Singapore teh: ordering teh, teh-O, teh-C and teh peng

What does “teh” mean in Singapore?

The National Heritage Board records tea-making and sharing as part of Singapore’s intangible food heritage. The word teh is a Malay-derived local term for tea, and the familiar coffeeshop ordering system combines it with descriptors for milk, sugar and ice. It is a menu language, not the name of a separate species.

A traditional cup of teh commonly uses brewed tea with sweetened condensed milk. The precise tea blend, strength and sweetness can differ between stalls. No single cups-per-day or caffeine figure can represent every serving.

How do the orders differ?

Teh generally means hot tea with condensed milk and sugar. Teh-O indicates tea without milk, normally with sugar; teh-O kosong removes the sugar as well. Teh-C traditionally uses evaporated milk instead of condensed milk, while teh siew dai requests less sweetness. Teh peng is served iced. Tea with ginger is commonly described as teh halia.

The letters O and C are practical ordering labels, not grades of tea leaf. Local shops may interpret shorthand or sweetness requests differently, so specify your preference when a dietary restriction matters.

Caffeine and ingredient cautions

Black tea contains caffeine even when mixed with milk or served over ice. Condensed-milk recipes typically add sugar; evaporated milk still introduces dairy. People avoiding milk proteins or managing sugar should confirm the ingredients instead of assuming that an order code guarantees a particular composition.

Why this belongs in the World Tea Reference

A culturally important tea-drinking vocabulary deserves documentation, but should be catalogued as a regional preparation and ordering practice. It must not be mistaken for a seventh tea-processing family or for a named cultivar.

Claim-level source review

Checked 26 October 2026. The following narrow findings are traceable to their original publications. Their presence does not certify every statement elsewhere in this article or authenticate individual tea products.

Singapore’s public HealthHub guidance defines teh as tea with sugar and condensed milk, teh O as tea with sugar but without milk, and teh C as tea with sugar and evaporated milk. This is a locally documented ordering convention, not a legal ingredient standard for every stall. [Ordering terminology: Read ordering terminology source ↗]

HealthHub uses kosong for no sugar, siu dai for less sugar, poh for weaker and gao for stronger. These modifiers help specify an order but do not measure the sugar grams or milligrams of caffeine in the finished cup. [Modifiers and measurement: Read modifiers and measurement source ↗]

The health authority notes that milk and sugar change calorie intake and that caffeine tolerance varies. A familiar drink name alone is insufficient for individual dietary or clinical decisions. [Nutrition boundary: Read nutrition boundary source ↗]

Singapore’s Health Promotion Board requires food-related claims to be scientifically verifiable and not misleading. A lower-sugar ordering phrase is a recipe choice, not evidence of disease prevention. [Food-claim boundary: Primary source ↗]

Still open: remaining article claims, relevant regional variations and source updates; product origin, composition and health effects require separate evidence.
