Starbucks matcha drinks combine finely ground green tea powder with milk or water to create a smooth, slightly sweet beverage with a vibrant green color.
While matcha is often chosen for its earthy flavor and antioxidant benefits, it also contains caffeine — enough to provide a gentle lift without the intensity of coffee.
What is Starbucks Matcha?
Starbucks uses a pre‑blended matcha powder made from finely ground green tea leaves combined with sugar. This blend is whisked into hot milk for lattes or shaken with milk and ice for iced versions.
Key characteristics include:
- Base Ingredient: Japanese‑style matcha powder (green tea + sugar)
- Flavor Profile: Earthy, slightly grassy, subtly sweet
- Texture: Creamy when made with milk, lighter when made with water
- Serving Styles: Hot Matcha Latte, Iced Matcha Latte, Matcha Lemonade, Matcha Cold Foam
The sugar in Starbucks’ matcha makes it more approachable for those new to green tea, though it also increases calorie content.
How Much Caffeine is in Starbucks Matcha?
The caffeine in Starbucks matcha comes entirely from the green tea powder. The amount depends on the drink size and the number of scoops used.
Typical caffeine content by size (Hot or Iced Matcha Latte):2
- Tall (12 fl oz): 55–80 mg
- Grande (16 fl oz): 80–120 mg
- Venti (20–24 fl oz): 110–160 mg
- Trenta (30 fl oz, iced only): 120 mg
For comparison, a Grande Caffè Latte has about 150 mg of caffeine, and a Grande Iced Green Tea has only 25–30 mg. Matcha sits comfortably in the middle — more than tea, less than coffee.
Calories and Nutrition
Nutritional values vary depending on milk choice and size. The matcha powder itself contains sugar, so even without added syrups, the drink is sweetened.

Using non‑dairy milk or sugar‑free matcha (introduced in some markets in 2025) can reduce sugar and calorie content.
Ingredients Overview
Starbucks matcha drinks are built from a simple base, but each element plays a role in shaping the flavor, texture, and caffeine profile.
Matcha Powder: Finely ground green tea leaves blended with sugar.
Milk or Water: Base liquid for hot or iced drinks.

Matcha naturally contains L‑theanine, an amino acid that promotes calm focus, helping balance the stimulating effects of caffeine. This combination creates a smooth, energizing drink that’s both refreshing and satisfying.
