Lemongrass Iced Tea

Fragrant lemongrass iced tea is a clean, cooling drink with the briskness of black tea and the citrusy herbal perfume of fresh lemongrass. The stalks are gently simmered to draw out their aroma before the tea is steeped briefly, keeping the flavour bright rather than tannic. Lightly sweetened and served well chilled over ice, it works as a refreshing everyday drink, especially with Vietnamese-style meals, spicy food or hot-weather lunches. The character is crisp and aromatic, with enough sweetness to soften the tea without masking the lemongrass.

Why this recipe works

  • Clean herbal refreshment: Fresh lemongrass brings a bright citrus aroma that keeps the tea light and cooling.
  • Balanced sweetness: Sugar softens the tannins of the black tea without masking the lemongrass.
  • Short active time: Most of the work is simple simmering, steeping and chilling, with only a few minutes of hands-on preparation.
  • Easy to prepare ahead: The strained tea keeps well in the fridge, ready to pour over fresh ice when needed.

Timing notes

  • Cool before chilling: Let the tea come to room temperature before refrigerating so it chills evenly and keeps a clean flavour.
  • Add ice at the end: Pour over ice just before serving to avoid watering down the tea.

Ingredient notes

  • Bruise the lemongrass: Lightly crushing the stalk helps release its aromatic oils into the simmering water.
  • Use good black tea: A clean, brisk loose-leaf black tea gives structure without overpowering the lemongrass.
  • Adjust after steeping: Sweeten while the tea is still warm, then taste again once chilled as cold drinks can seem less sweet.

Make-ahead tips

  • Make it in advance: Store the strained, sweetened tea in a sealed container in the fridge for up to 3 days.
  • Keep ice separate: Chill the tea on its own and add fresh ice only when serving for the clearest flavour.

  1. Pour the water into a saucepan. Trim the lemongrass, then lightly bruise it with the back of a spoon to help it release its aroma.
  2. Add the lemongrass to the pan and bring to a gentle simmer over medium heat. Simmer for 8 minutes, keeping it just below a rolling boil.
  3. Remove from the heat and add the dried black tea. Steep for 3 minutes for a clean, brisk flavour.
  4. Strain into a heatproof jug, then stir in the granulated sugar until fully dissolved. Let the tea cool to room temperature, then chill until cold.
  5. Fill a glass with the ice cubes and pour over the cold lemongrass tea. Serve straight away.

Recipe notes

Tips

  • For a brighter lemongrass aroma, bruise the stalk well before simmering, but keep the simmer gentle so the tea stays clean-tasting.
  • If serving later, chill the strained tea first and add the ice only at the last moment to avoid diluting the flavour.

Substitutions

  • Replace granulated sugar with acacia honey for a softer sweetness; stir it in while the tea is still warm so it dissolves fully.
  • Replace dried black tea with dried-jasmine-tea for a more floral iced tea that still pairs well with lemongrass.

Storage

  • Refrigerate up to 3 days
  • Store the strained, sweetened tea in a sealed container in the fridge for up to 3 days. Serve over fresh ice cubes; if the tea tastes muted after chilling, stir well before pouring.
