Why there is no precise caffeine count per glass
Tea-leaf quantity, brewing strength, steeping time and dilution are unknown for a particular shop drink. The ordinary-tea range below is not an actual minimum or maximum for Thai iced tea. Ask the seller about the tea and preparation.
An optional calorie model
Our separate editorial recipe adds sweetened condensed milk, evaporated milk and optional granulated sugar to ordinary brewed black tea, plus plain ice and water. Only ingredients are taken from the recipe source. All nutrition comes from USDA; shop portions and stronger tea may differ.
USDA records: compare the same edible weight
Each reference row is per 100 g. Food states and alternatives stay separate. Additional soda rows use the recorded can weight. Missing nutrients stay Unknown; a displayed zero can be a small value rounded to one decimal.

Portion scenarios and calculation
Assumptions: tea 120–240 g; condensed milk 20–40 g; evaporated milk 15–30 g; sugar 0–15 g. These weights are editorial models unless explicitly labeled USDA portions. Choose one alternative for each component; do not add alternative recipes together.
For every nutrient: USDA amount per 100 g × edible grams ÷ 100, summed across ingredients. The range is the minimum and maximum across the disclosed record alternatives and weight endpoints, calculated before rounding. Calories use whole kcal; g and mg use at most one decimal, with decimal ROUND_HALF_UP and no trailing zeros.
- 86 kcalFDC 173227 × 120 g + FDC 171275 × 20 g + FDC 171276 × 15 g + FDC 169655 × 0 g
- 229 kcalFDC 173227 × 240 g + FDC 171275 × 40 g + FDC 171276 × 30 g + FDC 169655 × 15 g
Combined scenario ranges: protein 2.6–5.2 g; fat 2.9–5.7 g; carbohydrate 12.7–40.5 g; fiber 0–0 g; total sugars 12.4–39.7 g; sodium 44.9–90 mg. Nutrient minima can come from different alternatives, so the low values do not necessarily describe one meal.
Ordinary black-tea reference only: FDC 173227 lists 20 mg caffeine per 100 g (nutrient 1057). At 120–240 g tea liquid, that scales to 24–48 mg caffeine. This is not a measured Thai-tea caffeine range or a bound for strong brews.
Plan the portion alongside other foods
Use a matching preparation and edible weight when logging each part of a meal. These guides explain separate foods or drink choices; their portion estimates are not interchangeable.
Common questions
Does thai iced tea have caffeine?
Yes, black-tea-based Thai iced tea contains caffeine. Hot Thai Kitchen identifies black tea as the base. USDA ordinary brewed black tea is only a reference scenario; it does not bound the caffeine in concentrated Thai tea.
How is this estimate calculated?
Use the listed USDA records and tea 120–240 g; condensed milk 20–40 g; evaporated milk 15–30 g; sugar 0–15 g. Multiply each per-100-g nutrient by edible grams divided by 100, then sum components. Alternatives are separate scenarios. The range describes the disclosed scenarios, not a confidence interval or official brand nutrition.
