Iced lemon tea is the Malaysian kopitiam staple. Every coffee shop pours it; every menu lists it; every Malaysian has an opinion on which kopitiam makes it best. Behind a serious bar, the iced lemon tea format becomes a surprisingly flexible cocktail base, citrusy, sessionable, low-ABV when you want it, easy to build on.
What a real iced lemon tea is
The Malaysian kopitiam version: strong-brewed black tea (usually a Ceylon or Boh blend), sweetened with sugar syrup, served over ice with fresh lemon wedges. The tea is brewed hot and concentrated, then cooled. Some kopitiams add a slice of preserved sour plum (asam boi) to amplify the sour-sweet contrast.
The character: bright, lightly tannic, sour-sweet, refreshing in 32°C heat. The original Malaysian iced lemon tea is one of the great hot-climate drinks.
What a fake iced lemon tea is
Bottled "iced lemon tea" from a tetra pak or PET bottle. Made from tea powder, citric acid, sugar syrup, and lemon flavouring. The flavour is one-dimensional and overly sweet.
If you are building cocktails on iced lemon tea, brew the base from real tea leaves. Bottled product will not work.
The base recipe (kopitiam-style)
- Strong-brew 10g of Boh black tea (or Ceylon) in 400ml of just-boiled water for 5 minutes.
- Strain. Add 50g of sugar (or 80ml of palm sugar syrup) while still hot. Stir until dissolved.
- Cool to room temperature.
- Refrigerate. Lasts 4-5 days.
To serve as a non-cocktail drink: pour over ice with fresh lemon wedges, optionally with a sour plum.
Three cocktails built on iced lemon tea
1. Long Island Iced Tea (the kopitiam version). Vodka + gin + rum + tequila + triple sec, equal parts (15ml each), plus 30ml iced lemon tea base, plus 15ml fresh lemon. Build over ice in a tall glass. The classic Long Island with the kopitiam tea base instead of cola. Higher-quality, less sweet.
2. Whisky Iced Lemon Tea. Whisky (45ml), iced lemon tea base (90ml), fresh lemon juice (15ml), 1 asam boi muddled in. Build over ice in a tall glass. The Malaysian whisky highball. Drinks like a low-ABV punch.
3. Iced Lemon Tea Spritz (low-ABV). Iced lemon tea base (60ml), Aperol or Campari (30ml), top with soda. Build in a wine glass over ice. Garnish with a lemon wheel and a sprig of mint. A Malaysian-Italian fusion that works better than it should.
The asam boi connection
Adding a preserved sour plum (asam boi) to iced lemon tea is a small kopitiam tradition that translates beautifully to cocktails. The salty-sour plum amplifies the tea's tannin and the lemon's acid simultaneously.
In a cocktail format: muddle one asam boi into the bottom of the glass before building. Or add 5ml of asam boi syrup. See our piece on asam boi in cocktails.

Frequently asked questions
What is a kopitiam-style iced lemon tea?
Strong-brewed black tea (Boh or Ceylon), sweetened with sugar syrup, served over ice with fresh lemon wedges. The tea is brewed hot and concentrated, then cooled. Some kopitiams add a slice of preserved sour plum (asam boi) to amplify the sour-sweet contrast. The character is bright, lightly tannic, sour-sweet, and one of the great hot-climate drinks in Malaysia.
How do I make iced lemon tea base for cocktails?
Brew 10g of Boh black tea (or Ceylon) in 400ml of just-boiled water for 5 minutes. Strain. While still hot, dissolve 50g of sugar or 80ml of palm sugar syrup. Cool to room temperature and refrigerate; the base holds 4 to 5 days. Use 60 to 90ml of the cooled base in cocktails as a citrus-tannin foundation, in place of soda or cola in long drinks.
Can I substitute bottled iced lemon tea for fresh-brewed?
No. Bottled iced lemon tea (tetra pak or PET bottle) is made from tea powder, citric acid, sugar syrup, and lemon flavouring. The flavour is one-dimensional and over-sweet, which throws every cocktail balance off. Brew the base from real tea leaves; the extra fifteen minutes of work makes the difference between a kopitiam-inspired cocktail and a sticky soda. Bottled product will not work.
What is the asam boi connection to iced lemon tea?
Adding a preserved sour plum (asam boi) to iced lemon tea is a small kopitiam tradition. The salty-sour plum amplifies the tea's tannin and the lemon's acid simultaneously. In a cocktail, muddle one asam boi into the bottom of the glass before building, or add 5ml of asam boi syrup. The combination gives a Whisky Iced Lemon Tea highball a depth that the lemon and tea alone cannot reach.
