There is no single worldwide caffeine number for a Starbucks Venti matcha. Starbucks recipes, milk choices, drink format and country can change the nutrition panel. The current Starbucks menu and local nutrition sheet are the reliable sources for the drink you plan to order.
What official menus show
For example, Starbucks UK’s current nutrition PDF lists about 111.5 mg of caffeine for a Venti hot Matcha Green Tea Latte with its listed milk and about 113 mg for a Venti iced version with a listed soy drink. Those figures are market- and recipe-specific—not a universal Starbucks rule. Starbucks Australia publishes different nutrition values for its local iced matcha, and the US menu may present a different panel.
How to check your order
- Open the Starbucks site or app for your country.
- Select the exact matcha drink, hot or iced, and Venti size.
- Review the current nutrition and ingredient panel after choosing milk and customizations.
- Include the drink’s caffeine in your total for the day.
Do not use a Frappuccino value for a latte, or an older screenshot for a current recipe. If the panel is missing or changes at checkout, ask the barista or Starbucks customer support for the current figure.
Why the number can change
Matcha powder dose, serving size, sweetened or unsweetened powder, and recipe changes all affect caffeine. A product can taste mild without being low in caffeine, so taste is not a measurement.
Bottom line: use the current Starbucks nutrition panel for your country and exact Venti matcha format. For general context on matcha and coffee caffeine, see our matcha caffeine guide.
