The Formula Behind Thai Iced Tea: Ingredients, Preparation, and Variations

Thai Iced Tea, known locally as “Cha Yen,” is a popular beverage from Thailand that has gained international recognition for its distinct flavor, striking orange color, and creamy texture. It is widely consumed as a refreshing drink, especially in hot climates. This article explores the formula behind Thai Iced Tea, including its ingredients, preparation process, and common variations.

1. Origins and Characteristics

Thai Iced Tea originated from Thailand and was traditionally made with strong black tea brewed with spices and served over ice with condensed or evaporated milk. Its signature orange hue is often attributed to food coloring, though some versions may obtain color from the tea leaves and spices used.

The beverage is known for its balance of bold tea flavor, sweetness, and creaminess. It is commonly served in Thai restaurants worldwide and has become a staple in Southeast Asian cuisine.

2. Core Ingredients

A standard Thai Iced Tea recipe includes the following components:

• Thai Tea Mix
  This is a pre-blended mixture usually containing strong black tea (often Ceylon or Assam), food coloring (typically FD&C Yellow #6 or similar), and sometimes spices such as star anise, tamarind, or cardamom. The blend gives Thai Iced Tea its recognizable flavor and orange color.

• Water
  Used to brew the tea. The water must be hot to properly extract flavor from the tea mix.

• Sugar
  Granulated sugar is typically used to sweeten the tea during brewing. Some versions may also use simple syrup for consistency.

• Sweetened Condensed Milk
  Adds both sweetness and creaminess. It is poured over the brewed tea and often used for visual layering in presentation.

• Evaporated Milk or Whole Milk
  Used to lighten the tea and enhance creaminess. It can also be substituted with half-and-half or coconut milk in dairy-free versions.

• Ice
  Crushed or cubed ice is essential to chill the drink and create the signature “iced” texture.

3. Basic Preparation Method

Below is the standard method of preparing Thai Iced Tea at home or in food establishments:

Ingredients (for 2 servings):

• 2 cups water

• 2–3 tablespoons Thai tea mix

• 2–3 teaspoons sugar (adjust to taste)

• 1/4 cup sweetened condensed milk

• 1/4 cup evaporated milk or whole milk

• Ice

Instructions:

1. Brew the Tea

   • Bring 2 cups of water to a boil.

   • Add 2–3 tablespoons of Thai tea mix and reduce to a simmer.

   • Let steep for 3–5 minutes for a strong flavor.

   • Strain the tea using a fine mesh strainer or cheesecloth to remove solids.

2. Sweeten the Tea

   • While the tea is still hot, stir in the sugar until fully dissolved.

   • Allow the tea to cool to room temperature or refrigerate it for quicker chilling.

3. Assemble the Drink

   • Fill a tall glass with ice.

   • Pour the cooled tea over the ice, leaving room at the top.

   • Add 2 tablespoons of sweetened condensed milk.

   • Top with 2 tablespoons of evaporated milk or whole milk.

   • Stir before drinking or leave layered for visual effect.

4. Commercial Preparation

In commercial settings, Thai Iced Tea is often made in larger quantities using pre-packaged Thai tea mix for consistency. Restaurants may prepare tea in advance, chill it, and pour it over ice when ordered. The cream layer is typically added last for visual appeal. In high-volume establishments, machines may be used for brewing, and sweeteners may be pre-mixed into the tea base.

5. Variations of Thai Iced Tea

There are several regional and dietary variations of Thai Iced Tea, including:

• Dairy-Free Version
  Coconut milk, almond milk, or oat milk can replace dairy to make the drink vegan or lactose-free.

• Less Sweet Version
  The sugar content can be reduced during brewing, or unsweetened milk alternatives can be used.

• Spiced Thai Tea
  Some versions include additional spices such as cinnamon, cloves, and star anise to create a more complex flavor profile.

• Thai Green Iced Tea
  Made with green tea instead of black tea, often using pandan for aroma and a light green color.

• Boba Thai Tea
  Tapioca pearls (boba) are added to the bottom of the glass, turning it into a Thai bubble tea.

• Alcohol-Infused Thai Tea
  Some fusion restaurants and bars add spirits like rum or vodka to create cocktail versions of Thai Iced Tea.

6. Nutritional Considerations

Thai Iced Tea is high in sugar and calories due to the use of sweetened condensed milk and added sugar. A typical 16-ounce serving can contain over 200 calories and 30 grams of sugar. Health-conscious consumers may opt to use low-fat milk, sugar substitutes, or reduced-sugar condensed milk to modify the beverage.

Despite its calorie content, Thai Iced Tea offers antioxidants from the tea base, especially when brewed from high-quality black tea leaves. However, commercial Thai tea mixes may contain food coloring and additives, which some individuals prefer to avoid.

7. Storage and Shelf Life

Brewed Thai tea can be stored in the refrigerator for up to 3–4 days without milk. It should be kept in a sealed container to maintain freshness. Once milk is added, the drink should be consumed within 24 hours. It is not recommended to freeze Thai Iced Tea, as this may affect the texture and flavor.

8. Availability of Ingredients

Thai tea mix is widely available in Asian grocery stores and online. Popular brands include “Number One” (also known as “ChaTraMue”) and “Pantai.” It is important to check ingredient labels for added coloring and artificial flavorings, especially if you are aiming for a more natural version of the beverage.

Sweetened condensed milk and evaporated milk are also commonly found in most supermarkets. For healthier options, some brands offer low-sugar or organic versions.
