Thai Iced Green Tea Recipe

Heat water

Bring 900 ml of fresh filtered water to just under a boil — about 80–85°C (175–185°F). If you don't have a thermometer, bring to a simmer where small bubbles form but it is not vigorously boiling.

Steep tea

Add 8 g of Thai green tea blend (or strong sencha/bancha) to a heatproof teapot or infuser. Pour the hot water over the leaves and steep for 3–4 minutes for a robust flavor. Taste at 3 minutes; if you prefer stronger, steep up to 5 minutes but avoid over-steeping to prevent excessive bitterness.

Strain and cool

Strain the tea leaves through a fine mesh sieve or tea strainer into a heatproof container. Allow the brewed tea to cool at room temperature for 10–15 minutes, then place in the refrigerator for at least 20 minutes until chilled. (If you need it fast, transfer to an ice bath to cool more quickly.)

Combine dairy and sugar

In a mixing container or small pitcher, whisk together 120 ml sweetened condensed milk, 120 ml whole milk, 60 ml evaporated milk (if using), and 1 tablespoon granulated sugar until smooth and homogenous. The sugar helps adjust sweetness and thins the condensed milk slightly for easier pouring. Taste and adjust sweetness; remember the tea will be diluted with ice.

Chill mixture

Place the milk mixture in the refrigerator while the tea cools so both components are cold when assembled.

Assemble the drink

Fill two tall glasses with 1.5 cups of ice each (about 3 cups total used for two servings). Pour equal portions of the chilled brewed green tea into the glasses, filling to about three-quarters full.

Add milk mixture

Divide the sweetened condensed milk mixture between the glasses (about 150 ml per glass). Pour slowly over the back of a spoon or directly to create the classic layered look if desired. Stir gently to combine before drinking, or leave layered and stir at the table.

Garnish and serve

Garnish with an optional mint sprig and/or a lime wedge on the rim. Serve immediately with a straw or stirring spoon.

Notes on substitutions

For a lighter version, reduce sweetened condensed milk to 90 ml and increase whole milk to 150 ml. For vegan option, use sweetened condensed coconut milk and a plant-based milk (unsweetened soy or oat) in place of dairy.
