In this article, we will explore the origins of Oliang, its cultural significance, and provide you with a step-by-step guide on how to make this refreshing beverage at home.

Oliang: A Brief Culinary Journey

Origins and Cultural Significance: Oliang, also known as Thai iced coffee or “iced black coffee,” has its origins in Thai-Chinese culinary traditions. The word “Oliang” itself is derived from the Teochew dialect, spoken by the Teochew people who migrated to Thailand. This aromatic coffee blend gained immense popularity due to its distinctive preparation method and unique flavor profile.

Ingredients and Preparation: Oliang is made using a special blend of coffee beans roasted with a mix of ingredients such as sesame seeds, corn, and soybeans. This unique combination imparts a robust and complex flavor to the coffee. The coffee is traditionally brewed using a “sock” or cloth filter, resulting in a strong and fragrant brew.

Making Oliang at Home: A Step-by-Step Guide


  • 1 cup of coarsely ground coffee beans (a blend of Arabica and Robusta works well)
  • 2 tablespoons of crushed sesame seeds
  • 1 tablespoon of crushed corn kernels
  • 1 tablespoon of crushed soybeans
  • 4 cups of water
  • Sweetened condensed milk or sugar, to taste
  • Ice cubes


  1. Prepare the Oliang Mix:
    • In a bowl, combine the coarsely ground coffee beans, crushed sesame seeds, crushed corn kernels, and crushed soybeans. Mix well to create the Oliang blend.
  2. Brew the Oliang:
    • Place the Oliang blend in a coffee sock or cloth filter. Boil 4 cups of water and pour it over the coffee blend, allowing it to steep and brew for about 15-20 minutes. The longer you steep, the stronger the flavor.
  3. Strain and Cool:
    • Once brewed, remove the coffee sock or filter, straining out the grounds. Allow the Oliang concentrate to cool to room temperature.
  4. Sweeten to Taste:
    • Add sweetened condensed milk or sugar to the cooled Oliang concentrate, adjusting the sweetness according to your preference. Stir well to ensure it’s evenly distributed.
  5. Serve Over Ice:
    • Fill glasses with ice cubes and pour the sweetened Oliang concentrate over the ice. The result is a refreshing and aromatic Thai iced coffee.
  6. Optional: Condensed Milk Swirl:
    • For an authentic touch, swirl a bit of condensed milk on top of the iced Oliang before serving.
