How to Make It

  • 1

    Place 2 tablespoons of Thai dark roast coffee powder into a coffee filter set over a mug or a French press. Ensure the coffee is finely ground for optimal flavor extraction.

  • 2

    Pour 250ml of boiling water over the coffee grounds, making sure to saturate all the powder evenly. Allow it to steep for a robust 4-5 minutes for a strong brew, or longer if you prefer an even bolder taste.

  • 3

    Carefully strain the coffee concentrate into a heatproof glass, ensuring no grounds remain. If using a French press, slowly push the plunger down. You'll have a dark, fragrant liquid.

  • 4

    Stir in 2-3 teaspoons of sugar until completely dissolved. For a traditional 'Oliang,' this is sufficient. For a creamier 'Oliang Yok Lor,' add 1-2 tablespoons of sweetened condensed milk now.

  • 5

    Fill a tall serving glass generously to the brim with ice cubes. The ample amount of ice will chill the hot coffee quickly without excessive dilution.

  • 6

    Pour the sweetened, strong coffee over the ice. For 'Oliang Yok Lor,' you can optionally drizzle a final layer of 1-2 tablespoons of evaporated milk on top, creating a creamy contrast before serving. Stir well before enjoying.

Frequently Asked Questions

What is Oliang?

Oliang is a Thai iced coffee made from strong dark roast coffee and sugar; for the creamier 'Oliang Yok Lor', sweetened condensed milk and evaporated milk can optionally be added. It is a popular street food beverage often consumed during meals or as a refreshing drink in warm weather.

What is the difference between 'Oliang' and 'Oliang Yok Lor'?

Can I use regular dark roast coffee instead of Thai coffee powder?

How can I make my Thai iced coffee less bitter?

To reduce bitterness, you can try steeping the coffee for a slightly shorter time or adjust the amount of sweetener to balance the coffee's intensity.
