About Teh O Siu Dai
Teh O Siu Dai is a staple beverage in Singapore's hawker centres, appreciated for its simplicity and lighter sweetness. The name breaks down into 'Teh' (tea), 'O' (without milk), and 'Siu Dai' (less sugar), making this a less-sweet black tea drink. Typically, it’s brewed fresh with black tea dust or leaves, strained into clear glass mugs, and served hot or occasionally iced. It's a popular choice for those who want a caffeinated drink without the heaviness of condensed milk or the overbearing sweetness found in other kopi or teh variations. At hawker stalls, Teh O Siu Dai is prepared quickly, with boiling water and a spoonful of tea dust, then stirred with just a dash of sugar. The resulting drink is bright, tannic, and refreshing—with a flavour that's a little more robust and less creamy than Teh Tarik or Teh Si. For those watching their sugar intake or calories, Teh O Siu Dai is a reasonable option, containing around 25 kcal per 100g, virtually no fat or protein, and 3g carbohydrate (mostly from sugar). If you want it even healthier, you can ask for 'kosong' (no sugar), which drops the calorie count further. Ordering tip: Specify 'siu dai' clearly, as hawkers may default to the regular amount of sugar for 'Teh O.' For those who prefer cold drinks, request "ice"—but remember extra sugar might be added unless you clarify. With low calories and minimal sugar, Teh O Siu Dai is a solid option if you’re pacing yourself through a hawker meal or just need something refreshing without heavy calories.
How to Make Teh O Siu Dai (Traditional & Healthy Version)
Teh O Siu Dai is a beloved beverage found in every Singaporean kopitiam (coffee shop) and hawker centre, enjoyed by locals throughout the day. Translating to 'tea without milk, less sugar', Teh O Siu Dai reflects Singapore’s rich multicultural heritage and the city’s penchant for customizing everyday drinks. This drink is a lighter, more health-conscious alternative to the classic Teh O, yet retains the robust, aromatic flavors of local black tea, sweetened with just a touch of sugar. Its simplicity and refreshing taste make it a staple among Singaporeans seeking a guilt-free, flavorful pick-me-up. The origins of Teh O Siu Dai lie in Singapore’s vibrant kopitiam culture, where ordering drinks in 'Singlish' shorthand is a daily ritual. This beverage is not only enjoyed for its taste but also as a symbol of Singapore’s uniquely blended cultures and traditions. Perfect for breakfast or lunch, Teh O Siu Dai is both comforting and energizing, making it a great choice for anyone looking to experience authentic Singaporean flavors without excess calories.
Ingredients(for 1 glass (about 200ml), typical kopitiam portion)
- 2 tablespoons Loose black tea leaves (local 'teh' blend preferred)
- 500 ml Water (freshly boiled)
- 1 teaspoon Rock sugar (adjust to taste for 'siu dai' (less sweet))
- 1 small leaf Pandan leaf (knotted, optional for aroma) - optional
- 2 thin slices Lemon slice (optional, for a refreshing twist) - optional
- as needed Ice cubes (for iced version (Teh O Siu Dai Peng)) - optional
- 1/2 teaspoon Stevia or erythritol (optional, as sugar substitute) - optional
- 1 Tea sock (traditional brewing tool) - optional

Instructions

- 2
Add the loose black tea leaves to a tea sock or directly to the pot. Pour the boiling water over the leaves.

Using a tea sock helps achieve the signature kopitiam taste and makes straining easier.

Let the tea steep for 3–5 minutes, depending on your preferred strength. Stir occasionally.
5 minutes
For a more robust flavour, steep slightly longer, but avoid over-extracting to prevent bitterness.

Strain well to get a clear, smooth cup of tea.
Why This Dish is Healthy
This healthy Singaporean beverage is an excellent alternative to sugar-laden milk teas and soft drinks. By using less sugar and omitting dairy, Teh O Siu Dai is both waistline-friendly and heart-healthy, catering to those watching their calorie and sugar intake. Its simplicity allows you to enjoy a refreshing drink anytime, without worrying about excess carbohydrates or fats. Perfect for anyone seeking a traditional taste of Singapore with a modern, health-conscious twist.
Teh O Siu Dai is naturally low in calories and contains no fat or cholesterol. Black tea is rich in antioxidants such as polyphenols, which support heart health and may aid in reducing the risk of chronic diseases. The beverage provides a mild caffeine boost without the excess calories from milk or sweetened condensed milk. Pandan leaves, if used, add a subtle aroma and contain trace minerals. Choosing less sugar or a natural sweetener further reduces the glycemic impact, making it suitable for most diets.
