aromatic sweetness that is both soothing and slightly exotic.

🌿 2. Cardamom

  • Flavor Profile: Complex, citrusy, slightly minty, and spicy.

  • Role: Cardamom adds a subtle floral and citrusy nuance that balances the deeper notes of the tea and sugar.

🌼 3. Cloves

  • Flavor Profile: Warm, sweet, and pungent with a slight bitterness.

  • Role: Adds warmth and depth to the tea. Its bold presence enhances the richness of the tea when paired with sweet milk.

🪵 4. Cinnamon

  • Flavor Profile: Warm, sweet, and woody.

  • Role: Rounds out the spice mix with comforting warmth. Not always present, but often used in more robust versions of Thai tea.


🍵 Black Tea: The Foundation

While not a spice, it’s important to recognize that strong black tea is the canvas for all the other flavors.

  • Tea Types Commonly Used: Ceylon tea (originally), Assam, or a Thai-specific black tea blend (often artificially colored).

  • Flavor Profile: Bold, tannic, and slightly astringent, which balances the sweetness of the condensed milk and sugar.


🌈 Coloring Agents: Natural and Artificial

Although not a spice, many Thai tea blends include food coloring to achieve that iconic bright orange color.

  • Artificial: FD&C Yellow No. 6 (often used in commercial Thai tea blends like “Number One Brand” or “Pantai”).

  • Natural Alternatives: Turmeric or annatto seeds can be used if you want to avoid artificial dyes.


🧋 The Role of Sweeteners and Dairy

🥫 Sweetened Condensed Milk

  • Adds sweetness and creamy texture.

  • Traditional Thai iced tea is rarely served without it.

🍼 Evaporated Milk or Half-and-Half

  • Poured over the tea for the signature layered look and rich mouthfeel.


📜 Traditional vs. Commercial Thai Tea Spice Mixes

Homemade (Traditional) Spices Mix

In many Thai households or small teashops, Thai iced tea is brewed using a custom spice blend. Here’s what it might include:

  • Crushed star anise

  • Green or black cardamom pods

  • Whole cloves

  • A cinnamon stick

  • Optional: ground tamarind seed or vanilla bean for added flavor

These ingredients are steeped with black tea to create a deeply aromatic infusion.

Commercial Thai Tea Mix

Most popular Thai iced teas (especially outside of Thailand) come from pre-packaged tea mixes like:

  • Cha Tra Mue (Number One Brand)

  • Pantai Norasingh Thai Tea Mix

These mixes contain black tea, artificial coloring, and added flavorings. The spice profile is there but less distinguishable due to mass production.
