Origins of Thai Iced Tea

Key Ingredients

The primary ingredients used to make Thai Iced Tea include:

Tea Leaves

Thai Iced Tea is traditionally made with strong black tea leaves. The most commonly used tea is Ceylon tea, which originates from Sri Lanka and has a robust flavor profile. Occasionally, Assam tea leaves are used as an alternative due to their similar characteristics.

Spices and Flavorings

To achieve the distinct taste of Thai Iced Tea, various spices and flavorings are added to the tea mixture. Some of the most commonly used ingredients include star anise, cardamom, and tamarind. These spices not only enhance the tea’s flavor but also contribute to its signature aroma.

Food Coloring

The vibrant orange color of Thai Iced Tea is achieved by adding food coloring to the tea mixture. Although not a natural ingredient, the food coloring is purely for aesthetic purposes and does not affect the taste of the tea.


Sweetened condensed milk or sugar is used to add sweetness to Thai Iced Tea. The amount of sweetness can be adjusted according to personal preference.


Evaporated milk or coconut milk is added to Thai Iced Tea to create its signature creamy and rich texture.

Variations of Thai Iced Tea

There are several variations of Thai Iced Tea, each with its unique twist. Some of the most popular variations include:

Thai Iced Green Tea

This variation uses green tea leaves instead of black tea leaves, giving it a milder flavor and a distinct green color. The other ingredients remain the same, resulting in a refreshing and lighter version of the traditional Thai Iced Tea.

Thai Iced Tea with Boba

Boba, or tapioca pearls, are often added to Thai Iced Tea, creating a fun and chewy texture. The combination of the creamy tea and chewy boba creates a unique and enjoyable drinking experience.

Thai Iced Coffee

Known as “Oliang” in Thai, Thai Iced Coffee is made with strong coffee instead of tea leaves. The coffee is mixed with spices, sweeteners, and dairy, resulting in a rich and aromatic beverage that shares similarities with its tea counterpart.

How to Make Thai Iced Tea at Home

Making Thai Iced Tea at home is simple and allows you to adjust the sweetness and creaminess according to your preferences. Here’s a step-by-step guide to making Thai Iced Tea at home:

  1. Prepare the tea and spices: In a large pot, bring 4 cups of water to a boil. Add 1 cup of black tea leaves (preferably Ceylon tea), 2-3 star anise, 3-4 crushed cardamom pods, and 1 teaspoon of tamarind paste. Boil the mixture for 3-5 minutes.
  2. Add food coloring: Add a few drops of orange food coloring to the pot. This step is optional, but it will give your Thai Iced Tea its signature color.
  3. Strain the tea mixture: Remove the pot from the heat and let the tea steep for 5-10 minutes. Strain the tea mixture through a fine-mesh sieve or cheesecloth, discarding the tea leaves and spices.
  4. Sweeten the tea: Stir in ½ cup of sugar or sweetened condensed milk to the strained tea. Adjust the sweetness according to your preference.
  5. Chill the tea: Allow the tea to cool to room temperature, then refrigerate it for at least 1 hour or until chilled.
  6. Assemble the Thai Iced Tea: Fill a glass with ice, pour the chilled tea over the ice, and top with a generous splash of evaporated milk or coconut milk. Stir well before enjoying your homemade Thai Iced Tea.

Vegan and Dairy-Free Options

For those who prefer a vegan or dairy-free version of Thai Iced Tea, you can easily substitute the sweetened condensed milk and evaporated milk with plant-based alternatives. Some popular options include:

  • Coconut milk: This dairy-free alternative adds a rich and creamy texture to Thai Iced Tea, while also providing a subtle coconut flavor.
  • Almond milk: Almond milk is another great vegan option, offering a smooth and creamy texture without overpowering the tea’s flavors.
  • Soy milk: Soy milk is an ideal vegan substitute due to its neutral taste and creamy consistency.

Serving Suggestions

Thai Iced Tea can be served in various ways, depending on your preference and the occasion. Some popular serving suggestions include:

  • Serve with a straw: A straw allows you to sip the tea and enjoy the layers of flavors as they mix together.
  • Serve in a tall glass: A tall glass showcases the vibrant color and layers of Thai Iced Tea, making it visually appealing.
  • Garnish with a slice of lemon or lime: Adding a slice of lemon or lime to your Thai Iced Tea not only adds a pop of color but also provides a refreshing citrus twist.

Pairing Thai Iced Tea with Food

Thai Iced Tea pairs well with a variety of dishes, especially spicy Thai food. The creamy and sweet flavors of the tea help balance and cool down the heat from the spices. Some popular food pairings include:

  • Thai curries: Green, red, or yellow curry dishes pair well with Thai Iced Tea, as the tea’s sweetness and creaminess help to counteract the spiciness of the curry.
  • Pad Thai: The tangy and flavorful Pad Thai noodles complement the sweet and creamy Thai Iced Tea, creating a delightful contrast of flavors.
  • Spicy salads: Thai Iced Tea pairs well with spicy salads, such as Som Tum (green papaya salad) or Larb, as the tea helps to mellow the heat from the chilies.

Health Benefits of Thai Iced Tea

While Thai Iced Tea is a delicious and refreshing beverage, it also offers several health benefits, owing to its key ingredients:

  • Black tea: Rich in antioxidants, black tea can help reduce inflammation, lower blood pressure, and improve heart health.
  • Spices: Star anise, cardamom, and tamarind are known for their anti-inflammatory and digestive properties.
  • Dairy-free options: Using dairy-free alternatives like coconut milk, almond milk, or soy milk can provide additional health benefits, such as healthy fats and essential nutrients.

While you can make Thai Iced Tea at home, there’s nothing quite like enjoying an authentic and freshly prepared Thai Iced Tea from a Thai restaurant or street vendor. Some of the best places to enjoy Thai Iced Tea include:
